I'll be having my classes then. 明天8点到10点之间请不要给我打电话，我那时正在上课。 将来进行时 2. 基本结构：will/shall be doing (1)肯定句：主语＋will/shall be＋doing＋... 例句：The minister will be giving a speech on international affairs in July. 部长将在七月份就国际事务发表演讲。 (2)否定句：主语＋will/shall not be＋doing＋... 例句：They won’t be playing football on Sunday morning. 周日早上他们不踢足球。 将来进行时 (3)一般疑问句：Shall/Will + 主语 + be + 现在分词 + 其他？ 例句：Will you be using your bicycle this evening? 今晚你用自行车吗？ (4)特殊疑问句：疑问代词/疑问副词 + shall/will + 主语 + be + 现在分词 + 其他？ 例句：When shall I be expecting you this evening? 今天晚上我几点等你？ 将来进行时 3. 用法 (1)表示将来某时正在进行的动作，它一般不表意愿，常表已安排好的事，给人一种期待之感，多与表示将来的时间状语连用。 例句：We will be seeing a fashion show this time tomorrow. 明天这个时候我们将在看一场时装表演。 I’ll be taking my holidays soon.不久我将要度假了。 Will you be telephoning him tomorrow? 你明天会不会给他打电话？ 将来进行时 3. 用法 (2)表示“纯粹”的将来，将来进行时不带感情色彩，而一般将来时中的will起着情态动词的作用，常表示意愿、决心等，因此，现代口语中常用此时态表示将来发生的动作或情况。 例句：I will go to Shanghai tomorrow. 我明天要去上海。（表意愿、打算、决心等） I will be going to Shanghai tomorrow. 我明天要去上海了。（单纯表将来时间） 将来进行时 3. 用法 (3)表示推测，will还有“大概”或“一定”的意味，即表示一种揣测和表示某种倾向或习惯性的动作，常与now连用。 例句：They will be watching football game now. 他们现在大概在观看足球赛呢。 It’s Sunday. She won’t be studying now. 今天是星期天，她不会在学习的。 将来进行时 3. 用法 (4)表示婉转口气，表达有礼貌的询问、请求等。 例句：Will you be needing anything else？你还需要什么吗？ When will you be coming to see me? 你什么时候会来看我？ Will you be lending me your bike? 你能借给我你的自行车吗？ 注意：在时间、条件等状语从句中，用现在进行时代替将来进行时。 例句：Be careful when you are crossing the street. 过马路时要当心。 将来进行时 1.将来进行时表示将来某时正在进行的动作，而一般将来时表示将来某时将要发生的动作。 例句：What will you be doing at seven the day after tomorrow？ 后天晚上七点你会在做什么呢？ What will you do at seven the day after tomorrow? 后天晚上七点你做什么？ 与一般将来时的区别 2.将来进行时表示已有的安排，而一般将来时表示临时决定。 例句：I’ll be going to see him after school. 放学后我准备去看他的。 I’ll go to see him after school.放学后我去看他。 3.两者均可表示将来，但用将来进行时语气更委婉。比较： 例句：When will you be finishing your homework? 你什么时候完成家庭作业呢？ When will you finish your homework? 你什么时候完成家庭作业？ 与一般将来时的区别 4.有时将来进行时只是单纯地谈未来情况，而一般将来时中的will含有“愿意”的意思。比较： 例句：Mary won’t be paying this bill. 不是玛丽来付钱。（单纯谈未来情况） Mary won’t pay this bill. 玛丽不肯付这笔钱。（表意愿） 与一般将来时的区别 现在进行时表示一种正常状况下正在进行的动作 而将来进行时表示在将来预测要进行的动作。因此将来进行时不如现在进行时那样肯定，比后者偶然性要大一些： 例句：I am seeing Tom tomorrow.明天我要和汤姆见面。 I'll be seeing Tom tomorrow.明天我会见到汤姆。 注意：第一句意指汤姆或说话人已经特意安排了这次会面，而第二句则意指汤姆和说话人将在通常进程中见面（也许他们在一起工作）。 现在进行时用于表示最近将来的动作时，必须有确定的时间；将来进行时可以和确定的时间状语连用，也可以不连用。它既可以表示最近将来的动作，也可以表示较远将来的动作。 与一般将来时的区别 Vocabulary decrease vi.& vt.减少；（使）变小或变少 n.减少 decrease to减少到…… decrease by减少了…… on the decrease在减少 例句：The production of wheat decreased by 15% as a result of the dry weather. 由于天气干燥，小麦的产量下降了15%。 练习：By the end of last year, the number of people buying Japanese cars had decreased 20%. by deny vt.否定，否认；拒绝接受 deny doing sth. ＝deny having done sth. 否认做过某事 There is no denying that...不可否认…… 例句：No one can deny the fact that enough sleep at night is beneficial to our health. 没有人能否认晚上充足的睡眠对 我们的健康有益这一事实。 练习：The babysitter denied (abuse) the young child. Apparently, she was lying. abusing/having abused quantity n.大量；数量 a quantity of/quantities of大量的 in quantity在数量上；大量地 in large quantities大量，大批 例句：As a result of destroying the forests, a large quantity of desert has covered the land. 由于破坏了森林，大量的沙漠覆盖了这片土地。 练习：The food in the hotel was enough quantity, but not very good in quality.‌ in Exercise 单词拼写 1.
