We shall/will be leaving. 第二人称 You will be leaving. You will be leaving. 第三人称 He/She/It will be leaving. They will be leaving. 3、 将来进行时的用法 将来进行时表示在将来某一时间内正在进行的动作。将来进行时有很强的推测性，因此人们往往在以下几种场合中使用它： 1. 表示将来某一时间正在进行的动作，一般带状语。 例如： 　　1) What will you be doing at this time next Monday? 　　 下周一的这个时候你将做什么了？ 　　2) When he comes to my house tomorrow, I will be writing the report. 　　 明天他来我家时，我将在写 报告 软件系统测试报告下载sgs报告如何下载关于路面塌陷情况报告535n,sgs报告怎么下载竣工报告下载 。 2. 表示现在正在进行的动作，但这个动作会延续到将来。 例如： 1) I wonder if it will still be raining this afternoon. 我想知道今天下午是否还会一直下雨。 2) I think that she will be working on this experiment until next morning. 我想她会一直在做这个实验直到第二天早上。 3. 表示预定的将来动作或对将来的预测。 例如： 1) Tomorrow I will be flying to Bombay. 明天我将飞往孟买。 2) After you take the medicine, you will be feeling much better. 吃完药后，你会感觉好很多。 4. 表示委婉的请求。 例如： 　　When shall we be meeting again？ 我们什么时候能再见面？ 5. 表示原因。 例如： Please come tomorrow afternoon .Tomorrow morning, I'll be having a meeting. 明天下午快点来。明天早上我将有一个会议。 6. 表示结果。 例如： 　　Stop the child or he will be falling over. 快阻止孩子，要不然他会摔跤的。 7. 表示对将来的打算（区别于对将来的预测） 例如： My duties will end in July, and I'll be returning to Beijing. 七月我将结束工作，返回北京。 过去将来时 1、 概念 过去将来时的动词表示对过去某一时间来说将要发生的动作或呈现的状态。这个时态常用在宾语从句中。 2、 过去将来时用法 1. should/would+动词原形 例如： 1) He said he would be there before Monday. 他说他星期一以前将在那里。 ( be 动词肯定式 ) 2) We hoped she should not go the next week. 我们希望下星期她不去。 ( do 动词的否定式 ) 注意：这个时态是一个相对的时态，立足于过去某时，从过去的观点看未来。在一定的语境中也可于其他从句或句子中。 例如： 1) It was a problem whether he would support us. 他是否会支持我们还是一个问 题 快递公司问题件快递公司问题件货款处理关于圆的周长面积重点题型关于解方程组的题及答案关于南海问题 。 2) It was seven o’clock. The sun would soon set. 这时是七点钟，太阳即将落山。 2. was/were going + 动词不定式 过去将来时的这种表达形式可以表示过去曾经打算或计划准备要做的事。 例如： 1) They told me that they were going to have a picnic. 他们告诉我他们将要举行一次野餐。 2) We were going to have a meeting. 我们曾经打算开个会。 过去将来时的这种形式可以表示过去将要发生或很有可能发生的事，但未实现的动作。 3) I was just going to ring him up when she came. 我刚要给他打电话，她就来了。 (电话没打成) 有时也用 was/were + coming 表示过去将来时。 例如： She didn't know when they were coming again. 她不知道他们时候会再来。 3. was/were about + 动词不定式 表示在过去看来正要做某事。 例如： 1) They were about to leave when the telephone rang. 他们正要走，电话铃响了。 2) I was just about to go to bed when she came to see me. 我正要睡觉，她来看我了。 4. was/were + 动词不定式 表示定于过去某时将要做某事。 例如： 　　He was to meet her at 10 on the street. 他约定和她10点钟在街上见面。 注意：若表示过去没有实现(或被取消)的计划，则用was (were) to+动词完成时。 例如： They were to have left at 7 last night. 他们本来计划昨晚7点离开的。 5. would（should）+动词原形 把助动词be变为过去式，把will，shall变为过去式。 例如： 1) I told them that I would not go with them，if it rained. 我告诉他们，如果下雨我就不和他们一起去了。 2) He didn’t know how to do it. What would be their ideas？ 他不知道该怎么办，他们会有什么想法呢？ 6. would（should）+动词原形 过去将来时常可用来表示过去习惯性的动作。此时，不管什么人称，一律用would。 例如： 1) Whenever she had time，she would do some reading. 她一有时间，总是看书。 2) I would play with them when I was a child. 当我还是孩童时，总是和他们一起玩。 现在把将来进行时与过去进行时用法归纳如下表： 将 来 进 行 时 构成 will /shall be＋现在分词 基本 用法 1）表示将来某一时间正在进行或持续的动作。 2）表示按计划或安排要发生的动作。 3）表示委婉语气，有时用将来进行时可使语气更委婉。 注意事项 1）为避免will给人误以为是表示“意愿”的情态动词，口语中表示单纯的将来时常用将来进行时。 2) 条件状语从句和时间状语从句中须用现在进行时代替将来进行时。 过 去 将 来 时 构成 would+动词原形/was (were) going to/was (were) about+不定式/was (were)+不定式 基本 用法 1）would do 表示从过去看某事将要发生。 2）用was (were) going to do表示过去某时计划或安排要做某事。 3）用was (were) about+不定式表示在过去看来正要做某事。 4) was (were)+不定式，表示过去计划安排将要发生的动作，语气较为正式。 注意事项 1）表示过去没有实现(或被取消)的计划，则用was (were) to+动词完成式。 2) 在条件和时间状语从句中，要表示过去将来须用一般过去时代替过去将来时。 3）come，go，leave，arrive，start等动词可用过去进行时代替过去将来时。 Module 2 unit 2 语法 1.
