Answer 1

1, 分词引导结果状语
2，be reported 是被动语言，后面要加to do. 又，领奖是已经发生的事情，故用完成时态。
3，a 是泛指，表示一种必读书；a good knowledge of 是固定搭配。

Answer 2

D. deducing 介词后面+doing。
C.to have won 表示已经完成的事情。be reported to do sth.
A.a;a 第一空的意思是：一本必读书籍
a good knowledge of ……是固定搭配。

Answer 3

对你已经无语 叫你一道一道地问 偏要连问三道 看你等到什么时候！

Answer 4

3.D. reducing
这是现在分词做状语，

4.C.to have won
is reported to have done sth 基本上成了一个固定的句型

5.A.a;a
a must-read book必读的书；a knowledge of 固定短语

Answer 5

D 动词ing表结果状语
C 语感，被报道已经做了某事
A knowledge不可数，但a good knowledge of口语常见，前面那个a凭语感吧

Answer 6

3d 前后主谓关系 用主动 此外thus是介词 另外 题干中的put指“说”
4c be reported to have done来自于句式it is reported that 用have 是因为先发生to后面的动作 才会被report
5a knowledge不可数 但是一部分不可数名词前有形容词修饰时 就是泛指了 book是泛指一本书 一本必读书籍 所以选a
