一般疑问句怎样变成强调句？

Answer 1

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）+ 其他部分。
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 + 其他部分？
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 …… .
二、not … until … 句型的强调句
1. 句型为：It is/ was not until + 被强调部分 + that + 其他部分
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。

Answer 2

强调句句型的一般疑问句形式为：
Is/was it＋被强调成份＋that＋其他？
符合所有句型。
例：
Is he a student?
强调he
Is it he that is a student?
把is it...that 去掉，句意不变。
