二、While-class
1.构成：主语+ have/has been +动词的现在分词+其他成分
2.基本用法：
现在完成进行时表示动作从过去某一时刻开始，一直延续到现在或离现在不远的时间，其动作可能刚刚停止，也可能继续下去。该时态多用于延续性动词，如live，learn，lie，stay，sit，wait，stand，rest，study等，并常和all this time，this week，this month，all night，all the morning，recently 等状语以及由since和for构成的时间状语（从句）连用，与since和for连用时，常表示动作会继续下去。
I have been waiting for an hour and he still hasn't turned up.
我已经等了一个小时了，可他还没出现。（动作还在继续进行）
I've been writing letters all this morning.
我写了一上午信。（动作可能会继续下去，也可能刚停止）
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）
注意：
现在完成时与现在完成进行时的区别
①现在完成进行时表示的动作很可能持续下去，强调动作的延续性；而现在完成时通常表示动作已经完成，强调动作对现在的影响或产生的结果。
②有时现在完成进行时所表示的动作并不是一直在不停地进行，而是在断断续续地重复；而现在完成时一般不表示重复的动作。这时现在完成进行时可用于非延续性动词。
You have been saying for a year that you will study abroad.整整一年你都在说要出国留学。
③现在完成进行时往往带有某种感彩：而现在完成时通常说明事实，表述平铺直叙。
He's been working too hard.他工作太努力了。
