Last month Hong Kong officers found 131,000 kilograms of broken computers, TVs and phones sent from Japan.Things like these are called electronic waste, or e-waste. Dealing with them is not an easy job. Every time an old computer breaks down, it needs to be dealt with safely. What is worse, at present, broken computer parts are usually buried. It may be hundreds of years before they are really gone in the earth. Many places in China are polluted by e-waste. Guiyu in Guangdong Province is one of them. This town is named as “the e-waste capital of the world”. It has to deal with 1.5 million kilograms of e-waste each year. Many of the poisons(毒物)in e-waste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu badly polluted.Luckily, the Chinese government wants the country to change the situation. This year, China passed a new environmental protection law. Computer companies like Lenovo and Dell will be asked to take back their old computers. Hopefully, the problem with e-waste will be solved in the near future.26.The e-waste found in Hong Kong last month was from .A.FranceB.JapanC.Germany27.The underlined word “buried” probably means in the passage.A.焚烧B.回收C.掩埋28.The town of Guiyu in Guangdong Province .A.is the e-capital of the worldB.has serious e-waste pollutionC.spends much money on e-waste29.This year, the Chinese government .A.closed some computer companiesB.asked people to hand in their old computersC.made a new environmental protection law30.The passage is mainly about .A.the e-waste problem in ChinaB.the cost of burning e-wasteC.the ways to deal with e-wasteBI think it is safe to say that snakes are not popular among most people.It would be hard to find a person who is neutral(中立的),or simply doesn't care one way or the other.What I wonder is why something even without legs causes such great fear.Snakes are quite useful,but that doesn't seem to matter.Snakes help control the population of mice.Without snakes,perhaps we would find mice everywhere.Most ofus,however,would rather see a mouse than a snake.The poison argument(毒性的争论)is a strong one.Some snakes are poisonous,and this causes people's death.However,the poisonous snakes are only a small number.We can't say all the snakes are bad just because of a few dangerous ones.And what do we do with the people who really like snakes? They like snakes even more strongly than we dislike them.These people learn about them,find them out,and watch them carefully.Why? The only reason I can think of is that these people are open-minded.They are able to put aside differences and welcome the snake as a friend.Whatever the reason for our like or dislike,snakes do something good in the circle of life.They would prefer to be left alone,and that is what we should do.If you're lucky,you might not run across more than a few of them in a lifetime.That would be fine with most of us.31.How does the writer describe the appearance of snakes?A.Something even without legs.B.Something not popular among people.C.A person who is neutral.D.A person who cares about nothing.32.Which of the following shows that most people dislike snakes?A.They welcome snakes as their best friends.B.They would rather see a mouse than a snake.C.They wonder why snakes can cause great fear.D.They learn about snakes and watch them carefully.33.Although some snakes are poisonous, .A.they cause many people's deathB.they control the population of miceC.they are not dangerous to peopleD.they are only a small number34.People who really like snakes are open-minded because they .A.are able to put aside differencesB.think all the snakes are poisonousC.are able to deal with poisonous snakesD.take part in the poison argument35.The last paragraph seems to tell us that the writer .A.dislikes snakesB.has the best luckC.loves snakesD.prefers to be left aloneC“Save the whales!” That's what the picture on Jake Smith's bedroom wall said. Jake liked having a picture that said something important that showed he cared. He just never expected to get a chance to save a real whale, one right in his own neighbourhood.It was a Saturday morning when the newspaper first reported the whales' coming. A group of the animals were swimming close to the beach in Jake's hometown. All the local people rushed out to the beach to see them. They were expecting a beautiful show, better than a movie, but nothing they'd have to do anything about.Then one whale swam in the direction, directly towards land. It came in with the waves, and when the waves receded, it stayed. Its huge body rested on the sand. Suddenly, Jake and his family and all the others were no longer sightseers. They had to become rescuers. A few people ran towards the animal. They pushed and tried to force the whale back into the water, but it was no use.An animal rescue service team soon arrived in a truck with heavy lifting machinery, to help move the animal. Jake and his family couldn't do much on the beach, so they went back to their house and made sandwiches and hot tea for the rescuers. At least, Jake thought, they could help in some way.Back at the beach, they offered the food to the rescuers and were happy to see that it was needed. It was getting dark. Some people lined up their cars along the beach and shined the headlights on the sand. The rescuers would not give up. After trying many times they were finally able to lift the whale into the water. Everyone cheered when it headed out tosea. It swam out about a mile and then disappeared for a moment under the sea. Then, in what looked like a jump for joy, it rose high above the water—a thank-you to those who had worked so hard to save its life.36.What does the picture on Jake's wall tell us about him?A.He lived near the ocean.B.He cared about the environment.C.He worked as an animal rescuer.D.He thought whales were the most beautiful animals.37.Why did the local people go down to the beach that morning?A.To swim with the whales.B.To help rescue the whales.C.To see the whales swimming.D.To watch a movie about whales.38.The underlined word “receded” in Paragraph 3 means .A.didn't moveB.went back outC.washed overD.got up39.How did Jake and his family help save the whale?A.By calling the rescue service.B.By asking their neighbours for help.C.By giving the rescuers food and drink.D.By controlling the people on the beach.40.In what order did the events of the whale rescue take place?a.The whale disappeared under the sea.b.People turned on the lights of their cars.c.Rescuers lifted the whale into the water.d.Animal rescue service brought its truck.e.People pushed the whale towards the sea.A.e-d-b-c-aB.e-b-c-d-aC.d-b-e-a-cD.a-e-b-d-c阅读短文,根据短文内容,从短文后的五个选项中选出能填入空白处的最佳选项。
