答案

1、B .to some extent 在一定程度上；在某种程度上(=to a certain extent,to a degree)
2、A.信息：has returned from 表明后面动作应该是过去,排除B,D.后半部分during which we communicated with 表明所填动作也应该为一般过去.
3、C.cannot、、、too much 决不会太…；怎样…也不过分；越…越好.固定结构.支持信息which is sure to play an important role in our daily life.再如：
You cannot be too careful (enough).
4、C.be seated/dressed in/ filled with
be concerned/worried about
be surprised/shocked/astonished/amazed at
be puzzled/troubled by 等结构,作状语时,省去be,直接用过去分词（实质是过去分词演变的形容词作状语）.
5、C.only,只是,仅仅.位于句首,后面接三种形式要用到装：副词,介词短语,状语从句.
6、C.句意：——在全国普及图书馆的计划明年会落实吗?——说不定,我想.
promoting作后置定语.用定语从句则应该是 the plan【单数】 which/that promotes.
