为什么改后的句子is还在?不是应该借助助动词does吗?2、what time is your school over?和what time does your school begin?这两个句子中为什么一个用is 一个用are?

因为is没有在划线部分内.
第一句中因为over是一个形容词,所以要用is,否则这句话就缺少动词了.
第二句里begin是动词,因为一句简单句里只能有一个动词,所以要借助助动词does.
祝你学习顺利!

1 原句有is 而且OVER 是副词，故不能省去IS
what time is your school over?
2 BEGIN 是实义动词，变问句要加助动词does （ 一般现在时主语三单）
what time does your school begin ?
注： 只有这义动词作谓语才借助助动词
