Scientists find a new communication way among plants: through sound wave. Such conclusion are drawn from experiments by ruling out factors such as light, touch and chemicals. The result has a positive impact on crop yields and food supplies.
S2: 02:10
Dolphins' diets are ray-finned fish. Mostly is a kind of fish live in seagrass. Results suggest that the data of scientists are find.
S3: 03:30
U.S House have passed bills to avoid the global crisis of helium supply by keeping helium fluid. Helium is extracted from natural gas and has good industrial function.
S4: 03:08
Global demand for helium is increasing. A giant energy company in Russian is signing agreement to provide helium supplies to satisfy demands. The helium will not run short but the increase in price will hurt. So equipment and systems aiming to recycle or reduce the assumption of helium is necessary.
S5: 04:30
Scientists are trying to find out how moon generated. Impact-driven theory is presented but some evidence rule it out. A better one-Gravitational tug theory is presented to explain the moon's generation. But some proponents for impact-driven theory still point out kind of truth in it.
O: 05:21
Presents the fact that lipstick may contain health-hazardous substance except lead.
Further solidify his point by stating a researcher's experiment and describing the negative effect those substance(aluminium, cadmium..) pose on health.
However, by clarifying that the tiny metals are from machinery producing the lipsticks, the author says there is no need to abandon using lipsticks.
Finally, he pointed out color issue associated with cosmetics. Seems that he shows a neutral attitude.
感觉speed5文章结构比obstacle的更绕。。读speed文章有点太在意细节了，闪存记忆太小，继续努力。。

The lipstick for women are recently found that it is awash with and saturated with a great deal of toxic substance to human, such as mental, insects or so forth.

Then, the author takes a recent research carried by some university as an example to bolster and buttress his argument.

Moreover, the author briefly and concisely examined the definite and specific substances: namely, Al, Lead, and Mn.

What proceeding the end of the article are other damaging and detrimental composition in the lipstick, say, insects.

Finally, at the end, the history of use of lipstick is mentioned briefly by the author and contains several clear and typical historic epoch when women used the intrinsically harmful and extrinsically beautiful lipstick.

In this sense, women do sacrifice a lot to maintain their appearance.

A method to confirm the diet of dolphins
The conclusion is that the live and dead dolphins have the same diets.
But things could be more different for farther-ranging animals.

A bill passed recently.
The usage of He
A price adjustment made by American government in 1990’s

Time4 2:34
Users will increasingly depend on helium from gas fields in Qatar, Algeria and Russia. Americans attempt to reduce the helium use.

Time5 5:57
Moon rocks offer new view of lunar dynamo that generated magnetism lasted 160 million years longer that previously thought.
Two main theories explain the possible triggers for rock churning:
(1) an extraterrestrial impact
(2) heat differences
There is no consensus. Indeed, the Moon could have had different dynamos generated through different mechanisms at different times. And scientists change the investigating direction to whether the dynamo lasted beyond 3.56 billion years ago.

Obstacle 5:14
The investigation shows that several metal elements are found in lipsticks.
But there is no need to abandon the lipsticks because those elements are contaminants, rather than intended ingredients in lipsticks.

Obstacle-5：06：第一遍看总结的不够好，又看了一遍后补充了一下~~恳请赐教
Main point: there are many bad ingredients in the lipstick through time.
Attitude: neutral
Structure:
Part(1)
1.Current fact：There are many bad dangerous substances  in Lipsticks.
        The author Introduced  an experiment on lipsticks, claimed that experts found many harmful dangerous metal elements  in lipsticks
        The experts started to evaluated the risk of the lipsticks using, found that all the noxious metal elements   in it may course chilly or cancer or many other symptom.
2.Transition：However, the author said that it’s no need to abandon all the lipsticks because we can’t identify which brand of lipstick may be harmful now.
Part(2)
3.History : The author told us the history about the lipstick, many natural substances(also poisonous) were used in lipsticks by ancient people.
