新目标英语九年级过关训练

　　四、(A) 这是一篇科普性说明文，说明沙漠蔓延是人类自身的原因，人类破坏了植被造成沙化，形成沙漠。31. A。利用排除法。沙漠并非从来就无植物或动物，排除B。沙漠不可能不久就会变成良田，排除C、D。32. D。短文后四句，都讲述了green plants的重要性。33. C。从文中可知，土地沙化是人类破坏所致，与C一致。34. B。…but more and more…becoming desert…说明陆地沙化比治理快。35. A。与2题类似。

　　(B) 36. B。文章开头已经交代the United States在墨西哥的北面，Belize在南面。37. A。文章第二段交代This makes it one of the highest capital cities in the world。说明墨西哥城是世界上最高的首都。38. C。由第三段Many of the foods we eat started in Mexico.可知。39. C。由Foods like beans, maize, avocados…可知maize是一种食物。40. A。文章开头说Mexico is about one quarter the size of the United States.即墨西哥有美国的四分之一大。所以A的说法是错误的。

　　五、A：1. cutting 2. better 3. flying 4. hungry 5. having 6. repaired 7. professional 8. twentieth 9. lights 10. thinner

　　B：11. invented 12. operate 13. remained 14. produce 15. pleasant

　　六、1. used to like 2. my favorite 3. too busy to 4. didn’t pass 5. So am I 6. Neither, nor, are

　　八、本文是一篇议论文，对“锻炼和精力”这一话题展开议论，为什么睡眠充足却仍感到疲惫。其实恢复精力最好的方法是轻轻地散散步，有规律的体育锻炼会使你的疲劳永远消失。1. Read. 这是个祈使句。意思为“如果你睡眠充足却仍感到疲惫，那就读一读这篇文章吧!”2. never. 根据原文第三句“当你感到虚弱疲劳时，小睡一会儿会再糟糕不过了。”即建议人们此时千万不要小睡，因此填never。3. weaker. 由原文最后一句可知，那样的话你会觉得更加虚弱。故用weak的比较级。4. staying. 原文第二段分析了导致精力下降的两个因素，其中之一是长时间呆在一个狭小的空间里，而不起来转悠转悠。这里要用动名词作主语，故填staying。5. before. 原文中的in front of= before。6. Drinking. 原文第三段说明喝咖啡也不能使你恢复精力。用动名词作主语。7. helpful. 根据原文A cup of coffee won’t help much either…喝咖啡也不能使你恢复精力。8. on. rely on“依赖”。9. beat. 原文第三段倒数第三句说散步能够增加心率。beat一词用来表示心脏的跳动。10. few. 心率增加能够带来几个小时的精神振作。several可用a few替换。

　　九、One possible version：

　　How to learn English well

　　It is more than three years since I began to study English. At first I found it quite difficult. I couldn’t pronounce well, spell the words correctly or remember the rules of grammar. With the help of my teachers and classmates. I have made much progress. Now I am getting on well with my English. Three years’ study has taught me that one cannot learn English well without hard work. We must do more listening and speaking both in and out of class. And do more reading and writing as well. That is “Practice makes perfect”. So, in my opinion, we should work hard at English. That’s the most important thing. And we should also practice using it as much as possible.
