46. Hardly I had sat down when I heard someone knock at the door.

47. Nobody believed that his excuse for being late was why his car broke
A B C D
down on his way to work.
答案为C。why应改为that. the excuse was that…/理由是…(相似结构： the reason is that…)
48. I wish I finished writing the essay yesterday, but I was too busy.
A B C D
答案为B。 finished应改为had finished. 题干中出现了时间状语yesterday，因此从句谓语应使用过去完成时态，表达与过去的事实相反的愿望。（昨天的课程里专门讲了wish和hope的不同： wish + that从句（从句谓语要使用虚拟语气，表示与事实相反的愿望或实现可能性很小的愿望）
49. Tom’s father, as well as his mother, ask him to stay in New York for a
A B C
few more days.
D
答案为 B。 ask应改为asked或has asked. 该题考主谓一致性。 as well as前面出现句子真正的主语。(昨晚的语法补充资料中强调了这个考点)
50. After … afew weeks with him, I felt sorry for to be unfriendly to him at first.
A B C D
答案为C。 to be应改为being. 介词后面应该出现名词/动名词/代词作介词的宾语。
51. Robert is a great basketball fan and love Kobe Bryant very much.
A B C D
答案为C。 love应改为loves. 考点为and连接的并列结构应该具有相同的语法特征: is与love并列，共同作句子谓语，都应以第三人称单数的形式出现。（辨错题复习资料）
52. The puzzle was so difficult that I gave up it in the end.
A B C D
答案为C。 gave up it应改为gave it up. 宾语为代词时要出现在动词 + 副词的短语中动词的后面，副词的前面。做题口诀: 代词不常是考点，代词一旦带划线，代词可能是答案（辨错题复习资料）。
53.In March when spring is already here, we usually plant many young trees
A B
on both side of the street.
C D
答案为D。 side应改为sides. both表示两者，因此side应以复数形式出现。（昨天下午的课里专门讲了该考点）
54. You’d better to go home now because it’s going to rain in no time.
A B C D
答案为A. to go应改为go. had better do…这个结构在翻译资料中专门给了。
55. After they reached the top of the mountain, they felt extremely hungrily and
A B C
thirty.
D
答案为C。 hungrily应改为hungry. 该题再次考到了并列结构的结构特点，也考查了形容词跟在系动词/半系动词后做表语。
