第一节单项填空
21. The "Chinese Dream" is ____ dream to improve people's well-being and ____ dream of harmony, peace and development.
A. the; a B. a; a C. a; the D. the; the
21. B。本题考查冠词的用法。第一个dream为泛指，用不定冠词；第二个dream与第一个dream是并列关系，也是泛指，也用不定冠词。
【句意】中国梦是一个提高人们的幸福感的梦想，是一个和谐、和平和发展的梦想。
22. _____ basic first-aid techniques will help you respond quickly to emergencies.
A. Known B. Having known C. Knowing D. Being known
22. C。本题考查非谓语动词。will help是句子的谓语部分，_____ basic first-aid techniques是句子的主语部分，起逻辑主语是you，与Known构成主动关系，所以用动词-ing做主语。D是被动关系。
【句意】掌握基本的急救技能将会有助于你在遇到紧急情况时迅速做出反应。
23. The famous musician, as well as his students, ____ to perform at the opening ceremony of the 2012 Taipei Flower Expo.
A. were invited B. was invited C. have been invited D. has been invited
23. B。本题考查主谓一致。主语是单数，尽管后面跟有介词或介词词组作附属修饰语，谓语动词仍用单数形式。排除A和C；2012 Taipei Flower Expo是一个过去的时间，动作已经发生，和现在没有关系，没必要用现在完成时，排除D。
【句意】这个著名的音乐家和他的学生被邀请在2012年的台北花展上演出。
