答案解析.
1. D。what made matters worse是主语从句(注意其后有谓语动词was)，相当于the thing that made matters worse。
2.C。答句为省略句，其完整形式为I was trying to prove to the police where I was last night，在此where引导的是-一个宾语从句。类似地，
3.D. what引导的是表语从句，what 在此相当于the things that。
4.D。根据其后的blackorwhite可推知。
5. C。whether引导表语从句。意为“是否”。句意为“医生真正怀疑的是是否我妈妈能很快从疾病中复原”。
6. C。此题考查whatever= anything that,相当于一个 定语从句。选项A在that前加anything,其他选项不符合题意。
7. A介词to后面是宾语从句，要用引导词，排除C; no matter which不能引导名词性从句，只能引导状语从句，排除D; whoever只能作主语，而本题缺的是定语，排除B.
