情态动词的基本用法情态动词本身虽有一定的意义，但它必须和实义动词一起构成谓语动词，表示说话人的语气和情态，情态动词后接动词原形。初中学过的情态动词有can, could, may, must, need, shall, should, will, would, have to等。1. can / could表示能力（等于be able to）或客观可能性；还可以表示请求或允许；用在否定句、疑问句或感叹句中还可以表示惊异、怀疑、不相信的态度。can / could i .? 表示请求对方许可（用could比用can语气更加委婉和客气，但答语必须用can）；can / could you .? 用来表示说话人征求对方意见（用could比用can语气更加委婉和客气）。2. may表示许可或允许，意为“可以”。may i .? 表示征求对方许可，否定回答一般用mustnt或cant。3. must意为“必须、应当”，表示义务、命令或必要；在回答must引出的问句时，肯定回答用must，否定回答用neednt 或dont have to，表示“没有必要”。4. need作情态动词时，多用于否定句或疑问句中，表示“需要”或“必要”（need用于肯定句时，常作实义动词，有人称和数的变化）。5. shall表示说话人征求对方的意见或向对方请示。6. should意为“应该”，表示义务、责任，可用于各种句式。7. will用于疑问句中，表示说话人向对方提出请求或建议；还可以用来表示做某事的意志、意愿、决心或打算。8. would表示过去的习惯性动作，有“总是、常常”的意思；还可表意愿、拒绝、请求等。9. have to意为“不得不”，强调客观需要，能用于多种时态；而must强调说话者的主观看法，没有时态变化。【专项练习】. 请从各题后所给的a、b、c、d四个选项中选出最佳答案。( )1. must we clean the classroom now?
