same shapes。改成一般疑问句 They have

一般疑问句：Do they have the same shapes?

将陈述句变成一般疑问句的方法就是：就是将助动词或者情态动词提至句首，第一人称要转换成第二人称，另外要注意根据时态选用合适的助动词或者情态动词，在疑问句中谓语动词要也要处于合适的状态。

例如：

I like peach.→Do you like peach?

She went there.→ Did she go there?

They have never met each other before.→ Have they met each other before?

We can make it.→Can you make it?
