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.
