61. D 本题考查省略句的用法。此处完整的句子应为：This problem may lead to more serious ones if it is left unsolved. 在从句中如果主语与主句的主语一致时，常将从句的主语和谓语的一部分省略。
62. C 本题考查短语的用法区别。rather than的意思是“是……不是……”. “宁愿……而不愿……”，more than的意思为“超过. 不仅”，other than的意思是“除了”，less than的意思是“少于. 决不”。在此处只有选项C最符合本句意义：除了梦想过上好生活，我没有别的梦想了。
63. C any better意为好了一点，符合日常生活对话情景。much better. no better虽符合语法，但不符合该题语境。
64. C cover=be enough for sth. 易误选D，meet支付. 偿付（某费用，主语一般为人）。
65. B make sb. into sb. 将某人变成某人
66. D before在本句中意为rather than sth
67. A sort of达到某种程度
68. A 本题考查动词在具体语境中的意义。promise在此处的意思为“预示会成为”，其他三个选项的动词意义与本题语境不符。
69. C 本题考查连词的用法。由语境分析可知，此处表达的意思为“在公共汽车将要停止的过程中不能下车”，能表达此意的连词只有while，表示“在……过程中”
70. B 本题考查情态动词的用法。由句中的years ago可知这里是对过去发生事情的揣测，因此应用could have imagined。
