【答案】第1题:B

第2题:F

第3题:E

第4题:A

第5题:C

【解析】（1）空前指出许多动物灭绝了，而接下来第二段指出，我们可以根据石头推测已灭绝的动物形状。前后为对立的两种情况,而B项开头的nevertheless正好表示转折，意思是：尽管如此，我们对它们了解很多，因为它们的骨头和贝壳是作为化石保存在岩石中的。从它们我们可以看出它们的大小和形状，它们走路的方式，它们吃的食物种类。该选项起到了衔接第一段和第二段的作用。

（2）此空时衔接第二段和第三段,选项F的最后一句与空白后的第一句密切相关。空白后第一句讲：我们所知道的几乎所有化石都是被保存在了由于水的作用而形成的岩石中，而且大多都是生活在水里或水边的动物。选项F提到：becarriedawaybystreamsintolakesorthesea,getcoveredbymud等，都是在讲水的作用形成化石；而最后一句“直到其骨头或外壳嵌进石头并被保存下来”，空格后也有一个preserved与之对应。因此F为此处正确答案。F意为：动物死后，其身体、骨骼或外壳通常会被溪流带走，流入湖泊或海洋，并被泥土覆盖。如果这只动物生活在海里，它的身体可能会下沉并被泥土覆盖。越来越多的泥土会落在上面，直到骨头或贝壳被嵌入并保存下来。

（3）53空后一句:还有像螃蟹一样的生物，其身体表面是一层角状物。紧接着后面部分介绍了这类动物的外貌特征。空后一句有一个“also”，由此推测空格处应该是关于另一种海洋生物。选项E提到starlilies这种海洋生物。E意为：最早被发现的动物都是非常简单的动物，生活在海里。后来的形态更为复杂，其中包括海百合、星鱼的关系，星鱼有长长的手臂，被一根长茎附在海床或岩石上。

（4）空格处后一句为:Ofthese,theammonitesare…shell…animal,说明ammonites是前面所提某种动物中的一个例子，它们的特点是“有壳"。据此推测此处应为A项。A意为：有壳的水生动物在化石中的历史很久了，而且已知的有很多不同的种类。

（5）55空上段主要讲的是有壳水生动物。下段第一句讲：大约7500万年前，爬行动物时代结束了。由此可知，要填入的文字应该既承接上段提到的有壳水生动物，又能够引出下文的爬行动物这样的内容。只有选项C中有相关的词gaverisetothereptiles。C意为：第一批真正有脊椎的动物是鱼类，最早出现在3.75亿年前的岩石中。大约3亿年前，两栖动物出现了，它们能够在陆地和水中生活。它们是巨大的，有时长达8英尺，其中许多生活在我们的煤层或岩层形成的沼泽水池中。两栖动物产生了爬行动物，在近1.5亿年的时间里，这些爬行动物是陆地、海洋和空中的主要生命形式。

15.单选题

Each（）effortababymakesatspeechisasignofintellectualdevelopment.

问题1选项

A.cordial

B.compact

C.clumsy

【答案】C

【解析】考查形容词辨析。A选项cordial“热情的，真诚的”；B选项compact“体积小的，精制的”；C选项clumsy“笨拙的，不灵活的”；D选项chronic“长期的，慢性的”。句意：婴儿在说话时的每一次（）努力都是智力发展的标志。“每一次热情的/体积小的/长期的努力”都没有“笨拙的”更合适，因此C选项正确。

【答案】第1题:B

第4题:A

第5题:A

【解析】文章第一段提到动作的氧化代谢率对它们生存方式造成的影响（inanyanimalhasaprofoundeffectonitslivingpatterns）；第二段解释无氧糖酵解（Anaerobicglycolysisisaprocessinwhichenergyisproduced,withoutoxygen,throughthebreakdownofmuscleglycogenintolacticacidandadenosinetriphosphate(ATP),theenergyprovider）；第三段提到了无氧糖酵解的不足以及对动物的生存产生的影响。综上所述，选项B符合题意。

文章第三段第一句提到了补偿的局限性（therearelimitations,however,tothiscompensation），指出动物由于无氧糖酵解所导致的大量能量消耗必须得到补偿，然后又通过小松鼠为例来说明小型动物补偿的时间短，而大型动物则需要很长的时间才能完成补偿，这就是补偿的局限性。选项B符合题意。

文章第二段第二句话Theamountofenergythatcanbeproducedanaerobicallyisafunctionoftheamountofglycogenpresent——inallvertebratesabout0.5percentoftheirmuscles’netweight.Thustheanaerobicenergyreservesofavertebrateareproportionaltothesizeoftheanimal提到了无氧糖酵解与动物体型的关系。随后举了恐龙的例子来解释说明肌肉越多，糖原质的含量就越多，体型大，肌肉多，选项D符合题意。

文章主要介绍无氧糖酵解对动物的生存产生的影响，没有使用一些非常晦涩难懂的专业知识，因此作者最可能针对的是刚刚接触相关学科的人群。选项A符合题意。
