问题描述：

There used to be some big trees by the lake, ___________? 怎么变反义疑问句?
只有一种变法吗？可以用weren't there吗？

答

usedn't there 和didn't there 都行。一般都习惯用后者。

答

didn't there?
不可以用weren't there。

答

didn't there 或usedn't there

答

这是一个There be的句型，used to do是表示过去常常做某事，现在不做了。具体到这个句子，那么do就变成了be动词的原形be,
反义疑问句应该是weren't there?
