(一)[基础讲解]
(一)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。
It was Tom that met your brother in the park yesterday.
汤姆昨天在公园里遇见了你哥哥。
2、一般疑问句的强调句型:
同上,只是把is/ was提到it前面。
Was it Tom that your brother in the park yesterday?
昨天你哥哥在公园遇见的是汤姆吗?
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?
When and where was it that you were born? 你是什么时间在哪儿出生的?
4、注意:a.构成强调句的it本身没有词义;
b.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;
c.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 + 其它部分
普通句:I didn"t realize she was a famous film star until she took off her dark glasses.
强调句:It was not until she took off her dark glasses that I realized she was a famous film star. 直到她摘下墨镜我才意识到她是位着名影星。
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。
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,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。
