Two heads are better than one 直译是两个头脑比一个强，其实就是汉语里的人多智广或人多力量大的意思。

例句

I can help you to have this presentation ready tomorrow morning. Let's work together. Two heads are better than one.

My sister and I discussed lots of ideas to make mum's party a success. Two heads are better than one.

请注意

如果你形容两个人或两个团队是 head-to-head, 意思就是双方势均力敌，不相上下。

Student rowers in the north-east of England are preparing to go head-to-head in the annual university boat race on the river Tyne.
