----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

Answer 1

A

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。
