it was in New zealand ____ Elizabeth first met Mr.Smith.
这个句子我觉得是填that，标准的强调句型，但大家老师说填where也可以。强调句的it无所指，假如把这个句子中的it理解为指代某个东西，就变成：它（这个东西）是在新西兰。然后用 where 引导定语从句对新西兰进行限定，伊丽莎白首次遇到史密斯先生的新西兰。如此理解能否？
It was in New Zealand ____ Elizabeth first met Mr. Smith.
【答】这个句子填where的话，强调句不允许，定语从句讲不通。因此，填that万无一失！
假如被强调的是地址副词，其余部分除去用that引导外，偶见用where引导。
假如被强调的是时间副词，其余部分除去用that引导外，偶见用when引导。
假如被强调的地址或时间是介词短语等其他形式，则不可以用when 或where引导，只用that。
比如：
1. It was yesterday that he bought an English book in town.
2. It is here that he must wait for her.
3. It was in this room that we had a heated discussion.
4. It is at ten o’clock that the meeting will take place.
