2011暑假必備寶典之高一英語知識點總結(jié)Unit7-8(22)

　　    ☆精典題例☆

　　(  ) 1. -- Catherine, I have cleaned the room for you.

　　    -- Thanks. You ____ it. I could managed it

　　    myself. (2005 福建)

　　    A. needn't do    B. needn't have done

　　    C. mustn't do    D. shouldn't have done

　　    【解析】選D  “情態(tài)動詞 + 完成時態(tài)”用來表示對過

　　去某一事實的假設(shè)或推測，根據(jù)上下文可以得知凱瑟琳自

　　己可以做，所以對方“本不必做”。

　　(  ) 2. Mum is coming. What present ____ for your

　　    birthday?  (2005  福建)

　　    A. you expect she has got

　　    B. you expect has she got

　　    C. do you expect she has got

　　    D. do you expect has she got

　　    【解析】選C  do you expect 通常被看作插入語，而不

　　寫成Do you expect what she has got，所以后面的賓語從句

　　仍用陳述語序。

　　(    )3. I always take something to read when I go to the

　　    doctor's ____ I have to wait. (2005  全國II)

　　    A. in case    B. SO that

　　    C. in order    D. as if

　　    【解析】選A   in case引導句子或單獨使用，上面句

　　子中in case I have to wait “以防我去等”，使上下文邏輯通

　　順。

　　(  )4. -- I'm afraid Mr. Wood can't see you until 4

　　    o'clock.

　　    -- Oh, ____ I won't wait. (2005  浙江)

　　    A. no doubt    B. after all

　　    C. in that case    D. in this way

　　話)。

　　(  )5. He ____ have completed his work; otherwise,

　　    he wouldn't be enjoying hirnself by the seaside.

　　    (2005北京)

　　    A. should    B. must

　　    C. wouldn't    D. can't

　　    【解析】選A   根據(jù)下文“否則他在海邊沒法玩得痛

　　快。”可以推出上一句“他本應該要完成他的工作。”should

　　have done表示后悔或責備，意為“本應該做了(但事實上

　　沒做)”。

　　(  )6. I ____ have been more than six years old when

　　    the aecident happened. (2005  天津)

　　    A. shouldn't    B. couldn't

　　    C. mustn't    D. needn't

　　    【解析】選B“情態(tài)動詞 + 完成時態(tài)”用來表示對過

　　去某一事實的假設(shè)或推測。尤其用來表示否定的推測則

　　用"can't / couldn't have done"。本句譯為：當事故發(fā)生時

　　我不可能大于六歲。
