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．燃烧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 e­wasteⅢ.任务型阅读(共5小题；每题4分，总分值20分)阅读短文，捕捉信息，根据短文内容完成文后的句子。

Section A ,3a拯救鲨鱼很多人都听说过鱼翅羹。

这道昂贵又著名的菜在中国南方特别流行。

但是每次当你喝鱼翅羹的时候，你是否意识到你杀了一整只鲨鱼？当人们捕捉到鲨鱼的时候，他们切掉鲨鱼的鱼鳍，然后把它们扔回大海。

失去鱼鳍的鲨鱼再也不能再水里游，会慢慢死去。

这种做法不仅残忍，而且对环境有害。

鲨鱼处于海洋生态系统食物链的顶端，如果他们的数量下降得太多，将会给所有的海洋生物带来危害。

很多人认为鲨鱼永远不会濒临灭绝，因为他们是食物链的最强者。

但事实上，每年有七百万的鲨鱼被捕杀和交易。

在过去的20年到30年，某些品种的鲨鱼数量下降了超过90%。

世界各地的环保组织，如野生救援协会和世界自然基金会，都在向公众宣讲“猎翅的（残忍）行为。

他们甚至已经呼吁政府立法停止鱼翅的销售。

到目前为止，没有任何科学研究表明，鱼翅对健康有好处，那么为什么要吃他们呢？帮助拯救鲨鱼吧！Section B , 2a重新思考重新使用，重新利用你经常扔掉你不在使用的东西吗？你是否曾想过这些东西还能很好地重新利用？如果你有一个充满创意的头脑，没有东西是废品。

你可能从来没听说过艾米.海斯，但她是一个非常不寻常的女性。
