Answer 1

46. A container weighs more after air is put in, it proves that air has weight.more->heavier重量不用many的，而应该用heavy，比较级就是hezvier
A B C D
47. The young man, to make several attempts to beat the world record
A B
in high jumping, decided to have another try. to make->making（现在分词表状态，表示动作发起者正在做的事。而to do表示为了做什么，不符题意。）
C D
48. Of the two coats, I'd choose the cheapest one to spare some
A B C
money for a book. cheapest->cheaper（两者之间，不用最高级，只能用比较级。）
D
49. The protection of our environment is not nothing to be left to the
A B C
government. Everyone should be concerned. (to be去掉，不太确定，这句话意思不太懂，不好意思。)
D
50. There are moments in life where you miss someone so much that
A B C
you just want to pick them up from dreams and hug them for real.
D where->when（明显moments是表时间的，不能用which的）
51. None of us had the final say in this matter, and therefore it was
A B C
recommended that we waited for the authorities.
D waited->wait（参见recommend的用法，上例是典型用法，常见短语，需要记住的。）
52. After her two-week vacation was over, Dorothy regretted to spend
A B C
so much money for so little pleasure. to spend->having spent
D
53. Don't make Helen's remarks too seriously. She is so upset that I
A B C
don't think she really knows what she is saying. make->take（take sth seriously固定短语，拿……当真的意思。）
D
54. Workers newly arrive from the south or rural areas perform their job
A B
differently from those from other sections of the city.
C D job->jobs（这题arrive那边感觉也有点不对，不过相较来看job这个错误有点明显，所以最终还是决定选它，不知道是不是题目打错了。）
55. While remembered mainly for the invention of the telephone,
A B C
Alexander Graham Bell devoted his life to help the deaf.
D help->helping （这个也是固定用法，devote oneself into doing sth具体的可以查字典看看devote用法。）
