是情态动词
hadn'tbetter
had+主语+better
Hadbetter意为“最好”,后接不带to的不定式.如:
—Wehadbettergonow.
—Yes,wehad(we'dbetter/wehadbetter).
Hadn'twebetterstopnow?(Hadwebetternotstopnow?)
IthinkI'dbetterbegoing.(用于进行时态,表“最好立即”)
Youhadbetterhavedonethat.(用于完成时态,表未完成动作)
注:①hadbest与hadbetter同意,但较少用.②Youhadbetter…用于同辈或小辈,对长辈不可用.
3.Wouldrather意为“宁愿”,表选择,后接不带to的不定式.如:
I'drathernotsayanything.
Wouldyouratherworkonafarm?
—Wouldn'tyouratherstayhere?
—No,Iwouldnot.I'drathergothere.
由于wouldrather表选择,因而后可接than.如:
Iwouldratherworkonafarmthaninafactory.
IwouldratherwatchTVthangotoseethefilm.
Iwouldratherloseadozencherrytreesthanthatyoushouldtellmeonelie.
I'dratheryoudidn'ttalkaboutthistoanyone.(句中的'drather不是情态动词,would在此是表愿望的实义动词)
