答案:D
翻译:在上个月末,他们完成了30%的生产计划.
解析:
1 由于时间是在上个月末,是过去时间,所以排除AB.
2 一般过去时态是指“在过去某个时间发生的动作或存在的状态,通常与表示过去的时间状语,如yesterday,last night等连用”.这里的 At the end of last month是过去时间,所以只要用一般过去时态.
3 过去完成时(past perfect)表示:在过去某一时间或动作之前已经发生或完成了的动作或状态,它表示句子中描述的动作发生在“过去的过去”.比如:We had learned over two thousand English words by the end of last term.
4 如题目的at the end of 改成了 by the end of,正确答案就选C.
