Module 4课时达标训练(十六)Ⅰ.阅读理解More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study. By then, scientists say，global warming will have melted 42 percent of the Arctic sea ice. By 2100, only a very few of these important creatures will be left.The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne, who has been asked to put polar bears on the US endangered species list.Polar bears depend on floating sea ice as a platform for hunting seals, which are their main food. Without enough ice, polar bears would be forced to go onto the land, where they are poorly skilled hunters, and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.The team of American and Canadian scientists spent six months studying bears，on the ground，from spotter planes and in the lab, using computer models.Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have shown that the ice has decreased to an all-time low.However, not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear-hunting trips.1．What do we know about Dirk Kempthorne according to the passage?A．He is an animal scientist.B．He is a protector of animals working for the US government.C．He was asked to put polar bears on the US endangered species list.D．He offered to put polar bears on the endangered species list.2．Why will polar bears die out if there is not enough sea ice?A．Because polar bears can't catch enough food without ice.B．Because polar bears eat ice when they feel thirsty.C．Because polar bears will be easily found by hunters without ice.D．Because most female bears are used to giving birth under ice.3．After a sixmonth study, some scientists fear that ________．A．there is something wrong with their computersB．polar bears will disappear even faster than they ever expectedC．their computer models are not as accurate as they expectedD．global warming will destroy everything in the Arctic4．What does the writer want to tell us in the last paragraph?A．The forecast about the future of polar bears is not correct.B．Global warming won't have any effect on hunting trips in the Arctic.C．Polar bears are an endangered species as a result of bearhunting.D．People don't pay enough attention to the protection of endangered species.Ⅱ.任务型阅读Americans use many expressions with the word “dog”. People in the United States love their dogs and treat them well. 1.________However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog's life, describes a person who has an unhappy existence.Some people say we live in a dogeatdog world. 2.________They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog tired. And, the situation would be even worse if they became sick as a dog.3．________This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.4．________People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard.5.________A．We do not want it to rain cats and dogs.B．Still, people say every dog has its day.C．That means many people are competing for the same things, like good jobs.D．Dogs are their best friends and they are loyal to people.E．There are many other expressions waiting for you to explore.F．Some people are compared to dogs in bad ways.G．They take their dogs for walks, let them play outside and give them good food and medical care.Ⅲ.完形填空Recently, I flew to Las Vegas to attend a meeting.
