Find something you care about, and you will see the difference. ②Organize a clean-up programme. People often throw litter in the place where there is already litter. This makes the community in a mess. The environment will become better if someone volunteers to help. You could pick up the rubbish with your friends once a week in your neighbourhood. You could also help take care of the plants every few days. Surely, a clean and tidy neighbourhood will be worth the work. ③Show your love to the old. Our city has some old people’s homes. Without children around them, the old people there might feel lonely once in a while. Maybe they need your help. In fact, you can do a lot for them. For example, you can talk with them or play games with them. Listening to them carefully is also a good idea. Some old people can’t see clearly and they would like you to read to them. No matter what small things you do, you can make them feel loved. ④Set up a reading project with your friends. Share your favourite books with them. Besides, you may read aloud to each other and talk about what you read. Either a book or an article can spark a lively（活跃的）discussion and your further thinking. The process often challenges more people to take action. The project is also a good way to welcome newcomers. At the same time, you may find new friends with similar hobbies. ⑤A two-month summer vacation isn’t that long, but it’s enough to make a difference. 6．How often could you pick up the rubbish according to the passage? A. Once a week. B. Every few weeks. C. Once a month. D. Every few months. 7．Why do you need to read to some old people at the old people’s homes? A. Because you can think further. B. Because you are good at reading. C. Because they can’t see clearly. D. Because they are away from their homes. 8．What does the underlined word “spark” in paragraph 4 probably mean? A. Finish. B. Start. C. Waste. D. Depend. 9．Which is the right structure of the passage? (①=paragraph 1 ②=parag raph 2 ...) A. B. C. D. 10．What is the passage mainly about? A. The people with different interests. B. The greatest time to make a difference. C. The reasons for a different summer vacation. D. The ways of making a summer vacation different. Ⅲ．用括号中所给单词的适当形式填空。 11．Amy’s brother ________ (have) the toy bear for six years. 12．Mike’s grandmother ________ (die) for about 3 years. 13．My mother ________ (see) the TV play twice. 14．Cathy and Linda ________ (not be) back to their hometown for two years. 15．Alice had lived in Singapore since she ________ (be) a child. 【参考答案】 1．【答案】A 【解析】how long“多久”，询问时间段；how much“多少”，询问不可数名词的数量或价格；how soon“多久以后”，一般对“in+一段时间”进行提问；how often“多长时间一次”，询问频率。for about ten years“大约十年”，表示一段时间，应用how long提问。因此，正确答案是A。 2．【答案】D 【解析】句意为“你戴这块手表看起来很漂亮。”“谢谢。我已经买了一个星期了。”根据for a week可知此处应用现在完成时，且谓语动词要用延续性动词。buy 属于非延续性动词，不与时间段连用，其对应的延续性动词为have。因此，正确答案是D。 3．【答案】C 【解析】由前面半句“We have been friends ...”可知本句用现在完成时；last year、one year ago和when we met last year 用于过去时态；since引导的时间状语从句用一般过去时，主句用现在完成时。因此，正确答案是C。 4．【答案】A 【解析】根据“How long have you been like this?”可知时态是现在完成时，“since+过去的时间点/一般过去时的句子”或“for+时间段”可以用于现在完成时，排除C、D。空格后面的Friday是时间点，所以应用since。因此，正确答案是A。 5．【答案】B 【解析】根据“For+一段时间”可知，此处应用现在完成时，排除C、D两项。borrow是瞬间动词，不能与“For+一段时间”连用，排除A项。keep是延续性动词，可与上述持续时间状语连用。故选B。 6．【答案】A 【解析】细节理解题。根据第二段中的“You could pick up the rubbish with your friends once a week in your neighbourhood.”可知，你可以每周一次和你的朋友一起在你的社区捡垃圾。故选A。 7．【答案】C 【解析】细节理解题。根据第三段中的“Some old people can't see clearly and they would like you to read to them.”可知，有些老人希望你读给他们听的原因是他们看不太清楚。故选C。 8．【答案】B 【解析】词义猜测题。根据第四段中的“Either a book or an article can spark a lively discussion and your further thinking.”可知，此处应指一本书或一篇文章可以“激发”讨论和进一步思考，所以画线部分spark的意思与选项B“开始”相近。故选B。 9．【答案】D 【解析】篇章结构题。分析文章内容可知，第一段引出主题；第二、三、四段给出具体的建议；第五段进行总结，所以本文的结构为“总一分一总”结构。故选D。 10．【答案】D 【解析】主旨大意题。通读全文尤其是第一段“Is the summer vacation long enough to turn life for the better? Every person has his or her own talents and interests.Find something you care about，and you will see the difference.”可知，本文主要介绍了让暑假变得有意义的三种方法。故选D。 11．【答案】has had 12．【答案】has been dead 13．【答案】has seen 14．【答案】haven’t been 15．【答案】was 学科网（北京）股份有限公司 $
