Don't you think it is time you -------smoking?
a. give up b. would give up c. gave up d . must give up选哪个,为什么?

选 c.
It's time + that clause 时,that可省略,time可由high,about修饰,从句中的谓语动词有两种形式,或者用动词的过去式(be用were)；或者用shoud + 动词原形（should不能省略).此句型为虚拟语气句型,表示“现在某人该做某事了”.含有该事早该去做而未做,现在去做似乎都为时已晚的意思.例：
It's time （that）we went to bed.
我们该去睡觉了.
It's high time that the article were published.
发表这篇文章是适时的.
It's time you should do cleaning.
你该去打扫卫生了.
