名词性从句：即从句在整个句中起名词作用,分别可以作主语、宾语、表语、同位语等,所以这类从句包括主语从句考点一：主语从句：主要考查主语从句的引导词；主句的谓语动词,一般用单数.如：
1.That the earth goes around the sun is well-known to everybody.
( = It is well-known to everybody that the earth goes around the sun.)
2.Whether he will come to the meeting is up to his boss.（此时不能用if ）
3.Who will come to the dinner remains a question.
4.What you have said is convincing.
5.How the ancient Egyptians built the pyramids puzzled people for centuries.
6.Why the murderer came back to the scene of crime is a psychological problem.
强调句.通常用it 作形式主语,而that引导一个真正主语
强调句句型
1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分.
e.g.It was yesterday that he met Li Ping.
2、一般疑问句的强调句型：同上,只是把is/ was提到it前面.
e.g.Was it yesterday that he met Li Ping?
3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分?
e.g.When and where was it that you were born?
4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调.
强调主语：It was I that (who) met Li Ming at the railway station yesterday.
强调宾语：It was Li Ming that I met at the railway station yesterday.
强调地点状语：It was at the railway station that I met Li Ming yesterday.
强调时间状语：It was yesterday that I met Li Ming at the railway station.
5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that,who,即使在强调时间状语和地点状语时也如此,that,who不可省略；强调句中的时态只用两种,一般现在时和一般过去时.原句谓语动词是一般过去时、过去完成时和过去进行时,用It was ...,其余的时态用It is ....http://www.english-cn.cn
（二）not ...until ...句型的强调句
1、句型为：It is/ was not until + 被强调部分 + that + 其它部分
e.g.普通句：He didn't go to bed until/ till his wife came back.
强调句：It was not until his wife came back that he went to bed.
2、注意：此句型只用until,不用till.但如果不是强调句型,till,until可通用；因为句型中It is/ was not ...已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了.
（三）谓语动词的强调
1、It is/ was ...that ...结构不能强调谓语,如果需要强调谓语时,用助动词do/ does或did.
e.g.Do sit down.务必请坐.
He did write to you last week.上周他确实给你写了信.
Do be careful when you cross the street.过马路时,务必（千万）要小心啊!
2、注意：此种强调只用do/ does和did ,没有别的形式；过去时用did ,后面的谓语动词用原形.
