Answer 1

都是瞎推荐，哎。
更正被推荐答案第一题！

1. D
one是a habit的同位语，而后面的you can learn even at an early age为省略关系代词that的定语从句。
其中关系代词that代替先行词one，在定语从句中充当learn的宾语，所以可以省略。
2. B
逗号前后部分主语不同，但是之间又没有连词and等引导，说明后面部分是独立主格结构。
考查独立主语the most recent (unmanned spacecraft)和非谓语动词launch之间为被动关系，且launch该动作已经发生，所以用having been done结构。
3. D
前面有I'm sorry，所以用That's all right回答，其意思是“没关系”。
4. A
此题考查状语从句的省略，即：
whether written or not = whether (office rules are) written or not
很明显被省略的主语office rules和write之间为被动关系，所以用其过去分词。
5. A
选项做句子主语，所以用动名词或不定式结构，排除B；
句意明显为被动，排除主动结构的CD。
A为动名词的被动结构，做该句的主语。

Answer 2

1、C 这是一句话若选AD则一句话有两个谓语，that从句前一般不加逗号
2、B 由于前面已有谓语，所以此处考察非谓语，AC错误；由于事情已经发生，所以用B；不定式表示将要发生
3、D 对话中常用语
4、A
5、B 被暴露在阳光下

Answer 3

1.D 引导同位语从句
2.A
3.D
