實戰(zhàn)演練
:
1.The English teacher ____ in this village for ten years.
A.have lived B.has lived
C.lives D.living
解析:由時間狀語for ten years可知,動作從過去持續(xù)到現(xiàn)在,有可能繼續(xù)下去,所以用現(xiàn)在完成時have/has done結(jié)構(gòu),因主語是第三人稱單數(shù),所以用has done,故選B。
2.He ____ the key in the office. Now we have to wait outside the room.
A.leave B.left
C.have left D.has left
解析:由下文Now we have to waitoutside the room可知,上文“落下鑰匙”的動作發(fā)生在過去,且對現(xiàn)在造成影響,所以用現(xiàn)在完成時have/has done結(jié)構(gòu),因主語是第三人稱單數(shù),所以用has done,故選D。
