We don't have the same looks.也要加s呢？look做动词时要s吗？做名词时要s吗？look有看，瞧. 相貌样子的意思.那么个什么时候，什么情况要加s？详细一点解释，好的再加悬赏！
为什么？We don't have the same looks.而but you don't have the same look.怎么这两句一个有s一个没加s？难道“你们”.“我们”也有区分？谁能讲明白些？
额那么You are brother and sister,but you don't have the same look.这是原句.
追答那就只能这样解释了
因为相貌不同，所以有两张不一样的面孔，所以加了s
但相貌相同，那看起来就是同一张面孔，只有一张面孔，所以就不加了
那么什么时候的第三人称的句子里要加s?
追答在一般现在时的句子里，且作动词时，比如
He looks like his mother.
但在强调句型中例外，因为有助动词，比如
He does look like his mother
在疑问句中有助动词也不需要
Does he look like his mother?
应该差不多了把
作为名词时 当相貌讲，常常用复数形式，后面加s. She has lost her good looks.追问
那做疑问句呢？如What does she look like ?怎么不用？
还有照上面那句回答怎么回答？
does 是一个助动词，常常用于第三人称的疑问句中。有了它，谓动词就不需要加s了。
如：He goes to school every day.----- Does he go to school every day?
he looks like his father.
还有你补充的问题，you 是指的你一个人，而不是你们。
那么什么时候的第三人称才要加s？
追答你很执著。第三人称单数，一般现在时，用于肯定句，在单词后面加s.
用于否定和疑问句，需要助动词来帮助构成疑问和否定时，用does, 后面动词用原型。
He goes to school every day.
----- Does he go to school every day?
——he doesn't go to school every day.
