She couldnt skate when she was five years old. （能力） At that time we thought the story could be true （可能性） could用来提问, 是有礼貌的请求 Could.，please? 语气较为婉转。,23,e. g. Could I speak to Mr. Smith, please? 二. might和may的区别和用法: 1. may的用法: a. 表示“允许”或“请求”。 e. g. May I come in？,24,在使用这一用法时需注意: may表示“允许”的否定形式是must not, 意思是“不应该” “不许可”。e. g. May I take this book out of the reading-room？ No, you mustnt b. 表示说话人的猜测，认为某一事情“或许”或“可能”发生。,25,e. g. He may know the answer c. may用在感叹句中可表示祝愿、愿望。 e. g. May you succeed(祝你成功。) May you have a pleasant journey (一路平安。),26,2. might的用法: a. might可以代替may, 表示现在时间的动作，但语气较为婉转客气或更加不肯定。 e. g. Might I take a suggestion？ b. might用来表示现在时间时, 还可表示“规劝”。,27,e. g. You might pay more attention to spoken English 三. must与have to的区别 have to比较强调客观需要, must着重说明主观看法。另外have to能用于更多时态, 比较下面的句子：,28,We had to be there at 10:00. 有时两者都可以用, 意思差别不大。 e. g. We must/have to leave now. must在表示说话人对事物的推测时候要注意它比may肯定得多, 相当于汉语的“一定”或“准是”。(只有在肯定句中能这样用。),29,This must be your room 在回答由must引起的问题时, 如果是否定的答复，不能用mustnt, 而需要用neednt或dont have to, 因为mustnt是“一定不要”的意思。,30,表示对某件事的确定程度，即表示推测 的时候，通常会用到情态动词must, may, might, could等。 按照推测的可能性来区别, must的可 能性最大, may次之。could和might不表 示过去时态, 只是表示推测的可能性比 较小。例如： Its two oclock now. He must be in by now. 现在是两点钟。 他一定到了。,各种“预测“,31,He may go back in the fall. 他可能秋季回去。 He thinks it could / might be wise to try his luck there. 他想在那儿碰碰运气可能是明智的。 2. 情态动词表示推测的几种形式： 1）“情态动词+动词原形”表示对现在情况的推测。例如：,32,This book must be Toms. He is looking for it. 这本书一定是汤姆的。他正在找这 本书。 2）“情态动词+be +v- ing形式”表示对现 在正在进行的情况进行推测。例如： At this moment, our teacher may be correcting our exam papers. 此刻，我们老师可能正在批改试卷。,33,3）“情态动词+have+动词的过去分词”表 示对过去情况的推测。 例如： The road is wet. It must have rained last night. 路是湿的，昨天晚上一定下雨了。,34,【特别提醒】 must表示推测时只用于肯定句，表示 很有把握的推测，意为“一定”。例如： Our teacher must be in the office because the light is on. 我们的老师一定在办公室，因为灯还亮 着。,35,2. 表示否定推测常用cant，意为“不可 能”。 例如：He cant be at home because he has gone to Beijing. 他不可能在家，因为他去了北京。,36,1.
