合作伙伴的英文：Partner。加"s"和不加"s"的区别？

一般是：
1个就是单数 不加s
2个以上就加s

就这么简单

你是我的合作伙伴
You are my partner.

我们是合作伙伴
We are partner（单只我和你）/partners(多人).

partner 翻译：

1.作为名词n. ：伙伴；合伙人；配偶

2.作为不及物动词vi. ：合伙；合股；成为搭档

2.作为及物动词vt. ：使合作；与…合伙

如果是一个伙伴的话，用Partner
如果是两个或者两个以上的话，用partners
你是我的合作伙伴：You are my partner.
我们是合作伙伴：We are partners.
单独用伙伴这个词，就是partner

希望采纳

单数用partner复数用partners。。。
