  小升初英语语法祈使句知识点:不要混淆祈使句与非谓语动词

  有这样一道语法考题,该用动词原形?还是用非谓语动词?

  _________ the road round to the right and you’ll find his house.

  A. Follow B. Following C. To follow D. Followed

  【分析】此题容易误选B或C,许多同学一看选项就想当然地认为,选现在分词表示时间或伴随,选不定式表目的。此题的关键是要注意句中的连词and,它表明整个句子是一个并列句,即 and 前后应各是一个独立的句子,而不应是一个非谓语形式的短语,所以此题的正确答案应选A,即 and 前是一个祈使句。比较以下两题:

  (1) _________ the road round to the right, she found his house.

  A. Follow B. Following C. To follow D. Followed

  【分析】此题应选B,现在分词短语表时间。

  (2) _________ the road round to the right, the blind man asked a boy to guide him.

  A. Follow B. Following C. To follow D. Followed

  【分析】此题应选C,不定式短语表目的。

  注意以下各题均应选A,均因为句中的并列连词 and(填空句为祈使句):

  (1) _________ the milk and set a good example to the other children.

  A. Drink B. To drink C. Drinking D. Having drinking

  (2) _________ me, and don’t just stand there laughing.

  A. Answer B. To answer C. Answering D. To be answering

  (3) _________ me , and then try to copy what I do.

  A. Watch B. Watching C. To watch D. Have watching

  (4) _________ through this book and tell me what you think of it.

  A. Look B. Looking C. To look D. Having looked

  (5) _________ it with me and I’ll see what I can do.

  A. Leave B. Leaving C. If you leave D. When left

  注:有时可能不用连词,而用破折号(答案均选B,填空句为祈使句)。如:

  (1) _________ down the radio — the baby’s asleep in the next room.

  A. Turning B. Turn C. Turned D. To turn

  (2) _________ some of this juice — perhaps you will like it.

  A. Trying B. Try C. To try D. Having tried

  以下各题也应选A,是因为句中的从属连词 when, before, until 等(填空句为祈使句):

  (1) _________ left when you get to the end of the street.

  A. Keep B. Keeping C. To keep D. Kept

  (2) _________ you hand over your mouth when you cough.

  A. Put B. Putting C. To put D. To be putting

  (3) _________ him enough time to get home before you telephone.

  以下各题也应选A,即填空句为祈使句:

  (5) To test eggs, _________ them in a bowl of water: if they float they’re bad, if they sink they’re good.

  A. put B. putting C. to put D. to be putting

  但是,以下各题情形有所不同,所填部分为目的状语(用不定式,即答案均为B):

  (1) _________ late in the morning, Bob turned off the alarm.
