进行时，是英语中，动词的一种基本时态，其构成为：主语+shall/will+助动词have+been+动词的现在行时的结构 　　主语+ shall/will + have + been + 现在分词 + 其他成分 　　如: 　　1.I shall have been working here in this factory for twenty years by the end of the year. [cn]到今 年年底，我将在这个工厂工作20年了[/cn] 　　2.The play is coming off in August. By then the play will have been running for three months. [cn]这个剧将于8月停演。到那时为止，这个剧将连演三个月了。[/cn] 　　3.By Friday midday, they will have been working on it for seven days.[cn]到星期五中午，他们就在这个工程上干了7天了。[/cn]   二、将来完成进行时的用法 　　在下列句子中，will是情态助动词，有“大概”或“我想”的含义。 　　如： 　　1.You’ll have been

行时由“had been +现在分词”构成。它的用法是表示从过去某一时间开始一直延续到另外一个过去时间的动作，这个动作在当时仍在进行并可能继续延续下去。例如： 1. We had been studying what our enemy had said，but we were not able to understand it. 我们一直再研究我们的敌人说的话，但是，我们还是不能理解它。  had been suffering from a bad cold when she took the exam.  当她参加考试的时候，她正生病着呢。 3.He had been mentioning your name to me. 他一直向我提起你的名字。 4.He was very tired. He had been working all day. 他很累。他干了一整天活。 5.I had been watching TV at home last night. 昨晚我一直在看电视。 6.My parents had been watching TV at 8:00 last night. 昨晚八点钟时我的父母亲都在看电视。 二、过去将来进行时发生的时间和将来进行时差别很大，过去将来进行时是指一个过去正在发生的动作，特变强调“过去发生”。而过去完成进进行时由“had been +现在分词”构成。它的用法是表示从过去某一时行时是指过去将来某个时刻已经完成的动作，强调的是“已经完成”。比如： 1.He told me that she would be shopping the next day this time. 他对我说第二天的这个时候他正在购物呢。 2.He said that the minister would be giving a speech on international affairs the next day this time. 他说第二天的这个时候部长将就国际事务发表演讲。 3.The new name he would be using was Jack Jones. 他将用的新名是杰克•琼斯。 4.The new book he would be getting was“FORREST GUMP”. 他将得到的新书是阿甘正传。

year. A. studies B. studied C. is studying D. has been studying 分析：D。根据句中的现在进行时可排除B，再根据句中的for a year可知此题选现在完成进行时最佳，即选D。 5. —I have got a headache. —No wonder. You ______ in front of that computer too long. A. work B. are working C. have been working D. worked 分析：C。由于在电脑前工作太久，所以导致了现在头痛的结果，故空格处应填现在

现在时、现在进行时在读英语。 Listen! He is answering the phone. 听，他正在接电话。 现在进行时的否定形式： 只要再be动词(am,is,are)后面加not就行了。 He is working now. → He is not working now. She is reading English. → She is not reading English. 现在进行时的一般疑问句： 就是把be动词(am,is,are)提到主语之前就可以了。 Is he working now? 他现在正在工作吗? Is she reading English? 她正在读英语吗? 现在进行时的特殊疑问句： 疑问词+be动词

行时是我们经常遇到的一种时态，它是表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作，例如： 1.He fell asleep when he was reading. 他在读书时睡着了。 2.We were expecting you yesterday. 我们昨天一直盼着你来。 3.He was playing while I was studying. 我学习的时候他在玩。 4.I was wondering if you could give me a lift. 我那时正在想着你能不能载我一程。 5.We were hoping you would stay with us. 我们希望你能和我们在一起。 6.I was having a talk with my teacher at that time. 那时，我正在跟我的老师谈话。 三、英语词汇通过变形来表示各种时态，过去进行时的基本结构

行时主要表示过去某时的一个动作正在进行。例如： 1. I was writing a letter when she came to see me. 当她来看我时我正在写信。 2.I had been writing a letter for two hours by the time she came to see me. 当她来看我的时候，我已经写了两个小时的信了。 5. 过去完成进进行时是一种比较抽象的时态，学习它需要理解整个句子所处的语境和时间。过去完成进行时行时与过去完成时的不同。过去完成时表示过去某时间前已经发生的动作或情况，这个过去的时间可以用by，before等介词短语或一个时间状语从句来表示；或者表示一个动作在另一个过去动作之前已经完成。例如： 1. They had just had breakfast when Tom came in. 汤姆来时，他们刚吃过早饭。 2. They had been having breakfast for ten minutes when Tom came in. 汤姆来时，他们已经吃了十分钟的早饭了。

行时。例如： 1. While he was waiting for the bus，he was reading a newspaper. 他边等车边进行时看报。（两个动作都是延续的） 2.He was cleaning his car while I was cooking. 他擦车时我在做饭。（两个动作同时进行） 3.They were singing while we were dancing. 我们跳舞的时候他们正在唱歌。 4.When I was doing my homework,my mother was cooking. 当我正在做功课的时候，我妈妈正在做饭。 5.When my mother was doing the housework,my father was watching TV. 当我妈妈正在做家务的时候，我爸爸正在看电视。

行时，表示动作的重复。如：   [en]His heart is beating fast.[/en] [cn]他的心脏跳得很快。[/cn] 4.某些表示希望或想法的动词(如hope, wonder, want等)的进行时可以表示委婉客气。如： [en]I’m wondering whether you can help us now.[/en] [cn]我不知道你现在能否帮我们一下。[/cn] [en]I’m hoping that you will succeed.[/en] [cn]希现在进行时与一般现在时的区别 一、概念不同： 一般现在时望你能成功。[/cn]
