同义句转换：Diving was not an olympic sport in the past ,but it is now
Diving has　（　　）（　　）been an olympic sport

1 only recently /
2 at last
再问： not always 可以吗//
再答： not always ------可能包括“过去”，也可能包括“现在”，语义不太确切。
再问：哦，书上是这么写的我不知道为什么要改为：not always 可以给我说一下原因吗
再答： ok . 书上的意思就是：以前不是的（属於一个长的时间范围），但现在是了（相比以前的长时间，现在成为olympic sport的时间还是太短）。说不定过几年又不是olympic sport了。在我看来， 1 only recently / 2 at last 是比较可信的答案。呵呵。
