选择题
To celebrate the New Year, the students stayed in the classroom after school, _____ the performances and ______ the room.
A．practicing ; preparing
B．practiced ; prepared
C．to practise ; prepare
D．practicing ; prepared
答案
答案：A
考查非谓语动词。句意“为了庆祝新年，学生放学后待在教室里，练习节目，布置教室。”the students和practice与prepare是主谓关系，应该用主动形式，表示伴随状况。故选A。
