You eat an apple 改为否定句是you are not eat an apple吗
改为否定句：You don't eat an apple
句子含有BE (am,is ,are)的句子,变否定为下面公式
主语+be (am,is,are)+ not +表语（形容词,名词,介词短语,从句,非谓语）
句子不含有BE (am,is ,are)的句子,变否定为下面公式
主语+don't +动词原形 +其它（主语为非三人称单数主语；时态为一般现在时态）
主语+doesn't+动词原形+其它（主语为三人称单数主语；时态为一般现在时态；）
主语+didn't +动词原形 +其它（主语为所有人称的主语；时态为一般过去时态）

you don't eat an apple

you can't eat an apple

句中如果有am/is/are时，助动词就是am/is/are。该句句中没有am/is/are, 所以不能用are作为助动词，eat体现原形，所以借助助动词do。
正确：You don't eat an apple.

原句的时态为一般现在时，所以改否定句也应该还是保持原来的时态，应该改为You don't eat an apple.
如果要用be动词的话应该是You are not eating an apple，而不是You are not eat an apple.

不是吧。。。
