解题思路： 定语从句
解题过程：
由于题目过多,所以这里只讲解题思路.
1.答案C. 此为非限定性从句，which代替前面的句子.
2.答案A..they had做定语从句，后跟have difficulty (in)doing sth.. 句型.应该是:they have a lot of difficulty (in) developping the personal computer “他们在发展个人电脑方面有很多困难” .
3.答案D.定性从句.先行词指人可以用who.
4答案D.原题中the应该去掉.whose 在定语从句中作定语。
5.答案D.主句中先行词是situation,which在定语从句中复指situation,但只用which 不行,因为这一部分在从句中要做状语.这样说你可能会糊涂.我把这个句分成两个句子写,是这样的:
1.Have you ever been in a situation?
2.In the situation,you can't agree with the one who you know is right.
意思是:你遇到过这种情形吗---(在这种情形中,)你明明知道某个人是对的,却不能支持他.
6.答案B.about介词"关于"与句中的question有联系,不能丢.
