【題目】

Psychologists(心理學家) are interested in the reasons why some people like taking part in risky sports.

When they studied people who were learning to jump from a plane with a parachute, they found that the parachutists’ bodies produced large amounts of two hormones(激素), adrenaline(腎上腺素) and noradrenaline(去甲腎上腺素), just before they made their jump. These hormones help to prepare us for any sudden activity. Adrenaline increases the heart beat and provides more sugar for the muscles(肌肉), while noradrenaline makes us react(反應) more quickly. However, noradrenaline also supplies energy to a part of the brain which controls feelings of pleasure. A feeling of pleasure caused by this hormone makes certain people want to take part in dangerous sports.

Another possible reason is the level of excitement in part of the brain. According to some psychologists, the brain tries to manage a certain level of excitement. They believe that people who have a low level of excitement look for new experiences in order to fire themselves with excitement, but people who usually have a high level of excitement try to avoid risks in order not to become overexcited. If the psychologists are right, people with a low excitement level are the ones who enjoy taking part in dangerous sports and activities.

It is thought that people with low levels of excitement have a slower-reacting nervous system than people with higher levels. So it may be possible to find out your level of excitement by testing your nervous system. A quick way of doing this is to put some lemon juice on your tongue(舌頭). If you produce a lot of saliva(唾液), your nervous system has been affected(影響) by the lemon and so you probably have a high level of excitement; if you produce little saliva, you probably have a low excitement level. If you have a low level, you might enjoy taking part in risky sports. However, this does not mean that you have to try parachuting!

1Did the parachutists’ bodies produce large amounts of adrenaline and noradrenaline before they made their jump?

_________________________

2What does adrenaline increase and provide?

_________________________

3Why do people with a high level of excitement try to avoid risks?

_________________________

4How can people find out their level of excitement?

_________________________

5Who may enjoy taking part in risky activities?

【題目】Answer the questions (根據(jù)短文內容回答下列問題)

I’ve always wanted to try rock climbing, but never had time or money for it. But I’ve discovered a way to experience the thrill(興奮,緊張) of climbing rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer! Indoor climbers don’t climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms,

schools and camps have one.

You can climb in doors at any time of the year, no matter how the whether is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for rush(刺激感) they get. When I stand at the roof of the wall and look up, I’m always scared, but once I start climbing, fear changes to determination. With my___1___(心劇烈跳動), I reach the top and look down. I can’t stop grinning. I did it! Indoor climbing is a great workout(鍛煉). Climbing uses muscles(肌肉)that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones___2___(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls you climbing rope through something called a___3___(繩索控制器). The belay catches you if you slip. But make sure your partner knows how to use this equipment. And if you are a first-time climber, get some instruction before you begin.

1Is indoor climbing cheaper and safer than real rock climbing?

2On what do indoor climbers climb?

3What are the reasons that make the indoor climbing so popular?

4Who should always be with you when you climb?

5What does your partner do as you climb?
