(谢谢Christine，今天的速度真的很赞，很有意思。看来长得高的女生不仅找男朋友悲剧，baby也不能有很多。唉……)


越障：6’32（看完文章查了一下才知道原来Hydra是九头蛇的意思…………= =！）
Main Idea:
The passage explore the mystery to keep hydra immortal and make people old.
Structure:
*about hydra: since hydra is immortal, it is often used in experience.
*The stem cells cease to regenerate is the key factor of aging in humans.
*FoxO, the longevity gene, is discovered in the Hydra that might play role in aging.
*the mechanism of hydra running FoxO was revealed.
*FoxO makes human life longer, and the influence from the environment must be explored.
*the maintenance of stem cells and the maintenance of a functioning immune system are two main elements that will influence the human's life span.
(今天的越障思路挺清晰的，果然有小标题就是不一样。)

我来交作业！第一次参加阅读小分队，速度照大家比还是有些慢，我会好好练习的！感谢Christine！

Scientists have found that even the lowest level of radiation is harmful to life. And natural backgrounds are the factors to affect the radiation.  Geographic locations with natural background radiation that greatly exceeds normal amounts.
2'09
Scientists showed that the frequencies of bad effects happen more than random chance. And we just consistently overlook the negative effect of the radiation. We should pay more attention to the level of the radiation, and adjust the regulations.

Men and Women conflicted about the ideal height. This phenomenon is because men and women are different, some genes benifits for the men, but can be a obstacle for the women. Genetic Selection attributes to the roproductive success.
1'50
Shorter women have a tendency to have more children, and younger mothers have a tendency to be shorter. We can see whether one's sibling has more or fewer children through the height. In additon, this research comes from a large database. We are not informed the reason why shorter women have more children.

Global warming cause the ice of Greenland to melt. It is pretty difficult to see how greenhouse gas affect different regions on earth. Scientists have set a model to learn the change of Greenland under global warming through microscope. And the Greenland ice sheet will lose more ice to melt under either circumustance. The results may be conservative because it overlooks the progressive aspects of the overall rising temperatures. The gas will results in the change of ocean sanity and ice sheet of nearby islands.

Obstacles(5'20)太慢了。。。
Main idea：the author has discussed the relationship between immotal Hydra and human aging.
Structure:
1、Scientists are studying the reason why Hydras are immotal and surpringly find the links to the human longevity genes.
2、Hydras have stem cells that are capable of proliferating,and stem cells are important for humans to delay the aging process.
3、FoxO genes are essential factors to Hydra. One scientists have claimed that these genes are also important to human beings, but it is not verified.
4、It is still a great progress to find out the concluison: FoxO genes are decisive to stem cells;aging process depends on two factors: stem cells and immune systems.
Author's attitude: agree

Scientists tested large number of people in the global areas where radiation comes from minerals under grounds——>even small radiation can lead to damage.
2.[313]2’03
Scientists reported negative effects of radiation and there are no threshold-effect measurable.
3.[266] 2’10
Men and women with different height may influence their offspring’s height. Short women and men of average height may have more children.
4.[288]1’55
** sexual conflict: a trait is advantageous when it presents in one sex, while its disadvantageous when it presents in the other sex. But it’s still unclear that why short women may reproduce more children.
5.[417]2’40
Scientists applied two models to predict that the ice in Greenland will melt quickly and its shape will change as a result of warmer temperature.
Obstacle:[697]4’30
Main Idea: Describe the relationship between Hydra immortal and human longevity
Author's attitude: neutral
Article structure:
1-2) Hydra has no signs of immortal, but stem cells play an important role on its immortal. & Human aging is also related to stem cells.
3-5) FoxO gene was discovered in animals and humans. It is important for aging. & FoxO’s active or inactive behavior will influence Hydra. & FoxO can also make people live longer.
6) Two conclusions: FoxO influence stem cells, then influence human’s life span. & longevity was determined by two factors: stem cells and functioning immune system.
