Unit 24 What were they doing?

典型例题

　　病句诊所

　　1．刘明发现学好英语很困难。

　　误：Liu Ming found very difficult to learn English well.

　　正：Liu Ming found it very difficult to learn English well.

　　析：这句话的宾语为to learn English well，very difficult 在句中作宾语的补足语，为了使句子前后保持平衡，习惯上采用it作形式宾语，不定式短语作后置宾语的表达形式。

　　2．别和她生气了，她只有五岁。

　　误：Don’t be angry at her. She is only five years old.

　　正：Don’t be angry with her. She is only five years old.

　　析：“生某人的气”应用be angry with sb.; be angry at 表示“因某事而生气”。

　　3．当我经过教室时，听见她正在读书。

　　误：I heard him read a book when I walked past the classroom.

　　正：I heard him reading a book when I walked past the classroom.

　　   析：hear sb. doing sth. 表示“听见某人正在做事”，强调听见的动作正在进行中；hear sb. do sth. 表示“听见某人做了某事”，听见的是动作的全过程。如：We often hear Lucy sing this song.

　　4．米沙拒绝和他们一起住。

　　误：Misha refused living with them.

　　正：Misha refused to live with them.

　　析：动词want, wish, hope, decide, refuse, learn等词之后应加不定式作宾语。

　　5．这双鞋看起来不错。

　　误：This pair of shoes look nice.

　　正：This pair of shoes looks nice.

　　析：这句话的主语不是shoes，而是前边的pair，故谓语动词应用单数形式。

　　6．你长大后要干什么？

　　正：What are you going to do when you grow up?

　　误：What are you going to be when you grow up?

　　析：这里的“干什么”，其实际含义是“要成为什么样的人”，动词be具有这层含义。
