you eat an apple 改为否定句是you are not eat an apple吗
you eat an apple 改为否定句是you are not eat an apple吗
you eat an apple 改为否定句是you are not eat an apple吗
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。。。
