15、 up_ special speech sounds are recognized by babies as young as six months old.（分数：1.00）A.whatB.that C.whichD.whose解析：came up 在本句的意思是“结果是”。空白处填入 that 后，实际上构成了 evidence 的同位语从句，由于句子的主语太长，根据“尾重”的原则，将同位语从句部分放在谓语之后。what 若放在句中空格处，句子结构不能成立。因为 what 引导名词性从句时总是在句中担当一定的成分。如：I dont know what he wrote in his let

16、ter我不知道他在信里写了些什么。(宾语)What calls for our concern is that pollution has greatly affected our lives值得我们关注的是，污染已经严重影响了我的生活。(主语) 而在题干中，空白之后的被动句主谓皆齐全，what 无适当成分可充当，因此不是正确答案。选项 C 和 D只能使空白以后部分变成定语从句，这样全句的意思就讲不通了。2.I“m glad to say that he“s already finished _ 50% of the book in these past three days.（分数：1.00

17、）A.no less than B.no more thanC.not more thanD.much less than解析：3.So little _ about physics that the lecture was completely beyond me.（分数：1.00）A.I knewB.did I know C.I had knownD.had I known解析：解析 倒装结构 so+形容词/副词置于句首，句子要用到部分倒装，即把助动词、系动词或情态动词放到主语之前。因此答案是 B)，A)不正确。 so.that 句型中动作没有明显的前后，一般时态要保持一致，所以不用 ha

18、d，答案 C)和 D)不正确。4.She is the only one of those girls who _ willing to do that voluntary job.（分数：1.00）A.areB.wereC.wasD.is 解析：解析 本题考查主谓一致。在“one of+复数名词+定语从句”结构中，当 one of 前面有 the only 修饰时，定语从句中的谓语动词应用单数形式，又因为主句使用的是一般现在时，所以 who 后面的谓语动词应为一般现在式，故答案为 D。5.I have the same trouble _ you have.（分数：1.00）A.thatB.

19、whichC.as D.what解析：as 引导定语从句，当先行词受 such 或 the same 修饰时，关系词常用 as。6.The young singer _ sang Colors of the Wind won the first prize in the contest.（分数：0.50）A.of whomB.whoseC.who D.whom解析：7.I“ll lend you my computer _ you promise to take care of it.（分数：1.00）A.unlessB.whileC.asD.if 解析：8._, her mother wil

20、l wait for her to have dinner together.（分数：1.00）A.However late is sheB.However is she lateC.However she is lateD.However late she is 解析：however 后接形容词或副词，表示“无论”，用于句首需倒装；但若句子主语是代词，则不用倒装，所以选 D。句意：无论她多晚回来，她妈妈总会等她一起吃饭。9.She didn“t go to the cinema last night, _ she had to finish her term paper.（分数：1.00）A

21、.as B.ifC.tillD.though解析：她昨晚没有去看电影，因为她不得不完成她的学期论文。本题中主要需要一个引导原因状语从句的词，这几个词中只有 as 有这个用法，所以答案选 A。10.Either you or Lin Ming _ supposed to do the job.（分数：1.00）A.areB.beC.beingD.is 解析：11.The true value of life is not in _, but（分数：1.00）A.which we get; what give weB.what we get; what we give C.which do we

22、get; what do we giveD.how we get; that we give解析：解析 句子意思是：生活的真正价值不在于我们得到什么，而在于我们给予什么。what 引导的名词性从句作介词 in 的宾语从句。12.He told me that _ nothing there was worth looking into.（分数：1.00）A.nearlyB.almost C.hardlyD.seldom解析：13.This question is very difficult, _ of the students can answer it.（分数：1.00）A.BothB.A

23、llC.NeitherD.None 解析：14.In order to improve your communication skills, we will show you how to learn _ about your customers than you know now.（分数：1.00）A.manyB.muchC.mostD.more 解析：解析 句子意思是：为了提高你的交流能力，我们将教你如何更多地了解你的客户。看到句子后面有单词 than，就应想到用比较级。15.He has the occasional cigarette, but _ he smokes a pipe t

24、hat is more harmful to his health.（分数：1.00）A.mostB.nearly C.mostlyD.almost解析：mostly 表示“大多情况，多数地”，most 作副词，表示“非常”，nearly 和 almost 表示“几乎”。根据句意，应选 B。意为：他偶而吸吸烟，多数时候是抽烟斗，这对他的健康更有害。16.By the end of this year, Mr. Smith _ in our company for exactly three years.（分数：1.00）A.is workingB.has workedC.will workD.

25、will have worked 解析：解析 本题考查动词时态，由状语“by the end of this year”可知本题应用将来完成时。17._, water should be regarded with caution as it can be dangerous.（分数：1.00）A.Beautiful as it is B.It is beautifulC.As it is beautifulD.Beautiful it is解析：解析 考点：倒装。此句是倒装用于“形容词(或名词、动词)+as(though)”引导的让步状语从句中。如果从句的表语是名词，其名词前不加任何冠词。

26、例句 Pretty as she is，she is not clever 她虽然很漂亮，但是不聪明。 Child as he was，he had to make a living 他虽然是个孩子，但他不得不去谋生。 18.You have to work in this position for two years _ getting promoted.（分数：1.00）A.onB.sinceC.withD.before 解析：考点 介词 解析 本句的意思是：你必须在这个岗位上工作两年才能获得晋升。19.The company _ next year is an electric equi

27、pment manufacturer.（分数：1.00）A.to be built B.being builtC.builtD.having built解析：解析 考查不定式。此不定式的被动式用作定语，修饰前面的名词。不定式表示将来的概念。20._ my hand, please!（分数：1.00）A.Let go of B.Let outC.Let offD.Let down解析：解析 此句意为：请放开我的手。 此题的考点是固定词组的用法。let go of sth.表示“松开，放开某物”。let out 意为“泄露(秘密)；放出(水，汽)”等；let off 意为“让下车；放(烟火)”等，

28、let down 意为“放下，降下”。根据句意可知，本题的正确答案为 A)。 由 let go 构成的词组很多，如： let.alone 不干涉，听之任之，更不必说。如：The baby can“t even walk，let alone run.这个婴儿还不会走路，更不要说跑了。 let.be 不干涉，听之任之。如：Just let it be!随它去吧 1 let.down 使失望，放下。如：Please don“t let me down.请别让我失望。 let.go 释放，松手。如：Let go of me!放我走！ let.in 放进来。如：Windows let in light

29、and air 窗户让空气和光进入。 let.off 放(炮、烟花、枪等)。如：Shall we let off the fireworks now?我们可以现在放烟花吗？ let.out 泄漏，放掉(水、气等)，释放。如：The old lady let out a deep sigh.老妇人长长地叹了口气。三、Section B(总题数：20，分数：22.00)21.He said that they were looking forward (do) 1business with my company. （分数：1.00）解析：to doing 解析 本题考查固定搭配中介词的用法。loo

30、k forward to 是固定结构，表示“盼望”的意思，其中 to 是介词，需要和动名词搭配使用，因此用 to doing。 学习中需要掌握常见的 to 为介词的词组，如 object to，agree to 等。22.He was often (patient) 1 with his employee and as a result they decided not to work for him any longer. （分数：1.00）解析：impatient。 解析 词形转换 此处空格为 was 的表语，又因为 as a result 引起的句子表示的是否定意思，所以应该用其表示否定

31、意思的形容词形式23.Our environment (get) 1 worse and worse with the increase of the world“s population. （分数：1.00）解析：is getting解析 本题测试的是动词时态的用法。句意：随着世界人口的增加，我们的环境正变得越来越糟。24.What a (self) 1 girl you are; let the other children share your toys. （分数：1.00）解析：selfish 考点 词性转换 解析 根据句意，不定冠词 a 和名词 girl 之间应填形容词。25.I“v

32、e been reading a mystery story. Many (mystery) 1 events took place in it. （分数：2.00）解析：mysterious 考点 词性转换 解析 根据句意，该题需用一个形容词来修饰名词 events，所以需要填写 mystery 的形容词形式mysterious。26.Do the results of the study have any practical (apply) 1? （分数：1.00）解析：application“运用”，用其名词形式，加后缀-ation。27.Bread and butter (be) 1

33、my favorite breakfast. （分数：1.00）解析：is 解析 主谓一致 由 and 连接两个或两个以上的单数名词作主语，如果指同一概念，谓语动词用单数。而且本题没有具体的时间，应该是一般陈述，要用一般现在时。28.He will never forget (meet) 1 Chairman Mao in Beijing. （分数：1.00）解析：meeting解析 他从不会忘记在北京见过毛主席。forget doing sth意为“忘记做过某事”。29.Your 1 (strong) is the physical energy that you have, which g

34、ives you the ability to perform various actions, such as lifting or moving things. （分数：1.00）解析：strength解析 句子意思是：你的力量是指你拥有的体能，它使你能够完成各种各样的动作，比如举起或移动东西。填入的单词应该是名词，作句子的主语。strong 是形容词，其名词形式是strength，意思是“力量、力气、强度”等。30.The customers made (complain) 1 about the high prices. （分数：1.00）解析：complaints 名词作宾语。31.

35、Both Marx and Engels were 1(German). （分数：1.00）解析：Germans解析 马克思和恩格斯都是德国人。用复数形式。32.All the books are on sales in the bookstore. It is too good a chance (miss) 1. （分数：2.00）解析：to miss解析 too.to.表示“太而不能”，所以空格处应填入 to miss。33.Shall we(meet) 1 at the school gate? （分数：1.00）解析：meet解析 本题考查 shall 的用法。shall 作为助动词

36、一般用于第一人称 I 和 we, 表示一个将来的动作, 其后动词应用动词原形。34.Companies need to take (action) 1 steps to increase exports. （分数：1.00）解析：active 解析 本题考查形容词的用法。留空处介于动词 take 和名词 steps 之间，因此可以判断steps 是动词 take 的宾语，而名词之前需要形容词修饰，所以此处使用 action 的形容词形式 active。 在解答此类题时，关键是要能正确判断出留空处需要何种词性的单词。35.I don“t think it worthwhile (spend) 1

37、 tens of thousands of dollars on the furniture. （分数：1.00）解析：spending 解析 本题考查固定结构的用法。worthwhile 是形容词，通常使用 it be worthwhile doing sth.的结构，因此此处需要动词的-ing 形式，即 spending。 需要注意的是 worth，worthy 和 worthwhile 几个近义词的用法差别。请注意区分以下几个结构的差别：sth.be worth doing；sth. be worthy of sth.，to do sth.；it be worthwhile doing

38、sth.。36.He got (kill) 1 by the bus. （分数：1.00）解析：killed解析 他被公共汽车撞死了。get 型被动态后面动词用过去分词。37.This is a (health) 1 place-fresh air, plenty of sunshine and clean water. （分数：1.00）解析：healthful解析 本句中需要一个形容词修饰名词 place，作定语，名词 health 有两个形容词，分别为 healthy 和 healthful，其中 healthy 意为“健康的”，healthful 意为“有益于健康的”，根据句意，应该选

39、择 healthful。38.If he 1 (be) here last night, I would have spoken to him. （分数：1.00）解析：had been 解析 考点：虚拟语气。此题考查与过去事实相反的假设，主句用“should (would) have+过去分词”，条件从句用过去完成时。 例句 If my lawyer had been here last Saturday，he would have prevented me from going 如果我的律师上个星期六来，他就不会让我去了。39.Tourism has (ruinous) 1 this on

40、ce unspoiled forest. （分数：1.00）解析：ruined 本题考点是词性转换。在句中作谓语，用动词。本句大意：旅游业已经毁掉了这个以前未被破坏过的森林。40.People who (residence) 1 inside the city make up 60 percent of the population. （分数：1.00）解析：reside 解析 本题考查主谓一致的问题。定语从句中缺少谓语，说明空格处需要动词，主句时态是一般现在时，所以从句时态应保持一致，也用一般现在时；又因为主语 people 一般作为复数名词，所以动词用原形 reside。 动词的转换形式较多，要考虑以下几个问题：1)动词在句中的语法成分，谓语或非谓语动词。2)如果是谓语动词，考虑动词的时态、语态和主谓一致问题；如果是非谓语动词，考虑是现在分词还是过去分词。
