Mary is digging in the ground for a photo, when along comes John. Seeing that there is no one in sight, John starts to scream. John’s angry mother rushes over and drives Mary away. Once his mum has gone, John helps himself to Mary’s potato.

We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Mary and John are not humans. They’re African baboons(狒狒). ___1.___

John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others. ___2.___

Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated. ___3.___ An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”

Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe. ____4.___ But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.

It seems that trickery does play an important part in ape societies. ____5.___ Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.

A. In most cases the animal probably doesn’t know it is cheating.

B. An amusing example of this comes from a psychologist working in Tanzania.

C. And playing tricks is as much a part of monkey behavior as it is of human behavior.

D. So the psychologists asked his colleagues if they had noticed this kind of trickery.

E. The ability of animals to cheat may be a better measure of their intelligence than their use of tools

F. This use of a third individual to achieve a goal is only one of the many tricks commonly used by baboons.

G. Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

Fumbling with the buttons to find a good song while driving has been linked to increased risk of crashes, but is listening to music risky? “It depends on the music,” says a report published in the October issue of Accident Analysis & Prevention.

The study found teenage drivers who played their own music had significantly more traffic violations(违规) compared with background music designed by the researchers to minimize driving distractions, or no music.

Researchers at Ben-Gurion University in Israel recruited(招募) 85 drivers about 18 years old; just over half were male. The subjects were each assigned to drive six challenging road trips that were about 40 minutes long, accompanied by an experienced driving instructor. Music was played on four trips, two with selections from the drivers' playlists, mostly fast-paced vocals, and two with background music, which was a mixture of easy listening, soft rock and light jazz designed to increase driver safety. No music was played on two trips. Subjects rated their mood after each trip and in-car data recorders analyzed driver behavior and errors.

All 85 subjects committed at least three errors in one or more of the six trips; 27 received a warning and 17 required steering or braking by an instructor to prevent an accident. When the music was their own, 98% made errors; without the music, 92% made errors; and while listening to the safe-driving music, 77% made errors. Speeding, following too close, inappropriate lane use, one-handed driving and were the common violations.

The male subjects were more aggressive drivers and made more serious errors than female subjects. The teens played their own music at a very loud volume but significantly decreased the sound level when listening to the safe-driving music, researchers said. Mood ratings were highest on trips with driver-preferred music.

1.What is the key information the author wants to give in Paragraph 1?

A. Many drivers played their favorite music while driving.

B. Drivers shouldn’t search for the buttons to find a good song.

C. Song selection has nothing to do with increased risk of crashes.

D. Listening to certain types of music can increase drivers’ errors.

2.What does the underlined word “ subjects” refer to in this passage?

A. Something being discussed. B. People being written about.

C. People being tested. D. Areas of knowledge or study.

3.In the research, soft rock and light jazz are likely to _______.

A. increase drivers’ safety

B. add to the pleasure of driving

C. change drivers’ idea of safe driving

D. lower drivers’ guard against danger

4.It can be inferred from the passage that in the research ______.

A. the teens committed the most errors

B. the male were more skillful in driving

C. traveling with no music made the least errors

D. driver-preferred music increased the mood ratings
