有不会的可以再问我:）

肯定句变一般疑问句，规律是把be动词提前，即：is there a bird in the tree? 而一般疑问句的回答要用yes或no来回答，即：no,there isn't. 而介词on在和tree连用的时候表示的是长在树上的，in则表示后飞到树上或附着在树上的，所以用the bird in the tree是正确的。

Is there a bird in the tree? Yes, there is./No, there isn't.

My brother is a nurse. （Is your brother a nurse ?Yes,he is. No,he isn't.） My father likes running.(Dose your father like running? Yes,he does. No,he doesn't.) I am a student.(Are you a student ?Yes,I am . No,I'm not . )

直接将is提前至句首即可。 Is there a bird in the tree? Yes， there is。 No，there isn't。 希望帮到你！
