阅读下面短文,掌握其大意,然后从1-10各题所给的A.B.C.和D四个选项中,选出最佳选项。
We all know that some things are obviously right. For example, it is right to be   1  to other people. It is also right to look after the environment. Some things are   2  wrong, too. For instance, we should not hurt or bully(欺负)others, nor should we litter. Rules often tell us what is right or wrong.
Rules can help the public make the right   3 , and remain safe. Car drivers have to obey traffic regulations that tell them the right things to do on the road to avoid crashes. Cyclists who give signals before turning or stopping help prevent   4 .
If people follow rules without taking other matters into consideration, it will be   5 for them to form what is sometimes called a “black and white” view (黑白分明的观点). For example, they may believe that people should always tell the truth, and that lying is   6  acceptable. Such people always stick to their views, even if it means that they may get into  7 .
Sometimes it may not be so easy to know   8  what is right or wrong. Some people choose not to eat meat because they believe that it is   9  to eat animals, but others argue that they can eat meat and   10  be kind to animals; some insist that stealing is always wrong, but others think that one does not need to feel so guilty (有罪的) when stealing some food to eat, if he lives in a really poor area and he is starving.
Rules help us live together in harmony, because they show us the right way to treat others. However, some people argue that rules may be confusing, having observed that rules change all the time, and that some schools have some regulations and others have different ones---so who is to decide what is right?
