面對茫茫作文題海，不少考生不知所措：全部話題都準備不切實際；不全面準備，心中又沒底。充分準備了其中某個話題，比方說，婦女犯罪問題，并不意味著考生有把握寫好另一個話題，例如垃圾問題，畢竟不同的話題要求考生具備不同的觀點、詞匯。怎么解決這棘手的問題呢？關鍵在于開闊思路，積累相關寫作素材，善于從不同話題中找"共性"。我們只要對已出現的作文考題稍作分析，就可以發現，雖然雅思作文話題多達數百題，不少話題其實是類似，相近或者是相通的，例如，"遠程教育的利弊"="電腦取代老師的利弊"，"誰該為我們的老人負責"="老人住老人院還是家里"，"動物園有沒有必要"="該不該保護瀕危動物"，"政府該不該資助藝術家"="政府該不該投資藝術項目如音樂廳、博物館等"。筆者開玩笑說，在寫作老師的眼中，動物園跟博物館差不多，奧運會跟旅游業沒啥不同，甚至養寵物跟出國留學也能扯上邊！在寫作過程中，我們很容易發現，支持建動物園的論據跟支持建博物館的論據差不多，所需的詞匯也相差無幾；奧運會的好處跟發展旅游業的好處95%相同！下面簡單列出動物園和旅游業的PROS，希望讀者有所啟發，發現其中奧妙。
