Can dogs and cats live in perfect harmony in the same home? People who are thinking about adopting a dog as a friend for their cat are worried that they will fight. A recent research has found a new recipe for success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two-thirds of the homes interviewed reported a positive relationship between their cat and dog.
However, it wasn’t all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals are just opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.
In homes with cats and dogs living peacefully, researchers observed a surprising behavior. They are learning how to talk each other’s language. It is a surprise that cats can learn how to talk ‘Dog’, and dogs can learn how to talk ‘Cat’.
What’s interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each other’s body signals, suggesting that the two may have more in common than was previously suspected. Once familiar with each other’s presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together on the sofa. They can easily share the same water bowl and in some cases groom (梳理) each other.
The significance of this research on cats and dogs may go beyond pets ─ to people who don’t get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.The underlined word swimmingly in Paragraph 1 is closest in meaning to ______.

Fido was now his master's constant companion in his walks, playing and skipping round him, and amusing him by a thousand sportive tricks . He took care, however, not to be troublesome by leaping on him with dirty paws, nor would he follow him into the parlor(客厅), unless invited. He also attempted to make himself useful by a number of little services. He would drive away the sparrows as they were stealing the chickens' meat; and would run and bark with the utmost fury at any strange pigs or other animals that offered to come into the yard. He kept the poultry, geese, and pigs from straying beyond their bounds and particularly from doing mischief in the garden. He was always ready to alarm Towzer if there was any suspicious noise about the house, day or night. If his master pulled off his coat in the field to help his workman, as he would sometimes do, Fido always sat by it, and would not suffer either man or beast to touch it. By this means he came to be considered as a very trusty protector of his master's property.
His master was once confined to his bed with a dangerous illness. Fido planted himself at the chamber-door, and could not be persuaded to leave it even to take food; and as soon as his master was so far recovered as to sit up, Fido, being admitted into the room, ran up to him with such marks of excessive joy and affection, as would have melted any heart to behold.
One hot day, after dinner, his master was sleeping in a summer-house , with Fido by his side. The building was old and crazy; the dog comprehended the danger, and began barking to awaken his master; and this not sufficing, he jumped up, and gently bit his finger. The master upon this started up, and had just time to get out of the door before the whole building fell down. Fido, who was behind, got hurt by some rubbish which fell upon him. Thus his love and fidelity had their full reward.According to the first paragraph,we can get the information that ________.
| A．Fido is too cautious to satisfy his master. |
| B．Fido did so many little things as not to please its master. |
| C．Fido is a very trusty protector of his master’s property |
| D．Fido often plays with sparrows,geese and pigs |
Which of the following description is NOT mentioned in the text?
| A．Fido didn’t leave its sick master’s chamber-door even refused to take food until its master recovery. |
| B．Fido saved its master when his master was sleeping in an old house |
| C．Fido drove away the wolf to protect its master’s sheep. |
| D．Fido drove away the sparrows as they were stealing the chickens’meat. |
The text is developed ______.
| A．by inference | B．by examples |
| C．by comparison | D．by figures |
Which one is the best title for the text?
| A．Saving the Master |
| B．The Loyal Dog |
| C．Protecting the Master’s Possession |
| D．The Duty of a Little Dog |

Multitasking
People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted (分心) and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”
The research led by Sanbonmatsu indicates that people who multitask .
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
When Sanbonmatsu and his colleagues conducted their research, they .
| A．assessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．analyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
According to Sanbonmatsu, people multitask because of their _.
| A．limited power in calculation |
| B．interests in doing things differently |
| C．inability to concentrate on one task |
| D．impulsive desire to try new things |
From the last paragraph, we can learn that multitaskers usually____ .
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |
| D．refuse to explain the reasons for their behavior |

The Brown Bear
My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An agreesive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back---- the sign (迹象) of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack----- The first time I felf panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family reminded clear-headed when panic could have led to a very different outcome.The brown bear approached the family in order to _______.
| A．catch shore birds |
| B．start an attack |
| C．protect the children |
| D．set up a barrier for itself |
The bear finally went away after it _______.
| A．felt safe | B．got injured |
| C．found some food | D．took away the camera |
The writer and his family survived mainly due to their ______ .
| A．pride | B．patience |
| C．calmness | D．cautiousness |

In today’s world of cellphones, mini laptops and MP3 players, most people have at least one timetelling tool with them. Since these devices are so common, is time running out for the 500yearold watch? According to some consumers, yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function”. Many young adults agree — and use their cellphones to tell time. Louis Galie, a senior vice president at Timex, said that fewer young people wear watches today than five years ago. As a result, some people claim that the watch industry is at a crossroads.
However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality timepiece that doesn't just keep good time. Fifty years ago, watchmakers boasted about their products' accuracy. But in recent years, the watch industry has transformed itself into an accessory business. And for many today, the image a watch communicates has become more important than the time it tells.
“Complications” — features that go beyond simple timekeeping — are an important part of a watch's image. Today's watches offer a lot of features that suit almost any personality. These features include altitude trackers, compasses, lunar calendars, USB drives, and even devices that measure the effectiveness of golf swings!
Creativity is also a key element in today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell time. It looks more like a futuristic (未来主义的) bracelet than a watch. Another Japanese watchmaker, EleeNo, makes a “handless” watch. Using a ring of circles to keep time, this watch makes an excellent conversation piece.
Whether a watch communicates fashion sense, creative flair or a love of sports, consumers want their timepieces to stand out. Nowadays, everyone has the same kind of gadget (小玩意儿) in their bags, so people want to make a statement with what's on their wrists. Will this interest in wrist fashion last? Only time will tell!
Why aren't watches popular with young people as before?
| A．Because watches cannot keep good time as cellphones, mini laptops and MP3 players. |
| B．Because watches are featured by the disadvantages of simple function. |
| C．Because watches are too expensive to afford. |
| D．Because watches don't have beautiful appearance as other modern timetelling tools. |
What does the underlined sentence in Paragraph 1 mean?
| A．Watchmaking becomes the sunrise industry. |
| B．Watchmaking is faced with the developing opportunity. |
| C．Watchmaking is facing a survival crisis challenge. |
| D．Watchmaking has a specific development target. |
It can be implied that ________.
| A．people will gradually lose interest in watches as they grow older |
| B．watchmakers scarcely change the development strategy for watches |
| C．today's watches are better than those in the past in quality |
| D．customers used to be more concerned with the quality of a watch than with its image |
The following qualities can make a watch popular EXCEPT ________.
| A．multifunction | B．accuracy |
| C．nice design | D．low price |

Eating 40 percent less food could extend a person`s life by 20 years, according to scientists.
Researchers at the Institute of Health Ageing at University College London are developing a treatment that they hope will fight the `disease` of getting older.
They are looking into how genetics（遗传学） and lifestyle can affect ageing and add years, possibly decades, to a person`s life.
Age-related diseases such as cardiovascular disease, cancer and neuro degeneration can also be treated, it is claimed.
They want to find out how the life of a rat can be increased by up to 30 percent simply by reducing its food intake.
Researcher Dr. Piper told the Independent : `If you reduce the diet of a rat by 40 percent it will live for 20 or 30 percent longer. So we would be talking 20 years of human life. This has shown on all sorts of animals, even Labradors(a kind of dog).`The scientists are also studying fruit flies, which share 60 percent of human genes and age in a similar manner, and mice.
They have already made the healthy lifespan(寿命) longer in both flies and mice by using drug treatments and a balanced diet. It is hoped that this combination will also work to extend(延长) human life. Dr. Piper said: `If we discover the genes involved with ageing, we should be able to delay ageing itself. This is what we`ve found.`
He added that the field of research into extending life is only a decade old, so remains `in theory . It is their special approach to treating all age-related diseases caused by the `disease` of ageing itself that sets their research apart.The author writes this text in order to_____.
| A．encourage people to eat as little as possible |
| B．tell people how harmful food is to their health |
| C．introduce an on-going research on delaying ageing |
| D．show how similar mice and humans are to each other |
How can people live longer according to the text?
| A．Exercise regularly. |
| B．Reduce their diet properly. |
| C．Vary their lifestyles constantly. |
| D．Change their genes completely. |
What does the underlined sentence in the last paragraph suggest?
| A．The research is effort-taking. |
| B．The result of the research is reliable. |
| C．The research has been done for a long time. |
| D．There’s a long way to go to put the theory into practice. |
