When talking about the hero, people will think about the person who saves the world, such as superman and batman, they care about the public's lives and interest all the time. In the real life, people believe that a hero at least can make great influence to the society, like the scientist. But in my opinion, some true heroes are easy ignored, they are doing the ordinary jobs while making great contribution to the society. The city cleaners are the classic ones, they beautify the city and bring comfort to the public. Though they are nobody, they are doing the great job. They are heroes and should be praised.
当谈到英雄时，人们会想到超人、蝙蝠侠等拯救世界的人，他们时刻关心着公众的生活和利益。在现实生活中，人们相信一个英雄至少能像科学家一样对社会产生重大影响。但在我看来，一些真正的英雄很容易被忽视，他们在做平凡的工作的同时，为社会做出了巨大的贡献。城市清洁工是典型的清洁工，他们美化城市，给公众带来舒适。虽然他们不是什么人，但他们做得很好。他们是英雄，应该受到赞扬。
