Mad or not?
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.

☆or not:在疑問句的后面表示是還是不是，選擇概念
mad or not=mad or not mad

☆come into use:投入使用

☆Over a hundred people must have been driven away from their homes by the noise.
這句好好分析一下
home:家，強調有感情；house僅僅指房子

☆left:leave的過去分詞，表示被留下來的
left作定語放在被修飾詞的后面：剩下的

☆offer=give:提供
give sb sth/give sth to sb 雙賓語
雙賓語的被動語態(tài)，主語有兩種可能：以sb作主語或以sth作主語
give sb sth-->sb be given sth
give sth to sb-->sth be given to sb
用離動詞最近的賓語作主語
