Dave woke up at 7:00 a. m. He had been chatting with a friend on the computer    1     nearly midnight last night so he was feeling quite tired but also rather nervous because this was a day of an    2    English exam at school. Dave had been studying very hard for this exam for the last two     3     so he thought he had a good chance of    4    it.

While Dave was traveling to school on the bus, he remembered that he had forgotten to take his wallet with him    5    he didn’t have any money to buy lunch. Just after this, his friend Lucas got on the bus.

“Can I    6    some money, Lucas?” asked Dave.

“Sure, no problem,”     7     Lucas. “Here you go.”

Two boys did the English exam. While they were    8    lunch, Dave asked Lucas if he thought the exam had been difficult. Lucas smiled and picked up the slice (薄片) of chocolate cake     9    he was eating.

“It was so easy. It was a     10    of cake!” said Lucas, smiling.
