Question

【题目】–I remember there _____ a lot of fish in Yanglan Lake. Now it has been polluted.

--What a pity! I think we should play a role in protecting the environment.

A. are used to have B. are used to be

C. used to have D. used to be

Answer 1

【答案】D

【解析】句意：——我记得过去曾经在洋澜湖有很多鱼。现在它已经被污染了。——太可惜了！我认为我们应该在保护环境方面起作用。根据句意可知这里应是指过去，故用短语used to过去常常。There be句型表示某地或某时存在某人或某物，have表示某人或某物拥有；根据in Yanglan Lake可知此处表示在洋澜湖有某物，故用there be句型。故选D。
