helen has been studying piano for several years and she still___
a,has b,does c,has been d,did
a,has b,does c,has been d,did
答案：B.
翻译：海伦几年来一直在学习钢琴,并且她（现在）仍然在（学钢琴）.
1.前句has been studying采用了现在完成进行时,该时态强调动作从过去开始,一直延续到现在,可能刚刚结束,可能现在还在进行,也可能会继续下去.
2.所以根据句意,可知第二句是指“她现在还在学钢琴”,即该句采用一般现在时即可.
四个选项都采用了省略语法.
1）A/C错误,就算后句是现在完成时的话（不能是现在完成时,否则和前句的现在完成进行时重复）,必须省略成：she has still been,排除AC；
2）B中does代指studies piano,D中的did代指studied piano.
很明显,答案为B,不能是D（D所表示的一般过去时含义已经包含在前句的现在完成进行时中,因为该时态强调动作从过去开始发生）.
