Dolphins are social animals.Many of them even (1)____ around human.In addition to being playful,they are hulpful to men.For example,(2)____400 B.C.the Greek poet Arion was saved from drowning by a dolphin.
(1) A.go in for to be B.are used to be C.enjoy being D.fond of being
(2) A.as far as B.as long as C.as soon as D.as early as
为什么第二题不能选D呢?
到公元前400年和早在公元前400年好像没什么具体的区别啊.

as far as 意思是远在公元前400年,
as early as  没有这种固定搭配

(1)根据题意知道,这是用固定搭配 enjoy doing sth.
(2)要看题目,前面的”For example“是“例如”的意思,如果是填”早在公元前400年“就会显得不通顺,也不大符合文章的意思。
