1、单元检测卷：Unit 4阅读下列短文，从每题所给的（A、B、C、D）中，选出最佳选项ACalifornia Condors Shocking RecoveryCalifornia condors are North Americas largest birds, with wind-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training and medical trea

2、tment are helping to rescue these big birds. In the late 1980s, the last few condors were taken from the wild to be bred(繁殖) . Since 1992,there have been multiple reintroductions to the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico. Electric

3、al lines have been killing them off. “As they go in to rest for the night, they just dont see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once. So scientists have come up with a shockin

4、g idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%. Lead poisonous has proved more

5、difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles

6、 Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011. Rideouts team thinks that the California condors average survival tim

7、e in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them. ”1.California condors attract researchers interest because they .A.are active at nigh

But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as wel

11、l as during the day, British-based researchers say. David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds biological clocks, leading to them being wide awake when they should be asleep. Dr Dominoni, who is putting cameras inside nes

12、ting boxes to track sleeping patterns, said lack of sleep could put the birds health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at

13、night. He told people at a conference, There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy.

14、And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, In Glasgow where I live, gulls are a serious problem. I have people coming to me saying You are the bird expert. Can you help us kill these gulls?.During

15、the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people cant sleep. Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud nois

16、e. However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.5.According to Dr D ominonis study, what ca

17、use robins to sing so much? A. The breeding season. B. The light in modern lifeC. The dangerous environment. D. The noise from heavy machinery.6.What is the researchers concern over the increase of birds song output? A. The environment might be polluted. B. The birds health might be damaged. C. The

18、industry cost might be increased. D. The peoples hearing might be affected.7.What does the underlined word nocturnal in Paragraph 5 mean? A. Active at night. B. Inactive at night. C. Active during the day. D. Inactive during the day. CDue to climate change, Arctic ice is breaking up earlier in the s

19、pring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay. Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to s

20、pend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In th

21、e past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed. In Hud

22、son Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of

23、the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.8.What is Arctic ice doing earlier each year?AIts free

40、rest like the forests we now find in Malaysia and Thailand. As more and more _21_ came to live in Hong Kong, these trees were cut down and burnt. Now there is no forest left, _22_ there are still some areas covered with trees. We call these _23_. Elephants, tigers, monkeys and many other animals use

41、d to live in the _24_ forests of Hong Kong, and there were even crocodiles in the _25_ and along the coast. When people came to live in Hong Kong, the animals began to _26_ out. Early farmers grew rice and kept pigs and chickens in the valleys. They _27_ the trees and burnt them. They needed fires t

42、o keep themselves _28_ in the winter, to cook their food, and to keep away from dangerous animals. Elephants quickly disappeared because there was not enough _29_ for them. So did most of the wolves, and tigers. Monkeys, squirrels and many other animals soon died out in the same _30_. You might thin

But there is _34_ a good deal of countryside in Hong Kong and New Territories, and there are still about thirty-six different kinds

44、 of animals living there. One of the most interesting _35_ is the barking deer. They are beautiful little creatures with rich, brown coat and a white patch under the tail. They look like deer but they are much _36_. They are less than two feet high. The male barking deer has two small horns but the

45、female has none. They make a _37_ rather like a dog barking. Barking deer live in thick shrub（灌木） country and are very good at _38_. They eat grass and shrubs, mainly in the very early morning and late afternoon and evening. This is when you are most likely to see one but you will need to be very qu

46、iet and to have very _39_eyes. In Hong Kong the barking deer has only one _40_ - man. Although it is illegal, people hunt and trap these harmless little animals. As a result there are now not many left. There are a few on Hong Kong Island but none in the New Territories.21:ApeopleBchildrenCladiesDwo

49、ent. But wildlife today disappears or is in danger just because humans do harm to it. For example, tigers 41 （hunt） for fur to make carpets so that they can only live in secure reserves; grassland is destroyed without mercy so that dust storms come into being, 42 (affect) distant cities. Last year,

50、scientists saw some monkeys 43 (rub) themselves with 44 certain kind of insects to protect themselves from fierce mosquitoes biting. According to the result of the 45 (inspect), they found that the insect contains a 46 (power) drug, so local farmers were employed to catch the insects. The ending was

51、 47 the insects disappeared from the whole zone. When told that it was 48 loss to humans, the farmers burst into 49 (laugh) and responded, “Our real loss is our decreasing income.” We should appreciate the natural balance and pay more attention to the 50 (important) of wildlife protection. Not until

52、 we succeed in letting wildlife live in peace, can we smile in relief and live a peaceful life.短文改错 When I was a child, I hoped to live in the city. I think I would be happy there.
