It is + 被强调部分 + that ...
该句型是[url]http://强调句型[/url]。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，that可以由who换用。如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断[url]http://强调句型[/url]与其它从句的方法。

It is not until + 被强调部分 + that ...
该句型也是[url]http://强调句型[/url]。主要用于强凋[url]http://时间状语[/url]，译[url]http://成汉[/url]语”直到．．．才．．．”，可以说是 not ... until ... 的强调形式。

= Not until she took off her dark glasses did I realize she was a famous film star.
= I didn’t realize she was a famous film star until she took off her dark glasses.
It is clear ( http://obvious, true, possible, certain....) that .....
该句型中it 是[url]http://形式主语[/url]，真正的主语是that 引导的[url]http://主语从句[/url]，常译为”清楚（显然，真的，肯定．．．）”　是[url]http://主语从句[/url]最常见的一种结构。

该句型中的it 仍是[url]http://形式主语[/url]，真正主语是that 引导的[url]http://主语从句[/url]。该结构常译为”据说（据报道，据悉．．．）”。
It is said that he has come to Beijing.

6. It is suggested ( ordered ... ) that ...
该句型和上一个同属一个句型。主句中的过去分词是表示请求，建议，命令等词时，that　后的从句要用[url]http://虚拟语气[/url]（should + [url]http://动词原形[/url]），should 可以省。常译为”据建议；有命令．．．）
It is suggested that the meeting ( should ) be put off.
It was ordered that we ( should ) arrive there in two hours.

It is a pity ( a shame ... ) that ...
该句型中，that后的从句一般用[url]http://虚拟语气[/url]（should + [url]http://动词原形[/url]），should可省去．表示[url]http://出乎意料[/url]，常译为”竟然”。没有这种意义时，则不用虚拟语气。
It is a pity that such a thing ( should ) happen in your class.
这种事竟然发生在你们班上，真是遗憾！

It is time ( about time ,high time ) that ...
该句型中that 后的从句应该用虚拟语气，值得注意的是① 常用过去时态表示虚拟．② 有时也用should + 动词原形，should 不能省。常译为”是（正是）．．．的时侯．．．”。
It is time that children should go to bed.
= It is time that children went to bed.
It is .... since ...
该句型主要用作处理[url]http://瞬间动词[/url]的完成时，又要和表示一段时间的[url]http://时间状语[/url]连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是[url]http://一般过去时[/url]态，而且是[url]http://瞬间动词[/url]。如果主句是[url]http://一般过去时[/url]，从句则用[url]http://过去完成时[/url]。
It is ( has been ) 5 years since his father died.

这是一种特殊的用法，常出现于[url]http://黑人英语[/url]和其他非正式的场合，所以英语中这种类型的[url]http://双重否定[/url]并不是肯定的意思。这里，ain't 后面的no 是表示强调，并不会把整句话变成相反的意思。
