Have you ever had travel problems because your airplane was late? It is a common problem and it is getting worse. Airport delays make people angry and cost the country billions in lost work time.
The Federal Aviation Administration (FAA) is the government agency that oversees air travel. They studied the problem of airline delays.
They found eleven major problems and suggested eleven ways to fix them. Some of the problems are caused because different regions of the country do things differently. The regions don't talk to each other enough. Some of them need new computers.
Also, more planes are flying. A strong economy has more people using airplanes to get around. Airplanes are a form of mass transportation now, like trains and buses were in the past. More planes in the airport cause delays.
The airport in San Francisco is a good example. It is growing fast. Many people go through San Francisco to get to other places around the world. Ron Wilson of the San Francisco International Airport says, “If you've got 18 flights that all want to take off at 8：00 am and you're on the 18th plane in line, you're going to be 40 minutes late.”
Weather is another main reason for delays. Weather causes about 70% of delays. Fog or freezing rain can cause delays.
The first thing the FAA wants to do is take control away from the regions during heavy traffic times and bad weather. A national center would make decisions on things that affect the whole country. The FAA also wants to put more distance between planes in the sky when the weather is bad. This rule could cause even more delays.
The FAA knows that their solutions will not solve the problems with airport delays. But, they hope to make things better. There are just too many planes, too few traffic controllers, and not enough new technology.FAA found that some of the delay problems are caused by ________ between two regions.
| A．different languages |
| B．technical misunderstanding |
| C．misunderstanding of the rules |
| D．lack of communication |
Which of the following is NOT mentioned as a reason for airline delays?
| A．A growing number of flights. |
| B．Bad weather. |
| C．A growing population. |
| D．Lack of new technology |
From the passage we can infer that ________.
| A．FAA is a national center which controls all the flight matters |
| B．FAA has taken control to solve airport delays |
| C．in San Francisco, each plane will delay about 40 minutes |
| D．safety rules during bad weather may cause more delays |
Which of the statements best gives the idea of the passage?
| A．FAA should make decisions to stop airport delays. |
| B．Airport delays are on the rise. |
| C．Travel problems cost billions in lost work time. |
| D．FAA has taken control of air traffic nationwide. |
Every day we experience one of the wonders of the world around us without even realizing it. It is not the amazing complexity of television, nor the impressive technology of transport. The universal wonder we share and experience is our ability to make noise with our mouths, and so transmit ideas and thoughts to each other’s minds. This ability comes so naturally that we tend to forget what a miracle it is.
Obviously, the ability to talk is something that marks humans off from animal. Of course, some animals have powers just as amazing, Birds can fly thousands miles by observing positions of the stars in the sky in relation to the time of day and year. In Nature’s talent show, humans are a species of animal that have developed their own special act. If we reduce it to basic terms, it’s an ability for communicating information to others, by varying sounds we make as we breathe out.
Not that we don’t have other powers of communication. Our facial expressions convey our emotions, such as anger, or joy, or disappointment. The way we hold our heads can indicate to others whether we are happy or sad. This is so-called “body language”. Bristling(直立的) fur is an unmistakable warning of attack among many animals. Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering.
Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display. Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skill? Biologist can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history.According to the passage, the wonder we take for granted(认为理所当然) is________.
| A．our ability to use language |
| B．the miracle of technology |
| C．the amazing power of nature |
| D．our ability to make noises with mouth |
What feature of “body language” mentioned in the passage is common to both human and animals?
| A．Lifting heads when sad. |
| B．Keeping long faces when angry. |
| C．Bristling hair when ready to attack. |
| D．Bowing heads when willing to obey. |
What can be inferred from Paragraph 3?
| A．Body language is unique to humans. |
| B．Animals express emotions just as humans do. |
| C．Humans have other powers of communication. |
| D．Humans are no different from animals to some degree. |
This passage is mainly about _______.
| A．the development of body language. |
| B．the special role humans play in nature |
| C．the power to convey information to others |
| D．the difference between humans and animals in language use |
Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化物) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea’s effect on everything from cholesterol (胆固醇) to the risk of certain cancers, with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”, or problems with daily activities or basic needs, such as dressing or bathing.
Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (缓冲) against disability, Tomata’s team did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting (凝固).What can be learned from the passage?
| A．Antioxidant chemicals can lead to disease. |
| B．Those who often drank green tea can’t develop “functional disability”. |
| C．“Functional disability” is related to problems with daily activities or basic needs. |
| D．People who drank at least five cups a day are not likely to become functionally disabled. |
What does the fifth paragraph mainly tell us?
| A．How the study was proved. | B．Why green tea-lovers can keep agile. |
| C．What healthier diets include. | D．How to lower disability risk. |
What have the Researchers discovered?
| A．Those who drank green tea can't develop “functional disability”. |
| B．Green tea alone kept people agile as they grew older. |
| C．How green tea might offer a buffer against disability. |
| D．Green tea extracts (提取物) seem to increase leg muscle strength in older women. |
In the United States, friends can be close, constant and real. But if they move live far away from each other, little by little, they will not be as close as before. But neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while, then no more. If two people meet again by chance, even years later, they will be delighted and pick up the friendship again.
In America, you can feel free to visit people's homes, share their holidays and enjoy their delicious food. If you are invited to a party, just accept their hospitality(款待) for various reasons, such as crowded space, language difficulties or family customs. It is often considered more friendly to invite a person to one's home than to go to a public place. So, if your host or hostess brings you home, do not feel that you aren’t treated well. You know, strangers are not invited into the home.
Don't feel neglected if you do not find flowers awaiting you in your hotel room either. Flowers are very expensive there, hotel delivery is not certain, and arrival times are often delayed, so flowers are not often sent as a welcoming touch. Please do not feel unwanted! In fact, signs outside change in different lands, but the welcome in the heart is real and valuable. You will find friendships _______ in America if they are not near each other.
| A．die suddenly | B．come back | C．disappear gradually | D．last forever |
The underlined part in the last paragraph can be replaced by “______”.
| A． Don’t feel you are paid little attention |
| B．Don’t accept an invitation quickly |
| C． Don’t feel you should be treated well |
| D．Don’t pay much attention to the flowers |
Which of the following is the best title for this passage?
| A．American Hospitality | B．American Friendships |
| C．American Invitation | D．American Welcome |
Do you want to live another 100 years or more? Do you want to live never to die? Some experts say, it will be not a dream one day. Modern technology will make it come true. Man will live more years beyond what is now seen as the natural limit of the human life.
“ I think we are knocking at the door of immortality,” said Michael, a professor and author of two books on human life expectancy. “I think by 2075 we will see it and it’s no longer a dream. Human’s life expectancy may have not limit.”
At the meeting in San Francisco, Donald Louria, a professor at New Jersey Medical School said advances in using genes as well as other technology make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 300 or 500 years.”
However, many scientists are doubtful about it and say the human body is just not designed to last more than about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and other parts of the body will finally lead all humans to death.
Scientists also hold different opinions on what kind of life man might live. “If you pass 120, you know; could you be healthy enough to have good quality of life? It’s a big question.” said Leonard Poon, director of the university center. “At present people who could get to that point are not in good health at all.” The underlined word in the second paragraph probably means _____.
| A．dying slowly | B．living longer | C．living forever | D．dying quickly |
Donald’s attitude is that______.
| A．human beings may never die in the future |
| B．it is not certain how long humans can live |
| C．the human body can last about 120 years |
| D．it is possible for man to live longer in the future |
What would be the best title for this text?
| A．Living longer or not | B．Science and long living |
| C．No limit for human life | D．Healthy lifestyle and living |
In the last sentence “get to that point” means ____.
| A．get that idea | B．get to 120 years old |
| C．know how to live forever | D．have good quality of life |
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 |
| C．get an advantage over others in job-hunt | D．attract more admirers |
According to the passage, the author believes that ______.
| 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 |
