Such a thing can be founded every day although it is against international laws. 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 because dangerous poison like mercury(汞) and lead (铅) can be found in them. Every time an old computer breaks down, it needs to be dealt with safely. But at present, broken computer parts are usually buried. It may be hundreds of years before they are really goes 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 “thee-waste capital of the world”. It has to deal with 1.5 million kilograms of e-waste each year, from which it makes 75 million years. But it comes at a cost. Many of the poison in e-waste find their way into the environment. Plastic is burned outdoors and chemical water is poured into rivers, Greenpeace, an environmental group, has found the air, the earth and the rivers in Guiyu badly polluted.The Chinese government wants the country to develop, but in a way that doesn’t do harm to the environment and people’s life. This year, China presents a new protection law, the strictest one we have ever had. Computer companies like Lenovo and Dell will be asked to take back their old computers. This is because the companies that make computers know best to deal with them safely. Hopefully, the problem with e-waste will be solved in the near future.( )1. The e-waste found in Hong Kong last month was from________.A. FranceB. JapanC. GermanyD. Australia( )2. The underlined word buried probably means______ in the passage.A. 焚烧B. 障碍C. 回收D. 掩埋( )3.

The passage is mainly about ________.A. the way in dealing with e-wasteB. the cost of burning e-wasteC. the e-waste problem in ChinaD. the need to pass a law against e-wasteBHow do you spent your spare time? There will be different answers to it. Most people in Poland(波兰) have their own ways of spending free time. Sometimes they just want to take a rest, but they try to do something more pleasant most of the time. They have many different hobbies, which help them to get away their everyday problems and spend their free time happily.Many Polish (波兰的) people like traveling. They always look for new places that they have never been to and add new and exciting experiences to their journey. Some of them like to climb mountains, others like to go to a sea or a lake to swim, because these can make them get exercise and are good for their health.Many Polish people also like to do sports in their free time. They are usually crazy about football, and football is regarded as the Polish national sport. Many football fans may support a certain team, so they go to watch every match of the team they support, and they buy many things that have any relation with the team. Watching sport and doing it both are good ways to relax.In addition, doctors say that doing sports is very good for health. Many people in town, especially young men, often go to the gym to attend the exercise classes to keep it.Besides these ways, Polish people have many other ways to spend their free time. And they really enjoy their free time.( ) 6.

Here are some of the findings of a survey about hopes and dreams, in which thousands of students across China took part. What are the hopes of teenagers? We received several different answers to the question: what would you like to do after you finish your education? It seems some students would like to start work as soon as they can, so that they can help offer their parents better lives. Other students hope to go on studying after they finish school and to go to university. Although money is important, many teenagers want to do jobs they like. According to the survey, the most popular choice of job is computer programming. What are the dreams of teenagers? Teenagers have all kinds of dreams. Some are more realistic (现实的) than others. For example, many students would like to be volunteers if Beijing could hold the World Cup, maybe working as translators or tour guides. And many students dream of having a trip to every corner of the world one day.According to the survey, less realistic dreams are also common, but many students reported that they were willing to work hard to achieve their dreams. Quite a few dreamed of becoming famous, perhaps famous sports people or singers. Some students would like to go on exciting trips. One student would love to sail across the Pacific Ocean. And then there are dreams that there are no possibility for students to achieve. Three students would like to be able to fly.It is clear from the survey that teenagers have similar hopes. It seems that most students hope to have a good education and find a good job. On the other hand, students dream of very different things: good things, and even crazy things. It is very important to dream, so hold on your dreams, one day they may just be realized.A survey about some Chinese students’ hopes and dreamsHopes of teenagers ●Some students want to begin work as soon as possible to help 1 their parents with better lives.●Some students hope to 2 studying after finishing school.●Many students would like to do jobs they enjoy though money is of great3 .●Most s tudents 4 computer programming as their jobs.5 of teenagers ●Some students have more realistic dreams such as working as volunteers at the World Cup and6 around the world.●Some students have less realistic dreams such as becoming fam ous sports people or singers and 7 across the Pacific Ocean.●It is highly 8 for some students to achieve their dreams such as being able to fly.Conclusion ●The survey shows that teenagers’ hopes are 9 while their dreams are different.●You can’t realize your dream 10 holding on it and hard work.1______________2______________3_______________4______________5______________6______________7______________8_______________9______________10_____________五、阅读与表达Millvina Dean, Titanic’s last survivor, died on May 31, 2009 in Southampton.

He was among more than 1,500 passengers and crew members who died in the sinking.Ms. Dean never married and spent her working life in Southampton. For many years after the sinking, she never spoke of it to people she met or worked with, partly because she remembered nothing about it and partly because she did not want to be seen as drawing attention to herself.But that changed after Sep. 1, 1985 when the wreck (残骸) of the Titanic was discovered. That set off a wave of interest in the ship, especially after the movie Titanic. “They found the wreck and after they found the wreck, they found me,” she said.In the last 20 years of her life, she went to gatherings in the USA, Canada and a number of European countries to tak e part in events related to the sinking.
