Question

【题目】Can trees talk? Yes-but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree(柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. The even more astonishing, the tree sent out a special vapor-a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.

Communication, of course, doesn’t need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar(花蜜) for honey. So why shouldn’t trees have ways of sending messages?

【1】When attacked, a window tree will protect itself by ________.

A. changing its leaves’ chemistry B. changing its leaves’ colour

C. talking to caterpillars D. sending out a special vapour

【2】From the passage we know that caterpillars_________.

A. like willow trees B. enjoy eating fallen leaves

C. feed on willow tree leaves D. could communicate with willow trees

【3】Caterpillars will stop eating willow trees leaves which__________.

C. are being attacked D. are communicating

【4】According to the passage, how do willow trees communicate with each other ?

【3】 A

【4】 B

【解析】

本篇科普文章讲述了柳树通过发出一种特别水蒸汽来同邻居进行交流。作者认为像人类微笑，鸟儿唱歌，蜜蜂跳舞一样，树也有传送信息的方式。

【1】细节理解题。由句子First a willow tree(柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. 首先，一棵柳树在树林中遭到了毛虫的袭击，改变了柳树的叶子的化学性质，使它们的味道非常可怕，以至于毛虫厌倦了树叶，不再吃叶子了。可知，当柳树受到攻击时，它会通过改变树叶的化学成分来保护自己。故选A。

【2】推理判断题。由句子First a willow tree(柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. 首先，一棵柳树在树林中遭到了毛虫的袭击，改变了柳树的叶子的化学性质，使它们的味道非常可怕，以至于毛虫厌倦了树叶，不再吃叶子了。可知，毛毛虫以柳叶为食。故选C。

【3】细节理解题。由句子First a willow tree(柳树) attacked in the woods by caterpillars (毛毛虫) changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. 首先，一棵柳树在树林中遭到了毛虫的袭击，改变了柳树的叶子的化学性质，使它们的味道非常可怕，以至于毛虫厌倦了树叶，不再吃叶子了。可知，当柳树叶子有化学变化，变得无味时，毛毛虫会停止吃柳树叶子。故选A。

【4】细节理解题。由句子The even more astonishing, the tree sent out a special vapor-a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty. 更令人惊讶的是，这棵树散发出一种特殊的蒸汽——一种信号，使得它的邻居们改变他们自己的叶子的化学性质，使它们不那么美味。可知，他们通过散发出一种特殊的蒸汽来交流。故选B。

用细节定位法来做细节理解题。

细节理解题属直接解答性问题，是阅读理解题中最简单的一种，多数属中低难度的送分题。但由于中考所占的比例很大，应特别引起注意。

事实和细节题的命题特点是：把某词语、某个句子或某具体事实用不同于原文的另一方式或句型表达，即同义改写。解答这类题的窍门是：A)注意掌握英语的多种表达法；B）正确分析词语在句中的作用；C）熟练运用英语的句型转换；D）读懂题干所提出的问题，并准确地找到文中涉及该问题的句子。

做细节题具体方法与步骤如下：

略读材料,大概了解原文，掌握中心或主旨。

按文章的体裁，作者写作的组织模式及有关的信息词，如for example，first，second…等预测应该到何处寻找自己所需要的事实。

③ 将自己精力放在寻找你所需要的细节上，快速通篇跳读，眼睛自左至右，自上而下呈Z形扫视，直到找到细节出处，待找到含细节句子时，放慢速度，仔细核对比较内容，直至找到答案。
