现在完成时考点归纳一、现在完成时的用法1.表示动作发生在过去,持续到现在,并有可能继续下去。
2.表示动作发生在过去,对现在造成影响。
结构:have/has done实战演练:1. The English teacher ____ in this village for ten years.A. have livedB. has livedC. livesD. living解析:由时间状语for ten years可知,动作从过去持续到现在,有可能继续下去,所以用现在完成时have/has done结构,因主语是第三人称单数,所以用has done,故选B。
2. He ____ the key in the office. Now we have to wait outside the room.A. leaveB. leftC. have leftD. has left解析:由下文Now we have to wait outside the room可知,上文“落下钥匙”的动作发生在过去,且对现在造成影响,所以用现在完成时have/has done结构,因主语是第三人称单数,所以用has done,故选D。
