D。away答案：1。B从上文“Alllivingorganismsmustfeedsothattheycanhaveenergy.”可知此处意为植物作为一种生物也不例外.2。D从下文“Theydonothaveamouthoradigestivesystem…”可知此处意为它们与动物的取食方式不同。而选项accurate强调的是“精确性"，也就是说,accurate暗含有它们两者之前的取食方式有可能比较类似，根据文章，它们的取食方式是截然不同的，所以D项更准确些.A。本段主要内容讲植物的取食方式，那么可知这里是指“捕食"，而不是获取营养、水或者敌人。B.从本段可知，植物含有水分，从下一段的第一、二两句描述可知除了水分之外,植物还由矿物质和有机物构成，所以总共是threethings。B.从下文的“Often，morethan90%ofaplantismadeofwater.”可知水是最重要的.C。从本句前部分强调水是一种液体，那么，逻辑推理,这里主要强调植物是“固体”的。后一部分的解释说明“…especiallywhentheyaremadeofwood，liketrees.”可进一步佐证.A.从本句的关键词dryaplantout以及下面的细节inthesolidpartsofplants可知是先把水全部去除。D。从下文的实验细节尤其是最后两句可知是通过火烧的方法把两种物质分离开.29.B。根据下文内容可知，火烧到最后，就只剩下灰烬了，有机物被烧掉了，灰烬主要是由矿物质构成的。30。D。根据上文可知,灰烬主要是由矿物质构成的,那么被烧掉的部分就是有机物.burnaway“烧掉”。2语法填空阅读下面短文，按照句子结构的语法性和上下文连贯的要求,在空格处填入一个适当的词或使用括号中词语的正确形式填空，并将答案填写在答题卡标号为31-40的相应位置上。词数：139完成时间：8分钟难度：＊*Manypeoplebelievethatthey31(suppose)todrinkeightglassesofwater
