　　1、B.tosomeextent在一定程度上；在某种程度上(=toacertainextent,toadegree)

　　2、A.信息：hasreturnedfrom表明后面动作应该是过去,排除B,D.后半部分duringwhichwecommunicatedwith表明所填动作也应该为一般过去.

　　3、C.cannot、、、toomuch决不会太…；怎样…也不过分；越…越好.固定结构.支持信息whichissuretoplayanimportantroleinourdailylife.再如：

　　Youcannotbetoocareful(enough).

　　4、C.beseated/dressedin/filledwith

　　beconcerned/worriedabout

　　besurprised/shocked/astonished/amazedat

　　bepuzzled/troubledby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theplan【单数】which/thatpromotes.
