四、考查现在完成时与其他时态的联系和区别。如:
1. sun's aunt has gone there for ten years.(改成正确的句子)
析:非延续性动词与"段时间"连用时,除了把非延续性动词改成延续性动词外,还可把动词改为一般过去时或借助句型"it's +段时间+since+从句"进行句子转换。故答案为:sun's aunt has been there for ten years. /sun's aunt went there ten years ago. /it's ten years since sun's aunt went there.
2. susan has been in this city for more than ten years.(改为同义句)
________more than ten years ____susan ______to this city.
析:据上题分析,且since引导的从句要用一般过去时,故填it is, since, came。
3. i won't go to the concert because i ____my ticket.
a. lost b. don't lose c. have lost d. is coming
析:因我丢了票的动作发生在过去,而且对现在造成了我不能参加音乐会的结果,符合现在完成时所表示的含意,故选c。
英语的行为动词有持续性动词和瞬间性动词之分,使用中应注意两者的区别。
一、持续性动词: 表示一个动作可以持续一段时间或更长时间。
常见的study, play, do, read, learn, drive, write, clean , sleep, speak, talk, wait, fly, stay, sit, stand, lie, keep等。
