点拨：
1. 应选C。Scientists have always wanted…, 如果用ever只表示曾经，already 只表示已经，但选用了always 就表示不断地向宇宙进行探索。
2. 应选B。前句已经讲到知道月亮的大小远近，本句讲的是But they wanted to know more about it.
3. 应选A。送人到月球，用send men to the moon; take 是带人去，谁也没去过，谁又能带谁呢？carry men to, 装载人去，没有send to 意义好；have men to, 是错误的。
4. 应选D。reaches解释为达到only 240 kilometers; 用is逻辑上是不对的，air 不可能离开地球240公里的；用are语法上错误；空气并不travel。
5. 应选C。前句讲到A plane cannot fly, 但不知道是什么，直到下一句才点明是rocket, 所以应用something。
6. 应选D。gas 是不可数名词，用become、get、make 都不合语法；is made 表示气体在火箭内部燃烧得很热。
7. 应选A。因此推进火箭，应该用so, 这是结果；because表示因为，语义不对；for作为解释，也不行；that的表达结构不对。
8. 应选A。make the rocket fly up…, make 后面加动词原形。
9. 应选B。Rockets with men in them have been to the moon. Several rockets without men in them 应该是 have flown to another planet, 有人的火箭到月球，无人的当然已经更远。
10. 应选B。One day, 当然指的是将来，所以应该用will be able to。
V.
I’m going to be a senior school student in 2008. I want to be a volunteer for the Olympic Games. I think I can introduce Beijing to foreign athletes. So I am going to study harder from now on. I’m going to speak English and write in English as much as possible. And I’m going to learn more about the differences between Chinese and Western culture so that I can treat foreigners more politely…
