话题：
在公共场合，有许多人都不注意自己的言行，甚至有些人做出令人感到不舒服的事情，例如：随地吐痰，扔垃圾，大小便等等。这些不文明行为不仅破坏了公共环境的卫生，给周围的人带来诸多不便，而且还有可能传播细菌和疾病，因此公共场合不文明现象必须引起重视，对此，你有什么想说的。
参考例文一：
We may have experienced such an experience before: Most people always do some uncivilized things in a public places, which disgust and annoy most other people. Such as spitting, littering, peeing in public. Personally I had the embarrassing experience one late night of seeing a man peeing alongside the river. He was not embarrassed at all.
Such inappropriate public behaviors have a terrible influence on society. On the one hand, most unsanitary behavior can spread germs and diseases to the general public. On the other hand, these behaviors may lead to the pollution of the environment and show little or no consideration for the environment.
We have to take measures to improve this situation. Our government should emphasize this kind of behaviors. Our teachers should teach and enforce acceptable standards for all students. And in the home, parents should teach the children what is right by example.
参考例文二：
There is no doubt that the immoral behaviors exist in every public place. For example in Beijing subway, when you try to get a ticket, you will find a lot of people waiting in front of you, and nobody is in the line.
Immoral behaviors in public bring about a series of problems. One of the most serious things is that it may lead to a negative impact on our sense of social responsibility. We will keep ignoring other people’s rights and feelings, and in turn, we also will be disrespected someday.
To improve this phenomenon is certainly a difficult thing. But it is necessary to call people on doing appropriate things in a public places.
