不要混淆祈使句與非謂語動詞

 

有這樣一道語法考題,該用動詞原形?還是用非謂語動詞?

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

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

【分析】此題容易誤選BC,許多同學一看選項就想當然地認為,選現在分詞表示時間或伴隨,選不定式表目的。此題的關鍵是要注意句中的連詞and,它表明整個句子是一個并列句,即 and 前后應各是一個獨立的句子,而不應是一個非謂語形式的短語,所以此題的正確答案應選A,即 and 前是一個祈使句。比較以下兩題:

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

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

【分析】此題應選B,現在分詞短語表時間。

(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】此題應選C,不定式短語表目的。

注意以下各題均應選A,均因為句中的并列連詞 and(填空句為祈使句):

(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:有時可能不用連詞,而用破折號(答案均選B,填空句為祈使句)。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

以下各題也應選A,是因為句中的從屬連詞 when, before, until 等(填空句為祈使句):

(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.

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

A. Give                            B. To give                     C. Giving                          D. Given

(4)_________ until the lights have turned to green.

A. Wait                            B. To wait                     C. Waiting                        D. Having waited

(5) _________ the pieces of cloth with a loose stitch before finally sewing them together.

A. Join                             B. To join                      C. Joining                        D. Joined

以下各題也應選A,即填空句為祈使句:

(1) Don’t give me a long account, just _________ the plain facts.

A. tell                              B. telling                        C. to tell                           D. to be telling

(2) First _________ the rice by washing it, then _________ it in boiling water.

A. prepare, cook               B. preparing, cooking     C. preparing, cook             D. prepare, cooking

(3) Don’t sit there watching — _________ and help me!

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

(4) Don’t waste your money on silly things — _________ it.

A. save                            B. to save                        C. saving                        D. having saved

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

但是,以下各題情形有所不同,所填部分為目的狀語(用不定式,即答案均為B)

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

A. Sleep                           B. To sleep                     C. Sleeping                      D. Having slept

(2) _________ the early bus, Mr Smith got up at six.
