Question

【题目】By the end of last month, we _________ twelve English story books.

A. have readB. had readC. were readingD. are reading

Answer 1

【答案】B

【解析】

句意：到上个月底，我们已经读了十二本英语故事书。A. have read现在完成时；B. had read过去完成时；C. were reading过去进行时；D. are reading现在进行时。根据时间状语By the end of last month判断用过去完成时，构成是：had+动词的过去分词，此空故填have read。
