题目：Nowadays, international tourism is the biggest industry in the world. Unfortunately, some people argue that international tourism creates problems rather than benefits. Do you agree or disagree?
这道题是要分析国际旅游业发展的好坏，因此考生可以从好的方面（如促进经济发展，文化交流）和坏的方面（如造成环境污染，打扰当地居民生活）等方面来展开论述。考官提供的范文在这道题目中更倾向于旅游业的发展是有利的，所以反对方就是承认旅游业存在的问题并给出反驳，写法如下：
Tourism seems to have some disadvantages too.（主旨句：旅游业的发展也有一些问题） Many people believe that tourism can destroy or spoil visited locations, such as pollution and littering.（反对方观点：造成环境污染和垃圾遍地） People can adhere to their own beliefs and way of life if they want to; no one can really forcefully manipulate someone to change from their morals and ethics（展开论证：人们有权利选择自己的信仰和行为方式，没有人可以改变别人的道德修养）. However I believe the problems caused by tourism are not something that cannot be solved or prevented.（反驳反对方的这种观点：但是旅游业所造成的问题是可以被解决和阻止的） Pollution can be avoided by increasing usage of environmentally friendly vehicles used for tours and rents, warnings and visual education on littering and smoking; specific times can be allocated for tours to certain areas, such as peak times, where local inhabitants feel uncomfortable due to too many foreigners.（反驳的论证：举例如何治理环境污染和安排相应的时间和场地专供旅游而避免打扰当地人的生活等）
