陷阱一：形式上是考查非谓语动词，但实质上是考查省略句

1. The flowers his friend gave him will die unless ______ every day. (2007四川卷)

A. wateredB. watering     C. water     D. to water

【解析】答案选A。unless watered可视为unless they are watered之省略。又如：

Unless changed, this law will make life difficult for farmers. 这项法令除非进行修改，否则将给农民的生活造成困难(from www.nmet168.com)。

2. No matter how frequently ______, the works of Beethoven still attract people all over the world. (2006广东卷)

A. performed                         B. performing

C. to be performed     D. being performed

【解析】答案选A。No matter how frequently performed可视为No matter how frequently they are performed之省略。

3. - I was wondering if we could go skiing on the weekend. 

- _______ good. (湖北卷)

A. Sound     B. Sounded     C. Sounding     D. Sounds

【解析】答案选D。Sound good为It sounds good之省略。

陷阱二：形式上是考查非谓语动词，但实质上是形容词的用法

1. He is very popular among his students as he always tries to make them ______ in his lectures. (2007江苏卷)

A. interested     B. interesting      C. interest      D. to interest

【解析】答案选A。过去分词interested在此已转化为形容词，interested in意为"对……感趣"。

2. ______ and happy, Tony stood up and accepted the prize. (2006全国卷)

A. Surprising     B. Surprised     C. Being surprised     D. To be surprising

【解析】答案选B。由于与形容happy并列，故可排除C和D。又因为是用以说明主语Tony的心情，故用surprised，不用surprising (from www.nmet168.com)。

陷阱三：形式上是考查非谓语动词，但实质上是考查某种句式

1. -It's a long time since I saw my sister. (2007全国I)

-___A___ her this weekend?

A. Why not visit      B. Why not to visit 

C. Why not visiting   D. Why don't visit 

【解析】答案选A。Why not…为英语中常用句式，用于提出建议，其后只接动词原形，不接不定式或现在分词。注意不能选D，但是若D改为Why don't you visit也可以选。

2. If you are planning to spend your money having fun this week, better ______ it-you've got some big bills coming. (2004广东)

A. forget     B. forgot              C. forgetting            D. to forget

【解析】答案选A。此处的better实为you'd better之省略。根据英语习惯，had better之后只能接动词原形，故选A

 陷阱四：形式上是考查非谓语动词，但实质上是考查祈使句

1. Mary, ______ here - everybody else, stay where you are. (2006全国I)

A. come     B. comes C. to come     D. coming

【解析】答案选A。此处考查祈使句的用法，故用动词原形。

2. -What should I do with this passage?

- _____the main idea of each paragraph. (2005重庆卷)

A. Finding out     B. Found out      C. Find out     D. To find out

【解析】答案选C。此处考查祈使句的用法，故用动词原形。其实，此题也可视为You should find out…之省略。

陷阱五：形式上是考查非谓语动词，但实质上是考查并列句

1. At last, we found ourselves in a pleasant park with trees providing shade and _____down to eat our picnic lunch. (2005上海卷)

A. sitting     B. having sat      C. to sitD. sat

【解析】答案选D。由句中的and可知，此句为并列结构，且空格处填sat，与其前的谓语动词found并列。

2. _____ many times, but he still didn't understand it.

A. Having been told      B. Though he was told

C. To have been told                                 D. He was told

【解析】答案选D。句中的并列连词 but 表明整个句子为并列句，同时表明but前应是一个独立的句子，而不能是一个非谓语动词短语(所以不能选A或C)，又因为though为从属连词，用以引导让步状语从句，它与连接并列句的并列连词 but 不"兼容"，所以也不能选B (from www.nmet168.com)。

3. First ______ the rice by washing it, then ______ it in boiling water. 

A. prepare, cook                             B. preparing, cooking

C. preparing, cook                              D. prepare, cooking

【解析】答案选A。题干部分为两个并列的祈使句，故均用动词原形。
