Answer 1

"答案A
当不定式省略时，通常只保留不定式符号to。
(1)-- Would you go there with me?
-- I'm glad to.
(2)-- Do you want to sing them an English song?
-- I prefer not to.
但当不定式是to be，to have时，则通常保留be和have。
(1)-- Aren't you the manager?
-- No,and I don't want to be.
(2)-- He hasn't finished yet.
-- Well,he ought to have.
本题属第一种情况，故选A．"
