1、第10讲Meeting your ancestors 语法篇_1.掌握现在完成进行时的用法;2.能够区分现在完成时与现在完成进行时。现在完成进行时(1)结构由“have/has been+动词的现在分词”构成,表示从过去某时开始,一直持续到现在的动作,可能刚刚停止,也可能还在继续进行。例如:We have been looking for you for an hour.我们找了你一个小时。(动作刚停止)She has been teaching English since she graduated.她毕业后一直在教英语。(动作还在继续进行)We have been going over m
2、aths these days.我们这些天一直在复习数学。(动作还在继续进行)(2)有时现在完成进行时不是指某动作一直在不停的进行,而是表示一直到说话时为止的一段时间内一再重复的动作,常常带有感情色彩。例如:She has been saying that 20 times. 这话她已经说了20遍了。He has been calling on her several times this week. 他这个星期几次来看他。We have been having a lot of rain recently. 最近雨水很多。(3)有时现在完成进行时表示刚才或近来发生的动作,也可表示知道说话时为
3、止的一段时间内发生的动作,这一动做到说话时已经结束,而且一般不再继续下去;这种用法主要表示某一动作所产生的结果或对现在的影响。例如He has been working too hard.他工作太辛苦了。The girl has been playing with toys.那个女孩一直在玩玩具。You have been cleaning the classroom, I think.我想你刚才在打扫教室吧。(4)现在完成时和现在完成进行时现在完成时和现在完成进行时均可表示从过去开始一直持续到现在的动作,有时两者可换用。这两种时态的主要区别有两个 :其一:现在完成时表示动作已完成,着重结果;
4、现在完成进行时表示动作的进行,强调动作的持续性。比较: I have watered the flowers.我已经给花浇过水了。(已完成:你不必浇了) I have been watering the flowers.我一直在给花浇水。(未完成:一直在浇)其二:状态动词、知觉动词或情感动词如:see, feel,know,love 等,不可用于现在完成进行时,但可用于现在完成时,例如:I have known her for a long time.我认识她已经很久了。I havent seen him theses days.这些日子我没有见过他。1.
