2. 解析:选D。考查动词辨析。句意为：我们不得不一遍又一遍的向学生解释捐一美元还是二十美元并不重要。向学生“宣告”(announce)、“保证”(guarantee)，意思显然不对，故排除A、C两项；clarify澄清、阐明，也不符合句意，并且与后面的over and over矛盾。故选explain(解释)。
2. 解析：选C。考查固定搭配。owe sth. to sb./sth.意为“把……归功/归因于……”。句意为：这位年轻的作家把他的成功归因于他老师的鼓励。
3. 解析：选D。考查动词短语辨析。go against违背，相反；care about关心；fight for为……而战；take up 从事。句意为：如果人类违背自然的规律，迟早会遭受痛苦的。根据句意可知，选D。
4. 解析：选D。no wonder意为“难怪……”，也可以用It is no wonder...句式。句意为：“他都三天没睡觉了。”“难怪他那么疲劳。”
5. 解析：选C。考查词义辨析。transform意为“转换，改变”。句意为：他的志向是改变整个社会，让我们过上更美好的生活。
6. 解析：选D。make out在句中意为“弄明白，理解”。句意为：“你为什么不继续工作？”“因为这个问题让我很迷惑，我需要先把它弄明白。”
7. 解析：选B。考查含有not ...until的强调结构。“It wasn?t until ...that ...”，主句和从句都用陈述语气。句意为:直到老师进来，学生们才开始准备功课。
8. 解析：选C。先行词situation(情况；情形)在定语从句中作地点状语，故选择关系副词where。
9. 解析：选C。由句中的标点符号可知,此句是主从复合句，故排除B、D两项。特指“两者中比较……”应用“the+比较级+of...”。此处 the smaller of which引导定语从句。
10. 解析：选A。考查情景交际用语。be on close terms with sb.表示“与某人关系很好”。
5. He would not go against his parents’wishes.
