Bill and Fred were students at a university and they were friends. They didn’t have        money, so when it was time       their summer vacation, Bill said, “Let’s      our vacation in trailer(活动房车), Fred. It is      than a hotel. I can borrow my father’s trailer.” Fred was very happy, so they got into the trailer and began their vacation.
They wanted      early the next day to go fishing,       they didn’t have an alarm clock.“ That’s        , Bill,” Fred said, “ I have a good way. I’ll put      bread on the roof of the trailer tonight and they will wake us up in the morning.” Bill was very      , but he didn’t say anything. Fred was right. When it was at the first light, some       came down to eat the bread, and their noise on the roof (屋顶) of the trailer woke them up quickly.
