the most common trees in Amazon. Most species are extremely rare.
2. 2'16''
the meteor that struck Earth has a companion of satellites, which could help to trace the object's orbit.
3. 1'56''
companies are fascinated in producing genetically modified crops.
4. 2'15''
the genetically modified crops have difficulty in winning the approval of the public.
5. 2'32''
why people understand the information of GM products wrongly.
GM is by no means worth development as it could achieve many aims.
have the upper hand,占上风，优势
6. Obstacle: 7'36''
scientists suggest changes in the design of ITER.
One change is to replace carbon divertor with Tungsten.
the existing plans use carbon but could absorbs tritium.
Tungsten is tested and used to address the problem. though tungsten is difficult, it has advantages over carbon.
The other change is to add a second set of coils.

TIME2: 00:59
Amazon has the most diversity plant species which even common there.

TIME3: 01:33
The threat from one object’s orbital comparison is slight.

TIME4: 01:11
The genetically modified crops were first introduced about 30 years ago, and in 1985, more and more companies were interested in GM crops.

TIME5: 02:02
When GM crops become popular, there are lots of concerns from people about these unfamiliar things although the yields and productivity have been expanded a lot.

TIME6: 01:51
There are lots of misinformation in public about GM crops, and the genetically transform technology did increase the output while decrease the plant areas.

Paraphase7: 06:51
ITER is the international collaborate nuclear fusion in France.
Researchers find several plans to solve the superhot problem of ITER. The material of divertor used in ITER is the key point.
The carbon divertor will make the elements very active during superhot temperature.
So, researchers change plan to use tungsten which melting point is more than 3000°C.
Although the tungsten divertor seems quite safe, the process of change the operation system is complex and there is still unstable radioactivity in the vessel.

-If your smart phone is stolen, you should shutdown it, otherwise the thief might use your personal information.  

time2  2:21”
There are variety of trees in Amazon rain forest. Some of them are grown naturally, others are grown when European arrive there. Even the botanists are still many unknown specific species there. The author afriad that they might extinct before discovering.     
                  
time 3  1:42”
-a new study mentions a meteor through the sky in Russia. The new technology enable scientists to determine the orbit.  


time 4 1:45”
-30 years ago scientists published the gene  modification technology; this month scientist say that they can insert foreign genes into plant cells, people can take advantage of it such as easy growing, more desirable.

time 5 1:57”
The history of genetic modified corps. The sales reached the peak at beginning, afterward are felled down. Once they used to popular, but now many people are afriad unknown  aftereffect about intaking genetic modified products. USA is the biggest country to enjoy GM food, the GM food must be strick labeled.

time 6 ”
People can reach the information of GM food though internet, unfortunately, most information are wrong. These wrong information influence a lot of person even their children. Supporting GM food is also supporting development of genetic science. There are still a lot of benefit of GM food.

   There are approximately 16,000 species of trees in the Amazon. Euterpe precatoria has been estimated the most common species of the Amazon.
time3 -- 2'05
   A meter's streak can pin down the object's orbit.Scientists analyse the data coming from satellites to determine an object's orbit.
time4 -- 1'20
   GM food made a big progress and promised to make life easier and fullfil the desire.
time5 -- 2'17
   GM crops got into a market crisis afer their birth.However, the biology industry began to pay more attention on increasing farm yields.Although it make sense, there still remains public-relations problem.
time6 -- 2'06
  People debated about the GM technologies. Transgnetic tecnique is still indispensible

Obstacle -- 8'29
==>the several key changes of ITER could increase technical risk.
==>It's difficult to reach more than 150 million°C. Tokamak is calling to built to solve the problem

new reactor will take off risk, but still need approve.base in france, the reactor took example of unlcear explorion in the sun. the way to make moe efficent and economic process development. carbon devorter, melt stuff.
