專四英語語法輔導(dǎo)試題2017

  在現(xiàn)代英語中,have to 中不定式和疑問句式既可以按照助動(dòng)詞的變化規(guī)則構(gòu)成,也可以按照行為動(dòng)詞的變化規(guī)則構(gòu)成。

  Have you to finish the work before supper?

  Do you have to finish the work before supper?

  have got to 常可同have to換用,但有時(shí)表示不同的含義。比較:

  He has to report to the headquarters every two days.(例行公事,習(xí)慣動(dòng)作)

  He has got to report to the headquarters every two days.(一道指示或命令,必得每天報(bào)告一次)

  另外,作“有”解時(shí),have got和have通常是可以換用的,have got更口語化,但有時(shí)表示不同的含義。比較:

  The man has a blind eye.那人有一只眼瞎了。

  The man has got a blue eye.那人有一只眼被打青了。

  must not表示禁止,是說話人強(qiáng)有力的勸告或命令,意為“一定要,不準(zhǔn)”。因此,在回答由must引導(dǎo)的問題時(shí),如果是否定的回答,表示“不必,沒有必要”,不能用mustn't,而要用needn't或don't have to.試比較:

  You must not drive fast.你不能開快車。(路險(xiǎn)或有速度限制)

  You needn't drive fast.(時(shí)間充裕)

  You must not tell others.(警告)

  You needn't tell others.(沒有必要)

  needs為副詞,相當(dāng)于necessarily, of necessity. must needs和needs must均可表示“必須,必定,不得不”,這層意義上可以通用;但must needs還可表示“偏偏,偏要”,含有譏諷、不滿的意思,而needs must則一般無這層意思。例如:

  I must needs go there now.

  我現(xiàn)在非到那里去不可。(可用needs must)

  Needs must when the devil drives.

  情勢(shì)所迫不得不那樣。

  She must needs go away when I want her.

  我正需要她時(shí),她偏偏離開了。(不可用needs must)

  The telephone must needs ring when I went to bed.

  我上床睡覺時(shí)偏偏有人來電話。(不可用needs must)

  need指主語的主觀特需情況而使之必要。need既可以作助動(dòng)詞,又可以作行為動(dòng)詞。作助動(dòng)詞時(shí),need沒有人稱和數(shù)的變化,后接不帶to的不定式(動(dòng)詞原形),否定式為needn't.作行動(dòng)動(dòng)詞時(shí),need同別的行為動(dòng)詞一樣,有人稱和數(shù)的變化,后接帶to的不定式,否定式要在前面加don't(doesn't, didn't),疑問句用do (does, did) 提問。例如:

  There need be no hurry, need there?

  He need never know. (=He never needs to know.)

  I need only add a few words. (= I only need to add a few words.)

  比較:

  Father sent me the book, so I didn't need to write to him for it.

  父親把那本書寄來了,所以我不必為此給他寫信了。(信沒寫)

  Father sent me the book, so I needn't have written to him for it.

  父親把那本書寄來了,所以我本不該為此再寫信給他的。(信已寫)

  She didn't need to come.她不必來的。(實(shí)際也沒來)

  She needn't have come.她本來不必來的。(但卻來了)

  Note:

  作助動(dòng)詞用時(shí),need只用于疑問句中和否定句中,在肯定句中常用must, have to, should, ought to等。例如:

  Need you do it right now? I needn't, but he must.

  She doesn't need to be told. She has already known it.

  (客觀情況使得告訴她沒有必要:她已經(jīng)知道)

  She needn't be told. We should keep it secret from her.

  (主觀上不愿告訴)

  完成下面五道選擇題目:

  1. You__ Jim anything about it. It was none of his business.

  A needn't have told B needn't tell C mustn't have told D mustn't tell

  2.As it turned out to be a small house party, we __ so formally.

  A need not have dressed up B must not have dressed up C did not need to dress up D must not dress up

  3.We could__ him with a detached house when he came, but he had specifically asked for a small flt.

  A provide B have provided C not provide D not have provided

  4.He__ the 8:20 bus becasue he didn't leave home till 8:25.

  A couldn't have caught B ought to have caught C shouldn't have caught D must not have caught

  5."She must be in the dormitory now."

  "No, she __ be there. I saw her in the classroom a minute ago."

  A mustn't B can't C couldn't D wouldn't

  答案:AABAB
