Footprints Only
Protecting the environment is a basic public consciousness in the U.S Street cleaners benefit from this consciousness; often, they needn`t clean up the "battle field" after a big assembly.
I was in Washington D.C. over Independence Day and thousands of people went to see the parade in the early morning.
That day must have been one of the hottest Inexperienced in Washington. Street vendors were doing a brisk business in drink sales. Almost everyone held a bottle of Coke or some ice cream.
After the parade ended and people left, I couldn’t find any empty cans or wrappers .People left, I couldn’t find any empty cans or wrappers .People left only their footprints.
In Washington, aside from the buildings and roads, almost every inch of land is covered with lush lawn. You can step on the lawns ,too.
There are even signs which say:” You are welcome to sit here.” So people do lots of things on the lawns ,such as walking, playing ball ,holding parties, and so forth.
These lawns have become important places in the daily lives of Americans .Even though you can run ,jump, sit ,lie of even roll on the grass ,however, you can’t pollute it with litter.
What would happen if some one were to dispose litter in a public place ?"It would stir public anger and denouncement,” Sonia said.” people would look at you strangely as if you an alien from outer space.
At the same time, someone would quietly pick it up for .who wouldn’t be embarrassed by such a scene?

只留下脚印
保护环境是美国基本的公民意思.得益于这种意识,美国的清洁工人用不着大型集会后清理“战场“。
我在华盛顿时正逢美国国庆日，上午，成千上万的人涌上街头观看游行队伍。那天恐怕是华盛顿最热的日子，路边冷饮摊车的生意红火得很，大人孩子几乎人手一瓶可乐或冰激淋。当游行结束人们散去，地面上却见不到空可乐罐或纸包装。它们的归宿是路边的垃圾箱。那些一时没有找到垃圾箱的人，就一直将空盒捏在手里。人去街空，留下的只有脚印。
华盛顿的草坪极多，除了道路和建筑物，几乎都被草坪覆盖着。草坪不怕人们“践踏 ” ，有的甚至还立起“欢迎你与青草同坐”的牌子。因此，人们的户外活动，散步、打球、聚会场 ，都在草坪上进行，它已成为人们生活中一个重要场所。不过，尽管你可以在草坪上跑啊，跳啊，坐着，躺着，乃至打滚，却不可以用废弃物污染它。
如果有人在公共场所公然乱扔废物，会怎样呢。？索妮娅说会引起公愤，招来谴责。人们会用奇怪的目光看着你，仿佛你是个天外来客，而且会有人默默地替你拾起。如果置身地那场景，谁能不感到尴尬呢？
