(强调宾语) It was in the lab that my father did the experiment yesterday evening. (强调地点状语) It was yesterday evening that my father did the experiment in the lab. (强调时间状语) 又如:It is I that/who am wrong.

▲ 文中句子强调的是由because引导的原因状语从句。强调原因状语从句时,只能用because

引导,不能用since/as.

Eg. It was because she was ill that she didn’t come to work.

强调句型的一般疑问句和特殊疑问句形式:一般疑问句的强调形式,只需将is/ was 提前,移至句首即可,即:Is/ Was it … that …。特殊疑问句的强调形式,须将陈述句变成一般疑问句,再在句首加上疑问词,即:疑问词(被强调部分)+is/was + it + that + 句子其余部分

It was last year that the building was completed.
