Speed
2’01’’ The passage introduces a chemical that repells insects, here mentions mosquitoes. And an experiment found that mosquitoes could be resistant to the chemical within 3 hours. The detailed process is introduced.
2’32’’ Another experiment was done to illustrate that it is mosquitoes are really resistant to DEET. And the reason is not the mutation but the adaptation. Since the adaptation is not genetic and only a small part of mosquitoes are resistant to DEET, so it is still widely used. Besides, no other chemical found.
1’20’’ Some people are more likely to attract mosquitoes because of their blood type and their ability to secret a special chemical.
1’52’’ Here mentions some other possible elements that may attract mosquitoes. Bacterium, CO2, beer(may not be the reason because it relates to metabolism) and metabolism.
1’14’’ Another 4 possible reasons that may affect the mosquitoes’ preference.

Obstacle
（忘了计时了……）
Some scientists think that it is the attractive chemical that appeal mosquitoes while some scientists believe that it is the repellents people secrete repell mosquitoes or cover the smell that appeal mosquitoes. Experiments have been done to find the odor that could be effective repellent and be put into market. However the real cause is still unknow.
Structure:  different pinions>>experiments>> no conclusion

3’11’’(肿么读的这么快？！)
What is procrastination and its two parts. The author mainly talks about the second part and teach us how to overcome it: make small steps toward the goal. Then examples to illustrate the method.

作业是完成了，可是有木有修改意见或者好的参考咧？？

main idea: Studies have shown that some special chemicals may repel mosquitoes.
structure:
-Researchers thought that some people appear to be less attractive to mosquitoes because they have special chemicals.
-Researchers made a research and got these chemicals.
-They are trying to make them into better repellents and to sell them on the market.
-There are other researches on the reason why some people are less attractive to mosquitoes.

1>research found immune to the chemical
2>deef--M runs contrary to previous understanding
3>experiment-->tow group/more attempt to do still less than 70-80%

02'54
1>further proof/not chance to habit-->lower try to reach deet
2>sort out the interaction between chemicals and human skin/was not deef responsibility
3>why--antennae get used to
4>D not only but also...stop spread
5>adult/offspring not
6>no other repellent

why prefer-->blood type/secret

DEEF is a main insect r...in the market.
whether M is immune to DEEF when they espure in DEEF after hours?
there are a experiment to idetify M's behaviour when expours to DEEF
many M 吸血成功 when they land in skin second time.however,the percent of 吸人血的M still less than the percent of not expoure in DEEF.

2'17'8
another experiment to show that M adapt to DEEF
the reason M immune to DEEFne is genetic transtion,the other is ....
however,DEEF is still useful,since adult M only live a few days;therefore,the rate M which immune to DEEF can transate the genetic to offshore is low.
we still use DEEF also because M usually transate diseases.

1'17
why M bite some people more often than others?
reason1:blood type O B A

2'09'4
reason2:carbon doxide.the more exhabit,the more likely for M to bite
reason3:acid ,exercise.through sweat,higher skin temperature,the more likely for M to bite
reason4:beer.
reason5:....

1'17
reason6:pregant.pregnent women enhale more carbon dioxide and have higher temperature
reason7:nature P.unknow
reason8:genetic reason.unknow
reason9:cloth color.red,dark blue and black more likely for M to find.

5'18'8
why M prefer some people to the others?---odds
experiment to find which odds attract to M.two group of people.
scientists want to make R to M from those odds M donnot like.
introduce other research.

TIME1：1min35s
When the mosquito which is exposed to DEET for a time, it will immune to this chemical .This phenomenon different from scientists previous thought. So they did some researches.
TIME2:1min51s
Why the mosquito can immune to the DEET? However, scientists said people have to keep use DEET for some reasons.
Time3:1min20s
The mosquito prefer o type of blood and the b type of blood is the second choice for the mosquito. The skin of people can secrete some chemical to shows which type of the blood .
Time 4:1min30s
CO2,bacteria,drinking will affect the mosquito’s choice.
Time5:1min19s
Pregnant, cloth color ,genetic repellants can decide whether the mosquito choose this kind of people to bite.
Time6:6min12s
The researchers took some trials to find whether the mosquito bite some people rather than other people and what the odors compounded by the people the mosquito prefers. Also, the researchers  point  out some diseases spread by the mosquito .Finally, the researchers identify whether the repellants work well to avoid mosquito and how can make them work well.
Time7:2min57s
how to overcome the procrastination ?Maybe use the imagination process can help people who has this problem.
