练习一
A language is a signaling system which operates with symbolic vocal sounds (语声), and which is used by a group of people for the purpose of communication. Let’s look at this 61 in more detail because it is language, more than anything else, 62 distinguishes man from the rest of the 63 world.
Other animals, it is true, communicate with one another by 64 of cries: for example, many birds utter 65 calls at the approach of danger; monkeys utter 66 cries, such as expressions of anger, fear and pleasure. 67 these various means of communication differ in important ways 68 human language. For instance, animals’ cries do not 69 thoughts and feelings clearly. This means, basically, that they lack structure. They lack the kind of structure that 70 us to divide a human utterance into 71.
We can change an utterance by 72 one word in it with 73: a good illustration of this is a soldier who can say, e.g., “tanks approaching from the north”, 74 who can change one word and say “aircraft approaching from the north” or “tanks approaching from the west”; but a bird has a single alarm cry, 75 means “danger!”
This is why the number of 76 that an animal can make is very limited: the great tit (山雀) is a case 77 point; it has about twenty different calls, 78 in human language the number of possible utterances is 79. It also explains why animal cries are very 80 in meaning.
61.A.classification B. definition C.function D.perception
62.A.that B. it C.as D.what
63.A.native B. humanC. physical D. animal
64.A.ways B. means C. methods D. approaches
65.A.mating B. exciting C. warning D. boring
66.A.identical B. similar C. different D. unfamiliar
67.A.But B.Therefore C. Afterwards D. Furthermore
68.A.about B. with C. from D. in
69.A.infer B. explainC. interpretD. express
70.A. encourages B. enablesC. enforcesD. ensures
71.A.speeches B. soundsC. wordsD.voices
72.A. replacingB. spellingC. pronouncingD.saying
73.A.ours B. theirsC. anotherD. others
74.A.so B. andC. butD.or
75.A.this B.thatC.whichD.it
76.A.signs B.gesturesC.signalsD.marks
77.A.in B.atC. ofD.for
78.A.whereas B. sinceC. anyhowD.somehow
79.A.boundless B. changeableC. limitlessD. ceaseless
80.A.ordinary B. alikeC. commonD. general
【答案】：
61.B 62.C 63.C 64.B 65.C
66.C 67.A 68.C 69.D 70.B
71.C 72.A 73.C 74.B 75.C
76.C 77.A 78.A 79.C 80.B
【答案解析】：
61.B 此题考查普通词汇。上文给出的明显是语言的定义，因此，答案选definition。
62.C 此题考查的语法点是定语从句。从空缺前的逗号可以推断出，这是个非限定性定语从句，四个选项中，能作为非限定性定语从句的关系代词的只有as，表达“正如语言将人类和其他物质区分开来的一样。”
63.C 此题考查上下文理解。语言将人和物质世界的其他物质区分开来。
64.B 此处考查固定搭配，by means of表示“通过……方式或途径”。因此，选B。
65.C 此处考查词汇和上下文理解，在危险来临之际，鸟儿们发出的应该是警告声。故选warning。
66.C 从后文可得知，猴子能通过声音表达愤怒、恐惧和高兴。由此推断可知，猴子发出的叫声应该是不同的。故选C。
67.A 此处考查介词及上下文理解，作者旨在拿动物发出的声音和人类的语言进行比较。前文叙述动物也能发出不同的声音，这里说的是动物的交流方式与人类语言在几个重大的方面是不同，前后文为转折关系。故选but。
68.C 此处考查固定搭配：differ from(与……不同)。
69.D infer表示“推断”，explain指“解释”，interpret表示“解释、说明”。这里选express(表达)最符合文意。 70.B 见71题。
71.C 这两题放在一起来分析。原文意思应是：“人类拥有能把话语细分成单词的某种结构，而动物却没有。”70题的encourage(勇敢)，enforce(强迫)，ensure(保证)都不符合题意。而71题，比话语更小的单位应该是words。故此题选C。
72.A 此题考查上下文理解。下文举例说明的部分提到将一句话的某个词换成另外的词，由此推断可知，此处选择replace(代替)。
73.C 表达用另一个词代替，用another。
74.B 此题考查上下文理解，会说一句话和能够把这句话里的某个单词用别的词替换，这之间表达的应是一种并列关系。故选B。
75.C 此题考查非限定性定语从句，必须用which。
76.C 动物发出的声音不能形容为“标记”、“记号”或是“手势”，因此，只有signal信号才是正确选择。
77.A 此处考查固定搭配。in point指“适用的，相关的”
78.A 作者将山雀能发出20种叫声与人类语言能发出更多的声音相比较，这里应该选择转折连词：whereas(然而)。
79.C 参照上题，此处将人能发出的声音数量与动物进行比较。boundless(无界限的)，changeable(多变的)，ceaseless(不停歇的)，因此，正确选项是C。
80.B 根据上文，动物只能发出有限的声音，那它们的叫声显然只能是相似的了。因此，B是正确答案。
练习二
It’s an annual back to school routine. One morning you wave goodbye, and that 71 evening you’re burning the late?night oil in sympathy. In the race to improve educational standards, 72 are throwing the books at kids. 73 elementary school students are complaining of homework 74. What’s a well?meaning parent to do?
As hard as 75 may be, sit back and chill, experts advise. Though you’ve got to get them to do it, 76 helping too much, or even examining 77 too carefully, you may keep them 78 doing it by themselves. “I wouldn’t advise a parent to check every 79 assignment,” says psychologist John Rosemond, author of Ending the Tough Homework. “There’s a 80 of appreciation for trial and error. Let your children 81 the grade they deserve.”
Many experts believe parents should gently look over the work of younger children and ask them to rethink their 82. But “you don’t want them to feel it has to be 83,” she says.
That’s not to say parents should 84 homework—first, they should monitor how much homework their kids 85. Thirty minutes a day in the early elementary years and an hour in 86 four, five, and six is standard, says Rosemond. For junior?high students it should be “ 87 more than an hour and a half,” and two for high?school students. If your child 88 has more homework than this, you may want to check 89 other parents and then talk to the teacher about 90 assignment.
71.A.very B. exact C. right D. usual
72.A.officials B. parents C. experts D. schools
73.A.Also B. Even C. Then D. However
74.A.fatigue B. confusion C. duty D. puzzle
75.A.there B. we C. they D. it
76.A.via B. under C. by D. for
77.A.questions B. answers C. standards D. rules
78.A.off B. without C. beyond D. from
79.A.single B. piece C. page D. other
80.A.drop B. short C. cut D. lack
81.A.acquire B. earn C. gather D. reach
82.A.exercises B. defects C. mistakes D. tests
83.A.perfect B. better C. unusual D. complete
84.A.forget B. refuse C. miss D. ignore
85.A.have B. prepare C. make D. perform
86.A.classes B. groups C. grades D. terms
87.A.about B. no C. much D. few
88.A.previously B. rarely C. merely D. consistently
89.A.with B. in C. out D. up
90.A.finishing B. lowering C. reducing D. declining
【答案】：
71.A 72.D 73.B 74.A 75.D
76.C 77.B 78.D 79.A 80.D
81.B 82.C 83.A 84.D 85.A
86.C 87.B 88.D 89.A 90.C
【答案解析】：
71.A 早上刚说完再见，当天晚上就可怜兮兮的秉烛夜读。表示“完全的、正是”的概念，用very。
72.D 此题答案在下文中，小学生们抱怨作业太多，那此题当然选school学校布置的作业太多了。
73.B 这一句和上文应该是递进关系，学校的作业多，甚至连小学生也开始抱怨了。因此，此题选even。
74.A A答案fatigue意思是疲劳。根据上文，因为作业量太大，学生抱怨这么做带来的疲劳。
75.D 这个固定搭配里的it是形式主语，代替后文的sit back and chill。原文表示：“虽然很难做到，但是专家还是建议家长不要采取行动，冷静点”。故选D。
76.C 这里的you指家长，them指孩子。表达“以何种方式来让孩子做作业”，用介词by。
77.B 家长帮助孩子做作业的一个方法就是检查孩子作业的答案是否正确。因此，此题选择B answers。
78.D 此题考查上下文理解和固定搭配：keep sb. from doing sth.表达的是“不让某人做某事”。家长如果在孩子功课的问题上帮的太多的话，就不能养成孩子独立完成作业的能力了。
79.A 能够用来形容assignment的词只有A和B选项，但piece后一般应加上“of”才能修饰名词。故single完全符合题意。
80.D 此处考查上下文理解。由于父母给予孩子的帮助太多，因而缺乏对于尝试和犯错的一种欣赏。根据此意，答案应选D.lack。
81.B 从上文可得知，孩子们应该去挣他们应得的成绩。和挣学分一样，成绩也是挣来的。因此，选择earn。而acquire指通过努力获得知识和能力。
82.C 家长检查孩子的作业时让孩子们重新考虑的是什么呢?从四个选项来看，重新考虑错误之处mistake才是比较符合逻辑的。
83.A 这里考察上下文理解，虽然家长要孩子们重新考虑他们作业中的错误之处，但这并不代表要使孩子们达到完美的标准。符合逻辑的只有perfect。
84.D 此处考查词汇和上下文理解。虽然家长对孩子们的作业不能过分苛求，但也不能忽视作业。forget(忘记)，refuse(拒绝)，miss(错过)都不符合逻辑。 85.A 这里考查前后搭配have homework，故选A。
86.C “小学的前几年每天应花三十分钟写作业，而四、五、六年级应以每天一小时为标准。”“班级”、“群体”、“学期”显然不符合逻辑。
87.B 说完小学生，这里作者提到中学生。no more than在这里表示“不超过”，指中学应以一个半小时的标准来布置作业。
88.D 后文提到要和其他家长甚至是老师来沟通孩子作业量的问题，那么这里肯定表示孩子的作业量超标了。previously(之前地)、rarely(极少地)、merely(仅仅地)都不符合文意，只有consistently(一直以来地、一贯地)才表明作业量超标问题的严重性。 89.A 表达“和其他家长一起检查作业”用with。
90.C 这里空缺意思是“减少”，B、C、D三项都有“减少”之意，但lowering指降低某数字、价格或程度，declining表示降低，后不接宾语。故选C。
练习三
In a telephone survey of more than 2，000 adults，21% said they believed the sun revolved (旋转)around the earth. An 71 7% did not know which revolved around 72. I have no doubt that 73 all of these people were 74 in school that the earth revolves around the sun; 75 may even have written it 76 at test. But they never 77 their incorrect mental models of planetary (行星的) 78 because their every day observations didn’t support 79 their teachers told them: People see the sun moving 80 the sky as morning turns to night，and the earth seems stationary (静止的) 81 that is happening. Students can learn the right answers 82 heart in class，and yet never combined them 83 their working models of the world. The objectively correct answer the professor accepts and the 84 personal understanding of the world can 85 side by side，each unaffected by the other. Outside of class，the student continues to use the 86 model because it has always worked well 87 that circumstance. Unless professors address 88 errors in students’ personal models of the world，students are not 89 to replace them with the 90 one.

72.A.what B. which C. that D. other
73.A.virtually B. remarkably C. ideally D. preferably
74.A.learned B. suggested C. taught D. advised
75.A.those B. these C. who D. they
76.A.on B. with C. under D. for
77.A.formed B. altered C. believed D. thought
78.A.operation B. position C. motionD. location

87.A.in B. with C. on D. for
88.A.general B. natural C. similar D. specific
89.A.obliged B. likely C. probable D. partial
90.A.perfect B. better C. reasonable D. correct
【答案】：
71.C 72.B 73.A 74.C 75.D 76.A 77.B 78.C 79.D 80.B 81.C 82.B 83.A 84.D 85.A 86.C 87.A 88.D 89.B 90.D
【答案解析】：
71.C四个答案都有“额外”的意思，但各有偏重。A重在表达“过量、超过正常的部分”;B是“在一类事物之外的额外部分”;D是“外加的”。因此只有C答案符合本题要求：“另外有7%的人不知道是谁绕着谁转。”
72.B如上题所述，句中已有which，要表达“不知谁绕着谁转”的意思，只能选B。
73.A本题考词汇。virtually：实际上地;remarkably：很明显地;ideally：理想
地;preferably：更适宜地。从句意来看，只能选A。
74.C本句意：“实际上，这些人在学校都学过地球绕着太阳转的。”本句谓语用的是被动语态，故答案为C。
75.D本题考代词。承接上句，此处应为直接代替上句中所提到的人们，所以用they。
76.A此题考查固定搭配write on(记下，写下)。
77.B 由句中incorrect mental models一处可获得提示，“不正确的模型应该得到更正”，因此，此题选B答案。form：形成;believe：相信;think：认为。
78.C此句句意为：“但他们不肯改变脑海里错误的行星运动模式。”据意义判断，只有motion符合句意。选项中position和location都是表示静止位置的词，而行星是在不断运动中的，因此不能选。
79.D此题为意义和语法结合题。语法上，本题缺少的是宾语从句的引导词，在从句中作宾语，并具有自己的意义。因此，只有D的what才符合题意。
80.B本题缺少一个介词，本句意为：“人们看到太阳越过天际，因此有了日夜更替。”能和天空搭配，并体现运动感的介词只有B答案：across。
81.C本题考连词。句意为：“当这一切发生的时候，地球仿佛是静止的。”因此应选C：while。
82.B本题考固定搭配。by heart意为“用心熟记”;in heart意为“兴高采烈”，其他并无固定搭配选项。故应选B答案。
83.A此题考的又是固定搭配：combine sth. with sth.(将某物与某物结合起来)。故此选A。
84.D此题考上下文理解。根据文章意思，教授所提供的正确答案应该是和学生对于世界的个人理解并存。故此处应选D。
85.A如上题所述，表示存在的选项即为A。occur：发生;survive：存活;maintain：维持。
86.C本题考查文章理解和词汇的用法。在课外，学生仍使用他们自己脑中的模型。A答案强调“私人的”;B答案指“个体的”;D答案前应为形容词性的人称代词;惟有C可以表达主观的“个人想法”之意。故此，选C。
87.A此题考查介词的固定搭配。能和环境circumstance一词搭配的只有A：in。
88.D此题考查大家的理解能力。意为：“除非教师指出学生世界观模式中的某个错误，学生是不可能摒弃自己的观点，而认可正确观点的。”由此可知，错误应是具体的，所以选D。
89.B参照上题，表示“不可能”的词组只有B符合be likely to do的搭配。 90.D参照88题，与原来错误的模型相反，当然是正确的模型。故答案为D。
