如何乐观地生活 how to be positive about life

Last night, I watched a movie, it is about two teenagers, they have cancer, but the boy is positive about life while the girl is negative about life. They meet each other, then the girl is affected by the boy, she starts to see the beautiful things in her life. I am so moved by the movie, though the ending of the movie is not so perfect, we see the change of the girl’s life. The topic of the movie is to tell people to be positive about life, no matter what happens, even the bad fortune they get, they still need to smile every day. People need to find the beauty of life, so they won’t life live without meaning.
昨晚，我看了一部电影，那是关于两个青少年，他们身患癌症，但是男孩对生活很乐观，然而女孩子却对生活很悲观。他们遇见了彼此，然后女孩受到了男孩子的影响，她开始看到了生活的美好食物。我被这部电影深深地感动，虽然电影的结局不是那么的完美，但是我们看到了女孩生活的改变。电影的主题是告诉人们要对生活乐观，无论发生什么事情，即使他们遇到不幸，仍然需要每天乐观面对生活。人们需要发现生活的美，这样他们就不会活得没有意义。
