4、e past. 现在完成进行时用法 1.现在完成进行时的概念: 表示动作从过去某一时间开始一直持续到现在，这 个动作可能刚终止，也可能还在进行。 2. 现在完成时和现在完成进行时的区别: 1) 在不用时间状语的情况下，现在完成进行时的动作不一定已经完成，很可 能持续下去，而现在完成时一般表示动作已经完成。即现在完成进行时强调 动作的延续性，而现在完成时强调动作的结果。例如: a. Ive been designing solar racing cars. (我一直在设计太阳能赛车。) b.Ive designed five or six differert cars. (我已经设计五六辆小汽车

5、了。) 2) 现在完成进行时往往表示动作在重复，而现在完成时一般不表示动作的重 复。例如: a. Ive been taking part in races for four years. ( 我这四年一直在参加比赛。) b. How many races have you taken part in? (你参加多少场比赛了? ) 3)现在完成进行时与所有进行时态一样带有感情色彩，可使表达显得生动，而现在 完成时往往只表明一个事实、一种影响或结果，不带感情色彩。例如: What have you been doing? You look fed up.(你一直在干什么呀?你看上去很不高兴。)

6、3. 常与现在完成进行时连用的时间状语 现在完成进行时常与表示-段时间的状语连用，例如: all the time, this week, all night, these few days, for., since.等。 例如: a. A private detective has bee tailing him for several weeks. (一位私人侦探几个星期以 来直在跟踪他。) b. Craig loves outdoor aivties -he skis in winter and has been fising and hunting since he was a chi
