题目内容
1.Mr.Brown,our geography teacher,________________,for his bag with maps and a globe are already on the teacher's desk.( )A. | must arrive | B. | must have arrived | ||
C. | can have arrived | D. | has arrived |
分析 布朗先生是我们地理老师;他肯定已经到了,因为他的包、地图个地球仪已经在讲台上.
解答 答案是B.本题考查"情态动词+have done"的结构.对过去的或已经发生的事件的说明往往用"情态动词+have done"的结构,由句中的already 可知事件已经发生,所以用"情态动词+have done"的结构,排除A.must have done表示推测,表示"肯定已经…";can have done通常不用在肯定句中,排除C;根据语境,因为地理老师的包等已经在讲台上,由此推测,地理老师"肯定已经到了",故答案选择B.
点评 要在正确理解情态动词的基本含义的基础上,整体理解语境中的情感态度,做出合理的判断.
