21、Although he was listening, he didn’t hear (C) because there was so much noise.
A what said
本题中what作疑问词引导名词性从句作了动词hear的宾语。关于名词性从句请大家再复习一下9月份的课程笔记。
22、We are given just so much food (A) will keep us alive .
A as
so much…as结构中的as为准关系代词，作keep的主语，as等于as the food which
23、The rich woman offered a reward to (C) find her lost car.
A who could
空格前无先行词，且从句中缺主语，由此判定只能用复合关系代词whoever，助动词could与主句中offered相对应。
24、The boy (A) I believed to be honest deceived me.
A whom
to be是不定式，乃非谓语动词，因此判定从句中的谓语动词是believed, 主语为I ，所以从句缺宾语，且先行词是人，故而用关系代词whom，作believed的宾语，to be honest为宾语补语。
25、The clever boy made a hole in the wall, （C） he could see what was happening inside the house.
A at which
本题为非限定性定语从句。先行词the hole in the wall 是物不是人，关系代词用which，再者从句中不缺成分，故而关系代词之前必须加介词。此处through为介词，表“凭借”。
26、The age （D） children can go to school is seven.
A
在几岁的年龄，用介词at。age是名词年龄而不是时间，故而用which不用when
27、The dog, （D）she used to be afraid, is her favourite animal now.
A what
be afraid of…“害怕”，which在从句中作宾语。
28、The speed （A） Tom drives his car is too high.
A at which
在某一个速度上，用介词at。
29、Tom is the boy（D） I went to the cinema together.
A whom
together with“同……一起” whom在从句中作宾语
30、In the office I never seem to have time until after 5:30 p.m. （D） time many people have gone home.
A in which
我们知道，在具体的一时刻是用介词at。但at 加时间点与by 加时间点有何区别呢？
at：就在这一时刻
by：到这个时间点为止的一段时间
很显然，题目中many peole是在5：30以后一段时间内的任意时刻回家的，而不可能都是在5：30这个时刻都在做回家的动作。
