It’s time we _______ the lecture because everybody has arrived.
选项:
a、will start
b、shall start
c、start
d、started

Answer 1

应该选择D，It is time (that) sb. did sth.
具体解释：
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。
