听力原文： Hello everybody, and Welcome back to the thrilling game at the Tokyo Dome with the U.S. team. The game with the Japanese national team is going into the second half, 51 to 26. The U.S. Dream Team is made up of NBA veterans--supposedly the best we have to offers-but they need a miracle to dig themselves out of a hole and come back at this point.

Unfortunately for the Dream Team, their leading scorer, High-Fly Wilson, was ejected one minute into the second quarter after climbing into the stands and fighting with a spectator who had continually heckled Wilson for shooting three airballs in a row. Another bizarre moment came late in the second quarter when the Japanese center, Tomohiro Suzuki, suffered a concussion and was knocked out cold as he collided with the knee of one of his own teammates. There have also been several other injuries, including the loss of starting forward, Masa Harada.

Some of the coaches on the U.S. team are attributing the team's sluggish performance to some raw fish they had last night while attending a banquet in their honor. Who knows what'll be next. OK. It looks like we're ready for the second half.

(33)

A．They are leading in the game.

B．The score is really close.

C．The Dream Team is way behind.

D．They win the game.

听力原文： One way that scientists learn about man is by animals, such as mice, rats and monkeys. The scientists in this laboratory are experimenting on mice. They are studying the relationship between diet and health. At this time over one hundred experiments are going on in this laboratory.

In this experiment, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second is eating two cups, and the third group of mice is eating three cups.

After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Also they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years. The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years. The last group of mice spends most of the day eating or sleeping. They are not very ac tire. These mice are living longer than the scientists thought: about a year and a hell But they are not healthy. The experiment is still going on. The scientists hope to finish their studies in two years.

(33)

A．Mice.

B．Rats.

C．Monkeys.

D．A, B and C
