参考答案及解析

1. D错，应改为actors’或actor’s。这里句意要求使用所有格，即“演员的”表演。

2. A错，应改为What。注意what ＝ the thing（n.）＋ that，在此句中应将that改为what。

3. C错，应改为will have flown。因为飞机没有着陆，不能用过去完成时态，而应改为将来完成时态，这也是by the time... 短语所决定的。

4. B错，应改为to make。and前后表达形式应该一致，故应该将making改为（to）make。

5. D错，应将back 删掉。return本身已经包含back的意思，所以应将back去掉。

6. A错，应改为（should）investigate。虚拟语气中，意思为“建议，推荐，命令（suggest，recommend，require）”等词后面如果跟从句的话，其谓语动词应用原形动词，或加should。

7. B错，应改为should be used。因为及物动词use后面没有宾语，所以此处需要用被动语态结构。

8. D错，应改为 influential。名词应该有形容词来修饰，并且只有形容词才有最高级表达形式。

9. B错，应改为by which。注意B项后面跟的是一个名词vapor，其前面要有一个所有格修饰词才符合语法规律。

10. C错，应改为bad。一般系动词（be）和感觉动词（feel，smell）由形容词修饰。
