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 |
More than a hundred adults and kids gather for the Star Party on a cold evening, chattering excitedly as they stand in the dark on a Virginia hillside. The odd thing is, no one has turned on a flashlight, and no streetlights or house lights wink(闪烁) on around them.
These people have traveled to the countryside more than an hour from Washington, D. C., to get away from the glow of city lights. That's because they are attending a star party. Star parties are gatherings where professional and amateur astronomers set up their telescopes and invite people to come learn about the night sky. Getting away from light pollution, or artificial skylight from buildings for example, helps stargazers (看星星的人) see objects in the sky much better.
At this star party, Sean O'Brien of the National Air and Space Museum’s Einstein Planetarium starts off by asking the crowd to simply look up and take in all they can see. He points out plenty of things that can be seen without special equipment. Stars, satellites, and even the Andromeda galaxy(仙女座) can be found if you know where to look.
After that, several dozen astronomers offer close-up views. Each has focused their telescope on a different part of the sky. As kids take a look, the owner gives a mini-lesson.
O’Brien says you can have your own star party at home and learn a lot just by paying attention to what's happening up above. "Watch the sky as the seasons pass, and you will see that it changes," he says. "Or start with the moon. Notice when and where you are seeing it—maybe even in the early morning while you wait for the school bus. "What was it special about the Star Party ?
| A．It was organized by the local authority. |
| B．It was carried out without any lights. |
| C．It was so cold that people chatted to cheer up. |
| D．It was held in the town center of Virginia |
According to the passage, who were involved in the activity ?
a. some invited guests
b. some government officials
c. some experts in astronomy
d. those who were interested in astronomy
e. students who were major in agriculture
| A．a, c, d | B．a, d, e | C．b, d, e | D．c, d, e |
From the passage, we can infer that if you want to see the objects in the sky .
| A．you'd better escape from pollution and sunlight |
| B．you'd better follow Sean O'Brien's guidance |
| C．you'd better buy some advanced equipment |
| D．you'd better make use of your imagination |
Which of the following can be best describe what O'Brien says about discovering the stars'?
| A．Roman is not built in a day. |
| B．No pains, no gains. |
| C．All roads lead to Roman. |
| D．Time and tide wait for no man. |
A farm planted levels or floors is called a vertical（垂直的）farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards，rather than outwards，it requires much less space than a conventional farm.
The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.
There is a growing concern about the use of pesticides(杀虫剂) in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics(水耕法) could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.
In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words，we could grow crops in areas where we never could before.
Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.According to the passage, a vertical farm________.
| A．is mainly built outwards |
| B．is dependent on solar power |
| C．is planted on levels upwards |
| D．is only an environmental friendly farm |
Compared to the conventional farm, the vertical farm can________.
| A．depend far less on sunlight |
| B．greatly increase the use of soil |
| C．help to protect the limited gardens |
| D．reduce the use of harmful pesticides |
It can be learned from the passage that vertical farms________.
| A．have been put into use |
| B．only use hydroponics to grow food |
| C．need less room than conventional farms |
| D．may increase the transportation costs |
What would be the best title for the passage?
| A．Vertical farms for our future |
| B．Ways to deal with future problems |
| C．Vertical farms and green skyscrapers |
| D．Making Full Use of Our Limited Land |
Traditional fairytales(童话) are being given up by parents because they are too scary for their young children, a study found．
Research uncovered that one in five parents has got rid of old literature such as Snow White and the Seven Dwarves and Rapunzel in favor of more modern books．One third of parents said their children have been left in tears after hearing the gruesome details of Little Red Riding Hood．And nearly half of mothers and fathers refuse to read Rumplesliltshin to their kids as the themes of the story are kidnapping and killing．Similarly, Goldilocks and the Three Bears was also a tale likely to be left on the book shelf as parents felt it forgives stealing．
The survey of 2,000 adults was completed to mark the launch of the hit US drama GRIMM （ 格林童话剧） , which starts tonight at 9pm on Watch, and sees six drama series based on traditional fairytales．
The survey found a quarter of parents questioned wouldn’t consider reading fairytales to their kids．And 52 percent of the parents said Cinderella didn’t send a good message to their children as it describes a young woman doing housework all day．
Steve Hornsey, General Manager of Watch, said: "Bedtime stories are supposed to calm children down and send them off to sleep soundly．But as we see in GMMM, fairytales can be dark and dramatic so it’s understandable that parents worry about reading them to young children．As adults we can see the innocence in fairytales, but a five - year - old child could take them too literally．Despite the dark nature of classic fairytales as we see in GRIMM, good will defeat evil and there is always a moral to the story．"
The study also found two thirds of mums and dads try to avoid stories which might give their children nightmares．The most popular book read at bedtime is now 'The Very Hungry Caterpillar' by Eric Carle.
However half of parents said traditional tales are "more likely to have a strong moral message than a lot of modern kids' books, such as The Gruffato, The Hungary Caterpillar and the Mr. Men books．Classical works for children are being avoided by parents they think .
| A．they contain unmoral themes |
| B．they are terrifying |
| C．they encourage stealing, kidnapping and killing |
| D．they are tired of answering questions |
What does the underlined word "gruesome" mean?
| A．Very horrible | B．Very amusing |
| C．Very disappointing | D．Very amazing |
Which stories are the popular bedtime stories that parents like to tell their children now?
| A．Snow White and the Seven Dwarves and Cinderella |
| B．The Very Hungry Caterpillar and Little Red Riding Hood. |
| C．The Very Hungry Caterpillar andMr. Men |
| D．Goldilocks and the Three Bears and Cinderella |
According to Steve Hornsey , adults can see innocence in a fairy tale but a 5-year-old child might ______．
| A．think it is different from the reality |
| B．dislike it because it is scary |
| C．believe exactly what the tale says |
| D．feel there is a moral to the story |
Here are some of the world’s most impressive subways
| The Tokyo Metro and Toei Lines |
Features: The Tokyo Metro and Toei lines that compose Tokyo’s massive(庞大的)subway system carry almost 8 million people each day, making it the busiest system in the world. The system is famous for its oshiya— literally, “pusher”— who pushes passengers into crowded subway cars so the doors can close. And you think your commute (上下班路程) is hell. |
| The Moscow Metro |
Features: The Moscow Metro has some of the most beautiful stations in the world. The best of them were built during the Stalinist era and feature chandeliers(枝形吊灯), marble moldings and elaborate murals(精美的壁画). With more than 7 million riders a day, keeping all that marble clean has got to be a burden. |
| The Hong Kong MTR |
Features: The Hong Kong MTR has the distinction of being one of the few subway systems in the world that actually turns a profit. It’s privately owned and uses real estate development along its tracks to increase income and ridership. It also introduced “Octopus cards” that allow people to not only pay their fares electronically, but buy stuff at convenience stores, supermarkets, restaurants and even parking meters. It’s estimated that 95 % of all adults in Hong Kong own an Octopus card. |
| Shanghai Metro |
Features: Shanghai is the third city in China to build a metro system, and it has become the country’s largest in the 12 years since it opened．Shanghai Metro has 142 miles of track and plans to add another 180 miles within five years. By that .point, it would be three times larger than Chicago “L”. The system carries about 2.18 million people a day. |
| The London Metro |
Features: Londoners call their subway the Underground, even though 55 percent of it lies above ground. No matter when you’ve got the oldest mass-transit system in the world, you can call it anything you like．Trains started in1863 and they’ve been running ever since. Some 3 million people ride each day, every one of them remembering to “Mind the gap”. |

Some years ago I was offered a writing assignment that would require three months of travel through Europe. I had been abroad a couple of times，but I could hardly claim to know my way around the continent. Moreover, my knowledge of foreign languages was limited to a little college French.
I hesitated. How would I, unable to speak the language, totally unfamiliar with local geography or transportation systems, set up interviews and do research? It seemed impossible, and with considerable regret. I sat down to write a letter begging off. Halfway through, a thought ran through my mind： you can't learn if you don't try. So I accepted the assignment.
There were some bad moments. But by the time I had finished the trip I was an experienced traveler. And ever since，I have never hesitated to head for even the most remote of places，without guides or even advanced bookings, confident that somehow I will manage.
The point is that the new, the different, is almost scary by definition. But each time you try something, you learn, and as the learning piles up, the world opens to you.
I've learned to ski at 40, and flown up the Rhine River in a balloon. And I know I'll go on doing such things. It's not because I'm braver or more daring than others. I'm not. But I'll accept anxiety as another name for challenge and I believe I can accomplish wonders.The author accepted the assignment because _____
| A． he had never travelled abroad before |
| B． he hardly knew any foreign languages |
| C． he was familiar with any other country in Europe |
| D． he would learn something new and different by trying |
Which of the following statements is TRUE?
| A． The author had been abroad only twice. |
| B． The author thought the trip was hard but worthwhile. |
| C． The author admitted that anything different was terrible. |
| D． The author must be good at doing research and making interviews. |
We can infer from the text that the author is _____.
| A．awkward | B．generous | C．stubborn | D．brave |
What's the best title of the text?
| A．An Interesting Trip Abroad | B．My First Writing Assignment |
| C．Ready to Try and Challenge | D．How to Be Daring and Brave |
