阅读快车系列答案Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.
The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.
Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.
Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.
Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.

D．air pollution |
4.According to the health and climate scientists, climate changes have been caused by ______.
|

D．storms |
5.We can infer from the passage that ______.
|
A．climate changes are having a bad effect on human’s health |
|
B．Professor Patz leads the study of climate changes |
|
C．a "heat island"effect large cities experience makes the matter worse |
|
D．rich countries are most responsible for climate changes |
Scientists at Harvard University and Bates College find female chimpanzees (黑猩猩) appear to treat sticks as dolls, carrying them around until they have children of their own. Young males engage in such behavior much less frequently.
The new work by Sonya M. Kahlenberg and Richard W. Wrangham, described this week in the journal Current Biology, provides the first evidence of a wild nonhuman species playing with dolls, as well as the first known sex difference in a wild animal’s choice of playthings.
The two researchers say their work adds to a growing body of evidence that human children are probably born with their own ideas of how they want to behave, rather than simply mirroring other girls who play with dolls and boys who play with trucks. Doll play among humans could have its origins in object—carrying by earlier apes (猿类), they say, suggesting that toy selection is probably not due entirely to socialization.
“In humans, there are obvious sex differences in children’s toy play, and these are remarkably similar across cultures,” says Kahlenberg. “While socialization by elders and peers has been the primary explanation, our work suggests that biology may also have an important role to play in activity preferences.”
In 14 years of data on chimpanzee behavior at the Kibale National Park in Uganda, Kahlenberg and Wrangham counted more than 100 examples of stickcarrying. Some young chimpanzees carried sticks into the nest to sleep with them and on one occasion built a separate nest for the stick. “We have seen juveniles occasionally carrying sticks for many years, and because they sometimes treated them rather like dolls, we wanted to know if in general this behavior tended to represent something like playing with dolls,” says Wrangham, a Professor at Harvard. “If the doll hypothesis (假设) was right, we thought that females should carry sticks more than males do, and that the chimpanzees should stop carrying sticks when they had their first child. We have now watched enough young chimpanzees to prove both points.”
1.What does a female chimpanzee do with sticks?
|
A．She gives them to her child to play with. |
|
B．She treats them as dolls. |
|
C．She makes useful tools from them. |
|
D．She treats them as weapons. |
2. What causes the different toy selection of chimpanzees, according to the passage?
|
A．Sex difference. |
B．Socialization. |
|
C．Environment. |
D．Cultural difference. |
3.We can infer from the fourth paragraph that ________.
|
A．socialization has nothing to do with human’s choice of playthings |
|
B．sex difference is the only factor in human’s choice of playthings |
|
C．the biology factor may also influence toy choice |
|
D．people choose different toys in different cultures |
4.It can be concluded from the passage that ________.
|
A．both humans and chimpanzees choose their playthings due to sex difference |
|
B．different factors cause humans and chimpanzees to choose different playthings |
|
C．only female chimpanzees have playthings |
|
D．chimpanzees usually choose playthings for their children |
