　　根據英語強調結構的基本格式it is (was)that (who)可知，不管被強調成分為指時間或地點，還是指原因或方式等，其后一律要用that，不可用when, where, why, how等。至于其中的who，它只用于被強調成分指人的場合。如：

　　他是昨天晚上才第一次親她。

　　誤：It was last night when he kissed her for the first time.

　　正：It was last night that he kissed her for the first time.

　　我昨天是由于想買本字典而進城的。

　　誤：It was because I wanted to buy a dictionary why I went to town yesterday.

　　正：It was because I wanted to buy a dictionary that I went to town yesterday.
