几道高中英语选择题（关于复合句。正确答案已知，请给出解释）

1. Mother was worried because little Alice was ill,especially ____ father was away in France.
a. as b. that c. during d. if
正确答案为a，请问为什么c不对？另外可不可以填when？

2. Sarah hopes th become a friend of ____ shares her interests.
a. anyone b. whomever c. whoever d. no matter who
正确答案为c，我选了b。为什么b不对？

3. In the office I never seem to have time until after 5:30 p.m.,____ many people have gone home.
a. whose time b. that c. on which d. by which time
这题我觉得没一个选项对，但正确答案是d。请问原因？

以上3题，请高手赐教。

Answer 1

1. 用as 或when都行，但during 是个介词，后面不能跟句子。
2。 C。 B不行，因为whomever同时要在句中作宾语，而____ shares her interests.从句少的是主语
3。many people have gone home 用的现在完成时，那前面用的应该是D,意思是到那个时间，许多人已经回家了。by...加时间通常句子用完成。

Answer 2

c 介词，不能引导从句 when 也可以
在从句中做主语的就要用主格 whoever
many people have gone home是完成时，所以要用表示完成的介词，就是by，到。。。为止

Answer 3

第一题C选项是介词，不能接从句；第二题介词后的关系词坚持“就从不就主”的原则，它相当于anyone who；第四题答案没问题，属于介词加关系代词一类。
