      James and Harry came to London and stayed in the same hotel.  

      James came in in a great hurry one evening. A friend had offered him a ticket for a play. He saw a

1etter on the hall table. "That will keep till I get back,"he thought，"no time to lose now." And he went

off．

       Harry came in a minute after James. There was a letter for him，too，which he opened at once. It

was from the secretary(秘书)of a company, offering him a post(职位)in their office. He Was told to be

there at 10 a.m. the next morning, as there were others who wanted the job.

      James got back from the play at midnight. He was sleepy. "That letter can be opened in the morning,"

he thought. The next morning when he woke up, he at once jumped out of bed, tore(撕) it open-his face

fell . It was a similar letter to the one Harry had received the night before. But James’ chance was gone. It was five to ten, and he could never be at the office in time.
