Tooth Sensor Watches Your Mouth
Transcript hided
[dialog: 1-14]
A person’s mouth says a lot about them. Sounds obvious, but I’m talking less about what vocalizes and more about the way it behaves when we eat, drink, speak or even cough.
Researchers at National Taiwan University believe that monitoring such oral behavior can provide doctors with a wealth of information about a patient’s dietary habits, dental hygiene and overall health.
To test their idea, they built an accelerometer-based oral sensory system to identify how a mouth is being used based on the movement of its teeth. Placed in the mouths of eight people, a prototype system correctly recognized each person’s oral behavior up to 94 percent of the time. [Cheng-Yuan Li et al., Sensor-Embedded Teeth for Oral Activity Recognition]
The researchers now want to build a wireless version that might someday fit inside a fake tooth or attach to a pair of braces. The sensor could send you or your doctor a message when you’re not sticking to your diet or not keeping your promise to quit smoking.

4 Sky Events This Week: Harvest Moon, Green Giant, and Fall Equinox
[attach]128739[/attach]
This week two of the brightest planets join forces, and sky-watchers celebrate the change of seasons with a bright full moon.
Saturn and Venus.
Starting on Monday, September 16 after sunset, Venus and Saturn will be having a close encounter that will last most of the week. Low in the southwest sky, the second planet from the Sun will be the first visible—as the brightest star-like object in the entire heavens.
Look carefully next to Venus—binoculars may help—and fainter Saturn will pop out of the glare of dusk. Remember that since the two worlds are hot on the heels of the setting sun, they sink below the horizon less than an hour later.
The lord of the rings will pass only 4 degrees above the goddess of love—less than the width of your three middle fingers at arm’s length. As the week progresses both planets will appear lower in the sky each night with Venus sliding a bit towards the left of Saturn.
Even the smallest backyard telescope will show off Saturn’s iconic rings and even some of its brightest moons—like Titan and Enceladus.
Full Harvest Moon. Watch the near full moon rise soon after sunset, Wednesday, September 18, and reach official full moon status at 7:13 am EDT the next morning around when sun rises.
The full moon nearest the fall equinox is known as Harvest Moon and was probably coined by farmers in the Northern Hemisphere since its added light is said to have helped them gather in their crops.
Binoculars will easily show off the moon’s dark patches visible with the naked eyes. Called plains or maria in Latin, meaning seas, these are vast, ancient lava plains formed over billions of years ago when magma from the moon’s interior spilled out onto the surface, triggered by giant asteroid impacts.
With telescopes, the views get even more exciting—you can get sharp views of hundreds of ridges, mountains, cliffs, and craters up close.

Moon and Uranus. All night long on Thursday, September 19 the seventh planet from the Sun, Uranus, will park itself near the moon.
The green giant is only 4 degrees away from the moon. The cosmic odd-couple will appear about four degrees apart in the sky—equal to 8 full moons side-by-side.
The green-colored ice giant has four times the width of Earth, but since it lies nearly 1.9 billion miles (3.1 billion kilometers) away from Earth, it’s barely visible to the naked eye—and only in very dark, pristine skies.
With the glare from the nearby moon, binoculars will be your best bet in spotting Uranus. Just look for a tiny greenish-blue disk in the field of view. By the way, the absorption of red light by methane in the atmosphere is what gives Uranus it’s cool cyan coloring.
Equal Day and Night. Autumn equinox is at 4:44 pm ET on Sunday, September 22, and officially marks the time of year we kick off the fall season in the northern hemisphere and the start of spring in the southern hemisphere. The word equinox comes from Latin meaning “equal night” and refers to the 12 hour long day and night that occurs only on this particular day of the year.
Looking at the mid-day position of the sun over the summer season, Northern Hemisphere sky-watchers will notice that it has been slowly sinking closer to the southern horizon, and creating ever longer shadows.
It’s only on the spring and autumnal equinox that the Sun rises due east and sets due west.
Astronomically speaking, the September equinox marks one of the four major turning points in the cycle of seasons. The Earth spins on its axis, which is tilted at 23.5 degrees with respect to its orbital plane. On these days, however, the Earth’s axis is neither tilted away nor towards the Sun, but has both northern and southern hemispheres experiencing equal amounts of sunshine.

Article 4
Insect leg cogs a first in animal kingdom
Toothed gears enable young plant hoppers to synchronize limbs for jumping.
[attach]128738[/attach]
If you are a young plant hopper, leaping one metre in a single bound, you need to push off with both hind legs in perfect unison or you might end up in a spin. Researchers have discovered that this synchrony is made possible by toothed gears that connect the two legs when the insects jump.
Zoologists Malcolm Burrows and Gregory Sutton at the University of Cambridge, UK, say that this seems to be the first example in nature of rotary motion with toothed gears. They describe their findings today in Science.
The researchers' micrographs and videos of the jumping mechanism of the plant hopper Issus coleoptratus show that the joints that connect the hind legs to the body have rounded shapes and a series of tiny intermeshing teeth, each about 20 micrometres long.
When the insect jumps, the cog teeth join so that the two legs lock together, ensuring that they thrust at exactly the same time (see video above and image at left). “The gears add an extra level of synchronization beyond that which can be achieved by the nervous system,” says Burrows.
Infant plant hoppers, known as nymphs, can take off in just 2 milliseconds, reaching take-off speeds of almost 4 metres a second (see video below). For motions this rapid, some mechanical device is needed to keep the legs synchronized and to avoid lopsided jumps that might lead to the insects spinning out of control. The problem does not, however, arise in all jumping insects: whereas the attachments of plant hoppers' hind legs are adjacent to each other, the legs of grasshoppers and fleas attach to opposite the sides of the body and move in parallel planes. This helps to stabilize the insects and even enables them to jump one-legged.

Rotary club
The cog feature is analogous to the toothed gears that have been used in rotating machinery for millennia: they were described by Aristotle and Archimedes more than 2,000 years ago and they seem to have been used in ancient China even earlier. But, like the wheel, this human invention previously seemed to have little precedent in the natural world.
Gears are not the only mechanical solutions that were long thought to be unique to human engineering and then found to have been mastered by evolution: The screw-and-nut system is another example. In 2011, Alexander Riedel of the State Museum of Natural History in Karlsruhe, Germany, and his colleagues reported a screw-thread joint in the legs of a weevil beetle.
Riedel considers the latest work on Issus “significant and exciting”. He says that it adds to the view that “most of the basic components of engineering have been developed in the natural world”. The reason that gears are not more common, Riedel adds, might be because there are different ways to synchronize limbs. Honeybees, for example, “couple the movement of both wings to stabilize their flight by using pegs, not as moving gears, but more like a Velcro.”
Curiously, the gears are found only in the plant hopper's nymph stage. When it sheds its exoskeleton for the last time to reach full adulthood, the gears disappear. In adults, the legs are instead synchronized by a simple, frictional-contact method.
Burrows and Sutton are not yet sure why this is so, but it might be because of ease of repair. “If a gear breaks it can’t be replaced in adults,” says Burrows. “But in nymphs, a repair can be made at the next of several moults.” Another reason might be that the larger and more rigid adult bodies make the frictional method work better than the gear mechanism, he adds.

Seeking the loneliest whale
[attach]128742[/attach]
An enigmatic whale roams the North Pacific, and next year Bruce Mate will lead a monthlong expedition to find it. Mate, director of Oregon State University’s Marine Mammal Institute in Newport, is no revenge-obsessed Captain Ahab. And the object of the quest is no ferocious leviathan: It is probably one of the generally meek baleen whales that prey on creatures close to the base of the food chain.
No one has ever seen this particular whale (“that they know of,” says Mate), but researchers know it’s out there. Its distinctive 52-hertz calls — similar to those of blue whales and fin whales but higher in pitch — have been recorded since 1989 by various researchers and the U.S. Navy.
Scientists have some notions about the mystery whale: It’s probably a male, says Mate, since its calls pierce the seas only during mating season. The whale has been tracked swimming as far as 11,000 kilometers in a single season, so it’s apparently healthy. Because the whale’s path doesn’t seem to line up with those of other species inhabiting the same region, the cetacean has been dubbed by some “the loneliest whale in the world.”
Mate doesn’t buy that moniker for a number of reasons. For one thing, he says, females typically don’t respond vocally to a male’s mating calls; they simply show up, so scientists would not have heard them. He also doesn’t think it’s the last member of an unknown species hunted to near extinction. Instead, it’s more likely to be a hybrid between two known species, or possibly an individual with a malformation in its sound-producing organs — the cetacean equivalent of a lisp. “It wouldn’t surprise me to find a large number of other whales in his vicinity when we find him.”
In fact, Mate is counting on it. Although the expedition will be funded by a team of documentary filmmakers searching specifically for the falsetto whale, Mate hopes to tag about a dozen other whales. That will give him a rare chance to learn what whales do between feeding season, when they gorge themselves to build up fat stores, and breeding season.
“We’re trying to track these whales from the season we know to the season that we don’t,” he says. “There hasn’t been an experiment yet where we didn’t have “an ‘a-ha’ moment. — Sid Perkins

Article 6
Are E-Cigarettes a Boon or a Menace?
A new study says they may aid folks who want to quit smoking. But doctors fear there's a darker side to the electronic devices.
[attach]128741[/attach]
Electronic cigarettes may produce an aerosol vapor instead of smoke, but two new studies raise burning questions about their uses and risks.
E-cigs—as these battery-operated nicotine inhalers are commonly called—are increasingly popular, with a Wells Fargo financial analyst predicting that U.S. sales will double this year, going up to $1.7 billion.
Their visibility is becoming ever greater as well, with television and online marketing campaigns that feature celebrities like Jenny McCarthy and Stephen Dorff touting the pleasures of what they describe as more socially acceptable, "guilt-free" smoking.
The reasoning behind such claims is that e-cigs, which have the look of conventional cigarettes stylishly updated for the techno-age, produce vapor instead of ash or smoke. They also generally deliver lower amounts of nicotine than conventional cigarettes-a feature that may make e-cigarettes useful as an aid to smoking cessation.
Research Urgently Needed
Whether that is so was the focus of a study published in The Lancet, which concluded that e-cigarettes were statistically comparable to nicotine patches in helping smokers quit over a six-month period.
But this was only the first study to compare e-cigarettes to an already established quitting aid. "There is still so much that is unknown about the effectiveness and long-term effects of e-cigarettes" that more research is "urgently needed," cautioned lead researcher Chris Bullen, director of the National Institute for Health Innovation at the University of Auckland in New Zealand.
In that vein, Alexander Prokhorov, a smoking cessation expert at Houston's MD Anderson Cancer Center who was not involved in the study, commented, "I'm glad that there is finally some tangible research starting to appear." But several aspects worry him. "Nicotine is not a neutral substance," and in addition to being highly addictive, "it can be a poisonous substance."
Because e-cigs mimic the look and rituals of conventional cigarette smoking, there is a danger that rather than e-cigs helping you quit, "you may just switch to this product and continue using it," Prokhorov said. And since a smoker's dependence on nicotine remains, there is a risk for a relapse to smoking conventional cigarettes.
Not a Risk-Free Alternative
Still, wouldn't there be some potential benefit to using only electronic cigarettes as an alternative to conventional cigarettes? "There is no question that e-cigarettes deliver less toxins than conventional cigarettes," said Stanton Glantz, director of the University of California, San Francisco's Center for Tobacco Control Research and Education. They may have as little as one-tenth of the toxins inhaled from burning tobacco, he said. (Related: "Cigarettes vs. e-Cigarettes: Which Is Less Environmentally Harmful?")
But that's not the entire story, he emphasized. "Whereas e-cigarettes are less dangerous than regular cigarettes, in an absolute sense they are negative," because they contain a number of toxic chemicals and ultrafine particles in addition to nicotine, and secondhand e-cig vapor could be harmful.
Moreover, he continued, "most people who use e-cigarettes also continue to use regular cigarettes; they are dual users. That means they are probably suffering all the risks from smoking."
There is also a quality control issue for e-cigarettes, both Glantz and Prokhorov agreed. Unlike prescription nicotine patches, no electronic cigarettes have been approved for therapeutic use by the U.S. Food and Drug Administration.
"Further research is needed to assess the potential public health benefits and risks of electronic cigarettes and other novel tobacco products," said FDA spokesperson Jennifer Haliski. (Although the FDA's authority extends only to those e-cigs marketed for therapeutic purpose, with none having gained approval, it has announced its intention to propose broadening regulations to encompass additional categories of tobacco products that would include all electronic cigarettes.)
That's an important point, said Glantz, because the Lancet study's bottom line is that electronic cigarettes "are no worse than nicotine patches, but they are no better either." That leads to the question: "Why would you use something that has not been tested when there is something [with] quality control and [that] has been tested?"
Gateway Cigs for Teens?
Another question, about the average age of electronic cigarette users, brings us to the second study. This one, conducted by the Centers for Disease Control and Prevention, shows that the number of U.S. middle and high school students using e-cigarettes doubled between 2011 and 2012, bringing the number nationwide who had tried e-cigs to 1.78 million.
That statistic is disturbing, said Tim McAfee, director of the CDC's Office on Smoking and Health, because about 90 percent of all smokers begin in their teens. E-cigarettes may be particularly attractive to youngsters because they are sold in a broad array of flavors, including cherry, vanilla, and even bubblegum.
"We know that this makes these products more appealing to children," he said. "The worry is that it is going to acclimatize kids to the behaviors that are like smoking. Until proven otherwise, we need to assume that this may increase their chances of taking up smoking with burn [conventional] cigarettes." Prokhorov shares that worry.
"My major concern is that this will be a gateway behavior, a potential risk of getting kids hooked on nicotine for life," he said. That's also why Glantz favors greater regulations, including banning the use of flavors (which are prohibited in conventional tobacco cigarettes) as well as prohibiting the sale of e-cigs to minors.
"In the current world, where cigarettes are ubiquitous with a marketing budget of $8 billion a year, we have to be careful and not make it easy" for vulnerable children to start using tobacco, said McAfee, whose budget for the CDC's 2012 Tips from Former Smokers campaign was $54 million.
"You go on YouTube and see how e-cigarettes are being glamorized, making smoking look sexy and rebellious," he said, which are the very elements that research has shown will attract kids to smoking. This is why media critics are comparing current e-cig ads to the ubiquitous cigarette ads of the 1950s, he added.
But going back to that era would be a mistake, said Prokhorov. "Psychologically, our society has just started to enjoy a tobacco-free and smoke-free life," he said. "The renaissance of cigarettes in e- or any other form is not a pretty picture."

The author is talking about the use and risks of e-cigarettes.
Since there is still much unknown about the effectiveness and long-term effects of e-cigarettes, more researches are urgently needed.
E-cigarettes is not a risk-free alternative in that it contains more toxins compared with conventional cigarettes that contain almost nicotine.
People worry that the attraction of e-cigarettes appeals to teens and it acts as gateway cigs for teens.

(1) No test is done to approve the nonexisting negative potential from the vapor or any chemicals in the e-cigratee. (2) The addition to the nicodin (not sure about the spelling) is hard to quick, as a result, many people start to be dual smoker, they smoke both type in the same time, which raise the health risk up. (3) The most concern is for the teens, who are so facinated about the appealing e-cigratte, which consists of many different flavoring. In short, before any tests been done to show no potential risk in the uses of the e-cigratee, we better forestall the negative use of it.

Scientists are trying to seek a mystery whale who has never been seen but whose sound has been reocred.
Scientists think that this whale is a male and is healthy.This whale may be a a hybrid between two known species, or possibly an individual with a malformation in its sound-producing organs.

E-cigarettes are thought to be a good way to quit smoking.And their market are growing quickly in recent years.
But E-cigarettes may be not a good choice.
More researches on E-cigarettes are urgently needed.Some researches showed that E-cigarettes have no benefits on quitting smoke and that in some times E-cigarettes may lead to a worse condition.
Most people who use E-cigarettes are still smkoing,too.And E-cigarettes have no further tests and resarches on it.No laws or regulations on E-cigarettes has been made.People do not know what E-cigarettes will bring to us.
E-cigarettes have a great attraction on chiledren and teenagers.Children who use E-cigarettes may smoke when they grow up.
But at least E-cigarettes bring us a tobacco-free and smoke-free life.

E-cigarettes are increasingly popular, because people feel “guilty-free” when they use E-cigarettes, and E-cigarettes deliver fewer toxins.
However, E-cigarettes may not be a good product due to some concerns:
Deliver nicotine, possibly causing nicotine-additive
May cause user use conventionally cigarettes again.
Long-term effect is unknown, not tested and approved by government.
Commercial campaigns tempt teenage to use cigarettes.
Conclusion: E-cigarettes is not better than conventional cigarettes. More researches are needed.

Attitude: questioning -
Phenomenon : E-cigarette is becoming increasingly popular.
The author point out 3 questions of E-cigarette, and give a deep analysis
1. The effectiveness of using E-cig in a long term remains unknown
2. Although E-cig replace smoke with vapor, but whether E-cig contain fewer risks than conventional cigarette?
Answer: E-cigarette contains less nicotine but more other harmful things, the risk is equal to the conventional smoking.
3. The group of people who largely use E-cig is teen, and E-cig is being glorified, the horrible circumstance is that they may grow interest on smoking.

Author's attitude: Negative
Struture:
-Some are worried that E-cigarette has little influence to help people quick smoking.
-Smoking E-cigarette is not worse than real cigerrate but not better either.

2.The risk of e-cig.
3.The benefits of e-cig:can help people no more be addicted to smoking.Since nigotin is bad for health.However it cannot absolutely solve this problem because people just switch from one smoking method to another.Besides it brings second hand smoking.
4.The e-cig is also popular among adolecents.The use of e-cig increases and this phenomenon is disappointing.Children are more likely to get contact with smoking.And media help to spread the influence of e-cig.People should limit the number of e-cig to children.We should not go back to a former era,and we cannot stop the development of e-cig.

TIME2：01‘52'' The two brightest planets Venus and Saturn will be shown on 18, sepetember. They will gradually low down thier position in the sky. Binoculars can be applied to watch them more clearly. A harvest moon which is known as the indication of harvest autumn by northern famer also will be shown on 18th, September. With binoculars, people can see more such as mountains on the surface of the moon
TIME3: 01'43'' Uranus will come close to the moon. People can barely see Uranus. But on 19th, September, with the help of Binoculars people can see it. 22th, September marked the equal day. It is the only day for people in the northern sphere have a day with 12 hours day and 12 hours night. Also the people in Northen sphere and southern sphere will share the same amount of sunshine on this day
TIME4: 01'41'' The cog mechanism of the rear leg enables the plant hopper jump stably and two legs work simultaneously. But another mechanisim enables the grasshopper to jump with one leg
TIME5: 01'42'' The cog mechanism is not the only engeering mechanium applied in the natural world. Another example is the screw and nut system in the body of velvi beetle. It seems that the evolution allow the creatures to the advantage of the engeering system. But the cog mechanism is no longer used in the adult of plant hopper. One reason is that the body is too big to adpat is mechanism. The another reason is that the system can not be reparied for the adult
TIME6: 02'02'' A research team will take a expedition to do study for a special whale. Some think that this whale is almost extinct and the voice they hear is from a male duirng the mating season. But Mate thinks this whale is the result of a hybriid of two existing species.
Obsatcle: 05'31''
Main idea: The electrical cigarette and its merit and flaw. and the concern from people
Attitude: neutral
Structure:
==> more and more electrical cigarettes are adapted by people who smoke
==> it can help to stop smoking the real cigarettes in short time
==> it is less toxic than real cigarettes
==> some people may smoke both the real one and the electrical one simultaneously
==> the electrical cigarette can produce some special toxin comparing with real one
==> the afffect of the electrical cigarette to the secondhand smoker is worse
==> more and more young children will start to smoke because the flavour and the packing of the electrical cigarette

Whether the E-cig as good as they claim?
To give the proper answer, people need more reaserches.
Actually, e-cig has more types of toxic in addition to nicotine and their vapor is harmful too. Morever, the dual risk will be brought to the somkers who use both the conventional and e-cig.
The various flavors for children and teenager are charming attraction to lead them to the conventional cig.
However, neither of them is a good picture.

It talks about someting special about the planets. And we can have a clear sight of the surface of the moon.
Time 3 2:40.15
Two things. The first is that Uranus, the 7th planet, which is hard to be visible to the naked eyes, is the nearest to the Moon and can be somehow visible. The second thing is that the autumn equinox is at 4:44 pm ET Sun. Sep. 22, which means that the earth spin on its axis and the start of the fall.

Some findings of the plant hopper that has toothed gears and inside legs.

Time 7 5:04.57
The electronic cigarettes is becoming popular, but there are two question about it as we are unknown about the effectiveness and long-term effects.
The first is that someone believe e-cigs can help smoking cessation because of less toxins than conventional cigarettes. However, they may be the substance of cigarettes and there is some report show that people use them without cessation of smoking.
The sencond is that it shows that the number of teens who use the e-cigs is doubling than before which means that there is a potential risk of getting kids hooked on nicotine so that they will develop addicted to cigarettes when they grow up.

Plant copper jumped with two legs connected that helps them to jump high.
【1:46】
People began to use gears in machine many years ago. The pricinple can be found in nature. However, gears are not usual in nature. Plant copper use infriction system instead of gears. Because gears are easy to repair and bigger and more rigid bodies make the friction system work better than gears.

How do plant hoppers jump?
Toothed gears.Two legs jumping together.
__________
time:1:42.08
Plant hoppers are the first animals that people found gears in their bodies.
A guess:many elements in human engineering come from nature.
Hoppers have these gears in their childhood but not have them when they become adults.
Guess reason:easy to repair broken gears when they are young;adults are good at moving their legs together than gear mechanism.

Researchers are now trying to find a whale which is witnessed by many people but never found or catched.
Researchers think that this whale is male,healthy and probably longly.
But Mate thinks that this whale is not the last one of its speices.Researchers may not discovery them and once they find this whale,they may find other same species.Also he deduced that this whale may be hybrid.
The research is still continuing.

time:5:37.61
Electronic-cigarrets are poplular these days.People think they can replace the conventional cigarrets and help smoke cessation.
However,there are some concerns about E-cigs:
1 Futher researchs are needed.
There are many things unknown.
Researchers worry that people move their smoking habit from conventinal cigarrets to E-cigs.
2 Not risk-free
Many things are unknown.E-cigs also contain many toxic elements.
People may use E-cigs and convential cigarrets at the same time so that they suffer from both sides.
E-cigs are not received in public and may be harmful to public health(need futher research)
3 Gateway behavior
E-cigs have different flavors.They attract many teenagers(sexy and rebellious when use E-cigs)
suggestion:don't use flavors and more studies and more attention

obstacle-7'39
the passage evaluate the E-cigs.e-cigs can reduce risk in theory and people are able to enjoy the same from e-cigs as theconvential cigarettes. However,some studies shows that E-cigs might not be absolutely safe for the reasons that people might ues the E-cigs and the conventional one together, and the teenagers behavior also should be took into account. So, further researches are need to be conducted.

Author's attitude: Support (+)
Article structure:
1) Introduction of argument: e-cigs might not be helpful and healthy as people think.
2) Further studies need to be done:
-- low nicoine doesn't mean risk free, need to do some tests on the current products.
-- FDA hasn't approve the products yet.
-- 2nd hand low-nicoine vapour is also harmful for the people don't smoke.
-- it could be attractive to young people.
3) Relative tests need urgently to be completed.

Topic:The E-cig is a Boon or a Menace.
Attitude:neutral
Structure:
-Research Urgently Needed,and the E-cig may not help you to quit smoking.
-The E-cig is not a risk-free alternative because of the second-hand smoking.People may smoke more regularly than usual thus be more at risk.
-Teens may get addicted from smoking the E-cigs.

Speaker: Taiwan researchers can infer their patients oral behaviors by putting a sensor into their mouth.
They can detect some diseases like dental diseases and even test whethor or not their patients have started quit smoking.
Time 1: 2'20" Saturn and Venus will overlap in this week.
The largest full moon will show at 7:16 am, and u will see the clearest views on moon.
Time 2: 2'15" Several stars will get close to moon on Sep.16, and several of those will be hard to find by naked eye.
On Sep.22, it will be a special day that has a equal day and a night, so it is called equinox.
Besides that, at that day, the earth axis is located in the middle of the earth, making both sides of the planet experience the same amount of sunshine.
Time 3: 2'09" Insects are recently discovered by scientists that they need to jump by the help of their cog teeth.
Some insects have special device to avoid spinning around.
Time 4: 2'20" The discovery of a kind of beetle means that some components of engineering are originated from nature.
Gear system has initially been used in China, however, it is not very common to find its origin in natural world, such as honeybees, which use pegs to fly not gears.
Untill the discovery of plant jumper, we know gear system does have a origin. But the adult will not use this system.
Time 5: 2'47" Scientists decided to start a expidenture to find a special whale, who is detected by its sound.
Analysing the sound, they presumed that it seems to be a male whale who is seeking for mating and it has a group, however, the truth may be just a normal whale with malformation in sound-producing organs.
But even so, the expidenture is still underway.
Obstacle: 7'10" Main idea: Pros and cons of smoking e-ciggrate.
Attitude: negative
(1) E-ciggrate gets popularity: Nowadays, increasing people has alter to smoke e-ciggrate instead of conventional ciggrate.
Stars even in the ads to promote smoking e-ciggrate.
(2) Lack of research: Untill now, there are limited research on the long-term effect of using e-ciggrate.
(3) Potential dangers: e-c still has a small amount of nicotine which is harmful to people's fitness.
Besides nicotine, there are some other toxic material existed in the vampor of e-c.
People might also be the dual smoker: smoke both e-c and convential ciggrate.
(4) Effects on teenagers: Increasing teenagers are attracted to smoke e-c, as the ads show positive effect on smoking their products.
