1.預習導學：
a. 假如你有一百萬,你會做什么?________________________________________
A: 這是虛擬語氣,語氣是動詞的一種形式,表示說話人對說話內容的看法和態(tài)度
英語的語氣有三種: 陳述語氣,祈使語氣和虛擬語氣. 虛擬語氣表示說話人
認為所說的話是和事實相反的內容,只是一種愿望.假設.猜測或空想,本單元
是虛擬語氣在非真實條件句中的運用,表示說話人所陳述的內容是與事實相反或難以實現的假設。
其結構是：條件句--- if + 主語 + 動詞的過去式(be用were)
主句------主語+ would + 動詞原形

“several +mollion(s)+of …” 形式 , eg: several million(s) of cars
