25、 J. as K. happy L. plenty M. sorry N. same O. prove（分数：25.00）解析：H解析 根据空后 where引导的定语从句可知，A sort of 后面接一种想象中的地方，imagine 的一般是一种好的，梦想中的东西，为名词，选项中只有 paradise是名词。解析：I解析 作者这里用 the other side起头重新讲述了另外一个环境，是对比作用，意为“正好相反”，用 opposite。解析：E解析 此词后面接的是 death，to death 前面一般是死的方式，为动词，在选项中只有 starve最接近最合理。解析：C解析 此处应该填形

26、容词，修饰 boat，根据后面的 repaired和前面的 badly这一副词，可以得知这艘船应该是坏的，故选 damaged，此处是过去分词作形容词。解析：G解析 根据 to可知，此处应填入动词原形，剩余选项中只有 prove和 sink。从后面的内容可以看出他们被困孤岛，而在海上出事被困大多数都是因为船坏而沉，选项中正好有这个选项。解析：O解析 根据 did not可知，此处应填入动词原形，剩余选项中只有 prove为动词原形。另外前面说到岛上没有水也没有树，后面用 but转折，可见是没有什么问题，选项中只有 prove可以和 to be搭配，prove to be意为“被证明，实际上”。

27、解析：F解析 纵观整句可知，此处缺少谓语动词，全篇文章用了过去时，所以此处应填入动词过去式，剩余选项中只剩下 sank和 collected，从文章的上下文也可知这些人只有收集水才能在这里生存下去。故选 collected。解析：J解析 此处句子不缺成分，所以可以看出是缺一个连词，两句应该是因果关系，因为有枪，所以有吃的，故可以用选项中的 as。解析：L解析 同上题，有枪则可以去打猎，故有很多吃的可以吃，在 few和 plenty中可以选 plenty，表示很多，而 few指很少。解析：M解析 第二段第一句话说两个男士在岛上待了五天，希望可以再待久一点。可知他们最后非常不想走，故选形容词，so

33、解析 根据后面，这些专家建议你不要碰任何的脂肪和蛋白质的观点是错的，可知专家的看法是反对脂肪和蛋白质的摄入。此句缺动词，而加在 are后面，又是 nowadays引出的，可知用动词现在时，warning against即“警告”搭配正确，意义也正确。解析：E解析 这些专家的观点可以从上下文看出来，他们建议远离脂肪和蛋白质，此处 in doing something，故用 advising。解析：D解析 这句话的后面介绍了脂肪和蛋白质的作用，此处领起后文，此处应填 functions, serve.function为固定搭配。解析：K解析 Provide 后接名词，选项中名词只有 energy符

34、合题意，脂肪提供能量也合理。解析：M解析 这句话中 they指能量，而且应该为被动式，即过去分词，只有 stored是过去分词，能量在身体中储备以备将来之用，这个意思也完整准确。解析：G解析 根据 for和空后 the body against disease可知，此处应填入名词，剩余选项中只有defending和 collecting。根据文意可以推断出，蛋白质可以保护我们对抗疾病，defend against 是固定搭配。故选 defending。解析：O解析 纵观整句可知，此空及其后的 in fact作 something的后置定语，故此空应填入形容词。再根据此句中 and前的 high

35、 in protein“富含蛋白质”可推断出此空应意为“富含脂肪”，故选 rich。解析：B解析 根据空前 the可知，此处应填入名词，剩余选项中只有 road为名词，故选 road, on the road to表示“在的路上”。The great ship, Titanic, sailed for New York from Southampton on April 10th, 1912.

41、她有 16间水密舱”，所以此船被认为是“不沉的”。只有 unsinkable符合文意，意为“大家都认为这艘船是永不沉没的”。解析：E解析 此句话缺一个动词，又由 be一词可以推断这个词为过去分词，故选 remembered或者plunged，而符合题意的只有 remembered。解析：M解析 此句话讲的是这是这艘船的首次，根据 went down可以推测是首航，故选 voyage。解析：C解析 根据上下文可以推测，这里讲的是当船开出四天后，set out 是固定搭配，after 后面接doing something。故选 setting out。解析：F解析 可判断此处填名词，名词有 pas

42、sengers，voyage，collision，horror，presentation，只有 collision符合题意，意为“突然转向以防直接碰撞”。解析：O解析 此处应该填形容词，形容一种微小的声音，只有 trembling可以形容，意为“颤抖的微弱声音”。解析：I解析 此处填名词，意为“船长的”，根据后面可知船长发现船在快速下沉，在名词选项可以看出 horror是最为贴切的。解析：G解析 后文可得知人们都跳进了水中，可见大家是弃船逃生了，故选 abandon ship。解析：D解析 一般在船沉没的时候，人们只能跳水逃生，在所有动词中，只有 plunged可以与 into搭配表示跳入水中

48、患自闭症的概率，文中的研究得出的数据 19%应该是平均值，故选 average。解析：H解析 此空在形容词 higher前面，修饰 higher，故为副词，又根据前后的百分比对比，得知差距明显，这里应该是一个表示程度大的副词，形容词中 dramatically“大幅度地”符合题意。解析：L解析 此句缺少主语，由于空格后是动词原形，故这里需要复数名词。作者这里说的是一种研究结论，所有名词里面只有 results符合题意。解析：M解析 空格前为名词 factors，空格后为介词 by，故此处缺少一个过去分词。根据文意推测作者在这里想表达的是兄弟姐妹在母体时的环境是相同的，故选 shared。解析：

49、B解析 由前面的冠词 the可知这里需要填一个名词，以上段落讲述的是研究内容和结果，那么这里研究人员所推荐的内容自然是基于上述发现结果，故选 basis。解析：J解析 此从句需要一个动词，从 closely，pick up 和 signs可以推断研究者建议医生要观察、监控孩子，故用 monitor。解析：I解析 这里需要一个动词连接前后的句子，观察上下文可以看出后面的内容是对前面的 signs of the disorder的解释，故选项中的 including符合题意。解析：E解析 根据前面的形容词 early可以看出这里需要填一个名词。而从前面的内容可看出，作者一直在强调对儿童的观察、确诊，可见早期发现对于治疗是有好处的，故选名词中的 detection“发现”符合题意。解析：O解析 根据前面的 its可以看出这里要填名词，又由前面的 treat“治疗”可以看出这个名词一定和疾病有关，故选 symptoms“症状”。
