1. A.
   ought to not
2. B.
   ought not to
3. C.
   not ought to
4. D.
   does not ought to

Answer 1

B
試題分析：句意：她不應(yīng)該半路停止工作。這里是ought to have done否定的形式，應(yīng)該是ought not to have done，故選B。
考點(diǎn)：考查情態(tài)動(dòng)詞的用法。
點(diǎn)評(píng)：本題難度適中。對(duì)于情態(tài)動(dòng)詞的各種否定形式也是高考�？嫉膬�(nèi)容，需要考生牢記它們的用法，這里考生容易誤選A。
即學(xué)即練：—I didn’t tell my parents the secret yesterday.
—But you __________.
A. ought to do          B. ought to
C. should               D. ought to have
解析：D。句意：因?yàn)樯习刖涫沁^(guò)去時(shí)，所以是對(duì)過(guò)去事實(shí)表示推測(cè)，應(yīng)該用“情態(tài)動(dòng)詞+完成時(shí)”。而D項(xiàng)就是這種形式的省略。
