典型例题分析： 1) It was last night ____ I saw the film Star Wars． A. who B. when C. that D. which

部分 + that (who) +主谓句。强调句的连词

分时, 要把否定形式放入被强调部分。如:
He didn’t leave until l returned. = It was not until I returned that he left.
I didn’t realize she was a famous film star until she took off her dark glasses. → Not until she took off her dark glasses did I realize she was a famous film star. → It was not until she took off her dark glasses that I realized she was a famous film star.
4. 判断是否是强调句, 可把 It is / was … that 去掉, 剩余部分如果是一个完整的 句子, 就是强调句。 It was in the street that I met her father. →In the street I met her father. It was because she was ill that they didn’t ask her to do the job. →Because she was ill, they didn’t ask her to do the job.
