高中英语一道单选
Nobody knows ________broke into the house last night and stole the important papers
A.who was it that B.it was who that
C.who it was that D.that it was who
于是完全分不清啊啊.选C,为什么其他三个不行,另外这是一个什么句?
B 和D为什么不行
答
没有人知道是谁在昨晚进入这个房子盗窃了重要的文件。选则中的it就是指代盗窃这件事。that连接词放句末。这是个复合句。双宾。
答
who后面的从句是强调句型，陈述句语序应该是：it was who that broke into the house last night and stole the important papers.
然后如果是疑问句的话，应该为who was it that ......?
但是因为这里的who是从句，虽然是疑问句语气，但是从句中必须是陈述句的语序，所以是：who it was that......
答
强调句的疑问句式充当了一个宾语从句,语序要变成正常语序.本来这个疑问句是：Who was it that broke into the house last night and stole the important papers 究竟是谁做完闯入房间并偷了重要文件?该句式是固定的...
