He couldnt be over 50. may / might用于肯定句和否定句中。如： They may not know his address. 3.确定被推测时间，正确判断动词时态。. 对现在或将来的情况进行推测时，用“情态动词+ do”。 e.g You must be Mr. Smith. I was told to expect you. . 对此时此刻正在进行的情况进行推测时，用“情态动词+ be +动词-ing形式”。e.g She may be waiting for you in the entrance hall at the moment.对过去的情况进行推测时，用“情态动词+ have done”。 e.g I didnt see Alex.
