In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week.
Yet many schools across the country have reduced their physical education programs. Criticism（批评） of the cuts has led in some places to efforts to give students more time for exercise, not less.
A study reported that life expectancy（寿命） has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in obesity（肥胖）, smoking and high blood pressure. They also blame differences in health services around the country.
A study found that only four percent of elementary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson is the executive director of the National Association for Sport and Physical Education. She says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training.
Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation. . How many reasons have caused some Americans’ life expectancy to fall?
| A．Three. | B．Four. | C．Five. | D．Six. |
The underlined part “that idea” (the last paragraph) refers to _______.
| A．competitive sports | B．a lifetime of activity |
| C．no-win situation | D．uncompetitive exercise |
. From the passage we can infer that _______.
| A．physically active children have more chances to be fit when growing up |
| B．most American schools let students take physical activity enough |
| C．the older a student is, the less exercise he gets |
| D．not all parents think exercise is good for students |
. The passage mainly tells us about _______.
| A．school and students’ health | B．how to make children healthy |
| C．American schools’ physical education | D．American students’ health |
How many people have I met who have told me about the book they have been planning to write but have never yet found the time ? Far too many.
This is Life, all right, but we do treat it like a rehearsal (排演) and, unhappily, we do miss so many of its best moments.
We take jobs to stay alive and provide homes for our families always making ourselves believe that this style of life is merely a temporary state of affairs along the road to what we really want to do. Then, at 60 or 65, we are suddenly presented with a clock and several grandchildren and we look back and realize that all those years waiting for Real Life to come along were in fact real life.
In America they have a saying much laughed at by the English：“Have a nice day” they speak slowly and seriously in their shops, hotels and sandwich bars. I think it is a wonderful phrase, reminding us, in effect, to enjoy the moment: to value this very day.
How often do we say to ourselves, "I'll take up horse-riding (or golf, or sailing) as soon as I get a higher position," only to do none of those things when I do get the higher position.
When I first became a reporter I knew a man who gave up a very well paid respectable job at the Daily Telegraph to go and edit a small weekly newspaper. At the time I was astonished by what appeared to me to be his completely abnormal (反常的) mental state. How could anyone turn his back
on Fleet Street in central London for a small local area？I wanted to know.
Now I am a little older and possibly wiser, I see the sense in it. In Fleet Street the man was under continual pressure. He lived in an unattractive London suburb and he spent much of his life sitting on Southern Region trains.
The first paragraph of the passage tells us that .
| A．we always try to find some time to write a book |
| B．we always make plans but seldom fulfill them |
| C．we always enjoy many of life's best moments |
| D．we always do what we really want to do |
The underlined phrase "turn his back on" (paragraph 6) most probably means .
| A．leave for | B．return to | C．give up | D．rely on |
The man ( paragraph 6) left his first job partly because he was .
| A．in an abnormal mental state | B．under too much pressure |
| C．not well paid | D．not respected |
What is probably the best title for the passage?
| A．Provide Homes For Our Family | B．Take Up Horse-riding |
| C．Value This Very Day | D．Stay Alive |
The iPhone, the iPad, the iPod, each of apple's products sounds cool and has become a pad (一时的风尚). Apple has cleverly taken advantage of the power of the letter “i”，-- and many other brands are following suit. The BBC’s iPlayer —which allows Web users to watch TV programs on the internet—adopted the title in 2008. A lovely bear—popular in the US and UK—that plays music and video is called “iTeddy”.A slimmed-down version of London’s Independent newspaper，was launched last week under the name “i”.
In general，single-letter prefix have been popular since the 1990s，when terms such as e-mail and e-commerce first came into use.
Most “i”products are targeted at young people and considering the major readers of the Independent’s “i”，it’s no surprise that they’ve selected this fashionable name.
But it’s hard to see what’s so special about the letter “i”.Why not use “a”，“b”or “c”instead？According to Tony Thorne，head of Language Center at King’s College，London，“i”works because its meaning has become ambiguous .When Apple uses “i”，no one knows whether it means internet，information，individual or interactive，Thorne told BBC magazines “even when Apple created the iPod，it seems it didn’t have one clear definition，”he says.
“However，thanks to Apple，the term is now associated with portability （轻便）， ”adds Thorne.
Clearly the letter “i”also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs，and we love personalized products for this reason.
Along with “Google”and “blog”，readers of BBC magazines voted “i”as one of the top 20 words that have come to define the last decade.
But as history shows，people grow tired of fads. From the 1900s to the 1990s，products with “2000”in their names became fashionable as the year was associated with all things advanced and modern. However，as we entered the new century，the trend inevitably disappeared.
We can infer that the Independent’s “i”is aimed at _______.
| A．young readers | B．old readers | C．fashionable women | D．engineers |
Sunday is more like Monday than it used to be. Places of business that used to keep daytime “business hours” are now open late into the night. And on the Internet, the hour of the day and the day of the week have become irrelevant. A half century ago in the United States, most people experienced strong and precise dividing lines between days of rest and days of work, school time and summer time. Today the boundaries still exist, but they seem not clear. 
The law in almost all states used to require stores to close on Sunday; in most, it no longer does. It used to keep the schools open in all seasons except summer; in most, it still does. And whether the work week should strengthen its legal limits, or whether it should become more “flexible,” is often debated. How should we, as a society, organize our time? Should we go even further in relaxing the boundaries of time until we live in a world in which every minute is much like every other? These are not easy questions even to ask. Part of the difficulty is that we rarely recognize the “law of time” even when we meet it face to face. We know as children that we have to attend school a certain number of hours, a certain number of days, a certain number of years — but unless we meet the truant officer （学监）, we may well think that we should go to school due to social custom and parents’ demand rather than to the law. As adults we are familiar with “extra pay for overtime working,” but less familiar with the fact that what constitutes （构成） “overtime” is a matter of legal definition. When we turn the clock forward to start daylight-saving time, have we ever thought to ourselves: “Here is the law in action”? As we shall see, there is a lot of law that has great influence on how we organize and use time: compulsory education law, overtime law, and daylight-saving law — as well as law about Sunday closing, holidays, being late to work, time zones, and so on. Once we begin to look for it, we will have no trouble finding a law of time to examine and assess. . By saying “Sunday is more like Monday than it used to be”, the writer means that .
| A．work time is equal to rest time |
| B．many people have a day off on Monday |
| C．it is hard for people to decide when to rest |
| D．the line between work time and rest time is unclear |
The author raises the questions in Paragraph 2 to introduce the fact that people ________ .
| A．fail to make full use of their time | B．enjoy working overtime for extra pay |
| C．are unaware of the law of time | D．welcome flexible working hours |
According to the passage, most children tend to believe that they go to school because they ______.
| A．need to acquire knowledge | B．have to obey their parents |
C．need to find companions | D．have to observe the law |
The underlined word “it” in the last paragraph probably refers to ___
_____ .

| B．overtime |
| C．a law of time |
| D．being late to work |
What is the main idea of the passage?
| A．Our life is governed by the law of time. | |

Movies in the theater get their recognition at awards ceremonies, such as the Oscars. But how about movies for phones? They are getting their turn at MoFilm—the first mobile film festival.
The first MoFilm competition received 250 entries from more than 100 countries. Entries were restricted to films that were five minutes or less in length—ideal 
forviewing and sharing on mobile phones. An independent jury then selected a shortlist of five film-makers. The winner was chosen from the shortlist by an audience voting using their phones.
New Platforms
The awards highlight the increasing impact that mobile phones are making in the entertainment industry. Many grassroots filmmakers start out with short films. They are thwarted by the lack of opportunities to screen their work. Therefore, mobile phones are increasingly being seen as a new platform for these short works.
It is a good place for anyone who wants to express themselves and find a way to have that expression be seen by a wide audience. Just think about how many people have mobile phones in the w
orld!
New Technology Advances
MoFilm is pioneering content for mobile and online services that is a world away from Hollywood. The majority of films made for mobiles are now short in length, taking into account the screen size. However this could be overcome as technology advances.
In the near future, longer films will likely be seen on the mobile phone. And there are mobile companies creating phones where users can watch movies at higher quality.
Wherever you see movies, one thing is certain: the quality of work, the simple ability at story telling, and the thing that inspires someone to tell a story can really come from anywhere. At the first MoFilm, .
| A．movies in the theater got their recognition |
| B．more than 100 countries took part in the competition |

Like distance runners on a measured course, all of us will move through time in a roughly predictable pattern.
In the first stage of our lives, we develop and grow, reaching toward the top of physical vitality (活力,生气).
After we grow up, however, the body begins a process of gradually wearing out.
A new awareness of physical fitness may help lengthen our years of health and vitality, yet nothing we do will work to stop the unavoidable force of aging.
Most of the changes of aging take place deep inside the body. The lungs become less able to take in oxygen. Powerful muscles gradually lose their strength. The heart loses power and pumps less blood. Bones grow easier to break.
Finally, we meet a stress, a stress that is greater than our physical resistance. Often, it is only a minor accident or chance infection (a disease caused by virus), but this time, it brings life to an end.
In 1932, a classic experiment nearly doubled the lifetime of rats, simply by cutting back the calories in their diet. The reason for the effect was then unknown.
Today, at the University of California at Berkley, Dr. Paul Seagle has also greatly lengthened the normal lifetime of rats. The result was achieved through a special protein limited diet, which had a great effect on the chemistry of the brain. Seagle showed that within the brain, specific chemicals control many of the signals that influence aging. By changing that chemical balance, the clock of aging can be reset.
For the first time, the mystery of why we age is being seriously challenged. Scientists in ma
ny fields are now making striking and far-reaching discoveries.
An average lifetime lasts 75 years, yet in each of us lies a potential for a longer life. If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years. What does the underlined word “it” refer to?
| A．Physical vitality. | B．Stress. | C．Aging. | D．Physical resistance. |
Which of the following is not a change of aging?
| A．The lungs become unable to take in oxygen. |
| B．People gradually lose their muscle strength. |
| C．The heart loses power and pumps less blood. |
| D．Bones tend to break more easily. |
The author believes the following except that ________.
| A．human’s life pattern is predictable |
| B．physical fitness can’t stop the force of aging |
| C．human’s lifetime will last longer than 75 years |
| D．all of the changes of aging take place deep inside the body |
How did Dr. Paul Seagle lengthen the lifetime of rats in his experiment?
| A．By limiting the protein in their diet. | B．By cutting the calories in their diet. |
| C．By resetting their clock of aging. | D．By keeping their physical fitness. |
