填空题on business[听力原文]People visit other countries for many reasons. Some travel on business; others travel to visit interesting places. Whenever you go, for whatever reason, it is important to be safe. A tourist can draw a lot of attention from local people. Although most of the people you meet are friendly and welcoming, sometimes there are dangers. For example, your money or passport might be stolen. Just as in your home country, do not expect everyone you meet to be friendly and helpful. It is important to prepare your trip in advance, and always be careful while you are traveling.[解析] 录音开头提到，人们去国外的理由有很多，故可以推测得知空格内填入的是去国外的理由之一。根据录音可知答案为on business。
