推 winniebabe:我認為has been taking 有"一直"的語意，不曉得對不對 04/25 17:45
我想請問以下這題選擇題，為何不能選A呢？
選B的原因差別是在哪呢？因為A所表達的語氣也是主動對吧？
has 與 has been的差別在哪呢？因為看不出來這句的時態該怎麼界定 @_@
If they are doing fine, then the chances are their mother __________
care of them.
(A) has taken
(B) has been taking
(C) has been taken
(D) took
謝謝大家!!
