Our love of music and appreciation of musical harmony is learnt and not based on natural ability, a new study by University of Melbourne researchers has found. The researchers said previous theories about how we appreciate music were based on the physical functions of sound, the ear itself and a born ability to hear harmony.
The study shows that musical harmony can be learnt, and it is a matter of training the brain to hear the sounds. So if you thought that the music of some foreign culture (or Jazz) sounded like the crying of cats, it’s simply because you haven’t learnt to listen by their rules.
The researchers used 66 volunteers with a range of musical training and tested their ability to hear combinations of notes(音符) to determine if they found the combinations familiar or pleasing. They found that people needed to be familiar with combinations of notes. If they found the notes unfamiliar they also found the sound unpleasant. This finding put an end to centuries of theories claiming that physical functions of the ear determine what we find attractive.
The study found that trained musicians were much more sensitive to unpleasant notes than non-musicians. When they couldn’t find the note, the musicians reported that the sounds were unpleasant, while non-musicians were much less sensitive. This shows the importance of training or nurturing(培养) the brain to like particular sound of combinations of notes, like those found in jazz or rock.
Depending on their training, a strange chord(和弦) sound was pleasant to some musicians, but very unpleasant to others. This showed us that even the ability to hear a musical note is learnt.
To confirm this finding, they trained 19 non-musicians to find the notes of a random selection of western chords. Not only did the participants’ ability to hear notes improve rapidly, afterward they reported that the chords they had learnt sounded more pleasant -- regardless of how the chords were played.
The question of why some combinations of musical notes are heard as pleasant or unpleasant has long been debated. “We have shown in this study that for music, beauty is in the brain of the beholder(观看者)”, a researcher said. According to the study, people find foreign music quite unpleasant because_____.
| A．they hear the music much too often |
| B．they don’t like the person playing it |
| C．they have no idea about how to listen |
| D．they have no born musical ability at all |
Although non-musicians were less sensitive to music, they can still_____.
| A．be trained to like particular music |
| B．make friends with real musicians |
| C．find the beauty of chords without training |
| D．enjoy the beauty of music when played by musicians |
The 19 non-musicians were trained in order to show_____.
| A．the brain likes particular combinations of notes |
| B．not a strange note was pleasant to all musicians |
| C．how the chords were played was very important |
| D．people’s ability to hear a musical note can be learnt |
What is the main idea of the passage?
| A．Love of musical harmony can’t be taught. |
| B．Love of music is not natural but nurtured. |
| C．Listening to music can improve your brain. |
| D．You can be a musician without being trained. |
Communications technologies are far from equal when it comes to conveying the truth. A recent research shows people tend to tell more lies in phone conversations than they are in emails. The fact that emails are automatically recorded and can come back to haunt you appears to be the key to the finding.
Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week. In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told. Hancock then worked out the number of lies per conversation for each medium. He found that lies made up 14 percent of emails, 21 percent of instant messages, 27 percent of face-to-face interactions and an astonishing 37 of phone calls.
His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists. Some expected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the detachment（非直接接触）of emailing would make it easier to lie. Others expected people to be more in face-to-face exchanges because we are most practiced at that form of communication.
But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time. “People appear to be afraid to lie when they know the communication could later be used to hold them to account,” he says. This is why fewer lies appear in email than on the phone.
“People are also more likely to lie in real time in an instant message or phone call than if they have time to think of a response,” say Hancock. He found many lies are spontaneous responses to an unexpected demand, such as, “Do you like my dress?”
Hancock hopes his research will help companies work out the best ways for their employees to communicate. For instance, the phone might be the best medium for sales where employees are encouraged to stretch the truth. But, given his result, work assessment where honesty is a priority, might be best done using email.Hancock’s study focuses on ______.
| A．the consequences of lying in various communications media |
| B．the success of communications technologies in conveying ideas |
| C．people are less likely to lie in instant messages |
| D．people’s honesty levels across a range of communications media |
Hancock’s research finding surprised those who believed that ______.
| A．people are less likely to lie in instant messages |
| B．people are unlikely to lie in face-to-face interactions |
| C．people are most likely to lie in email communication |
| D．people are twice as likely to lie in phone conversations |
According to the passage, why are people more likely to tell the truth through certain media of communication?
| A．They are afraid of leaving behind traces of their lies. |
| B．They believe that honesty is the best policy. |
| C．They tend to be relaxed when using those media. |
| D．They are most practiced at those forms of communication. |
It can be inferred from the passage that ______.
| A．honesty should be encouraged in interpersonal communications |
| B．more employers will use emails to communicate with their employees |
| C．suitable media should be chosen for different communication purposes |
| D．email is now the dominant medium of communication within a company |
Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very , very easy. Such supercharged clothing is one of the products that could be created using “wearable robotics” technology.
Designed to improve a person’s senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you’re going to do, then helps you do it better.
“A superman suit would be the final result in wearable robotics,” said Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory（橡树林国家实验室）, US. While these suits are at least ten years away, in some areas the technology is already in use.
Researchers are developing artificial arms and legs that allow old, disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier.
A robot is a device that responds to a command. You’re probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control.
Wearable robotics goes further. Instead of just receiving information through a wire or remote control, the robotic device can send information back to its controller.
Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action.
In this way, scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do.Which of the following can replace the underlined word “ supercharged” in Paragraph one?
| A．expensive | B．overcharged | C．advanced | D．full of electricity |
Products resulting from this wearable robotics technology do not include ___________.
| A．remote controls | B．hearing aids |
| C．wearable robot legs | D．superman suits |
From the passage, we can infer that_______________.
| A．it will be ten years before robotic devices are in use |
| B．the wearable robotics technology has been employed in some areas |
| C．the robots in the robotic devices will do whatever you want to do |
| D．people must become lazier and less healthier in the future |

Friendship can deeply affect the physical and mental health of both men and women. Studies show that people who have no friends or who are lonely, are more likely to die earlier, get sick more often and suffer greater physical wear and tear（折磨）than those who have a support system of friends.
Sometimes, family members may be more likely to give you advice or tell you what you don’t want to hear. It may not be as good as a friend who will listen to you and guide you, but support your decisions anyway. The most important elements about friendship are those who suffer support and do not judge your decisions based on society.
One reason for the link between social support and good health practice seems to be that people who feel cared for by others are less stress-out and are protected against the symptoms（症状）of depression and loneliness.
Generally, women benefit most because of how they deal with stress. Women are more social in how they deal with stress than men, while men are more likely to have a “fight or flight” reaction. Women also tend to have larger, denser social network, in which more people know each other and help each other, while men typically have smaller groups of friends and will rely on their wives or other important people for more support. While all these affect people psychologically（心理上）, friendship brings comfort that reduces the ill effects of stress, and the sex difference also contributes to the difference in the length of one’s life time.In the author’s opinion, a real friend should _________.
| A．tell you what to do even if you refuse to hear it. |
| B．try to persuade you to change your mind quickly. |
| C．judge your decision according to his/her experience. |
| D．give you advice but respect your own decision. |
Women benefit more from friendship than men because _________.
| A．women are always cared for by more people than men. |
| B．women are usually less stress-out when staying with others. |
| C．women are more likely to solve problems with friends’ help |
| D．women can always keep more long-life friendship than men |
According to the passage we can infer that _______.
| A．it’s good for women to tell men what they should do or not |
| B．friends are always more important than family members |
| C．men don’t want to share their problems with many people |
| D．the trend that women can live longer makes them more relaxed |
This passage mainly talks about _________.
| A．why people should develop friendship |
| B．when friendship affects people’s health |

I was in a strange city and I didn't know the city at all, and what is more, I could not speak a word of the language. After having spent my first day in the town-centre, I decided to lose my way on my second day, since I believed that this was the simplest way of getting to know the strange city.
I got on the first bus that passed, rode on it for several stops, then got off it and walked on. The first two hours passed pleasantly enough. Then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way. The trouble was that the only word I knew of the language was the name of the street in which I lived and even then I pronounced it badly.
I stopped to ask a friendly-looking newspaper-seller. He smiled and handed me a paper. I shook my head and repeated the name of the street and he put the paper into my hands. I had to give him some money and went on my way. The next person I asked was a policeman. The policeman listened to me carefully, smiled and gently took me by the arm. There was a strange look in his eyes as he pointed left and right and left again. I thanked him politely and began walking in the direction he pointed.
About an hour passed and I noticed that the houses were getting fewer and fewer and green fields were appearing on either side of me. I had come all the way into the countryside.
The only thing left for me to do was to find the nearest railway station.The writer believed that if you wanted to get to know a strange city, ______.
| A．you should go everywhere on foot | B．you should have a map |
| C．you should ask people the way | D．you should get lost |
The newspaper-seller ______.
| A．could understand what he said | B．didn't know what he said |
| C．laughed at him | D．didn't want to take the money |
The writer's real trouble was that _______.
| A．he couldn't speak the language | |
| B．he followed the policeman's direction | |
| C．he took the wrong bus | D．he left the town-centre |
The policeman ______.
| A．didn't help him | B．pointed at him |
| C．didn't understand what he really meant | D．didn't know the way |
