题目内容

2．They__________on the program for almost one week before I joined them，and now we ________on it as no good results have come out so far．（　　）

	A．	had been working； are still working
	B．	had worked； were still working
	C．	have been working； have worked
	D．	have worked； are still working

分析在我加入之前他们已经致力于这个项目近一周，现在我们仍然专注于这个项目，因为到目前为止还没有好的结构．

解答答案是A．
本题考查动词时态；过去完成进行时强调"过去的过去"和"一直在进行"，题干中"joined them"之前"work on持续进行一周"，是过去的过去，故用过去完成进行时；由and后的now判断第二句用现在进行时，答案选A．

点评对时态的选择，要在把握时态的基本用法的基础上，根据具体语境和题干中的时间推断时态，同时关注特殊的结构．
