在上一篇文章中，第二种雅思阅读“靶子”句式——“浅尝辄止，管中窥豹”，我们已经说完了，雅思考生们都明白了吗?下面，我们来看最后一种雅思阅读“靶子”句式，雅思考生们跟着青岛朗阁小编继续向下看吧~

　　3.底气不足，猜测多于肯定

　　例1：Cam 10 T3 R2 autumnleaves

　　“Some theories aboutanthocyanins have argued that they might act as a chemical defence againstattacks by insects or fungi, or that they might attract fruit-eating birds orincrease a leaf's tolerance to freezing. However there are problems with eachof these theories, including the fact that leaves are red for such a relativelyshort period that the expense of energy needed to manufacture the anthocyaninswould outweigh any anti-fungal or anti-herbivore activity achieved.”

　　这个雅思阅读段落的开头提出anthocyanins可能(might)的三个功能：defenseagainst attacks by insects or fungi, attract birds以及increaseleaf’s tolerance to freezing.第三行的However there are problemswith each of these theories把三个可能的功能都反驳掉。

　　引申：

　　剑10的这篇讲秋天树叶变红原因的文章是雅思阅读里不太常见的“现象解释类”文章，在D/E/F三个段落里分别分析了树叶变红的原因，纵观雅思阅读，“现象解释类”文章的套路是把最合理的假说或者假设放在最后提出，考生们对此要有个基本的认识。以本篇为例：

　　D: Anthocyanins:

　　Function 1: defenseagainst attacks by insects or fungi

　　Function 2: attractbirds

　　Function 3: increaseleaf’s tolerance to freezing

　　Conclusion: Howeverthere are problems with each of these theories.

　　E:(承接D段提出新理论)Ithas also been proposed that…

　　Conclusion: the flaw(n缺点;缺陷) inthis theory lies in…

　　F:perhaps the most plausible(adj 有说服力的)suggestionas to…

　　小结：

　　考生们需要在日常雅思阅读备考中不断提高自己“见一叶而知秋”的能力，也就是要提高自己在阅读中对行文内容走向的预判能力，只有这样才能提高自己的雅思阅读解题效率。同时，只有奠定了这样的基础，才可以更好地应对出国后比较繁重的阅读任务，雅思考生们加油吧~
