Psychologists(心理学家) 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(肾上腺素) and noradrenaline(去甲肾上腺素), 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(反应) 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(舌头). If you produce a lot of saliva(唾液), your nervous system has been affected(影响) 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!

Do you have good friends? Do you sometimes feel so close to them that they are like family to you?
It turns out that this isn’t just an expression. A study by Yale University has found that you and your friends have more genes(基因) in common than strangers do. Researchers looked at the genes of 1, 932 people and compared them in pairs of unrelated friends and strangers. They found that friends have 1% of genes that match.
“1% of genes may not sound like much to the layperson(外行), but to geneticists(遗传学家) it is a larger number,” Professor Nicholas Christakis of Yale University told Discovery News. In fact, this is the same amount of genes you share with your fourth cousins, those who have the same great-great-great grandparents as you.
So do you happen to become friends with people who share your genes? Not at all. In fact, it is evolution(进化) that brings you together.
People who share certain genes also share skills and have similar likes and dislikes, researchers said. In ancient times, it was important that people who were alike stayed together. For example, people who had a similar susceptibility(易感性) to the cold were more likely to help each other build a fire, giving them a better chance to stay alive.
Researchers also found that among all the genes studied, those producing a change in sense of smell were the most similar in friends. This is probably because people who smell things in the same way are more easily drawn to similar environments. For example, people who like the smell of coffee may hang out at cafes(咖啡馆) more often and as a result are more likely to meet and become friends with each other.
With their findings, the team has developed an interesting test called the “friendship score”. It can help tell how big the chances are that two people will be friends by studying their genes.
So, here is a question for you: would you like to take this test and know in advance(提前) who your friends are going to be, or would you still prefer to learn about it by yourself and let time be the judge?
1.From the passage, we know that friends ________.
A.look like our cousin B.share 1% of genes with us C.feel close to our family D.can help us when we feel cold
2.According to the passage, the writer probably agrees ________.
A.we develop our friendship by chance B.our genes decide who we can make friends with
C.everyone should take the test called “friendship score” D.people sharing certain genes have skills and interests in common
3.The writer takes the example of ancient people in Paragraph 5 to ________.
A.study how ancient people dealt with the cold B.predict that similar environments lead to friendship
C.prove that it is evolution that brings friends together D.explain why ancient people gave each other chance to keep alive
4.Which of the following would be the best title for the passage?
A.Friendship: Its Influence on People and Behavior B.Friendship: Its Benefits to Teens and Decision Making
C.Friendship: Is It Necessary to Be Judged by Time? D.Friendship: Is It Possible to Be Influenced by Genes?
