46. “Have you seen___ pen? I left it here this morning.” “Is it __black one? I found it in the corner.”

　A. a, the　　　 B. the, the　　 C. a, a　　　 D. the, a

这样一改，此题的最佳答案就是A，而不是C了

45. “Haveyou seen _____ pen? I left it here this morning.”　 “Is it _____ black one? I think I saw it somewhere.”　A. a, the　　 B. the, the　　 C. a, a　　 D. the, a

此题容易误选A，生搬硬套冠词用法规则：第一次提到某人或某事物用不定冠词，第二次再提到该人或该事物时用定冠词。但事实上，此题的第二空Is it black one?中的one并非指前面提到的pen，即这里的one与前面的pen并非同一事物。另外，从后面的I think I saw it somewhere(我想我在哪个地方见过)可知前一句的black one不能是特指的，而应是泛指的，故应用不定冠词。此题正确答案为C。

现在我们把此题变化一下：

44. Mother told Jim to watch the milk until it boiled and then _____ off the gas.　

　A. turn　　　 B. turning　　　 C. turned　　　 D. having turned

答案为A，turn off the gas与 watch the milk until it boiled并列。

43. They weren't a particularly good team, but they refused to give in and _____ defeat.

　A. accept　　　 B. accepted　 C. accepting　　　 D. to have accepted

此题容易误选B，误认为accepted与谓语refused并列。其实，最佳答案为A，动词accept与give并列。　

42. He was in great need of money, so he _____ $5, 000 for his car.　

　A. paid　　　 B. took　　　 C. cost　　　 D. spent

许多同学根据pay ... for ...这一搭配推断出此题应选A。但是错了，当然若单独说He paid $5 000 for the car (他付了5 000美元买这车)也没什么不妥，但问题是，本句前面有这样一句He was in great need of money (他急需要钱)，既然是“急需要钱”，又怎么还会花5 000美元去买车呢？尤其还需注意的是car前的物主代词his，这说明是为自己的车花5 000美元，不合情理。此题的正确答案是B，take在此表示“获得”，句意为“他急需要钱，把自己的车以5 000美元给卖掉了”。

41. _____ when one loses freedom does one know its value.　

　A. Just　　　　 B. Only　 　 C. Even　 　　　D. Ever　

此题最佳答案应选B，主要因为其后主句用了倒装句式(...does one know its value)，而综合所给四个选项，只有“only +状语”置于句首才会引出倒装句式。又如：

　Only in this way can you do it well.只有用这种办法你才能把它做好。

　Only by working hard can you succeed.你只有努力才能成功。

　Only yesterday did he return me the money.昨天他才把钱还给我。

　 Only after the accident did he have his car inspected.只有在那次事故之后，他才叫人检查了他的车子

40. Good luck to you, and _____ all your wishes come true!　

　A. can　　　　 B. may　　　 C. must　　　　 D. should 　

　答案选B，may置于句首可表示祝愿，又如：

　May you succeed.祝你成功。

　May God bless you.愿上帝保佑你。

　May you have a very happy married life.祝你的婚姻生活幸福美满。

39. Little Jim is going to spend his holiday in Paris, _____ lives his uncle.

　A. which　　　　 B. who　　 C. where　 　　　D. that　

许多同学一看到横线后的谓语动词lives，就以为横线处应填who，认为只有who与lives搭配才是合情合理的。但是错了，因为假若选who，那么who当然就是lives的主语，lives是句子谓语，那么his uncle呢？它是什么成分？是宾语吗？不可能，因为动词live为不及物动词，由此可知，选B是不对的。其实，此题的最佳答案应是C，where lives his uncle为倒装语序，此句可改为and there lives his uncle或and his uncle lives there。

38. The problem is not _____ easy. Think _____ over.

　A. such, it　　　　 B. that, it　　 C. so,不填　　　 D. that，不填

正确答案应为B，that相当与 so .

37. It is so difficult a problem that _____ student in this class _____ work it out.

　A. any, can't　　　　 B. no, can　　 C. every, can　　　 D. no, can't　

此题很容易误选A，因为从句意上看，选A可将此句理解为“这个问题是如此之难，这个班上任何一个学生都不可能做出来”。但按英语习惯，any(任何一个)作为非肯定词，它只能出现在否定词not之后，而不能在其前，即可说not any,但不说any not。所以正确答案应选B。这工作太难了，恐怕谁也干不了。

正：The work is too difficult. I'm afraid no one can do it.

　误：The work is too difficult. I'm afraid any one can't do it.

什么也阻碍不了我同她结婚。

　正：Nothing can prevent me from marrying her.

　误：Anything can't prevent me from marrying her.

　类似地，either (两者中的任意一个)作为非肯定词，它也应出现在否定词之后，而不能出现在否定词之前。如：这两兄弟都不聪明。

　正：Neither of the brothers is clever. / Neither brother is clever.

　误：Either of the brothers is not clever. / Either brother isn't clever.
