1. 强调句的基本句型:It is/was +被强调的成分+that/who/whom+其它成分,如:
It is they who/that will have a meeting tomorrow. (强调主语)
It is a meeting that they will have tomorrow. (强调宾语)
It is tomorrow that they will have a meeting. (强调时间状语)
2. not...until...句型的强调句:It is/was not until+被强调部分+that+其它成分,如:
It was not until 1920 that regular radio broadcasts began.
It was not until she took off her dark glasses that I realized she was a famous film star.
注意此结构与倒装句的区别,如:
It was not until Li Ming finished his homework that he watched TV. (强调句)
Not until Li Ming finished his homework did he watch TV. (倒装句)
Not until all the people get on it that the bus will go. (强调句)
Not until all the people get on it will the bus go. (倒装句)
3. 谓语动词的强调:It is/was...that...结构不能强调谓语,需要强调谓语时,用助动词do或did,如:
Do be careful when you cross the street.
He did write to you last week.
