A篇
For humans, adapting to climate change will mostly be a matter of technology. More air conditioning,
better-designed houses and bigger flood defenses may help lessen the effects of a warmer world. Animals
will have to rely on changing their bodies or their behaviour. In a paper published in Trends in Ecology &
Evolution, a team led by Sara Ryding, a professor in Australia, shows that is already happening. In some
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂species of Australian parrot, for instance, beak size has increased by between 4% and 10% since 1871.
Similar trends are seen in species of mice and bats growing bigger ears, tails, legs and wings.
All that fits nicely with evolutionary theory. “Allen’s rule”, named after Joe Allen, who suggested it in
1877, holds that warm-blooded animals in hot places tend to have larger appendages than those in mild
areas. Such adaptations boost an animal’s surface area relative to its body volume, helping it to shed extra
heat. Fennec foxes, meanwhile, which are native to the Sahara desert, have strikingly large ears, especially
compared with their Arctic cousins.
Ryding’s team combined data from different species in different places. Now that they have little in
common apart from living on a warming planet, climate change is the most reasonable explanation. Since
any evolutionary adaptation comes with trade-offs, it is unclear how far the process might go. Bigger beaks
might interfere with feeding, for instance. Larger wings are heavier, and bigger legs cost more energy to
grow.
Honestly, studying a broader range of animals will help firm up exactly what is happening. For now, at
least, the increase is small, never much more than 10%. That may change as warming accelerates. But it
seems clear that the world of the future is not just going to be hotter than humans are used to. The animals
living in it will look different, too.
22. What does the author want to tell us by mentioning Australian parrot in Paragraph 1?
A. Climate change is affecting animals.
B. Scientists are doing research on animals.
C. Humans can adapt to climate change more easily.
D. Animals are adapting to warmer climate in their own ways.
23. What is the benefit of having bigger body parts according to the passage?
A. Getting rid of additional heat.
B. Becoming larger and stronger.
C. Enlarging animals’ surface area.
D. Becoming more sensitive to the environment.
24. What do we know about the change in animals from the last two paragraphs?
A. It comes at an expense. B. Its cause is definite.
C. It happens in the same habitat. D. Its process will end soon.
25. What can be a suitable tile for the text?
A. Living on a Warming Planet B. Evolution to Survive Heat

B篇
A set of tusks (象牙) is usually an advantage for elephants, allowing them to dig for water, peel bark for
food and defend themselves. But during episodes of intense ivory poaching, those big tusks may invite
danger. Now researchers have figured out how years of civil war and poaching in Mozambique have led to
a greater number of elephants that will never develop tusks.
During the conflict from 1977 to 1992, fighters on both sides killed elephants for ivory to finance war
efforts. In the region, around 90% of the elephants were killed. The survivors were likely to share a key
characteristic: half the females were naturally tuskless - they simply never developed tusks - while before
the war, less than a fifth lacked tusks.
After the war, those tuskless surviving females passed on their genes with expected,as well as
surprising, results. About half their daughters were tuskless. More confusing, two-thirds of their offspring
(后代) were female. “The years of unrest changed the evolution in that population,” said evolutionary
biologist Shane Staton.
Most people think of evolution as something that proceeds slowly, but humans can hit the accelerator.
“When we think about natural selection,we think about it happening over hundreds, or thousands of years,”
said Samuel Wasser, a conservation biologist at the University of Washington. “The fact that this dramatic
selection for tusklessness happened over 15 years is one of the most astonishing findings.”
Now the scientists are studying what more tuskless elephants means for the species and its
environment. “If an elephant doesn’t have the tool to peel bark from trees, then what chain reaction will
happen?”
26. What have researchers found out according to paragraph 1?
A. The function of tusks. B. The influence of civil war.
C. The fight against ivory poaching. D. Reasons for naturally tuskless elephants.
27. What do paragraph 2 and 3 tell us about the elephants?
A. Their pricey tusks. B. Their evolution process.
C. Their endangered conditions. D. Their sufferings during the war.
28. What surprised Samuel about the findings?
A. The rapid speed of evolution. B. Elephants’ gender imbalance.
更多资料添加微信号：hiknow_007 淘宝搜索店铺：乐知课堂C. Elephants’ population reduction. D. The diversity of natural selection.
29. Which might be one of the results of the chain reaction?
A. Elephants will die out soon. B. Elephants will shift their diet.
C. Elephants will suffer from starvation. D. Elephants will be replaced by other species.
