文只提到软木橡树的树皮能长到20厘米的厚度，并未提到它的树皮是否是所有树中最厚的。Question2答案：FALSE关键词：asyntheticcork;samecellularstructure定位原文：第二段第三句“…thebarkofthecorkoakhasaparticularcellularstructure…thattechnologyhasneversucceededinreplicating”解题思路：原文提到这种树有着特别的细胞结构，而且如今的技术还未能成功复制这种结构。Question13答案：desertification关键词：corkforests定位原文：最后一段倒数第二句：“Moreover,corkforestsarearesourcewhichsupportlocalbiodiversity,andpreventdesertificationintheregionswheretheyareplanted.”解题思路：题目中的stop对应文中的prevent，文中提到软木橡森林能够预防种植区域出现沙漠化。雅思阅读备考资料怎么选雅思阅读备考中，考生可以参考一些专业的资料，指导我们更有效的进行备考。面对市面上这么多资料，很多考生表示不知道怎么选择。接下来小编为大家推荐一些雅思阅读备考资料，希望能帮助各位考生有效备考雅思阅读。一、雅思阅读资料的选择考生在选择雅思备考资料时，可以根据三个标准来选择，即阅读基础类，技巧类以及练习类。考生哪一方面不足就要适当选择哪一方面的备考资料。除了这些与雅思阅读考试非常相关的备考资料之外，考生还可以适当接触一些比较原汁原味的英语文章，比如BBC，国家地理杂志，新科学家杂志等等。当然，考生也要根据自身的实际水平去选择。如BBC，国家地理杂志的文章内容丰富，形式和结构比较活泼并充满视觉冲击力，更适合刚接触G类雅思阅读考试且英语基础较薄弱的考生。二、雅思阅读技巧如何提高?雅思阅读技能培养主要强调的是阅读理解技能的培养。考生不仅要注重阅读，更要注重理解，也就是说在阅读的基础上加之对文章内容的理解，这样才能快而准的解题。想要达到此目的，考生就要制定雅思阅读理解能力提升计划，从背景知识，词汇，语法，泛读，精读四方面着手准备。背景知识对理解文明起到举足轻重的作用，比如如果对英国政党制度没有一定了解的话，经济学人上的关于英国工党选举的那些事就很有可能看不懂，尽管知道每个单词每个短语的意思。词汇是阅读理解的基石，语法对阅读理解的准确率有很大的影响，比如长难句理解不透彻的话，理解起来就会吃力，泛读和精读是提升阅读速度和质量
