以下强调句如何改写?1.She gave it back to me.强调it.（据说强调代词时,只能用who?）2.I

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：It was a small house where I used to live.
上述这些例句只能算是定语从句.
如果是：It was in a small house that I used to live,则它只能是强调句型.
3.It was the wall that Chandler painted white in the room yesterday.
不要加it,强调句型的结构是固定的,不要以语感来判断.
4.She wondered when it was that we could complete the experiment.
此句采用强调句型的特殊疑问句做宾语从句,主句为主谓宾结构的陈述句she wondered...
不过改成：When was it that she wondered we could completer the experiment?
这种改法说实话,我没有见过,应该属于非正规用法,个人不提倡这种用法.
它等于是把she wondered视为插入语,类似于(do) you think,这种插入语对句子其他成分没有影响,只要求其后的句子采用陈述句序即可.
该句主句是一个强调句型的特殊疑问句：When was it that we could complete the experiment?
最后希望楼主记住以下三点,并直接套用即可：
1.强调句型结构为：It is/was + 被强调部分 + that/who/whom + 句子未被强调部分.
这个句型是固定不变的.
而且特殊疑问句是对被强调部分进行划线提问,用适当的疑问词代替,其他结构正常变化,即为：疑问词 + is/was it + that/who/whom + 句子未被强调部分?
2.其特点是：如果取得it is/was和引导词that/who/whom后,剩下的必须可以组成应该完整的句子（有时候需要调整句序）.
3.not until的强调句型为：It is/was not until + 状语/状语从句 + that + 句子/主句（肯定句）.
如：I didn't go to bed until 11:30 last night.
改成：It was not until 11:30 last night that I went to bed.
再如：I won't go to bed until you come back tonight.
改成：It is not until you come back tthat I will go to bed tonight.
