Personal computers and the Internet give people new choices about how to spend their time.
Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.
E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool.
The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.
With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.
E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.
We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways.The purpose of this passage is to ________.
| A．explain how to use the Internet |
| B．describe the writer’s joy of keeping up with the latest technology |

The use of E-mail has made it possible for the writer to ________.
| A．spend less time working | B．have more free time with his child |
| C．work at home on weekends | D．work at a speed comfortable to him |
According to the writer, E-mail has an obvious advantage over the telephone because the former helps one ________.
| A．reach a group of people at one time conveniently |
| B．keep one’s communication as personal as possible |
| C．pass on much more information than the later |

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.From Paragraph 1, we learn that ________.
| A．diet products fail to bring out people’s potential | |
| B．people have difficulty in choosing diet products | |
| C．diet products are misleading people | D．people are fed up with diet products |
One psychological effect of diet products is that people tend to _____.
| A．try out a variety of diet foods | B．hesitate before they enjoy diet foods |
| C．pay attention to their own eating habits | D．watch their weight rather than their diet |
In Paragraph 3, “gain comes without pain” probably means ______.
| A．losing weight is effortless | B．it costs a lot to lose weight |
| C．diet products bring no pain | D．diet products are free from calories |
Diet products indirectly harm people physically because such products ______.
| A．are over-consumed | B．lack basic nutrients |
| C．are short of chemicals | D．provide too much energy |
Which of the following shows the structure of the passage?
Dear Hamilton,
We are fortunate that in such a large, high-pressure office we all get along so well. You are one of the people who keep the social temperature at such a comfortable setting. I don’t know anyone in the office who is better liked than you.
You can perhaps help with this. The collection of contributions towards gifts for employees’ personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral（葬礼）remembrance, four birthday gifts, and three graduation gifts.
It’s not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don’t know them outside the office, who wouldn’t even recognize their graduating children, their marrying daughters and sons, or their dead relatives.
This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today’s office setting.
Thank you for understanding.The underlined word “contributions” probably means ________.
| A．money | B．suggestions | C．reports | D．understanding |
Hamilton is expected to _______.
| A．show more kindness. | B．discontinue the present practice |
| C．quit being the organizer for gift giving | D．know more about co-workers’ families |
This is basically a letter of ________.
| A．apology | B．sympathy | C．appreciation | D．dissatisfaction |

Domestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.
Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.
As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.
Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (矿井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.
The domestication of horses has had great effects on societies. For example, horse were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new from of rapid transportation helped cultures spread around the world.Before domestication horses were ______.
| A．caught for sports | B．hunted for food |
| C．made to pull ploughs | D．used to carry people |
The author uses the Shetland horse as an example to show ______.
| A．it is smaller than the Clydesdale horse | B．horse used to have gentle personalities |
| C．some horses have better shaped than others | |
| D．horses were of less variety before domestication |
Horses contributed to the spread of culture by ______.
| A．carrying heavy loads | B．changing farming methods |
| C．serving as a means of transport | D．advancing agriculture in different areas |
The passage is mainly about _______.
| A．why humans domesticated horses | B．how humans and horses needed each other |
| C．why horses came in different shapes and sizes | |
| D．how human societies and horses influenced each other |
A
Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger at 2:30 AM. When I arrived to collect, I found the building was dark except for a single light in a ground floor window.
I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.
After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.
I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.
She kept thanking me for my kindness. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”
“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”
“It’s not the shortest way,” I answered quickly.
“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”
I quietly reached over and shut off the meter(计价器).
For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl.
Sometimes she’d ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing.
At dawn, she suddenly said,” I’m tired. Let’s go now.”
We drove in silence to the address she had given me.
“How much do I owe you?” she asked.
“Nothing.” I said.
“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.
Almost without thinking, I bent and gave her a hug. She held onto e tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”The old woman chose to ride through the city in order to ______.
| A．show she was familiar with the city | B．see some places for the last time |
| C．let the driver earn more money | D．reach the destination on time |
The taxi driver did not charge the old woman because he ______.
| A．wanted to do her a favor | B．shut off the meter by mistake |
| C．had received her payment in advance | D．was in a hurry to take other passengers |
What can we learn from the story?
| A．Giving is always a pleasure. | B．People should respect each other. |
| C．An act of kindness can bring people great joy. | |
| D．People should learn to appreciate others’ concern. |
Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part －drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.Watchers doubted if any of the vehicles could finish the race because .
| A．they did not have any human guidance |
| B．the road was not familiar to the drivers |
| C．the distance was too long for the vehicles |
| D．the prize money was unattractive to the drivers |
DARPA organized the race in order to .
| A．raise money for producing more robotic vehicles |
| B．push the development of vehicle industry |
| C．train more people to drive in the desert |
| D．improve the vehicles for future wars |
From the passage we know “robotic vehicles” are a kind of machines that .
| A．can do effortlessly whatever tasks living thing can |
| B．can take part in a race across 142 miles with a time limit |
| C．can show off their ability to turn themselves upside down |
| D．can move from place to place without being driven by human beings |
In the race, the greatest distance one robotic vehicle covered was .
| A．about eight miles | B．six miles |
| C．almost two miles | D．about one mile |
In the last paragraph, the writer implies that there is a long way to go .
| A．for a robotic vehicle to finish a 142-mile race without any difficulties |
| B．for a little child who has just learned to walk to reach the cookie on the table |
| C．for a robotic vehicle to deal with a simple problem that a little child can solve |
| D．for a little child to understand the importance of wiping apple juice off its face |
