Topic 1: What can you do can’t you do in some public places in your towncity country ? Public places are ones where there are a lot of people. So we should observe the rules here. Firstly, we must not smoke. It is the fact that smoking is harmful and may cause lung cancer. Moreover, the fact that you smoke in public places not only influences yourself but also everyone. So, if you are an understanding person, you should be more selfconscious in these places. Secondly, We should not throw rubbish way. If each of us litters a small piece of waste paper, the whole areasite will become quite dirty. That action makes (surrounding )environment around polluted. Now we can see waste bins everywhere so we should put rubbishunnecessary stuff into them. Last but not least, at several public sites like libraries, hospitals, or on public means of transports, we shouldn’t use phones or speak out loudly. Ringtones of coming calls can distract everyone’s attention. Or loud talks will make everyone feel unpleasant and we will become impolite people. In short, public places aren’t our own world. So we had better be polite, observant and should learn these rules of conduct to become more perfect.
