        1. 【題目】Paul did a great job in the speech contest. He many times last week.

          A. need have practisedB. might practise

          C. must have practisedD. could practise

          【答案】C

          【解析】

          考查情態(tài)動詞。句意:保羅在演講比賽中表現(xiàn)得很好。他上星期一定練習了很多次。must have done是對過去發(fā)生的動作最有把握的猜測,意思是“一定”。故C選項正確。
