一、以形式主语it引导的句型。

It (so) happened(chanced) that +clause. = sb. happened /chanced to do sth. =sb.did sth. by chance. 如:

It happened that he was out when I got there. 当我到那儿时,碰巧他不在。=He happened to be out when I got there.= It chanced that he was out when I got there= He was out by chance when I got there.

句型2.

It seems that sb. do/ be doing/ have done/ had done= Sb. seems to do/ be doing/ have done/to be done/to have been done(还有动词appear等可这样使用)如:

句型3.

It is / was+被强调的部分+that(who)+剩余的部分.如:

It wasn't until he came back that I went to bed.直到他回来我才睡觉。(一定要注意被强调句型中的谓语动词否定的转移)。 It was because he was ill that he didn't come to school today.只因为他有病了今天没有来上学。(只能用because而不能用for, as 或since)

It is I who am a student. 我确实是个学生。(句中am不能用are来代替。)

句型4.

It is high time (time/ about time)+ (that) 主语+should do / did+其它。(从句中的谓语动词用的是虚拟语气。)如:

句型5.

It is / was said ( reported…)+that+从句. 如:

It was said that he had read this novel.据说他读过这篇小说。=He was said to have read this novel.

It is impossible / necessary/ strange…that clause.(从句中的谓语用should+do / should have done,其形式是虚拟语气。)如:

句型7.

It is + a pity/ a shame…that clause.(注意从句中的谓语动词用should do或should have done的形式,但should可以省略。)如:

He didn't come back until the film ended. It was a pity that he should have missed this film. 他直到电影结束才回来。他没有看到这部电影真可惜。

句型8.

It is suggested / ordered/ commanded /…that +clause.(从句的谓语动词用should do, 但should可以省略。)如:

It is suggested that the meeting should be put off.有人建议推迟会议。

句型9.

It is/was+表示地点的名词+where+从句。(注意本句不是强调句型,而是以where引导的定语从句。)如:

It was this house where I was born.请比较:It was in this house that I was born.(后一句是强调句型。)

句型10.

It is / was +表示时间的名词+when+从句。(注意本句型也不是强调句型,而是以when引导的定语从句。)如:

It is well-known that+从句。如:

It is +段时间+since+主语+did. 请比较:

It was five years since he left here.(同上)

注意下列句型的翻译:It is five years since he lived here.他从这儿搬走已经有五年了。

句型13.

It +谓语+段时间+before+主语+谓语.( before引导的是时间状语从句。) 如:

It wasn't long before the people in that country rose up.没有多久那个国家的人民就起义了。

句型14.

It is +形容词(possible, impossible, necessary等) +for+ sb.+ to do. 如:

二、定语从句:

句型16.

由as引导的非限定性的定语从句。如:

句型17.

由which引导的非限定性的定语从句。如:

He is a professor, which I have been looking forward to becoming. 他是个教授,那是我一直盼望的职业。(因为先行词professor是表示职业的名词,因此引导词用which,而不用who。
