问题描述:

Everyone must dress up.If you ____,you can't go in.为什么用don't而不用won't

if 当如果时,主句用将来时,从句用一般现在时
if 后边的句子是从句哦·····
主句是 You can't go in
所以用一般现在时,don't主句不是将来时啊因为是情态动词~我给你改改If you don't dress up,you will not be allowed to go in这样就可以咯·看出来没?原句不是can't么是呀··因为可以更改为你的要主将从现···意思是一样的··你不能进入,就是你不被允许进入~~希望帮助你理解用的
