When I went to school they asked me what I wanted to be when I grew up .I wrote down 'happy'.They told me I didn't understand the assignment ,and I told them they didn't understand life.
and do you understand?

Answer 1

过多的翻译我就不写了，楼上的回答已经很到位，我想关键的还是assignment这个词，在这里这句话可以这么理解：他们嘲笑（应该有这么点成分，但我想不出更好的词了）我没有远见，但我认为他们不懂得生活的意义。
不过说到生活、或者说生命的意义，列侬确实是一个热爱生活的人，他一直想用音乐来表达对于生活的热爱，可惜，披头士透支了自己的才华，结果曲终人散。很悲哀的一件事。

Answer 2

从我5岁开始，我的妈妈就一直告诉我 快乐是生活的关键
当我上学之后 他们问我 长大之后想成为什么样的人 我写下“快乐的人” 他们告诉我 我没有理解作业的要求 可是我告诉他们 那是他们不懂得生活
希望能帮到你

Answer 3

当我5岁的时候，我的妈妈经常告诉我快乐是生活的钥匙
当我走进学校他们问我将来长大要做什么。我写下“快乐”二字。他们告诉我我不明白作业，我也告诉他们他们不懂得生活。
你懂得吗？
