　　ⅲ．语法
　　现在完成进行时
　　ⅳ.【重难点分析】
　　1. 现在完成进行时
　　构成：
　　肯定句：主语 + have / has been + doing
　　否定句：主语+have/has+not+been+doing
　　一般疑问句：have/has+主语+been+doing?
　　现在完成进行时表达“某一动作从过去开始一直持续到现在，有可能还要持续下去”，现在完成进行时的句子中多用延续性动词，如：live，learn，study，work等。
　　(1) i have been learning english for ten years. 我学英语已经十年了。
　　(2) she has been skating for four hours. 到现在为止她滑冰已经有四个小时了。
　　(3) i have been collecting stamps since i was ten years old. 我从十岁起就一直在集邮。
　　在这几个句子中，have和has是助动词，疑问形式需把助动词提前，否定形式在have或has后面加not，have not和has not可以分别缩写成haven’t和hasn’t，如：
　　(1) have you been doing your homework since this morning? 从今天早晨起你就一直在写作业吧？
　　(2) has he been writing the letters to his friend? 他是一直在给他的朋友写信吗？
　　(3) i haven’t been seeing films for a long time. 我有很长时间没有看电影了。
　　　 （表明没有看电影这个动作从过去一直持续到现在，还要继续持续下去。）
　　现在完成进行时与现在完成时的区别：
　　(1) 现在完成时强调动作的完成，而现在完成进行时侧重的是动作的持续进行。
　　如：
　　i have read a book about birds. （已经读完）
　　i have been reading a book about birds. （一直都在读，现在还在读，有可能会继续读下去）
　　(2) 两种时态都有延续性， 但现在完成时往往只说明一个事实，一种影响或结果，无感情色彩；现在完成进行时表示一个动作的延续、重复，有时有一定的感情色彩。
　　如：
　　she has been singing all the day. 她都唱了一整天了。（抱怨、厌烦）
　　2. since， from和for共5页，当前第1页12345

　　(1) from是介词，后接名词、动名词，表示事情的开始点，以from短语作状语时，句中的谓语动词可用一般现在、过去和将来时, 如：
　　the movie is on from 8:00 p.m. to 10:00 p.m. 这个电影在晚上8点到10点上映。
　　they chatted at the meeting from beginning to end．他们在会议上自始至终都在聊天。
　　(2) since则为介词或从属连接词，其后接名词、动名词或从句，表示从某一特定时间起直至现在或过去某一特定时间为止，依然继续着的事情的开始点，在以此为时间状语的句子中，谓语动词常用完成时。
　　如：
　　many things have happened since they came here．
　　自他们来这儿以后，发生了许多事情。
　　the teacher said that john had made great progress since last semester．
　　老师说从上个学期以来约翰取得了很大的进步。
　　(3) for 是介词，后接名词，可以用来计算持续的时间，表示事情从开始到结束所持续的时间，谓语动词常用过去时或完成时，for与一般现在时连用，表示时间一直持续到将来。
　　如：
　　the meeting lasted for hours. 会议持续了几个小时。
　　i studied the piano for three years. 我学过三年钢琴。
　　i've known her for five years. 我认识她已经五年了。
　　how long are you here for?　 你在这里要待到什么时候?

　　本题考察的是日常交际用语的运用能力。要求给每个句子配位。在理解各句的句意后，运用日常交际用语在不同场合的应答，就能逐一完成。如本题第一句的“hello， who’s that， please?”根据ii栏中e项的答语“this is mary speaking”可以推断出这里电话用语（请问您是哪位）。再如第四句“would you like to come to supper?”（你来吃晚饭好吗？）按照英美人士交际习惯，应该先说表示乐意，并致谢，就不难找到ii栏中的a项应答。
