Section Ⅰ Use of English Directions: Read the following text. Choose the best word(s) for each numbered blank and mark A,B,C or D on ANSWER SHEET 1(10 points) The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, 1 this is largely because, 2 animals ,we stand upright. This means that our noses are 3 to perceiving those smells which float through the air, 4 the majority of smells which stick to surfaces. In fact 5 , we are extremely sensitive to smells, 6 we do not generally realize it. Our noses are capable of 7 human smells even when these are 8 to far below one part in one million. Strangely, some people find that they can smell one type of flower but not another, 9 others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate 10 smell receptors in the nose. These receptors are the cells which sense smells and send 11 to the brain. However, it has been found that even people insensitive to a certain smell 12 can suddenly become sensitive to it when 13 to it often enough. The explanation for insensitivity to smell seems to be that brain finds it 14 to keep all smell receptors working all the time but can 15 new receptors if necessary. This may 16 explain why we are not usually sensitive to our own smells we simply do not need to be. We are not 17 of the usual smell of our own house but we 18 new smells when we visit someone else's. The brain finds it best to keep smell receptors 19 for unfamiliar and emergency signals 20 the smell of smoke, which might indicate the danger of fire. 1. [A]although [B]as [C]but [D]while 2. [A]above [B]unlike [C]excluding [D]besides 3. [A]limited [B]committed [C]dedicated [D]confined 4. [A]catching [B]ignoring [C]missing [D]tracking 5. [A]anyway [B]though [C]instead [D]therefore 6. [A]even if [B]if only [C]only if [D]as if 7. [A]distinguishing[B]discovering [C]determining[D]detecting 8. [A]diluted [B]dissolved [C]determining[D]diffused 9. [A]when [B]since [C]for [D]whereas 10. [A]unusual [B]particular [C]unique [D]typical 11. [A]signs [B]stimuli [C]messages [D]impulses 12. [A]at first [B]at all [C]at large [D]at times 13. [A]subjected [B]left [C]drawn [D]exposed 14.

[A]tolerate [B]repel [C]neglect [D]notice 19. [A]availabe [B]reliable[C]identifiable[D]suitable 20. [A]similar to[B]such as [C]along with [D]aside from 1. [答案] [C] [分析] 这是一道语义辨析题,首先排除选项 [A]although,因为 although 用作连词一般引导让步状语从句。 [B]的 as 在句子中表示因果关系,那么与其后的 because 又重叠,也可排除;选项 [D]的 while 一般表示对比关系,此题的正确答案只能是选项 [C]表示转折连词的 but。 2.[答案] [B] [分析]第是一道语义辨析题,应该选B选项。句子前半部分的 “compared with”是一个关键词组,暗示“人类”和“动物”之间实际上是对比关系。首先排除选项[A]above (在上面,在高处)。又[C]excluding 不表示句子成分之间的对比关系,而主要阐明成分之间的包含与被包含的关系。而选项[B]unlike (不同的,不相似的) 可指外表、性质上的不同,表示一种对比关系,因此选[B] 3. [答案] [A] [分析]这是动词搭配辨析题,第三句话对第二句话的意思进行说明,指出“人的鼻子局限于某些嗅觉--飘浮于空中的嗅觉”,那么第三空选[A]“limited”比较合适。干扰性大的有的选项是[D]confined, 两者均有"局限,限制"的意思,但含义上略有不同。Limit一般只在实践、空间、数量、质量或产量等方面有一个范围或限度,属于中型。而confine择优束缚、羁绊、限制自由或禁闭的隐含意思,它带有一种强制性,因此confine放在句子中与其明显不符,过于强硬和绝对。所以选[A]。 4. [答案] [C] [分析] 这是一道语义篇章和词义辨析题。可能出在两个之间,就是人不是不去感知,而是因为直立把许多味道错过了,我们应该选择C;由前一句话可知,“人的鼻子主要捕捉空中漂浮的嗅觉,而对于黏附于物体表面的嗅觉就可能忽略”,这样[C]选项“missing”为正确答案。 5. [答案] [B] [分析] 此题考查的是对上下文语义的理解及连词的使用。尽管我们没有感知到很多地面的气味,如果我们感知的话还是可以感知到的,所以应该选择B;这里对文章开始的大众观点进行了转折,注意提示词“Infact”,正确答案“B”“though”,表达了这种转折关系,为正确答案。如果选[C]或[D],那么就与“In fact”无法搭配。 6. [答案] [A] [分析] 此题考查的是对句子逻辑关系的理解和掌握。 本题选的是A,假设关系是完型填空当中常考的一种关系——让步关系,意思是 “即使我们一般不会意识到某些嗅觉,但我们仍然对这些东西感觉灵敏”。符合这一要求的只有[A]“evenif”。 7. [答案] [D] [分析] 这是一道动词语义辨析题。 本题选的是D,一个假设性的,鼻子用来干吗的?是用来感知的,我们选择D;要求 选一个跟嗅觉能搭配的动词,那么,[D]选项“detecting”是对的。 8. [答案] [A] [分析] 这仍是一道动词语义辨析题。本题,就它的意思是“即使这些嗅觉的浓度冲淡到原来的百万分之一,人们仍然能够捕捉到这些嗅觉”,是A;词汇的辨认。如果能够知道 [A]选项“diluted”表示“冲淡”的意思,就能选到这个正确答案。 9. [答案] [D] [分析] 此题考查的是对句子逻辑关系的理解和连词的使用。 本题选择的是D,要填的东西必须表达这种对比。很明显,“D”选项“where as”是正确答案。表示对比关系。 10. [答案] [B] [分析] 这是一道语义辨析题,主要考查形容词的辨析。 本题选B,是“B”选项“particular”是正确答案,其他选项放到原文 都不符合逻辑,我们鼻子对某些类别的味道很敏感。 11. [答案] [C] [分析] 此题考查的是对上下文语义的理解和动词的搭配。 本题是一致性的题,这考察和上次说的我们鼻子的感知信号是一致的,注意句子中间 表示并列关系的连词“and”。前半句说“这些接收器能够感觉到嗅觉”,因此“C”选 项“messages”是正确答案。 12. [答案] [A | |||||
