要怎么样才要在动词的后面加S啊?
翻译:Unless he gets up early,he can nor bo here on time
有的为难大家了,好的话加分,你会回答多少个就多少个!

一:didn't 是用于过去事态的,如果事情发生在过去,就用didn't.例如:He did't come here yesterday.这时,无论单复都是didn't
二:don't 是用于第1人称,第2人称(1,2无论单复都是don't)和第3人称复数和其他复数.例如:I don't kown what you are saying.
三:doesn't是用于第3人称单数和非人称单数.例如;They don't like eat apples.他们是第3人称复数.
二三都是用于现在时态.
当主语为单数时,并且这个句子是现在时.在句子后加S.
翻译:除非他早起,否则他不能按时到这里.
PS;都是我自己写的,尽可能易懂了.嘿嘿

第三人称单数现在时后面的动词要加“s”。当然有第三人称复数了,就是他们,她们或它们。
翻译:unless he gets up early,he can not be here on time.
除非他不睡懒觉,他是不会及时赶到的。

那只是时态的区别,现在时第一二人称及复数用DONT,第三人称用DOESN`T
过去时都用DIDN`T
他们是复数现在时用DON`T 过去时也是DIDN`T
当主语为第三人称单数时,一般情况下的动词加-s.特殊情况加-es或不规则变化

除非他早起,否则他就不能及时赶到这了...

对过去的否定用didn't
对现在的第一二人称和复数形式用don't.第三人称单数用doesn't
他们是第三人称复数,故用don't
当主语为第三人称单数时,一般情况下的动词加-s.特殊情况加-es或不规则变化
除非他早点起床,否则他不能准时到这儿

助动词do+ not 构成否定句,don't是一般现在时,didn't是过去时,doesn't用于一般现在时的第三人称单数。
例如:
一般现在时: I do not want to be criticized. 我不想挨批评。
过去时: He doesn't like to study. 他不想学习。
第三人称单数: In the past, man...

例如:
一般现在时: I do not want to be criticized. 我不想挨批评。
过去时: He doesn't like to study. 他不想学习。
第三人称单数: In the past, many students did not know the importance of English. 过去,好多学生不知道英语的重要性。
你不......应该:如果是一般现在时就用don't,过去时就用didn't。
有第三人称复数,也要看时态,如果是一般现在时就用don't,过去时就用didn't。
记住只有第三人称单数用doesn't。
“他们”是第三人称复数。
在一般现在时中,当主语是第三人称单数时,谓语动词要用第三人称单数形式,即常在动词原形后加-s或-es。
一、人称代词he, she, it是第三人称单数。
二、单个人名、地名或称呼作主语;是第三人称单数。
三、单数可数名词或"this / that / the+单数可数名词"作主语时,是第三人称单数。
四、不定代词someone, somebody, nobody, everything, something等及指示代词this, that作主语时,是第三人称单数。
五、不可数名词作主语时为第三人称单数。
六、当数字或字母作主语时,看作第三人称单数。
Unless he gets up early,he can nor bo here on time ?
翻译:除非他早起,否则不可能准时到达这里对吗?
别着急,慢慢学习,你会看到成果!^_^

didn't是在过去式使用
比如,He didn't like it at all
表面看是“他一点也不喜欢它”,其中却暗含一个意思是他不喜欢他,是以前的事,不一定现在也那么不喜欢
don't是一般现在式
比如,I don't like you
就直接是,我不喜欢你
这种状态就是现在
doesn't是指第三人称单数形式
第三人称就包括...

doesn't是指第三人称单数形式
第三人称就包括他,它,她,还有他们,她们,它们
而第三人称复数就是他们,她们,它们
‘你不...'是应该用don't
因为你是第二人称
所以你刚刚说的‘他们’就是第三人称复数
从你的叙述来看应该是个初学者
所以复杂的先放一边
要在动词后加S的
要得是在一般现在式的第三人称单数的情况下
翻译:除非他早起,他才可以按时到达那儿
