focus,在英语中，表示对某件事物的确定程度即表示推测的时候，我们通常会用到以下情态动词:must,might,could,may,cant,couldnt.确信程度大小：must may might肯定和否定的推测：must（肯定），cant，couldnt(否定）,情态动词must,might,could,cant 后接动词原形,可以表示对现在的情况的推测.,It must be Tonys（是的）,belong to Tony.(属于),一.can和could的区别和用法1.can表示体力和脑力方面的能力,或根据客观条件能做某种动作的“能力”。e.g.Can you speak English？Can you make a cake？can用在否定句和疑问句中时有时表示说话人的“猜测”或“不肯定”。e.g.Can the news be true？(在日常会话中,can可代替may表示“允许”,may比较正式),2.could 是 can的过去式,表示过去有过的能力和可能性,还有怀疑和不肯定的意思(在否定和疑问句中)。e.g.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。e.g.Could I speak to Mr.Smith,please?,二.may和might的区别和用法:1.may的用法:表示“允许”或“请求”。e.g.May I come in？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表示说话人的猜测，认为某一事情“或许”或“可能”发生。e.g.He may know the answer may用在感叹句中可表示祝愿或愿望。e.g.May you succeed(祝你成功。)May you have a pleasant journey(一路平安。),2.might的用法: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？might用来表示现在时间时,还可表示“规劝”。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：We had to be there at 10:00.We must 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。)e.g.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。,各种预测,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。e.g.Its two oclock now.He must be in by now.He may go back in the fall.He thinks it could/might be wise to try his luck there.,2.情态动词表示推测的几种形式：“情态动词+动词原形”表示对现在情况 的推测。例如：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。“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。“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。,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。2.表示否定推测常用cant，意为“不可能”。e.g.He cant be at home because he has gone to Beijing.他不可能在家，因为他去了北京。,小帖士,Homework,Suppose when you and your friend walk in the street.You see a man running from a supermarket and a woman is chasing behind him with heavy things.Make up a conversation with your partner.,A:Oh,look!Whats happening over there?B:Where?A:A man running very fast from that supermarket.B:He might,Thank you!,
