1、練習(xí)材料：Lesson21???? Mad or not?（49s）

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.

情態(tài)動(dòng)詞must+完成時(shí)態(tài)，是對(duì)過(guò)去事情的推測(cè)，猜測(cè)某一事情肯定已經(jīng)發(fā)生。drive away， 趕走，逼走

練習(xí)/h/的發(fā)音：

/h/是字母h的發(fā)音。聲門摩擦輔音。發(fā)音時(shí)氣流送出口腔，在通過(guò)聲門時(shí)發(fā)出輕微摩擦；口形隨其后的元音而變化。/h/是清輔音，聲帶不振動(dòng)。
