【答案详解】
21. B just my luck是习语，意思为“真倒霉!”。not at all和that's all right多用于对方感谢时的应答语，“不客气”。Never mind用于对方道歉时的应答语，“没关系”。
22. A 这是一个省略句，承接上文，省略了as I had thought。
23. C 本题主要是对句子结构及关系是考查。根据逗号可知，后面句子为非限制性定语从句，先行词是plan;再根据句子中的was及前面的two可知本题的正确答案为C。
24. C 本题主要考查非谓语动词的用法。根据句意可知句子空白处的非谓语动词作定语，用have sb. /sth. to do的结构。
25. A 本题主要是对副词的考查。that作副词时，相当于so，强调所指的某一程度;much作副词时，一般只用来修饰形容词或副词的比较级及动词;enough作副词时，总是用在谓语所修饰的形容词或副词之后;too作副词时，强调事物的程度已超出某范围，让人难以应付。
26. C 本题主要考查反意疑问句的表达方式。根据listen可知，must be quarrelling表示推测，此时反意疑问句中的动词须依主语而定，由于his family是指他家里的人，故be用复数形式。
27. D 本题主要考查冠词的用法。句子第一空后面的不定式做定语对power进行修饰，特指某种权力，用定冠词the;而第二空后面的law泛指“法律”这一概念，不用冠词。
28. C 本题主要考查介词的用法区别。根据句子中的felt unhappy可知，句子中表示一种心理状态，于是，正确答案为C。
29. D 本题主要考查名词的意义区别。根据后面的resulted in failure可知，她没有专心于工作，而keep one's mind on意思为“专心于”，于是正确答案为D。
30. A 本题主要考查英语交际用语的应用。根据对方的话“I'm sorry for her”表示对她的关心，于是回答应该用“谢谢”，因此正确答案为A。
