【答案解析】[参考范文]： In the picture above, two citizens are visiting a park that is honored with the World Civilization Heritage. Unfortunately, neither of them pays attention to his behavior, for one of them is dropping a cigarette end to the ground, while the other is carving his name into a wall to mark his visit. Simple as the picture is, it does highlight a focal point, that is, some travelers tend to overlook the fact that good manners are central in a civilized society. As a result, their improper behaviors not only damage the public amenities but also bring ill image to themselves. Still, a citizen is also a mirror of his nation: his behavior best speaks for the civilization of his country. In this sense, his bad manners also bring ill image to his native country as well. It is important for a country to take concrete measures. First, the press is expected to step up the efforts, emphasizing the importance of good manners. Second, a monitoring mechanism must be built up so that such behaviors can be spotted immediately and punished accordingly so that other individuals would not follow suit. Still, citizens are supposed to enhance their awareness that good manners are not only necessary, but also indispensable to the development of a civilization. Only in this way can we enjoy more individual happiness in an increasingly civilized world.
