10、 语法 3 【正确答案】 D 【试题解析】 由 “eitheror” 引导的成分要对等。 A虽然结构上可选,但句中已有 hardly,所以句意不合适。 【知识模块】 语法 4 【正确答案】 B 【试题解析】 for引导带逻辑主语的不定式 for sb to do sth,本句中的 there作形式主语;不定式就是 to be a frost。如: “该吃药了 ”应说: Its time to take the medicine如果要说 “他在等到该吃药的时间再吃药 ”就应说: Hes waiting for it to be time to take the medicine 【知识模 块】

11、语法 5 【正确答案】 D 【试题解析】 leave后面跟带现在分词的复合结构。 【知识模块】 语法 6 【正确答案】 A 【试题解析】 expect后面跟带不定式的复合结构 expect sb to do sth;如果要表示 “预料在将来某个时间某人会做完某事 ”就应说 expect sb to have done sth (后面跟一个表示时间的状语 ),因此变为被动态就成了本题的 commercial air traffic is expected to have extended vastly beyond todays levels。 【知识模块】 语法 7 【正确答案】 B 【试题解

12、析】 much of what they must learn in a course意为 “他们在一门课程中所必须学到的很多东西 ”。 【知识模块】 语法 8 【正确答案】 B 【试题解析】 to base sth on sth else意为 “把 建立在 的基础上 ”,介词on在本题中提到了从句句首, which为关系代词,代替前面的先行词 grounds,意为 “理 由,根据 ”。 【知识模块】 语法 9 【正确答案】 C 【试题解析】 as we had expected意为 “正如我们所预料的那样 ”,有的语法书将as分析为关系代词,代替主句所谈的情况,这样用的 as从句既可以放在主

13、句之后,也可以放在主句之前,但作关系代词用的 that which who只能放在先行词之后。 【知识模块】 语法 10 【正确答案】 D 【试题解析】 know better than to do sth =be wise enough not to do sth意为“懂得不该 ;非常精明不至于做 (某种蠢事 )”。 should have known better than to ask Dick for help意为 “应懂得不该向迪克请求帮助 ”。 【知识模块】 语法 11 【正确答案】 B 【试题解析】 how what they have observed can be used

14、in other contexts意为 “如何将他们所观察到的应用于其他情况 ”, what they have observed作宾语从句的主语, how引出宾语从句,其他三 个选项不合适。 【知识模块】 语法 12 【正确答案】 A 【试题解析】 find后面可以跟现在分词或过去分词的复合结构。本题中的 found it being cultivated是跟现在分词的被动态。 【知识模块】 语法 13 【正确答案】 B 【试题解析】 本题测试虚拟语气。名词 requirement的同位语从句或表语从句的谓语需用虚拟语气 should+动词原形, should可省略。 【知识模块】 语法 1

15、4 【正确答案】 D 【试题解析】 Much as he likes her意为 “尽管他很喜欢她 ”。 much as+主语 +谓语(表示爱憎的动词 )表示 “尽管 ” ,起让步状语从句的作用,相当于 although从句,如: Much as I would like to come, I cant Much as she hated cruelty, she couldnt help watching the fight其他表示让步的类似结构还有: “形容词 (或副词 )+as+主语 +谓语 (be动词 )”; “Come what may”; “Try as one will would”; “形容词 (或副词 )+though+主语 +谓语 ”等。 【知识模块】 语法 15 【正确答案】 C 【试题解析】 be familiar with意为 “熟悉 ”,主要指的是人对某人或某事熟悉。 be familiar to意为 “被某人熟悉 ”,主语一般是事情、事物等。本题中讲的是我们最熟悉的数学符号,主语是人,因此用 be familiar with,介词 with移到 which引导的从句前。因此本题答案为 C。 【知识模块】 语法
