Your后面怎么一下用is一下可以用are?请你帮忙指点一下??

Never use if your eye is injured, you aretemporarily blindedThe problem with your eyes is that they play tricks on you, irritated or infected. During that split second that your eyes are closed. 是什么原因呢?

不会吧,你的意思your用is.you用are.那怎么有很多句子your lips is so beautiful and that your dress are also very pretty!During that split second that your eyes are closed, you aretemporarily blinded.名词复数可以用are你看!

前者 主语是 The problem 所以用is 。 with your eyes是定语

后者 从句中的 主语是 your eyes所以 用are

后面的名词是复数用are，单数用is 这几句翻译完全是用机器翻译的，不符合语法，不过大致意思对。
