It'stime+thatclause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:
1.It'stime(that)wewenttobed.我们该去睡觉了.
2.It'shightimethatthearticlewerepublished.发表这篇文章是适时的.
3.It'stimeyoushoulddocleaning.你该去打扫卫生了.
Itistimethatsbdidsth.这本身就是【定语从句】.这个句式也不适合改为强调句.
time的常用句型有:
Itistimetodosth
Itistimeforsbtodosth
Itistimeforsth
Itistime(that)sbdidsth
shoulddosth最后这两种形式,都是表示【虚拟语气】的句式.
例如:
ItistimethatIworkedharderformydream.
=ItistimethatIshouldworkharderformydream.
该是我为我的梦想而努力的时间了.(表示“幡然悔悟,早该努力”).
对比【强调结构】:
Itwas【atsixo'clockyesterday时间状语,被强调部分】thatImethimattheschoolgate.
Itis【him】that/whomImetatsixo'clockyesterdayattheschoolgate.
强调句型判断:去掉Itis.that后,句子是完整的才是强调句
