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 。

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 sit　　　　　　 D. 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. -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. 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. 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. -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. ______ 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 。

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. 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”。

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。
