七、一般将来时 概念：表示将要发生的动作或存在的状态及打算、计划或准备做某事。 时间状语：tomorrow, next day(week, month, year…),soon, in a few minutes, by…,the day after tomorrow, etc. 基本结构：①am/is/are/going to + do；②will/shall + do. 七、一般将来时 A) 基本结构是will / shall do。例：We shall send her a glass hand-made craft as her birthday gift. B) 有些动词，如：arrive, close, come, do, go, have, leave, open, play, return, sleep, start, stay等，用于现在进行时，并且通常与一个表示将来时间的时间状语连用，可以表示将来时。例：My mother is coming to visit me next week and is staying here until May.  练习 1、There a meeting tomorrow afternoon.（明天下午将会有个会议） 2、If they come, we (have) a meeting. 3、He in three days.（他3天后会回来） 4、There (is) a birthday party next Sunday. 5、It (take) us a long time to learn English well. 八、过去将来时 概念：立足于过去某一时刻，从过去看将来，常用于宾语从句中。 时间状语：the next day(morning, year…),the following month(week…),etc. 基本结构：①was/were/going to + do；②would/should + do. 否定形式：①was/were/not + going to + do;②would/should + not + do. 一般疑问句：①was或were放于句首；②would/should提到句首。 八、过去将来时 判断这种时态的依据是:要有表示过去的“动作”,而不是时间。 例: I said on Thursday I should see my friend the next day.（我星期四说我将于第二天拜访我的朋友。） 例：I knew he was about to go to England. 例：She said she was leaving this evening. 练习 1、We didn’t know whether he (speak) at the meeting. 2、Jenny said she (spend) her holiday in China. 3、I heard that they (return) to Shanghai soon. 4、Lily rang up her mother that (buy) some books. 九、现在完成进行时 概念：现在完成进行时，是英语中，动词的一种基本时态，其构成为：主语+助动词（have）+动词的过去分词+其他成分。其表达的意思有两种：1.表示从过去某时开始一直持续到现在的动作，并且还将持续下去。2.表示在说话时刻之前到现在正在进行的动作。 九、现在完成进行时 主语+have（has）been+动词-ing （一）表示从过去某时开始一直持续到现在的动作，并且还将持续下去。 例：The Chinese have been making paper for two thousand years. 中国有2000年的造纸历史。（动作还将继续下去） 九、现在完成进行时 （二）表示在说话时刻之前到现在正在进行的动作。 We have been waiting for you for half an hour. 我们已经等你半个钟头了。（人还没到，如同在电话里说的，还会继续等）
