If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid. After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in a variety of ways．A frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days, then, allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．

A．Further explanations as to why tree frogs hatch ahead of schedule．
B．How the unborn frogs know when a snake is about to attack them．

If you are a male and you are reading this ,congratulations: you are a survivor .According to statistics, you are more than twice as likely to die of skin cancer than a woman ,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you will die on average five years before a woman.
There are many reasons for this-typically, men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.
“Men aren’t seeing doctors as often as they should, ” says Dr. Gullotta, “This is particularly so for the over-40s,when diseases tend to strike.” According to a recent survey, 95%of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group.
“A lot of men think they are invincible （不可战胜的）,”Gullotta says. “They only come in when a friend drops dead on the golf course and they think, Geez, if it could happen to him……”
Then there is the ostrich(鸵鸟) approach, “ Some men are scared of what might be there and would rather not know, ” says Dr. Ross Cartmill.
“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says .He believes most diseases that commonly affect men could be addressed by preventive check-ups. “Prevention is cheaper in the long run than having to treat the diseases. Besides, the final cost is far greater, it is called premature death.”

D. Men aren’t as cautions as women in face of danger.
3.Which of the following best completes the sentence “Geez, if it could happen to him,…’?
A. it could happen to me, too
B. it would be a big misfortune.
C. I should avoid playing golf.
D. I should consider myself lucky.
4.What does Dr. Ross Cartmill mean by “the ostrich approach”(in para.5)

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean."
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."
1.What can be the best title of the passage?
A．Sea Life Facing Danger B．Climate Change Affecting Seawater
C．Oceans Becoming More Acidic D．Scientist Researching Seawater
2.Which of the following shows the process of the impact of atmospheric CO2 on sea life?

D. e → d -→ c → b → a

B．a major cause of climate change
C．some former theory
D．the expectation of other scientists
4.What does the passage want to tell us most?

People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior.
However, the study also found that when less-educated people did suffer stress it was more severe and had a stronger effect on their health.
From this, researchers have concluded that the day-to-day factors that cause stress are regular. Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.
The research team interviewed a national sample of 1, 031 adults daily for eight days about their stress level and health. People without a high school diploma reported stress on 30 percent of the study days, people with a high school degree reported stress 38 percent of the time, and people with college degrees reported stress 44 percent of the time.
“Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health.” leading researcher, Dr. Joseph Grzywacz of Wake Forest University Baptist Medical Center, said in a prepared statement. “The downward turns in health were connected with daily stressors (紧张刺激物), and the effect of daily stressors on their health is much more damaging for the less advantaged. ”
“If something happens every day, maybe it’s not seen as a stressor.” Grzywacz says. “Maybe it is just life.”
1.Stress level is closely related to ___ .
A. family size B. work experience
C. body weight D. social position
2.Which group reported the biggest number of stressful days?
A. People without any education. B. People without high school degrees.
C. People with high school degrees. D. People with college degrees.
3.The less advantaged people are, the greater .
A. the effect of stress on their health is B. the degree of their health concern is
C. the level of their education is D. the effect of education on their health is
4.Less-educated people report fewer days of stress possibly because .
A. they don’t want to tell truth B. they don’t want to face the truth
C. stress is too common a factor in their life D. their stress is much greater
