   【句型一】Be + 主语 + …?


  Are these books on the desk? 这些书在桌子上吗?
  Is your mother at home? 你妈妈在家吗?
  Was he here a moment ago? 他刚才在这儿吗?
  【用法说明】在含有连系动词be的将来时(shall 1 / will + be) 或完成时态(have / has + been) 的句子,改为一般疑问句时,只需将shall / will 或have / has提到句首。如:
  Will they be at home tonight? 他们今晚在家吗?
  Has he been to New York? 他去过纽约吗?
  【句型二】Do / Does / Did + 主语 + 谓语 +…?
  Do you like English? 你喜欢英语吗?
  Did he pass the exam? 他通过了这次考试吗?
  Does she have a computer? 她有一台电脑吗?
  【用法说明】助动词 do 要随人称和时态而变化。在一般现在时中,除第三人称单数用 does 外,其他人称用 do。而在一般过去时中,任何人称都用 did。同时,还应注意把原陈述句的行为动词改为动词原形。
  【句型三】情态动词 + 主语 + 谓语 +…?
  Must I finish my homework now? 我必须现在完成我的家庭作业吗?
  Dare 2 you swim in the lake? 你敢在这个湖里游泳吗?
  May I come in? 我可以进来吗?
  【用法说明】有的情态动词(如 need, dare) 既可作情态动词,也可作行为动词,因此它们的一般疑问句有两种形式。如:
  Need you go so soon? 你非得这么快就走吗?(情态动词)
  Do you need to go so soon? 你非得这么快就走吗?(行为动词)
  【句型四】Have / Has + 主语 + 过去分词 +…?
  Have you heard from him? 你收到他的来信吗?
  Has he finished his homework? 他完成了家庭作业吗?
  【用法说明】本句型是现在完成时的一般疑问句句型。have / has 在此作助动词,没有实际意义。另外,在美国英语中,无论 have 表示“有”或用作行为动词,其一般疑问句都要借助于助动词 do 的适当形式。而在英国英语中,只有当 have 作行为动词时,其一般疑问句才要作助动词 do 的适当形式。如:
  Has she got a computer? 她有一台电脑吗?(英国英语)
  Does she have a computer? 她有一台电脑吗?(美国英语)
  Did you have a pleasant time? 你过得快乐吗?

v.aux.(主要用于第一人称)将
  • I shall always love you.我将永远爱你。
  • Which club shall we join?我们要参加哪个社团?
n.敢,挑战;aux.敢;vi.敢;vt.敢于,勇于面对
  • He didn't dare to look at her in the face.他不敢正眼看她。
  • How dare you?Take your hand off me at once.放肆!马上把你的手挪开。
