Question

【题目】Kangkang usually _____ his homework at 7:00 p. m, but yesterday he started _____ it at 8:00 p. m.
A.do; doing
B.does; do
C.does; doing
D.do; do

Answer 1

【答案】C
【解析】句意：康康通常在晚上7点做作业，但是昨天他8点才开始做。根据题干第一句中usually可知应使用一般现在时，而Kangkang作主语属第三人称单数，应用does。第二句使用了短语start doing/to do sth，“开始做某事”。故选C。
