Then click on the corresponding button.Passage OneSome desert animals can survive the summer heat and dryness because they are very unusual. The camel, for example, can experience and bear an increase in the temperature of its body and its blood of 9°C without anything bad happening to it. In addition, it can drink a lot of water at one time; then store enough water in parts of its body to supply its needs for two weeks or more. The kangaroo rat, on the other hand, gets all the water it needs from water that it produces when it breathes. However, most animals need to maintain a fairly constant body temperature, and will die if it rises more than 5°C. Therefore, they need to find some way to stay away from the heat of the summer sun. Nor can many animals either store or produce water in their bodies, as the camel and kangaroo rat can. So they must find ways to keep their bodies from losing water because of the heat. Because very few desert animals can survive the high temperature of a typical summer’s day, most of them are active only in the night. Only after the sun has set does the desert come fully to life. The night is relatively cool, and the darkness provides protection, not only from the sun, but also from other animals and from the birds. So the coming of darkness is the signal for the large majority of animals and insects to start again their search for water and food. When morning comes, most of them seek shelter again: many go underground; nearly all find some dark and coolplace where they can keep away from the sun’s heat.For many species of insects, living in the desert is easier than for animals. Like many desert plants, they have a waterproof skin which prevents water loss because of the high temperature. In addition, some species spend all or most of their life below ground. Here, for most of the year at least, there is some moisture, and it is generally cooler than on the surface. In the case of ants, only adults leave the underground nests, and they do so only to gather food or to defend the nest against attack.pared with other desert animals, the camel can bear ______.A)a constant change in body temperatureB)a very low body temperatureC)only a little change in body temperatureD)a big increase in body temperature2.The kangaroo rat is different from other animals in that _____.A)it can drink a lot of water at a timeB)it can produce water through breathingC)it can store water in parts of its bodyD)it can maintain different body temperatures3.Why is the desert full of activity in summer nights?A)Because animals cannot sleep at night.B)Because it is cooler and safer for most animals.C)Because animals can find food in the dark.D)Because it is easy to find water at night.4.Why is it easy for many species of insects to live in the desert?A)Because they have a waterproof skin.B)Because it is not difficult for them to survive there.C)Because they are not afraid of the heat.D)Because it is not difficult for them to find food there.5.Most insects live below the ground because ______.A)it is easier to build nests thereB)it is easy for them to build nests thereC)it is easy to find water thereD)it is cooler there than in the surfacePassage TwoThe Monday edition of USA TODAY said people have died in 84 crashes since 2000more than double the number of crashes during the previous five years.Its study found that more than 10 percent of the U.S air ambulance helicopters(救护直升机)crashed during that time and about two-thirds of the fatal crashes occurred in poor visibility.After receiving hundreds of pages of documents and interviewing dozens of pilot,federal officials and executives with the companies that operate the flights,USA TODAY concluded that air ambulance companies have failed to make safety requirements that might have save lives.It also found that helicopters were used "excessively"for parents who weren't severely injured。
