在英文中，可以用 "I will make people happy" 来表示 "我会让人们幸福" 的意思。这句话的来源是由英文动词 "make" 和形容词 "happy" 组成。

"Make" 是一个常用的动词，意思是 "使，制造，导致" 等。例如：

I will make dinner for my family tonight. (我今晚会为我的家人做晚餐。)
The noise made me wake up. (噪声使我醒来。)

"Happy" 是一个形容词，意思是 "快乐的，幸福的" 等。例如：

She is a very happy person. (她是一个非常快乐的人。)
The news made him very happy. (这个消息使他非常高兴。)

所以，当 "make" 和 "happy" 结合在一起时，就可以表示 "使（某人）快乐" 的意思。因此，"I will make people happy" 就可以表示 "我会让人们幸福" 的意思。

下面是一些例句：

I will make my friends happy by organizing a surprise party for them. (我会通过为朋友们组织一个惊喜派对来让他们感到高兴。)
