Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did
It best .Those tested with their animal friends had smaller change in blood pressure and returned Most quickly to baseline heart rates .With pets in the room ,people also made fewer math mistakes Than when doing in front of other companions. It seems people feel more released(放松)around Pets, says Allen, who thinks it may be because pets don't judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a Year studying 36 fat people and were put on a diet-and-exercise programs; a separate group of 56 fat people without pets were put on a diet program. On average，people lost about 11 pounds， Or 5% of their body weight .Their dogs did even better，losing an average of 12 pounds，more then 15%of their body weight .Dog owners didn't lose any more weight than those without dogs but ,say Researchers，got more exercise overall –mostly with their dogs –and found it worth doing.

It’s easy to see how to help others, but what about those whose needs aren’t so obvious? This story may have happened a while back, but it was a lesson which has stayed with me and helped me ever since.
It was Thanksgiving and I was volunteering with my parents at a shelter for the poor. We stood behind the counter dishing out hot food to whoever came in. Most of our dinners looked like they had been having hard times, their clothes old, worn and dry. In short, they looked poor!
Then, a man came in, who looked anything but poor. He was well dressed, wearing an expensive suit. I wondered what he was doing there and my jaw dropped in amazement when he joined the line for food. The closer he came to my service station, the more I muttered. What was this man doing? I wanted to know. Surely he wasn’t going to take food.
Then my mother quietly took me to one side. She said, “ You have assumed that the needs of the people who come here must be purely physical: hunger, inadequate shelter and needs are emotional? What if he needs comfort, friends, or just to be among other human beings?” Her words hit me like a ton of bricks! About a week later the shelter received a large donation from an anonymous source. I can’t help but wonder if it came from that man. I felt like I should apologize to the man, but I didn’t.
Now, whenever I meet others, I remember my mother’s words and try to send kindness and blessings to them, regardless of how they look. Needs aren’t always visible. But kindness always makes a difference.The task of the author at the shelter was to_______.
| A．decide whether dinners looked poor |
| B．learn life experience there |
| C．serve hot food to the poor |
| D．help parents order dishes |
When the man waited in line, how did the author feel?
| A．Surprised | B．Pitiful | C．Excited | D．Angry |
The author felt he should apologize to the man, because he_______.
| A．was asked to do so by his mother |
| B．gave the man food much less than others |
| C．realized something was wrong with the man |
| D．knew later that the man might go there to donate |
What can we infer from the last paragraph?
| A．We should show others kindness whatever their needs are |
| B．Some needs can’t be known clearly at times |
| C．Needs can always be met by kindness |
| D．We should find out others’ needs |
Recently I spoke to some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had.
Given that I teach students who are training to be doctors, I was surprised to find that most thought that they would not be able to get the jobs they wanted without “outside help”. “What kind of help is that?” I asked, expecting them to tell me that they would need a relative or family friend to help them out.
“Surgery(外科手术)”, one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job. One girl told me that she was considering surgery to increase her height. “They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it regrows, you can get at least 5cm taller!”
At that point, I was shocked. I am short, I can’t deny that, but I don’t think I would put myself through months of agony(痛苦) just to be a few centimeters taller. I don’t even bother to wear shoes with thick soles, as I’m not trying to hide the fact that I am just not tall! It seems to me that there is a trend toward wanting “perfection”, and that is an ideal that just does not exist in reality.
No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that “perfection” is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his chosen career.We can know from the passage that the author works as ______.
| A．a doctor | B．a model | C．a teacher | D．a reporter |
Many graduates today turn to cosmetic surgery to______.
| A．marry a better man\woman |
| B．become a model |

| A．everyone should purchase perfection, whatever the cost |
| B．it’s right for graduates to ask for others to help them out in hunting for jobs |
| C．media are to blame for misleading young people in their seeking for surgery |
| D．it is one’s appearance instead of skills that really matters in one’s career |
What does the author think of his height?
| A．He hates to be called a short man. |
| B．He tries to increase his height through surgery. |
| C．He always wears shoes with thick soles to hide the fact. |
| D．He just accepts it as it is |
Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.The text mainly discusses the relationship between ______ .
| A．heart problems and air quality | B．heart problems and exercising |
| C．heart problems and smoking | D．heart problems and fatty food |
The underlined word “modest” in Paragraph 3 most probably means ______ .
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
What can we learn from the text?
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking. |
| D．Stricter regulations on pollutants should be made. |
The author’s purpose of writing the text is most likely to _______.
| A．inform | B．persuade | C．describe | D．entertain |
When my brother and I were young, my mom would take us on Transportation Days.
It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the train, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home—our first car ride of the day.
The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal (多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence—the product of a childhood not spent exploring subway tunnels.
Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just lightrail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox—and often an inadequate one, limiting both your mobility and your wallet.
On Transportation Days, we might stop for lunch on Chestrut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river?
I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me. According to the writer, what was the greatest benefit of her Transportation Days?
| A．Building confidence in herself. |
| B．Reducing her use of private cars. |
| C．Developing her sense of direction. |
| D．Giving her knowledge about vehicles. |
The underlined word “paralyzed”(in Para.5) is closest in meaning to “________”．
| A．displayed | B．justified | C．ignored | D．ruined |
Which means of transportation does the writer probably disapprove of?
| A．Airplane. | B．Subway. | C．Train. | D．Car. |
On a hill 600 feet above the surrounding land, we watch the lines of rain move across the scene, the moon rise over the hills, and the stars appear in the sky. The views invite a long look from a comfortable chair in front of the wooden house.
Every window in our wooden house has a view, and the forest and lakes seldom look the same as the hour before. Each look reminds us where we are.
There is space for our three boys to play outside, to shoot arrows, collect tree seeds, build earth houses and climb trees.
Our kids have learned the names of the trees, and with the names have come familiarity and appreciation. As they tell all who show even a passing interest, maple（枫树）makes the best fighting sticks and white pines are the best climbing trees.
The air is clean and fresh. The water from the well has a pleasant taste, and it is perhaps the healthiest water our kids will ever drink. Though they have one glass a day of juice and the rest is water, they never say anything against that.
The seasons change just outside the door. We watch the maples turn every shade of yellow and red in the fall and note the poplars（杨树）putting out the first green leaves of spring. The rainbow smelt fills the local steam as the ice gradually disappears, and the wood frogs start to sing in pools after being frozen for the winter. A family of birds rules our skies and flies over the lake. What can be learned from Paragraph 2?
| A．The scenes are colorful and changeable. |
| B．There are many windows in the wooden house. |
| C．The views remind us that we are in a wooden house. |
| D．The lakes outside the windows are quite different in color. |
By mentioning the names of the trees, the author aims to show that ______ .
| A．the kids like playing in trees |
| B．the kids are very familiar with trees |
| C．the kids have learned much knowledge |
| D．the kids find trees useful learning tools |
What does the underlined sentence in the last paragraph mean?
| A．The change of seasons is easily felt. |
| B．The seasons make the scenes change. |
| C．The weather often changes in the forest. |
| D．The door is a good position to enjoy changing seasons. |
What is the main purpose of the author writing the text?
| A．To describe the beauty of the scene around the house. |
| B．To introduce her children’s happy life in the forest. |
| C．To show that living in the forest is healthful. |
