----Have they finished the project?
---- Yes. By the end of last month, they ______ it. Now they ______ on a new one.

A．had finished; are working	B．had finished; work
C．have finished; are working	D．have finished; work

答案

A

解析

试题分析：考查时态，第一空时间是By the end of last month，by+过去时间，要和过去完成时连用，第二空时间是now，用现在进行时，句意：--他们的计划完成了吗？--是，到上个月底为止，他们已经完成了。现在正从事新的计划。选A。
点评：试题的考查要根据上下文的语境和句子中的关键词。本题就是根据上下文的语境来进行辨析的。这道题目有明显的时间，就比较好做。
