Don't hAvE to 和nEED't的区别

"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为...

两者意思相近,很多情况下可互换,常用于"同义句"转换. need not:可以是主观或克观上的"不需要","不必要";do not have to:强调客观上的"不需要","不必要" .

这个只要理解了就很好区别。 needn't = need not. 这里的need是情态动词。表示“没必要做……”,一般用作对用MUST提问的疑问句的否定中。 比如说: Must I clean the room? 我必须清扫房间吗? No, you needn't. 不,你不必。 don't need =do not n...

第一指主观认为的不需要, 第二指客观事实上的不需要, 第三有”Must“开头的一般疑问句的否定回答。 望采纳。

词汇分析 need not to do中need是情态动词 需要做;通常用于疑问句、否定句、条件句、 whether(if) 名词从句或含否定意义的句子中。 don't need to中need是实意动词 必须; 不得不; 词汇分析 need 情态动词 1.Give it directly to him; there is n...

一个是情态动词,一个是动词。 eg. 1. must i clean the room ?我必须清理房间么? No, you need't.不,你不需要。 2. i have one.i needn't it.我有一个了,我不需要它了。. don't need还可以表示为dosen't need, didn't need.更具情况而定。基...

need not do 的need是情态动词 没有数和时的变化 后接动词原形 否定直接加notdon't need todo 的need是行为动词 具有三单及时态的变化 否定前加助动词 do

needn't have done从用法上,是情态动词,didn't need to do是实义动词。 从意义上,needn't have done暗示已经做了,有“本不需要”的意思,didn't need to do暗示还没有做,就是纯粹地“不需要”。前者是过去将来时,后者是过去完成时。 具体区别...

don't need to do 与needn't do 有什么区别? 有一定的区别: don't need to do 这里need是个行为动词,而needn't中的need是情态动词; needn't应该相当于don't have to 更好 还有needn't 是否只能用于一般现在时? 是的,一般只用于一般现在时...

need有两种用法,一种是情态动词(need do)一种是实义动词(need to do) 那么当情态动词时否定就是needn't do实义动词时就是don't need to do 举个例子: 你不需要上学. 第一种:You needn't go to school 第二种:You don't need to go to sch...
