There are many different taboos (禁忌) around the world. A taboo is a social action that is not 41 (allow). Almost every culture in the world has 42 (it) own taboos. When you meet people from different cultures, it is important 43 (understand) what you can and cannot do. If we are not aware 44 these differences, some unusual 45 (thing) might happen. For instance, in China, it 46 (be) rude to put the chopsticks into a bowl of rice straightly as it is often done for the dead. If you visit Nepal, you will find Nepalese often greet each other with the hands pressed together instead of shaking hands, 47 in North America and the UK, people greet one another by 48 (shake) hands. If you will do business with a South American, it seems 49 (impolitely) to be dressed in the light colors. What about Japanese? They dislike the lotus and 50 not give it as a gift to Japanese because they regard it as the mourning flower (丧花). While these different customs might seem strange to you， remember that what you consider normal probably seems just as unusual to others.
