1. She gave it back to me. 强调it。（据说强调代词时，只能用who？）
2. I used to live in a small house. 强调“一幢小房子”。（live后面的in要跟着强调吗？或者说强调不及物动词的介词宾语时，介词要跟着强调吗？）
It was a small house that I used to live in. 这样感觉就是定语从句了。
It was in a small house that I used to live. 这样还是很奇怪，live后面没有in空空的。
3. Chandler painted the wall white in the room yesterday.强调the wall。（改写后painted直接跟white不会奇怪吗？还是要来个形式宾语it？）
4. 有看到“She wondered when it was that we could complete the experiment.
”进一步改成“When was it that she wondered we could completer the experiment?”，这是怎么回事呢？
1. It was it that she gave back to me.这种说法我迄今为止都没有听过，正统说法是that为万能引导词，而当被强调部分为sb时，引导词才会使用who/whom.2. It was a small house that I used to live in.楼主无须理会这些情况，只要强调哪个，就把哪个成分放于it is/was和引导词之间即可。有时候强调句型和定语从句的确一样，但是有时候也不一样。如果该句是：It was a small house which I used to live in.或：It was a small house in which I used to live.或：I...
