課本中不會(huì)教你的[H]339　have to和have got to

339　have to和have got to

◎ 兩者都表示“必須，不得不”，to后要加動(dòng)詞原形。have to的否定式為haven't to或don't have to，疑問(wèn)式為Have you…？或Do you have to…？并可以與shall，will或情態(tài)動(dòng)詞連用，如will have to等。have got to的否定式只有一種形式haven't got to，疑問(wèn)式也只有一種形式：Have you got to…？并且不可同助動(dòng)詞或情態(tài)動(dòng)詞連用。
