Lesson 21 Mad or not?
　　课文内容：
　　Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built years ago, but for some reason it could not be used then. Last year, however, it came into use. Over a hundred people must have been driven away from their homes by the noise. I am one of the few people left. Sometimes I think this house will be knocked down by a passing plane. I have been offered a large sum of money to go away, but I am determined to stay here. Everybody says I must be mad and they are probably right.
　　语法归纳：将来进行时和各种完成进行时的被动语态
　　英语中一般没有将来进行时和完成进行时的被动语态，如果要使用这些被动语态则要对其他时态作必要的改动„
　　将来进行时的被动讲态——改为将来时的被动语态;完成逬行时的被动语态——改为完成时的被动语态，比如：
　　1)我们讨论这个问题已经两天了。
　　主动语态：We have been discussing this problem for two days.(现在完成进行时)
　　被动语态：This problem has been discussed for two days.(现在完成时的被动语态)
　　2)这个问题我们明年再协商。
　　主动语态：We shall be discussing this problem next year.(将来进行时)
　　被动语态;Tlis problem will be discussed next year.(一般将来时的被动语态)
　　逐句精讲：
　　1.Aeroplanes are slowly driving me mad.
　　飞机正在逐渐把我逼疯。
　　语言点1 drive sb. mad使某人发疯

　　2.I live near an airport and passing planes can be heard night and day.
　　我住在一个机场附近，过往飞机日夜不绝于耳。
　　语言点1 near意为“在附近”，所指距离可近可远，此词作介词时意思较为含糊。
　　语言点2 be heard意为“被听到”，被动语态，强调作者不得不听的意思。
　　谲言点3 passingplanes意为“经过的飞机”，现在分词在此相当于形容词，作定语。相同用法举例：a crying baby 一个正在哭的宝宝 a dancing boy 一个正在跳舞的男孩 a standing teacher 一位站着的老师
　　语言点4 night and day意为“夜以继日”，词义关键体现在and―词上
　　3.The airport was built years ago, but for some reason it could not be used then.
　　这个机场是许多年前建的，但由于某种原因当时没能启用。
　　语言点1 was与过去时间状语years ago时态一致，实际在years ago前省去了many。
　　语言点2 for some reason因为某种原因(代表某种不确定或不想说明的原因)
　　For some reason，the television doesn’t work. 因为某种原因，电视机坏了。(我们不是修理电视机的专家，只知道坏了，不知道具体原因。)

　　He thinks，with reason, that I do not want to leave.他有理由认为我不想离开。

　　语言点 “动词+ into”短语：come into use投入使用; change into变成;get into卷入，进入：get into troubles 惹上麻烦;throw into 拓进;creep into 爬进;sb. be into 给……迷住，对…… 深感兴趣：My brother, Jay, is into computer game now. 我弟弟杰伊现在对电脑游戏着迷。
　　5.Over a hundred people must have been driven away from their homes by the noise.
　　有100多人肯定是被噪音逼得已经弃家远去。
　　语言点1 have been driven away... by...，此句为典型的现在完成时的被动语态。
　　语言点2 over—词多义，基本意思是“在……之上”, 这里意为“超过”。 其他用法：Try it over.再试试看。/ be over-careful过分谨慎; over the street在街对面
　　语言点3 drive的常用短语：drive away赶走;drive out赶出;drive into赶进;drive sb. back把某人赶回;drive sb. mad把某人逼疯;drive at用意所在;drive to开车前往

　　6.I am one of the few people left.

　　语言点1 “one of +范围，，表示“……中的一个”：He is one of the gangsters. 他是歹徒之一。
　　语言点2 the few people其中为数不多的人

　　有时候我觉得我的房子会被一架飞过的飞机撞倒，
　　语言点1 此句的核心语法点是将来时的被动语态，结构为：will be done (+by...)

　　语言点 (1) offer作动词意为“提供;给予;贡献;愿意;出价”：
　　offer a few ideas提出几点意见;offer to help sb.表示愿意帮助某人
　　(2) offer作名词指在求职、留学申请等情况的录取通知
　　He is expecting tiie ofifer of Harvard University day and night 他日夜都在期待着哈佛大学的录取通知书。
　　9.Everybody says I must be mad and they are probably right.
　　大家都说我肯定是疯了，也许他们说的是对的。
　　语言点1 再次强调，everybody作主语时必须视为单数形式，对应的谓语动词用单数。
　　语言点2 probably (adv.很可能地)修饰right (adj.对的)，相当于must be right。
