what的用法3.------ is it ----- has made Peter ----- he is today

1.答案：D.
2.翻译：是什么使得皮特变成今天这个样子?
3.
1）此题考查强调句型的特殊疑问句.
2）强调句型基本结构是：It is/was + 被强调部分 + that + 句子未被强调部分.
去特殊疑问句即对被强调部分提问,变成：
特殊疑问词 + is/was it that + 句子未被强调部分?
3）此题正是如此,我可以先放入一个sth到其中,即为：
It is sth that has made Peter what he is today.
对sth提问,即：What is it that has made Peter what he is today?
所以前两空为What,that.
4）至于最后一空,made是使役动词,Peter是宾语,而名词性从句what he is today则是宾语补足语.
这个名词性从句在he is today后面明显缺少表语,所以必须用what.
如果用that,它在名词性从句中是不能充当成分的,那么此从句表语就缺少了.
名词可以充当宾语补足语,如：We made Peter our monitor.我们使得皮特成为我们的班长.
