Ⅰ.单项填空
1．Be quiet! Do you hear someone ________ for something?
A．shouting B．shout
C．to shout D．shouted
答案：A 考查非谓语动词形式。根据someone与shout的主动关系排除D项。hear后接不定式作宾语补足语时应省略to，由此排除C项。由Be quiet可判断此处表示动作正在进行，故选A项。
2．Sitting in the chair beside the window, I watched the leaves ________ in the wind.
A．swinging B．hitting
C．striking D．knocking
答案：A 考查非谓语动词形式。watch为感官动词，后接动词作宾语补足语时用现在分词表示“正在……”。swing摇摆；hit重重地打、击；knock用力撞击；strike用木棒、石头等的猛然敲击，与hit用法接近。此处指树叶正在风中摇摆，所以选A。
3．(2014·合肥高一检测) I was greatly ________ at how he worked out the ________ problem in a creative way.
A．amazed；puzzled B．amazing; puzzling
C．amazed; puzzling D．amazing; puzzled
答案：C 考查非谓语动词。句意：他很有创意地把这个令人困惑的难题解决了，我对此惊诧不已。be amazed at对……感到惊异；puzzling令人迷惑的。
