一、常考的强调句结构是 it 引导的句子。
it is (was) 被强调部分 that (who) 句子其他部分。
此结构强调的成分仅限于主语,宾语和状语。例如:
it was because of the heavy rain that he came late.
it was yesterday that tom passed in the maths e_am.
it was not until i had read your letter that i understood the matter.
原句:my father did the e_periment in the lab yesterday evening.
强调主语:it was my father who did the e_periment in the lab yesterday evening.
强调宾语:it was the e_periment that my father did in the lab yesterday evening.
强调时间:it was yesterday evening that my father did the e_periment in the lab. (注意不用when)
强调地点:it was in the lab that my father did the e_periment yesterday evening.
二、强调句还有一种类型,就是用助动词do (did,does) 强调谓语。
she does like this horse. 她的确喜欢这匹马。
please do take care of yourself. 千万保重。
三、注意事项:
被强调成分是主语,who/that之后的谓语动词应该在人称和数上与原句中的主语保持一致。
e.g. it is i who am right.
e.g. it is he who is wrong.
