20、to indicate（分数：2.50）A.purpose.B.cause.C.direction.D.result.解析：解析 考查for的用法。for既可以作介词用，也可以作连词用。这里for作连词，引出原因，故答案为B。2._, he should be punished if he goes against the law.（分数：2.50）A.Whether the president or the citizenB.Was he the president or the citizenC.Be he the president or the citizenD.Were he the
21、 president or the citizen解析：解析 “be+主语+选择性表语”是让步状语从句的固定表达，意为“不管是还是”。故答案为C。A缺少主语和谓语，不能构成完整句子，D的倒装结构常用于虚拟条件句中，且一般不出现选择性词语or。3.It is generally believed that teaching is _ it is a science.（分数：2.50）A.as an art much asB.as much an art asC.an art much asD.much as an art as解析：解析 考查比较结构。as.as.中间可以接形容词或副词原形，也可
22、以接名词，结构如下：as+much+a/an+n. (可数名词单数)+as.，答案为B。4.Doris success lies in the fact _ she is cooperative and eager to learn from others.（分数：2.50）A.whenB.whyC.thatD.whether解析：解析 考查句子结构。that引导同位语从句，说明fact的内容，that在同位语从句中不作任何成分。其他选项填入此处都会使句子意思不通顺。5.You can never imagine that a well-educated gentleman _ be so r
23、ude to an old woman.（分数：2.50）A.mightB.shouldC.needD.would解析：解析 should作情态动词用时，除了表示推测、义务/责任、命令等，还可以用来表示某人对某事不能理解、感到意外、惊讶等意思，意为“竟然，竟会”，B为正确答案。6.John wants to visit me today. Id rather he _ tomorrow.（分数：2.50）A.cameB.comeC.are comingD.will come解析：解析 考查虚拟语气。would rather后面接从句时，表示主语宁愿某人做某事，从句要用虚拟语气，动词用一般过去式
24、，表示希望。注意区分would rather其他两个惯用句式：would rather do sth.“宁愿做某事”；would rather do.than do.“宁愿做而不愿做”。7.Mr. Wells has found some new clues in his investigation, _ of great importance to solve this criminal case.（分数：2.50）A.I think which isB.that I think isC.which I think isD.which I think it is解析：解析 非限定性定语从句用
25、法。在本句中，which引导了一个包含插入语I think的非限定性定语从句。A中which的位置不对，B中that不能引导非限定性定语从句，D中多了代词it。be of importance! 相当于be important。8.Susan is _ as an addlehead she always leaves her keys on the door.（分数：2.50）A.who is knownB.which is knownC.whom is knownD.what is known解析：解析 语法结构。本句中what为关系代词，引导一个名词性从句作表语，表示“那样的事物”。wh
26、at is known意为“所谓的，大家所知道的”。在表语从句中，who, whom和which不能既连接从句又充当从句中的主语或者宾语，故不选A、B、C。9.The harder the shrub is to grow, _.（分数：2.50）A.the higher is the priceB.the higher price it isC.the higher the price isD.the higher price it would be解析：解析 考查比较级结构。在“the+形容同/副词比较级+主谓结构，the+形容词/副词比较级+主谓结构”结构中，前者是后者发生的条件，表示前
27、后在程度上的相互一致性，答案为C。10.Old _ my grandpa is, he works like a young man.（分数：2.50）A.thatB.asC.whoD.like解析：解析 as引导让步状语从句的用法。as引导让步状语从句时，通常将让步成分(从句的补语/表语或状语)置于句首，形成倒装形式。当前置的让步成分是名词时，该名词前面不用限定词。如：Teacher as she is, she is not capable of teaching all subjects. though也有此用法，答案为B，其他选项不能引导让步状语从句。11.The housing pr
28、ice in big cities is _, but still many young people would rather buy a house than rent a room.（分数：2.50）A.sneakingB.soakingC.soaringD.spinning解析：12.He had a(n) _ when he entered the hotel that the gatekeeper was a detective.（分数：2.50）A.fantasyB.illusionC.imaginationD.vision解析：13.The campaign to stop p
29、eople from smoking is in full swing . The underlined part means（分数：2.50）A.progressB.vainC.issueD.terms解析：解析 短语in full swing的意思是“正在进行，正达到高潮”，它与A的意思一致。14.The _ law did not make a clear distinction between the new and old land boundary.（分数：2.50）A.adventurousB.advantageousC.ambitiousD.ambiguous解析：15.The
30、se contradictions made his evidence _.（分数：2.50）A.invaluableB.pricelessC.unworthyD.worthless解析：16.This band is set to _ their new album this fall.（分数：2.50）A.issueB.distributeC.publishD.release解析：17.So many people have bought this brand of bikes that the store is now out of _.（分数：2.50）A.reachB.stockC.
31、businessD.season解析：18.His _ brain and boundless energy drove him from one great invention to another.（分数：2.50）A.richB.quickC.productiveD.fertile解析：19.I was feeling dragged out so I went home. The underlined part means _.（分数：2.50）A.tediousB.coldC.sickD.exhausted解析：解析 短语dragged out的意思是“筋疲力尽”，这里与D意思一致。
32、20.I almost sing every song out of _ each time I try to hit the high notes.（分数：2.50）A.melodyB.musicC.tuneD.theme解析：解析 in/out of tune意为“和调/跑调”，因此选C。21.Which of the following sentences has a formal subject (形式主语)?（分数：2.50）A.It was 5 oclock when he came here.B.It is no use trying it again.C.It was yest
33、erday that I met her.D.I find it easy to get on with her.解析：解析 A中的it指时间，表语由具体的时间充当；B中的it是形式主语，真正的主语是分词短语trying it again，为本题答案；C中的it是强调句式；而D中的it是形式宾语，指代不定式to get on With her。22.A recent survey shows that most adolescents eat _ as they actually need every day.（分数：2.50）A.protein as three times muchB.th
34、ree times protein as muchC.three times as much proteinD.protein as much three times解析：解析 考查比较状语从句倍数的表达形式，即“倍数+as.as.”，答案为C。23.No sooner _ his speech than listeners put forward questions.（分数：2.50）A.he has finishedB.has he finishedC.he had finishedD.had he finished解析：解析 no sooner.than.是固定用法，意为“一就”，引导时
35、间状语从句，主句常用过去完成时，than后面的从句用一般过去时。题中的no sooner置于句首，因此需将助动词放在主语前面引起部分倒装，选D。24.Paul found it increasingly difficult to hear, _ his hearing was beginning to fail.（分数：2.50）A.andB.forC.butD.or解析：解析 his hearing Was beginning to fail是前一分句“听东西愈加困难”的原因，因此应选用可以表示原因的连词for引导原因状语从句。25._, she can now only stay at h
36、ome and imagine the atmosphere there.（分数：2.50）A.Not buying a ticket for the concertB.Not bought a ticket for the concertC.Not having bought a ticket for the concertD.Buying not a ticket for the concert解析：解析 考查分词作状语。题中主句的主语是she，-ing分词在句中作原因状语，与主语she之间有逻辑上的主动关系，不能选用表被动关系的过去分词。另外，分词的动作发生在前，主句的动作发生在后。因此
37、要用-ing分词的完成时态来表示，其否定形式是将not放在分词之前。综上所述，C为正确答案。A没有使用完成时态；B中过去分词表示这个动作与主句的主语是被动关系，不对；D没有用完成时态，并且错用了否定形式。26.Susan _ a book about cooking last year, but I dont know whether she has finished it.（分数：2.50）A.was writingB.has writtenC.wroteD.had written解析：解析 根据语境，不知道她现在是否写完了，可知苏珊去年“在写”关于烹饪的书，选A。若用一般过去时，则指苏珊“
38、写了”书，与后文相互矛盾，故排除。B、D选项在时态上也与后面的时态相矛盾。27.Mr. James is such a good teacher _ we all love and respect.（分数：2.50）A.asB.thatC.whomD.which解析：解析 定语从句引导词。在定语从句中，若先行词被such修饰时，关系词要用as，组成such.as.结构。此题容易误选B，以为是结果状语从句such.that.(如此以致)结构。如果后面的句子是we all love and respect her，则需用such.that.。28._ that it was going to ra
39、in, he took a raincoat with him.（分数：2.50）A.SeeingB.SawC.SeenD.To see解析：解析 分词作状语可表示时间、原因、方式或伴随情况等。现在分词作状语时，句中主语是该分词行为的逻辑主语；过去分词作状语时，句中主语是该分词行为的逻辑宾语。本句中he是发出“看”这个动作的主语，因此用现在分词。29.Andrew is _ than his students.（分数：2.50）A.more an experienced teacherB.a more experienced teacherC.an experienced more teach
40、erD.a teacher more experienced解析：解析 本题是两个人的比较，且比较的双方不属于同一类身份，因此修饰语more experienced不能放在名词teacher前，应后置，答案为D。该题若改为Andrew is _ than Tom，则选B，因为比较的双方身份相同。30.All of the plants now farmed on a large scale were developed from plants _ wild.（分数：2.50）A.that once grewB.once they grewC.they once grewD.once grew解
41、析：解析 介词后通常跟名词或名词性词组，由题干中的介词from可断定其后不能接完整句子，故排除B、C。that引导限制性定语从句，修饰plants，A为正确答案。先行词plants在定语从句中作主语。关系代词不可省略，所以D缺少关系代词，不能选。31.Fred and Betty finally decided to tie the knot . The underlined part means _.（分数：2.50）A.get marriedB.have a childC.separateD.compromise解析：解析 短语tie the knot的意思是“结婚”，即A。32.The
42、same thing said in a different _ will convey a different message.（分数：2.50）A.accentB.toneC.dialectD.rhythm解析：33.Joyce was a little _ about whether he would marry her or not.（分数：2.50）A.dimB.ambiguousC.obscureD.vague解析：解析 be vague about表示“不清楚”，其他选项均不与about搭配。34.This article focuses on the minor matters
43、 that job seekers often _.（分数：2.50）A.ignoreB.neglectC.omitD.overlook解析：35.It was _ that the school discriminated against Asian students.（分数：2.50）A.assaultedB.allegedC.addictedD.ascribed解析：36.Native American artwork and artifacts have been _ collected and studied abroad for a number of years.（分数：2.50
44、）A.periodicallyB.thoroughlyC.systematicallyD.enthusiastically解析：37.The scientists have absolute freedom as to what research they think is best to _.（分数：2.50）A.pursueB.devoteC.engageD.seek解析：38.Its hard to change many Americans _ view that Germans lack a sense of humor and are always buried in work.（分数：2.50）A.stereotypicalB.religiousC.traditionalD.orthodox
