18、，即以 reasons for which.的形式出现，也是正确答案；选项 D 的 how 不可以引导定语从句。3.Broadband (宽带) connections are widely available now, _ makes online shopping much easier.（分数：2.50）A.whatB.whateverC.whoD.which 解析：解析 本题考查非限制性定语从句的引导词。空格前的逗号表明，后半句应为非限制性定语从句，空格处应填入引导词。故正确答案为选项 D。4.The manager decided to continue the sales for

19、_ two weeks because of the large stock of goods.（分数：2.50）A.otherB.another C.the otherD.others解析：解析 本题考查 other 和 another 的用法辨析。依句意可知，本题空格处和后面的 two weeks 连起来，表示“多两周”的意思。another+数字，表示“多几个”的意思，故正确答案为选项 B。other 通常与 the，some，any 连用；而 others 的意思与“other+复数名词”相同，其后不接名词；the other 后可接单数或复数名词，通常翻译为“其余的”的意思。5.We

20、 don“t have to hurry as the bus _ for London at five in the evening.（分数：2.50）A.leaves B.leftC.has been leavingD.has left解析：解析 本题考查动词时态。本题中的 as 引导原因状语从句，表明“不用匆匆忙忙”的原因是车在5 点才开往伦敦。发车时间通常是一种常态化的安排，所以动词 leave 应使用一般现在时，表示习惯性动作，故正确答案为选项 A。6._ great losses in the financial crisis, the company closed down la

21、st year.（分数：2.50）A.Being sufferedB.To sufferC.Having suffered D.Suffered解析：解析 本题考查-ing 分词作状语。本句中句子主语 the company 于动词 suffer 构成主动关系，suffer 和主句动词 close down 在时间上存在先后的关系，故 suffer。用作分词状语时应使用现在完成式having suffered，正确答案为选项 C。7.Last week two engineers _ to help solve the technical problems of the project.（分数

22、：2.50）A.have sentB.were sent C.sentD.had sent解析：解析 本题考查被动语态的用法。空格处应填入句子的谓语，经分析可知，句子主语 two engineers 与动词 send 应为被动关系，故正确答案为选项 B。8.You have to work in this position for two years _ getting promoted.（分数：2.50）A.onB.sinceC.withD.before 解析：解析 本题考查介词。经分析可知，空格处应填表明时间的介词，并且表示 work(工作)和 get promoted(得到升迁)之间的先

25、a big project can not be made _ each member of the board agrees.（分数：2.50）A.ifB.unless C.thoughD.as解析：解析 本题考查状语从句连词的用法。根据空格处前后的句义可以判断，此处需要一个引导条件状语从句的连词，从句是条件，主句是结果。在四个选项中，选项 A 和选项 B 都可用于引导条件状语从句，选项 B 的 unless 等同于 if.not，与选项 A 的意思刚好相反，适合本句句义。故答案为 B。选项 C 通常用于引导让步状语从句，选项 D 可以用于引导时间状语从句和原因状语从句，这两个选项都不能正确

26、地表达此处主从句之间的逻辑关系。12.There was no proof to show that Charles had committed the crime, _ he was set free.（分数：2.50）A.butB.forC.orD.so 解析：解析 本题考查并列句连词的用法。从空格处前后两个并列句的句义可以判断此处需要一个表示因果关系的连词，而且是引出“结果”的连词，即第一个分句是因，第二个分句是果，在四个选项中，能引出“结果”的连词是选项 D。选项 A 是表转折关系的连词，选项 C 表选择关系的连词，不符合原文需要表达的逻辑关系；选项 B 表因果关系，但 for 引出的

27、分句是因，而不是果。13.Medical accidents _ by drugs have attracted much attention in that country.（分数：2.50）A.causingB.to be causedC.be causedD.caused 解析：解析 本题考查非谓语动词作定语的用法。空格处后的 by 提示空格前的名词 Medical accidents与动词 cause 应该构成被动的关系，即 cause 应为其过去分词形式，表示“医疗事故”是“由药品引发”的，因此，选项 D 为正确答案。14.No sooner _ than I realized I“

35、 home, partly because of (have) 1 to wear special glasses. （分数：2.50）解析：having解析 本题考查介词宾语的形式。空格处前的 because of 后应为表示原因的介词词组，形式为动词的-ing，故正确答案为 have 的动名词形式 having。26.Those who get nervous (easy) 1 may try Taiji, which relaxes the mind and strengthens the body. （分数：2.50）解析：easily解析 本题考查形容词、副词互相转化。空格处前后有完

40、 were iron and steel, and medical instruments. （分数：2.50）解析：imported解析 本题考查非谓语动词作定语的用法。句中谓语部分已有 were 一词，故空格处不是动词的谓语形式，而是对 major products 起到修饰作用的非谓语动词。而空格后的 by 表明，空格处应为这个非谓语动词的被动形式，表示“被马来西亚进口的”商品，因此，应将提供的动词 import 改写为过去分词 imported，作为 major products 的后置定语。33.Business and professional services (list) 1

41、in the Yellow Pages. （分数：2.50）解析：are listed解析 本题考查动词的被动形式。本句没有谓语，复合主语 business and professional services 都是必须由人来提供的，据此可判定主语与动词 list 应构成被动关系。句子虽然没有明显的时间标记，但说到“黄页”，应该属于日常习惯性的状态，动词应用一般现在时。因此，应将提供的动词 list 改为 are listed。34.Nokia“s mobile phone market share in China (fall) 1 to its lowest level since 2005

42、. （分数：2.50）解析：has fallen解析 本题考查动词时态。本句子没有谓语，句末的 since 2005 是一个搭配现在完成时的时间状语，这表明句子所需的谓语动词应为现在完成时；又因为句子的主语核心词是 share，为单数名词，可知答案为 has fallen。35.To her (disappoint) 1, the girl was denied the job she had applied for. （分数：2.50）解析：disappointment解析 本题考查动词、名词互相转化。空格前的 her 表明空格应为名词，因此应将 disappoint 通过加词尾-ment

43、转化为其名词形式 disappointment。36.While (study) 1 at college, he got to know the professor and learned a lot from him. （分数：2.50）解析：studying解析 本题考查动词的分词形式。while 意为“在的时候”，引导从句时如果主句和从句的主语一致，可以省略从句主语及系动词，直接加 doing sth. 作伴随状语。故答案为 studying。37.Communication via eye contact seems to be (particular) 1 important in

44、 some cases. （分数：2.50）解析：particularly解析 本题考查形容词、副词的转化。空格前后的 be 和 important 可以构成完整的谓语成分，由此可知空格处应为修饰 important 程度的副词，因此应将形容词 particular 转化为副词形式 particularly。38.As more customers will attend the meeting, we need to prepare some (addition) 1 chairs. （分数：2.50）解析：additional解析 本题考查名词、形容词相互转化。空格后的名词 chairs
