似是而非的非谓语动词的考点归纳
一、形式上是考查非谓语动词，但实质上是考查省略句
①The flowers his friend gave him will die unless _______ every day. (四川卷)
A. watered B. watering B. water D. to water
答案为A。unless watered可视为unless they are watered之省略。又如：
②No matter how frequently _______, the works of Beethoven still attract people all over the world. (广东卷)
A. performed B. performing C. to be performed D. being performed
答案为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
答案为D。Sound good为It sounds good之省略。
二、形式上是考查非谓语动词，但实质上是形容词的用法
①He is very popular among his students as he always tries to make them ______ in his lectures. (江苏卷)
A. interested B. interesting C. interest D. to interest
答案为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. (全国卷)
A. Surprising B. Surprised C. Being surprised D. To be surprising
答案为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。
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. (全国I)
—_______ her this weekend?
A. Why not visit B. Why not to visit C. Why not visiting D. Why don’t visit
答案为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. (广东)
A. forget B. forgot C. forgetting D. to forget
答案为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。
四、形式上是考查非谓语动词，但实质上是考查祈使句
①Mary, _______ here — everybody else, stay where you are. (全国I)
A. come B. comes C. to come D. coming
答案为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. (重庆卷)
A. Finding out B. Found out C. Find out D. To find out
答案为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。
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. (上海卷)
A. sitting B. having sat C. to sit D. sat
答案为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
答案为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。
③First _______ the rice by washing it, then _______ it in boiling water.
A. prepare, cook B. preparing, cooking C. preparing, cook D. prepare, cooking
答案为A。题干部分为两个并列的祈使句，故均用动词原形。
