浅析现在完成
与现在完成进行
Lead-in
现在完成时分为两个主要用法：① “已完成”用法---指动作或过程发生在说话之前某个没有明确说出的过去时间，并与现在有联系；② “未完成” 用法---指动作或状态从过去某时开始持续到现在，可能继续下去，也可能刚刚结束。
Lead-in
现在完成进行时 指动作或状态从过去某时开始一直持续到现在，还可能继续下去（也可能讲话时刻前刚结束）。

如何得知一个句子中的动词用于现在完成时态时
是 “已完成” 用法，还是 “未完成” 用法？
Discussion
To find out the answer by analyzing the
following sentences.
1. I have lost my key.
2. Up to now, the work has been easy.
3. He has worn glasses since his childhood.
4. She has found a new job.
已完成
已完成
1. I have lost my key.
4. She has found a new job.
2. Up to now, the work has been easy.
3. He has worn glasses since his childhood
非延续性动词在现在完成时态中，通常不与
延续时间连用，表示“已完成” ；延续性动词
在现在完成时态中，则通常与延续时间连用，
为 “未完成” 用法。
Conclusion
延续性动词在现在完成时态中，可否不与延
续时间连用，构成 “未完成” 用法？
﹖
Question
Please translate the following sentences.
1. Tom has been ill.
汤姆病好了。
2. Tom has been ill since last week.
汤姆自上周以来一直病着。
延续性动词不一定就表示 “未完成” 用法。
Summary 1
现在完成时态中，延续性动词+延续时间，表动作延续到了现在，还可能继续下去，为“未完成”用法；延续性动词不加延续时间表示动作在讲话时刻之前就结束了，属“已完成”用法。
Practice
---Why, Jack, you look tired!
--- Well, I _____ the house and I must finish the work tomorrow.
A. was painting B. have been painting
C. will be painting D. have painted
解疑：
由后面 “我明天必须完工”可知，“paint”
的动作还没完成，需要延续到现在甚至将来。
而现在完成进行时表示动作的延续，现在完成
时通常加上时间状语后可表动作的延续, 所以
此处应选择B。

Question
3
I have drunk five cups of coffee this morning.
今天上午我喝了五杯咖啡。
I have been drinking five cups of coffee this morning
I have drunk five cups of coffee this morning.
重复性
I ___ the dishes for over a week. It’s your turn.
---I knew you would say something like that.
had washed B. have been washing
C. washed D. wash
疑问：
现在完成时态与现在完成进行时态都能表
示重复，为什么这个语境中，只能使用现在完
成时态，而不能使用现在完成进行时态？
Discussion
Larry King has been interviewing important
people for more than 40 years. King has been
asking famous people questions throughout his career and has done more than 40,000 interviews. He has talked with every American president since Richard Nixon.
Analysis
has been interviewing 和has been asking 都是表示重复的动作，但由于并没有说明具体的次数，所以用了完成进行时态，来强调他到目前为止还一直在从事参访活动。而接下来由于说出了具体的40,000次采访以及采访过每一位美国总统，这就使得动作被分割开来，所以改用了现在完成时has done 和has talked 来表达。
解疑：
现在完成时中的重复性是“显性”的，是明
确的，可以标明从过去到现在的具体几次或几
件事；现在完成行时的重复是“隐性的”，模糊
的。常常被看是一个从过去持续到现在的不间
断的重复活动。
Practice
It is the second time that Tom _________ the scholarship, which makes his parents proud a lot.
A. won B. has won
C. wins D. has been winning
解析：
现在完成时态表示具体几次的重复活动。
