mike+has+some+black+shirts改为否定句?
一、解析
首先否定句是Mike does not have any black shirts.然后does not也可以缩写为doesn't,即Mike doesn't have any black shirts.(迈克没有黑色的衬衫。)
因为根据has判断句子是一般现在时,并且主语是第三人称单数,所以否定句在实意动词has前面加入助动词does not或者缩写为doesn't,实意动词还原为have,some在否定句中要变成any,所以否定句是Mike does not have any black shirts.
二、拓展——变句思路
(1)有 be ,be后面加 not
例一: He is my uncle .(他是我的叔叔)
这句话里面有be 动词 is,否定句在 be 动词 is 后面加not,is not 可以完整写,也可以缩写为 isn't
即 否定句:He is not / isn't my uncle .(他不是我的叔叔。)
(2) 有 can,can后面加 not
例二: She can dance .(她会跳舞,)
这句话里面有情态动词 can,所以否定句在can 后面加 not ,can not 可以完整写,也可以缩写为 can't
即 否定句:She can not / can't dance .(她不会跳舞。)
(3)无 be 无 can找实意动词,前面加don't 或 doesn't,此时动词需要还原
例三: She wants to go to the park .(她想要去公园。)
这句话 dances判断句子一般现在时,并且第三人称单数,所以实意动词 wants 前面加入找动词 doesn’t ,动词还原为want
即 She doesn't want to go to the park.
(4) and 变成 or,some 变成 any 。
三、拓展训练
1 I am a student.
否定句:I am not a student.
2 She likes cats.
否定句:She doesn't / does not like cats.
Mike doesn't have any black shirts .
迈克没有任何黑色的衬衫 。
( 如上句子 ,已经修改为了否定句句子的形式 。)
在美国英语中借助于does+not,即:
Mike doesn't have any black shirts.
行为动词作谓语,一般现在时态主语是第三人称单数形式变否定句,直接在主语后加注动词doesn't,原来的动词要还原。some改为 any
