强调句型结构及用法分别是什么?
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。
例子:It was yesterday that he met Li Ping.他是昨天遇见李平的。
2、一般疑问句的强调句型
同上,只是把is/ was提到it前面。
例子:Was it yesterday that he met Li Ping?他是昨天遇见李平的吗?
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 +其他部分?
例子:When and where was it that you were born?你是什么时候在哪里出生的?
4、not…until…句型的强调句
句型为:It is/ was not until +被强调部分+that +其他部分
例子:It was not until his wife came back that he went to bed.直到他妻子回来,他才上床睡觉。
5、谓语动词的强调
A. 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
例子:Do be careful when you cross the street.过马路时,务必(千万)要小心啊!
