听力原文： Recently a group of 17-year-old schoolboys decided to beat the world basketball time record. They are to play for 90 hours and add 6 hours to the record. Now could 18 boys play for almost 4 days without stopping？ The boys decided that each person would play for two and a half hours and then rest for two hours. They had to be able to sleep near the basketball hall, and they needed hot food and drink, day and night. Finally they started at 6 o' clock one evening.

The first night was very hard for the players. When it was their turn to rest, they were too excited to fall asleep at once. After sleeping for a short time, they had to play again. The nights were very long, when nobody was watching. The days were better, because plenty of people cheered the players' efforts. On the second night they fell asleep as soon as they stopped. Some of them had trouble with their hands and feet, but the only serious problem was a mental one. Each boy was thinking: What am I doing hero？ How can I play any longer？ After the third night the players knew they could finish the 90 hours. On the fourth night the play was very slow, but in the final hours it got better. For the last few minutes the players looked as fresh as when they started, they were tired, but very happy.
