请问,是When is it open?还是When does it open?
它们的答句都是It's open from 8a.m to 9p.m.
其中一句问句是When is it open?这是书上的问句.
还有一句问句是When does the library open?这是试卷上的问句.
请问这两个问句有什么不同?为什么一个要用be动词,一个要用助动词?

你好,同学：

这两个句子都是正确的,第一个open是形容词,放在be动词后面,构成系表结构；第二个open是实义动词,开放的意思,所以变成问句时用助动词does,这两个句子的意思是一样的,都是问：“它什么时候开放?”

希望能帮到你,祝更上一层楼O(∩_∩)O
