People are sent into our lives to teach us things that we need to learn about ourselves.
人们来到我们的生活中，是为了教我们认知自我。
语言点：注释：be sent into为被动语态，to teach us things在此处to表示目的，意为：为了，that we need to learn about ourselves为定语从句，修饰限定先行词things, need to learn about ourselves在此处need为实义动词，用法为need to do sth.或need do sth.
