19、此结构可以由“Had+主语+-ed分词”代替，通常否定词不随助动词前置。2.It is a common theme in many science fiction stories that the world may one day be _ by outer space invaders.（分数：2.50）A.broken inB.taken overC.run overD.filled in解析：考点 考查固定搭配。3.The three men tried many times to sneak across the border into the neighbouring count

20、ry, _ by the police each time.（分数：1.00）A.had been capturedB.being always capturedC.only to be capturedD.unfortunately captured解析：考点 语法成分。句意：这三个人多次试图偷偷越过边境溜入邻国，却每次都被警察逮住。only to do sth. “结果却，不料”，表示出乎意料或不如人意的结果。4.The actress wanted a hat to _ her dress.（分数：2.50）A.go byB.go throughC.go outD.go with解析：考

21、点 考查动词词组辨析。5.Looking at what he has done for those disabled children, one _ forgive his sin.（分数：2.00）A.cannotB.cannot helpC.cannot butD.cannot to解析：解析 本题考查固定搭配。cannot but意为“不能不，不由得不”，后接不带to的不定式，即cannot but do sth.，类似用法的还有might as well, cannot choose but, do no more than等。A用在此处意为“不能原谅”，不符合语境；B为cannot

22、 help do sth.结构，表示“不能帮助做某事”；D表达错误。故选C。6.The policemen went into action _ they heard the alarm.（分数：2.50）A.promptlyB.presentlyC.quicklyD.directly解析：考点 考查词义辨析。7.During our stay in London, we paid a visit to the hospital founded _ the nurse Florence Nightingale.（分数：2.50）A.in line withB.in honor ofC.in f

31、indicate the danger of fire.（分数：25.00）解析：H 考点 考查形容词。 该句意为“和动物相比，人们通常认为人类的嗅觉没有动物那么 -|_|-，这大可归结于我们人类是竖直站立的。”分析句子结构可知，空格处应填形容词。根据文章第一句“人类的鼻子是被低估了的工具”和常识可知，因为人是直立行走的，造成了人类的嗅觉不如动物灵敏的假象，故空格处应填H项，insensitive意为“感觉迟钝的”。解析：O 考点 考查介词。 前文出现了compared with animals，因此这里表示的也是人类与动物的对比关系，并不涉及任何包含关系，故可排除B项excluding，最适

32、合的答案是O项unlike“不像，与不同”，用来表示“人类和动物不同，我们是竖直站立的”。解析：L 考点 考查动词。 空格处需填一个现在分词，在that引导的宾语从句中，该分词作结果状语。因为前半句已经说明“人类的鼻子只限于感知飘浮在空气中的气味”，此处应该继续说“因此人类闻不到大部分附着在地面的气味”。miss意为“错过，漏掉”；exclude意为“排除，排斥”。人类因直立行走而闻不到这些气味，即“错过”这些气味，因此L项missing符合句意。解析：F 考点 考查动词。 该句意为“我们的鼻子能够察觉到人类的气味，即使这些气味被 -|_|-到远低于百万分之一”。综观选项，dilute意为“稀

33、释，使变淡”，dissolve意为“溶解”，可以推断气味只能是被“稀释”到远低于百万分之一，故选F项diluted。解析：C 考点 考查副词。 空格位于句首且后面有逗号，可判断空格处所填词作状语且首字母大写。根据上下文，该句意为“ -|_|-，对于两种花香，有些人只能闻到其中一种，而其他一些人对两种花香都很敏感”，空格处应表示大家对这种现象感到很奇怪，故选C项Strangely“奇怪的是”；K项However表示转折，句中并没有转折的意思，故排除。解析：J 考点 考查名词。 空格处需填一个名词作send的宾语。该句意为“这些感受器是能够闻到气味并向大脑传递 -|_|-的细胞。”综观选项，sig

34、n意为“符号；标记”，message意为“消息”；这里要传递的是信息而不是符号，M项signs是干扰项，只有J项messages符合句意。解析：A 考点 考查动词。 该句意为“然而，有研究发现：即使原本对某种气味不敏感的人，当经常 -|_|-该气味时，也能突然对它变得敏感起来”，表示人与气味之间的关系最有可能用到的动词就是“闻到”，综观选项，只有A项exposed“暴露；使接触到”意思与之接近，be exposed to意为“使某人接触某种环境”，在此即为“让那个人经常闻那种气味”，故选A。解析：D 考点 考查形容词。 此处意为“大脑发现让所有的嗅觉感受器都同时工作时会 -|_|-”。选项中D

35、项inefficient意为“无效率的，效率低的”，I项insufficient意为“不充足的”。根据常识可以推断出，多种感受器同时工作可能会导致“效率低下”，而非“不充分”，故D项inefficient,符合句意。解析：G 考点 考查动词。 空格所在句意为“我们意识不到自己家里的味道，但当我们去别人家里拜访时，就会 -|_|-新气味。”由句意和生活常识可知，作者此处要表达的是我们能够注意到别人家里的味道。G项notice意为“注意到，留意到”，符合句意，因此选G。解析：E 考点 考查名词。 根据such as the smell of smoke，which might indicate t

36、he danger of fire(例如，闻到烟味就可能意味着有火灾的危险)可知，此句是对emergency -|_|-的同义转述，根据常识可推测，空格所在短语的意思为“紧急信号”，E项signals意为“信号”，M项signs强调“标志；符号”，故选E。三、PART WRITING(总题数：2，分数：34.50)11.Which is a better choice, to buy a house on mortgage or to rent a house?
