面对茫茫作文题海，不少考生不知所措：全部话题都准备不切实际;不全面准备，心中又没底。充分准备了其中某个话题，比方说，妇女犯罪问题，并不意味着考生有把握写好另一个话题，例如垃圾问题，毕竟不同的话题要求考生具备不同的观点、词汇。怎么解决这棘手的问题呢?关键在于开阔思路，积累相关写作素材，善于从不同话题中找"共性"。我们只要对已出现的作文考题稍作分析，就可以发现，虽然雅思作文话题多达数百题，不少话题其实是类似，相近或者是相通的，例如，"远程教育的利弊"="电脑取代老师的利弊"，"谁该为我们的老人负责"="老人住老人院还是家里"，"动物园有没有必要"="该不该保护濒危动物"，"政府该不该资助艺术家"="政府该不该投资艺术项目如音乐厅、博物馆等"。笔者开玩笑说，在写作老师的眼中，动物园跟博物馆差不多，奥运会跟旅游业没啥不同，甚至养宠物跟出国留学也能扯上边!在写作过程中，我们很容易发现，支持建动物园的论据跟支持建博物馆的论据差不多，所需的词汇也相差无几;奥运会的好处跟发展旅游业的好处95%相同!下面简单列出动物园和旅游业的PROS，希望读者有所启发，发现其中奥妙。
