She does her homework every day 改否定句 为什么 具体点
She does her homework every day 改否定句 为什么 具体点
She doesn't do her homework everyday.
或She does not do her homework everyday.
方法:1.看所提供题目的时态.2.再看句中有没有情态动词,如果有,那就在情态动词后面直接加 not 变成否定句,如果要变成一般疑问句,那么就直接把情态动词提前即可.3.如果没有情态动词,看看有没有 be 动词,如果有,那就在 be 动词后面直接加 not 变成否定句,如果要变成一般疑问句,那么就直接把 be 动词提前即可.4.如果即没有情态动词又没有 be 动词,那么就要借助助动词,在这之前先分清每句的时态,如果是一般现在时,那么就要跟着人称进行相应的变化( do / does ),如果是过去时,只提 did 即可 ,注意,如果提出了助动词,原来的动词要变回原形.
例:1.We can go to that park with our teacher next week.
否定 句→ We can not (can't) go to that park with our teacher next week
一般疑问句 → Can you go to that park with our teacher next week?
解析:因为 can 是情态动词,所以直接在情态动词后面加 not 变为否定句,当变成一般疑问句时,只要把情态动词提前就可以了,在这道题目中,因为主语是 We ,所以在变疑问句时,要进行人称的转换.
2.She is good at dancing.
否定 句→ She is not (isn't) good at dancing.
一般疑问句 → Is she good at dancing?
解析:因为 is 是 be 动词,所以直接在 be 动词后面加 not 变为否定句,当变成一般疑问句时,只要把 be 动词提前就可以了 .
3.I wash my face every day.
否定 句→ I don't wash my face every day.
一般疑问句 → Do you wash your face every day?
解析:因为这道题中即没有情态动词又没有 be 动词,那么就要借助助动词,看到了 wash 和 every day ,知道是一般现在时,主语是 I ,所以借助助动词 do ,再在助动词后面加 not 变为否定句,变成一般疑问句时,把助动词提前,但是原来的动词要变回原形.第一人称和第三人称复数借助助动词 do .
4.He plays football on the playground after dinner every day.
否定 句→ He does not (doesn't) play football on the playground every day.
一般疑问句 → Does he play football on the playground every day?
解析:因为这道题中即没有情态动词又没有 be 动词,那么就要借助助动词,看到了 plays 和 every day ,知道是一般现在时,主语是 he ,所以借助助动词 does ,再在助动词后面加 not 变为否定句,变成一般疑问句时,把助动词提前,但是原来的动词 plays 要变回原形 play .第三人称单数借助助动词 does .
