听力原文： One winter day in 1891, a class at the training school in Massachusetts, USA, went into the gym for their daily exercises. Since the football season had ended, most of the young man felt they were in for a boring time. But their teacher James Nasmyth had other ideas. He had been working for a long time on a new game that would have the excitement of American football. Nasmyth showed the men a basket he had hung at each end of the gym and explained that they were going to use around European football At first, everybody try to throw ball into the basket no matter where he was standing .Pass ! Pass! Nasmyth kept shouting, blowing his whistle to stop the excited players. Slowly, they began to understand what was wanted of them. The problem with the new game, which was soon called basketball, was getting the ball out of the basket. They used ordinary fruit baskets with bottoms, and the ball, of course, stayed inside. At first, someone had to clime up every time a basket was scored. It was several years before someone came up with the idea of removing the bottom of the basket and letting the ball fall through. There have been many changes in the rules since then and basketball has become one of the world's most popular sports.

(30)

A．He took them to watch a basketball game.

B．He trained them to play European football.

C．He let them compete in getting balls out of a basket.

听力原文： Stress is a very normal part of life. Most people feel stress at some time in their lives. It doesn't come from an event itself, that is, from the things that are happening in our lives. It comes from the meaning we give to what has happened. We can experience stress any time we feel we don't have control. It can come from a feeling that we can do anything about a situation.

Stress is not just caused by our mental or emotional condition. It is also influenced by how tired we are, whether we have a balanced diet with enough vitamins and minerals, whether we get enough physical exercise and whether we can relax. If we feel stressed, there are several things that we can do. First, we need to learn how to relax and breathe slowly and smoothly.

We can also take some time out of our worried, busy schedule to notice the small things in life. Smell the air, look at the flowers, notice the small designs in the leaves on a tree -- these activities can do much to quiet us and to give ourselves a small break in a busy schedule.

We need to take care of our bodies. Being tired makes it easier for us to get sick and to develop physical problems related to stress. We need to get enough rest, eat well, and do some regular exercise.

Finally, we need to find what is causing the stress in our lives. Once we have found it, we need to begin to change that part of our lives. If we believe that we can control stress, we can begin to control our lives.

(34)

A．An unexpected event.

B．The understanding to an event.

C．The things that happen in our lives.

D．The influence of others.

第11题

听力原文： In the early 1800s, the paper industry was still using rags as its basic source

of fiber as it had for many centuries. However, the rag supply couldn’t keep up with the growing demand for paper. The United States alone was using 250 thou sand tons of rags each year. And a quarter of that had to be imported. It was clear that a new source of fiber was needed to keep up with the demand for paper. The answer to this problem turned out to be paper made from wood pulp, something that was abundantly available in North America. In Canada, the first wood pulp mill was set up in 1866, and it was immediately successful. But while wood pulp solved the problem of quantity, it created a problem of quality. Wood contains a substance called lignin. The simplest way to make large quantities of cheap paper involves leaving the lignin in the wood pulp. But lignin is acidic and its presence in paper has shorted the life expectancy of paper from several centuries for rag paper to less than a century for paper made from wood pulp. This means that books printed less than a hundred years ago are already turning yellow and beginning to disintegrate, even though books printed much earlier may be in fine condition. This is bad enough for the older books on your bookshelf, and it poses a huge problem for libraries and the collections of government documents, too.

The speaker mainly discusses ______.

A．the growth of the printing industry

B．the history of paper-making

C．the use of paper in the 19th century

D．the composition of wood fiber
