Don t hAvE to意思

不是一定要 have to have to通常指由于客观原因则不得不做某事,意思为“不得不”. e.g. It's dark now. I have to go home. 天黑了,我不得不回家. It's raining, and I have to stay at home. 外面在下雨,我不得不呆在家里. 一、have to与一般情态

"don't have to "和 "needn't "都有“没必要”的意思,二者的区别如下:1、固定搭配不同.Don't have to do sth. 例句:You don't have to pay at once.“你不需要马上进行支付.” Needn't do sth. 例句:You needn't pay at once. 此时,need

have to本身就是不得不,don't have to 是双重否定

不想拥有

mustn't 禁止 needn't 不需要 don't have to不必

原发布者:蝶梦88 must与haveto的区别区别1:must多表示主观需要或责任感的驱使有必要或有义务去做某事,多译为“必须”,而haveto多表示客观存在的环境所限,即客观要求(无奈)而为之,多译为“不得不干某事”.例:

您好,很高兴为您解答!mustn't 不许 ,命令语气 语气很强硬 needn't 不需要,没必要 表示一种建议 don't have to 同needn't didn't 一般过去式的否定,一般意义上的“没有”,是一种陈述语气 ~~~~~~~~~~~详细耐心解答,满意欢迎采纳~~~~~~~~

意思是 不必知道

你从哪里看到 haven't to 的用法?没有这种用法!have to是一个固定短语, have 是行为动词, 意思是“不得不”它的否定应为don't have to 意思是“不必要,不需要”have做助动词时,在可以在其后加not表否定,所以当表示“没有.”时,如果要用haven't的话,正规的句子应该是:I haven't got any money.(现在完成时,haven't 做助动词)作助动词还用于虚拟语气,表示与过去事实相反的假设 (假如那时)的话She might have come if she hadn't been so busy.当时若不是那么忙,她是可能来的所以 haven't后面不可能有to!!!

don't have to和needn't don't have to是 “不必须” 的意思.needn't 是“不需要”的意思 区别是:don't have to 比 needn't 更强调
