人教版高中英语选修八 Unit5 Meeting your ancestors-语法篇（教师版）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 maths 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。
