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 ewaste. Dealing with it 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 ewaste. Guiyu in Guangdong Province is one of them. This town is named as “the ewaste capital of the world”. It has to deal with 1.5 million kilograms of ewaste each year, from which it makes 75 million yuan. But it comes at a cost. Many of the poisons in ewaste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu are badly polluted.Luckily, the Chinese government wants the country to change the situation. China has passed a new environmental protection law, the strictest one we have ever had. Computer companies like Lenovo and Dell are asked to take back their old computers. Hopefully, the problem with ewaste will be solved in the near future.()16.The ewaste found in Hong Kong last month was from ________.A．France B．JapanC．Germany()17.The underlined word “buried” probably means “________” in the passage.A．焚烧B．降解C．回收()18.The town of Guiyu in Guangdong Province ________.A．is the ecapital of the worldB．has serious ewaste pollutionC．deals with ewaste safely()19.Chinese government has________.A．closed some computer companiesB．asked people to hand in their old computersC．made a new environmental protection law()20.The passage is mainly about ________.A．the ewaste problem in ChinaB．the cost of burning ewasteC．the ways to deal with ewasteⅠ.任务型阅读(共5小题；每小题4分，满分20分)阅读短文，捕捉信息，根据短文内容完成文后的句子。
The problems with the environment is becoming more and more serious. You may think it is the government's job to take action and it is difficult for the individual (个人) to protect the environment. In fact,there are several easy things that can be done to make a difference.You can start your action by learning to recycle. Although this appears really simple, there are many people who still throw glass bottles and metal cans (金属罐) into their common rubbish bins. Do you notice that our government has put many special rubbish bins in public places? They all have glass and metal recycling signs. If you spend a few seconds washing the cans and bottles and put them into the rubbish bin, you will be on the path to protect the environment.One more big waste product is newspaper. Most people will take their newspapers and throw them into rubbish bins when they finish reading them. In fact, there are many other things you can do with an old newspaper. For example, newspapers are something useful for cleaning windows. You can clean windows with newspapers rather than paper towels and window cleaners for a perfect shine.What else you can do is walking a bit more. Many people usually get into their cars and drive one block to get cola at the local shop. If you walk to the shop, you can not only spend less time, because you needn't try to find a parking place, but you will save money on oil. If you wish to save even more on oil, take the chance to share the same car with others.21．The environment is getting ________.
