【推荐2】It is not as simple as opening the door and hitting the track in winter. There are a few things you can do to ensure you are getting the most out of your run, and, importantly, not doing more harm than good.

Warm up, cool down

    1     Your muscles need some time to warm up when it's cold, so take it easy when you set off and do a few stretches （伸展）once you're finished.

Drink water

You might not feel hot, but that's because sweat evaporates （蒸发）more quickly into the chilly, dry air. So be sure to drink water before, during and after cold-weather workouts.     2     A belt bottle conveniently attaches to your waist so you don't have to carry it and can have a drink whenever you feel like it・

    3    

Running in cotton is a bad idea. Wear thin, breathable layers of synthetic （合成 的)）clothing that help protect you from the wind and snow, but still let out heat and moisture （水分）.Thirty percent of your body heat escapes through your hands and forty percent through your head. Wear a hat, or beanie （无边小便帽）, and gloves so your circulatory system can distribute warm blood to the rest of your body.     4    

Run into the wind

    5     . Obviously, it will be an easier passage home with some extra help from Mother Nature. But, more importantly, you won't have the wind in your face for the second half of your run, when you are more likely to be sweating and catch a chill.

A．Dress right

B．Keep warm.

C．Don't go too fast, too soon

D．Start and finish in the same way.

E．Don't wait to drink water until you feel thirsty.

F．Head out into the wind and come home with it at your back

G．On really cold days, wear a mask or scarf over your mouth to protect your face.

As the pace of life continues to increase, we are getting more and more stressed and we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But learning to live with a certain amount of stress is of great significance while relaxation is completely necessary for a healthy mind and body.

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing as it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.

The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first sight of unusual difficulties.

When exposed to stress, in whatever form, we react both chemically and physically. In fact, we make choice between “flight” and “fight” and in more primitive days, the choices made the difference between life or death. The crises(危机) we meet today are unlikely to be so extreme. But however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since serious condition as high blood pressure and heart disease have formed links with stress.

Since we can’t remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it to keep our mind and body healthy.

【推荐3】Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers(制造商) include in the small   print (印刷字体) that is often ignored when a new phone is bought. Apple, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, Black Berry, a manufacturer, recommends 2.5 centimeters.

If health issues arise from cell phone use, the possible effects are huge. Voice calls Americans chat on cell phones 2.26 trillion(万亿)minutes annually earn $109 billion for the wireless carriers.

Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect”. The book surveys scientific research and concludes the question is not settled.

Brain cancer is a concern that Ms.Davis examines. Over all，there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20 to 29 age group and a drop for the older population.

“Most cancers have multiple causes,” she says，but she points to laboratory research that suggests low energy radiation could damage cells that could possibly lead to cancer.

Children are more vulnerable(易受伤的)to radiation than adults, Ms.Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid(易吸收的液体). “No studies have yet been completed on cell phone radiation and children,” she says.

Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.

Ms.Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen(腹部)．

1. Why is the warning in the small print?

A．They don't want the users to pay attention to it.	B．There is not enough space for the warning.
C．They think people will not care about it.	D．The warning is not important at all.

2. Why do children easily be affected by radiation?

A．Because they haven't grown up.	B．Because they are too young to protect themselves.
C．Because they use cell phones more often than adults.	D．Because their skulls are thinner and their brains are easily hurt.

3. What can we conclude from the last paragraph?

A．Pregnant women should keep cell phones away.

B．People should use cell phones in the correct way.

C．If you are a child, you'd better text than make phone calls.

D．When you use a cell phone，use a wired headset or the phone's speaker.

4. What does the passage mainly talk about?

A．Be careful when using cell phones.

B．Don't hold your cell phone against your ear.

C．Rats exposed to radiation have damaged DNA in their brains.

D．Low energy radiation could damage cells that could lead to cancer.

【推荐1】People who grow up outside of cities are better at finding their way around than urbanites, a large study on navigation suggests. The results, described online on March 30 in Nature, hint that learning to handle environmental complexity as a child strengthens mental muscles for spatial skills.

Nearly 400,000 people from 38 countries around the world played a video game called Sea Hero Quest, designed by scientists and game developers as a fun way to collect data about people’s brains. Players piloted a boat in search of various targets.

On average, people who said they had grown up outside of cities, where they would have probably encountered lots of complicated paths, were better at finding the targets than people who were raised in cities.

What’s more, the difference between city residents and outsiders was most obvious in countries where cities tend to have simple layouts (布局), such as Chicago with its streets laid out at 90-degree angles. The simpler the cities, the bigger the advantage for people from more rural areas, cognitive scientist Antoine Coutrot of CNRS and his colleagues report.

Still, from these video game data, scientists can’t definitively say that the childhood environment is behind the differences in navigation. But it’s possible. “As a kid, if you are exposed to a complex environment, you learn to find your way, and you develop the right cognitive processes to do so,” Coutrot says.

Other factors have been linked to navigational performance, including age, gender, education and even a superior sense of smell. Figuring out these details will give doctors a more precise baseline (基准) of a person’s navigational abilities. That, in turn, might help reveal when these skills weaken, as they do in early Alzheimer’s disease, for instance.

1. What does the underlined word “urbanites” in Paragraph 1 refer to?

A．Those who live close to urban areas.

B．Those who are from rural areas.

C．Those who are raised in cities.

D．Those who long for urban life.

2. How did the researchers carry out the study?

A．By playing a game called Sea Hero Quest.

B．By gathering data from the video game.

C．By recording electrical activities in brains.

D．By comparing various targets of the game.

3. What can we learn from Paragraph 3 and 4?

A．City outsiders performed no better than city residents in the study.

B．Cities’ simple layouts gave city residents an advantage in the game.

C．There was no significant difference between city residents and outsiders.

D．The players’ performance had something to do with their earlier experience.

4. Which of the following can be the best title for the passage?

A．How environment impacts early childhood development

B．Why is early childhood education important for our future

C．When is the best time to obtain your navigational skills

D．Where you grew up may shape your navigational skills

【推荐2】At 13, Hawa Abdulai Yorke left her family’s home, in Ghana, Africa, to live with an aunt who promised to send her to school. Instead, the aunt put Yorke to work as her maid(佣人). Determined to go to school, Yorke returned home and began selling water in a nearby city to raise money for her education. However, her father spent the money she had earned on a motorcycle.

Yorkers story is familiar to girls growing up in Ghana. There, a girl’s place is in the home. Educating girls is considered a waste of money.

“It happens more than it should, where parents have money to send their girls to school but choose not to,” says Ryan Roach, a volunteer in Ghana, where nearly 55% of girls are not allowed to attend secondary school. Cultural beliefs say education is not a wise investment (投资).

The White House’s Let Girls Learn is working to change this view of girls’ education, in Ghana and in countries worldwide. Former First Lady Michelle Obama says parents have to be persuaded that girls’ education is a better investment than household labor. A study shows that for every year of secondary-school education, a girl’s earning power increases by 18%. Today, Let Girls Learn works in 13 countries, and there are plans to expand the program. Recently, Let Girls Learn hosted a 24-hour event to come up with creative solutions for the barriers (障碍) to girls’ education.

Yorke, now 22, is about to finish high school. Thanks to Let Girls Learn, she plans to attend college and study computer science. She says working alongside college students at the Let Girls Learn event strengthened her determination. “I’m focused on my books,” says Yorke. “I know if I study hard, I, too, can go to university and live a happy life.”

1. What was the attitude of Yorkers aunt towards girls attending school?

A．She was against it.	B．She had no idea of it.
C．She was in favor of it.	D．She considered it hard work.

2. According to Ryan Roach, the reason for girls not receiving enough education is that

A．they are too busy to go to school

B．their families are too poor to afford it

C．there are few secondary schools for girls

D．cultural beliefs prevent girls from attending school

3. What can we learn about Let Girls Learn?

A．It has spread all over the world.

B．It is a Ghana-based organization.

C．It aims to offer free education to girls.

D．It has got support from Michelle Obama

4. What’s Yorke’s next plan?

A．To further her studies.

B．To join in Let Girls Learn.

C．To write some books for girls.

D．To get a computer-related job.
