Be careful,or you will hurt yourself.同义句转换
If you don't careful,you will hurt yourself转换的对吗,是用don't还是用aren’t careful ,don
't和aren't总是不知怎么用
答
不对吧应该是be careful
答
If you aren't careful, you will hurt yourself.
因为careful 是形容词，前用系动词，be careful 小心
don't +行为动词，如：Don't touch that knife.
答
If you don't be careful,you will hurt yourself
You will hurt yourself ,unless you are careful
careful 是形容词,要与be动词连用
don't是助动词,后面接原形动词,不能直接加形容词
答
If you aren't careful,you will hurt yourself.
