十.情態(tài)動詞
can(能,會),may(可以,可能,也許),must(必須,一定,應(yīng)該)haveto(必須,不得不)
1.肯定句結(jié)構(gòu):主語+can/may/must+動詞原形+其它,例如:
I must go now.
2.否定句結(jié)構(gòu):在can/may/must后加not,例如:
You mustn’t talk a loud in the library.
3.一般疑問句結(jié)構(gòu):把can/may/must提在主語前,例如:
Must you go now?(Yes,Imust.No,Ineedn’t.)
May I open the window?(Yes,you may.No,you needn’t.)
十一.had better用法
had better+動詞原形表示“最好做……”,變否定句時在had better后加not。例如:
You had better catch a bus.
You’d better not catch a bus.(Youhad=You’d)
十二.特殊疑問句的變換
對劃線部分提問時,將劃線部分去掉,剩下部分變一般疑問句語序。(對主語提問例外)例如:
My name is Lily. What’s your name?
The river is 500 kilometres.Hong long is the river?。
