The student’s behavior cost the teacher a steepless night . He never thought his student ______ computer games for a whole class .
A．played
B．was playing
C．had been playing
D．would play
答案
答案：C
考查动词的时态。主句谓语动词thought是一般过去时态，所以从句谓语用过去时态的某种形式，且根据for a whole class .，可知一节课一直在玩，所以用过去完成进行时态，表示过去一段时间内一直在进行的动作。选C。
