Question

【题目】 For many years, people __________ electric cars. However, making them has been more difficult than predicted.

A. had dreamed of B. have dreamed of

C. dreamed of D. dream of

Answer 1

【答案】B

【解析】句意:多年以来，人们都梦想着电力汽车的出现。但是，制造电力汽车比预想的要更加困难。根据时间状语For many years可知句子时态为完成时态,故排除C项和D项；句子并没有过去的时间或过去的动作，因此不存在“过去的过去”，排除A项。故答案为B项。
