You must obey the traffic rules.If you the rules,it'll be dangerous.

问题描述:

You must obey the traffic rules.If you the rules,it'll be dangerous.
A.not obey B.obey C.disobey D.to obey
为什么要用disobey A不可以么

dis是一个具有否定意义的前缀.根据句意,“你必须遵守交通规则.如果你———,就会有危险”,很显然,应该填上“不遵守”,即“违反”,故而选disobey.那为什么不能用 not obey 呢not obey?这样的话,就缺少助力动词了,应该说“don't obey“。~~~~(>_
