Question

定语从句的几个问题，急啊 忘解答！！！十分感谢

he has got himself into a dangerous situation___he has no control.
A because B as C over that D over which选几 为什么
was it he who the professor regarded with such contempt?
这里用he who 而不是who he?为什么
sunday is a holiday,__most people do not go to work. 空中为什么是when而不是which？

from time to time we must look up words__空中用whose meanings we do not know 还是whose meanings we are not familar？为什么～希望有人告诉我 感激啊
1选d

Answer 1

1B 2变成陈述句是 It was he ( 应该是him 吧？) who the professor regarded with such contenpt. 3.which是关系代词 在从句中充当 主语 或者 宾语。本题从句 主语宾语已经有，所以不用which，而可添加时间状语

Answer 2

第一题选 D，第二题 关系代词肯定要放在先行词的后面,所以是he who. 第三题选when,这道题是先行词在定语从句中做状语,因此用when，第四题是whose 引导的定从,可以番译成"它的" 本来可详细点但只能输入100字 抱歉

Answer 3

3. 因为先行词是a holiday，在非限制性定语从句中做do not go to work的时间状语，所以要用表时间的关系的副词when

4. 空中用whose meanings we do not know，
whose meanings we are not familar后应该有with
