thebooksandanswerthequestions.(read)yourselfyourselfyourselvesPickPickingReadingReadshould&hadbetter當我們給他人提建議時，可以用hadbetter和should，表示“最好”或“應該”做某事，hadbetter的語氣比should強一些。Youwatchisbroken.Youhadbetterbuyanewone.你的手表壞了,你最好買個新的。YoushouldknowalittleaboutDIY.你應該對DIY有點了解。hadbetter(常簡略為’dbetter)，是一固定詞組，后面必須跟動詞原形，沒有人稱和數(shù)的變化。構成：hadbetterdosth.句型。湯姆，你最好今天去那兒。Tom,you’dbettergotheretoday.hadbetter的否定式是hadbetternotdosth.你最好不要錯過末班公共汽車。

Youhadbetternotmissthelastbus.should后面也要跟動詞原形，且沒有人稱和數(shù)的變化。你應該戒煙。

Youshouldstopsmoking.should的否定式是shouldnot/shouldn’t。你不應該喝酒后開車。Youshouldn’tdriveafterdrinking.1.當我們向他人發(fā)出命令、提出要求或建議時，常使用祈使句。其主語通常不明確表示出來。其否定形式是在動詞原形前加donot/don’t。為了表示客氣和禮貌，可以加上please。2.當我們給他人提建議時，可以用hadbetter和should，表示“最好”或“應該”做某事。否定形式是hadbetternot和
