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

A. needn't do B. needn't have done
C. mustn't do D. shouldn't have done
【解析】選D “情態動詞 + 完成時態”用來表示對過
去某一事實的假設或推測，根據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?
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.
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.
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.
A. should B. must
C. wouldn't D. can't
【解析】選A 根據下文“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.
A. shouldn't B. couldn't
C. mustn't D. needn't
【解析】選B“情態動詞 + 完成時態”用來表示對過

用"can't / couldn't have done"。本句譯為：當事故發生時
我不可能大于六歲。
( )7. -- Do you know where David is? I couldn't find
him anywhere.
