（一 ）A boy quarreled with his parents and ran away from home. He had a hard life 1 any contact with his family for years. Later he wanted to go home 2 he was afraid that his parents might not welcome him. Finally he decided 3 （send）a letter to his father expressing his desire to return home and begging his pardon. In his letter he asked his father to tie a white ribbon on 4 tree near his house by the side of the railway lines if he was ready to welcome him back home. 5 he did not see the ribbon on the tree, he would think that his family did not welcome him and then he would leave them forever. He boarded the train and waited very 6 (nervous) as the train was about to pass by his home. To his surprise, the tree 7 (decorate) with hundreds of white ribbons 8 danced in the wind. His family did not want him to miss the sight of the ribbon and the welcome signal, so 9 covered the whole tree with ribbons to show their whole-hearted 10 (happy) and willingness to welcome him back. (二)With the 1 (develop) of industry, air pollution is getting more and more serious. In Beijing, many people suffer different kinds of illnesses because 2 air pollution.Air pollution is caused by the 3 (follow) reasons: about half of the problem is caused by vehicles. There are more and more cars, buses on the roads, and they give off 4 (poison) gases. 25% of air pollution is caused by factories. Another factor is the smokers. Smoking not only does harm to their health 5 to others. 6_ these, about 10% of air pollution is caused by other reasons. We should take some measures 7 (fight ) pollution. New fuel can be used to take 8_ place of gas. We can plant more trees. If everybody realizes the 9_ (important) of environment and does something to stop pollution, the problem will 10_ (solve). (三)People in communities have slowly been pushed apart through the years, mostly because people 1 (simple) arent taking the time to say a simple “hello”. After considering this phenomenon, I decided I was going to change the way I got on to others. My opportunity came one morning when I was in the community library. I passed by a girl 2 dropped her books out of her locker. 3 (think) that someone else would help her pick them up, I continued 4 way. However, when I had to go back 5 I forgot my book, I noticed she had just finished picking them up by herself. No one had stopped 6 (help) her. “OK,” I thought to myself, “this is where I should have changed.” My best opportunity came a few days later when I saw a man sitting by himself waiting for the library to open, so I sat down next to him and 7 (begin) a conversation. 8 was difficult to get started ,and even when I had to say goodbye, almost every response from my new friend had a tone (语气) of doubt in it .And who could blame him?People arent used to making 9 unprepared chat with a stranger. But a change, no matter how desperately it is needed, doesnt just happen. It takes people like us to make it possible. I advise you to take a small step out of your comfort zone and try to make someones day much 10 (bright) .Together, we can really make our society come closer as a whole.(四)The Internet has become part of young peoples life. A report 1 (show) that 38% of students often use the Internet . Most of them get 2 (use) information on the Internet 3 use the internet to help in their studies. But many students dont use it 4 a good way. Some play games too much, some visit websites 5 shouldnt look at. So bad things may happen 6 _ students spend too much time on the Internet. 7 is important for students to use the Internet 8 (proper). Now we have a textbook, which uses many examples 9 (teach) students some good ways to use the Internet. It gives useful advice. Some students also make friends on the Internet. But if you want to have a face-to-face _10_ (meet) with your online friends, let your parents know and meet in a proper place. (五)It is commonly believed that school is where people go to get education. However, it has been 1 (say) that today children interrupt their education to go to school. The difference 2 schooling and education suggested by this is important.Education is endless, 3 (compare) with schooling. It can take place anywhere. It includes both the standard learning that takes place in schools and 4_ whole universe of learning out of class. Though the experience of schooling can be known in advance, education quite often produces 5 (surprise). A chance talk with a 6 (foreign) may lead a person to discovering how little he knows of another country. People obtain education from babies on. Education, then, is a very broad and 7 (limit) term. It is lifelong experience that starts long before the start
