Time2: 3’15
The Elwha River is rich in salmon fish. A dam on the river is to be torn down, the author and the expedition team went to explore the lake bed and found something different of a century ago.
Time3:2’04
The author went back to the reservoir a year later and found the site changing. The river is coming back to life. And the explore with some biologists, he found out that the return of salmon is just a matter of time.
Time4:2’55
Meteorologists did really know much about the strong tropical cyclone Haiyan. They didn’t show much prediction before the present of the cyclone and have no idea about why it became so strong. They said that the global warming may contribute to stronger tropical cyclone.
Time5:2’29
Scientist tested volcano rocks of the inner layer of the earth by high pressure and temperature. They conclude that this layer is no more than 100 million years ago and it is important in determine the cool rate of earth and the distribution of elements.
Time6:1’29
When temperature gets higher animals get smaller
Time7:9’21

Rephrase1:
In 1917, chemists found CFC from air conditions could destroy the ozone layer and the insight got the Nobel Prize.
The danger was real, and the action is necessary.
By 1989, the US and other countries confirm the international treaties which made the ozone hole keep stable.
CFCs are also greenhouse gases. The cutting of greenhouse gases can slow the climate change and global warming.

TIME2: 02:23
The removal of dam in Washington gave the rebirth of forest in the surrounding area although salmons are gone.

TIME3: 01:43
One year later, the landscape around dam become more nature and lots of species shows there, even the salmons come back.

TIME4: 02:15
Typhoon Haiyan is the most powerful tropical cyclone.
There is no detail climate record in western Pacific cyclones, so the forecast is difficult.
The intense of Haiyan is not the signal of all intense increase of tropical cyclone.
The intense increase of tropical cyclone is partially related to global warming.

TIME5: 02:23
The interior of earth has two distinct layers, when the density increase, the high pressure will impose more oxygen which can cooler the planet.

TIME6: 01:26
Mammals shrank their size when temperature increased because of raise of carbo dioxide.

Paraphrase7: 08:14
There are two novels shows the mutation of DNA does exist which will impact our general concept of DNA.
The mutation fo DNA will disorder the DNA matching in criminal, cancer treating and so on.
Although most DNA mutations happen randomly, several organisms keep the mtDNA subsequence consistently.
The researchers can study the mutation that cause a tumor in cancer, and new finding can explain the new cause and treatment.
The mutation in mtDNA is non-random, and it can provide new working hypothesis to changing diseases.

TIME2
Before remove the Olypic dam from Elwha, the writer explore the river source, and found there was a forest which logged for a century years ago preseved under the lake bed.
TIME3
After the dam be removed. The Elwha river has changed. Water bring life again. They also found the salmon back to stream up, and they cauthed salmon measure some bio datas.
TIME4
Haiyan was the most stong, powerful tropical cyclone ever in recorded history.
Meteorologist not sure why Haiyan so strong, cause they couldn't observe it well. And Haiyan may effect by global warming or belong to Elneno phenomenon.
TIME5
By x-ray a tiny squeezing sample, new sutdy suggests that the earth's core has two layers.
TIME6
As the temperature raise, the mammal size become smaller.
OBSTACLE
Professor found part of DNA rest in body. According it, they can do research about copy(= =) org. and found which gene cause canncel etc. And as moDNA? form mother这个比较惊悚了 其实我也挺好奇智商，知识是怎么写入基因的= =random需谨慎

1'56 [190WPM] The dams in the river were removed and allow the salmons

to reappear.There are five kinds of salmon in the river, really

valuable. Fishers used to catch big salmons in the river.

1'30 [200WPM] The author saw the Elwha river come back to life and the

landscape have changed a lot. Together with the scientists from NOAA,

the author also find some adult salmon.

2'03 [165WPM] Scientists did not learn a lot from the super cyclone

Haiyan bacause instrumented aricraft does not often fly there.The

global warming might influence the typhoon and make it stronger. Less

signs of cyclone in Atlantic this year.

1'20 [230WPM] Scientists use the new  X-ray to find out that at the

beginning of the earth, the melten material are seperated into two part

with different densities. Give previous prediction a solid evidence.

1'22 [157WPM] Scientists look into the mammals in 56 million years ago

and find that when the temperature gets hotter, the mammals get smaller

in size.

6'20 [201WPM]
Main idea: DNA mutation in one body
Author's attitude: positive
Structure:
1.We always think that every peroson's DNA sequence is unique one, but

scitists find that DNA can change within one's body
2.The Scientists introduce their finds
3.The famous DNA case caused by DNA mutation
4.Scientists are now looking into how and wht DNA mutates, but they are

not research the mutation relevant to cancer.
5.The research will be helpful to determine whether the mutation will

be cancer effective.

-the Elwha river rebirths because the largest dam is almost accomplish. One years ago the author followed a biological team to to research of the river, they found many animals which live near and in the river except salmon. This year, he went with the other research team, they found 19 salmons. The author expects more and more creatures will live near Elwah river.   

time 4 2:58
-a interview of the master of meteorologist about typhoon. Master indicated that the reason is still unknown about the forming of strongest typhoon, Haiyan. Global warming has no relate to typhoon, but will forms tropical cyclone activity in the western  North Pacific and North Atlantic   

time 5 2:04
-introduces the scientists used x-ray to exam interior of earth few million year ago. The scientist found that the magma layer continued more than 100 million year, then the earth cooled down.  

time 6 1:48
-Scientists found that mammals became small due to global warming, they examined the fossil of mammal million years ago that found the same evidence. Mammal shirked 20 %, therefore, the mammals nowadays will shirking.  

time 5 2:29
the author describes the tradition of Thanksgiving, having a fest in the 2 pm, a abnormal time. People have a big meal and fail to diet.     

time 6 2:09”
-the reason of American insist having meal at 2 pm, it can trace to the medieval. People rose when the sun rise and have dinner around 2 pm which before getting dark, moreover lunch was not exist in medieval period.

time 7 6:53”   
Main idea: the study of genetic can help us to understand the forming of diseases in order to cure them .

DNA mutation change in randomly or in certain parttern.
mutation happens before born and after born period.unrelated people.the next research might be on the gene unrelated with cancer, the new research will open a new
