1 . As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.

“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.

Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.

“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.

“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”

Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

4. What does Dr. Nieca Goldberg suggest?

A．Making use of the findings.	B．Interviewing the study participants.
C．Conducting further research.	D．Clarifying the purpose of the study.

2 . Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.

Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.

That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately."

"Big change requires big ideas." he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.

An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.

"We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone."

1. Which of the following best describes the ban on drivers' texting in the US?

A．Ineffective.	B．Unnecessary.
C．Inconsistent.	D．Unfair.

2. What can the Textalyzer help a police officer find out?

A．Where a driver came from.	B．Whether a driver used their phone.
C．How fast a driver was going.	D．When a driver arrived at the scene.

3. What does the underlined word "something" in the last paragraph refer to?

A．Advice.

B．Data.

C．Tests.

D．Laws.

4. What is a suitable title for the text?

A．To Drive or Not to Drive? Think Before You Start

B．Texting and Driving? Watch Out for the Textalyzer

C．New York Banning Hand-Held Devices by Drivers.

D．The Next Generation Cell Phone: The Textalyzer-

3 . We journalists live in a new age of storytelling, with many new multimedia tools. Many young people don’t even realize it’s new. For them, it’s just normal.

This hit home for me as I was sitting with my 2-year-old grandson on a sofa over the Spring Festival holiday. I had brought a children’s book to read. It had simple words and colorful pictures — a perfect match for his age.

Picture this: my grandson sitting on my lap as I hold the book in front so he can see the pictures. As I read, he reaches out and pokes (戳) the page with his finger.

What’s up with that? He just likes the pictures, I thought. Then I turned the page and continued. He poked the page even harder. I nearly dropped the book. I was confused: Is there something wrong with this kid?

Then I realized what was happening. He was actually a stranger to books. His father frequently amused the boy with a tablet computer which was loaded with colorful pictures that come alive when you poke them. He thought my storybook was like that.

Sorry, kid. This book is not part of your high-tech world. It’s an outdated, lifeless thing. An antique, like your grandfather. Well, I may be old, but I’m not hopelessly challenged, digitally speaking. I edit video and produce audio. I use mobile payment. I’ve even built websites.

There’s one notable gap in my new-media experience, however: I’ve spent little time in front of a camera, since I have a face made for radio. But that didn’t stop China Daily from asking me last week to share a personal story for a video project about the integration of Beijing, Tianjin and Hebei province.

Anyway, grandpa is now an internet star — two minutes of fame! I promise not to let it go to my head. But I will make sure my 2-year-old grandson sees it on his tablet.

1. What do the underlined words “hit home for me” mean in paragraph 2?

A．Provided shelter for me.	B．Became very clear to me.
C．Took the pressure off me.	D．Worked quite well on me.

2. Why did the kid poke the storybook?

A．He took it for a tablet computer.	B．He disliked the colorful pictures.
C．He was angry with his grandpa.	D．He wanted to read it by himself.

3. What does the author think of himself?

A．Socially ambitious.	B．Physically attractive.
C．Financially independent.	D．Digitally competent.

4. What can we learn about the author as a journalist?

A．He lacks experience in his job.	B．He seldom appears on television.
C．He manages a video department.	D．He often interviews internet stars.

5 . Nowadays, in many places of the world, kids play soccer less than before.     1     Besides, many parents don’t know soccer’s real help to kids. Here are some reasons why kids should play the beautiful game.

Soccer is a team sport.

Teamwork is a life skill that kids need to learn. Being part of a team isn’t just about learning how to work together and share talents. It’s also about teaching kids how to face failure. It doesn’t end there, either. Being part of a team lets kids know how to take responsibility for their behavior.    2    

Soccer shapes motor skills (运动技能).

Nowadays, many kids prefer to stay in their rooms to have fun through TV, video games and smartphones.    3    It can cause them to lose out on valuable motor skills. By playing youth soccer, kids get a chance to develop their physical strength and motor skills.

    4    

Soccer can improve students’ concentration (专注) in the classroom. Besides, soccer is a fast-paced game, so kids can learn how to solve problems quickly. Plus, soccer is a sport which involves getting the ball from point A to point B. So kids’ visual-spatial (视觉空间) ability can be improved when they play the game, which can help them learn subjects like Physics.

Soccer improves the personal character.

The World Health Organization recommends kid get at least 60 minutes of exercises daily. This isn’t only for the physical benefits but also for the benefits to the personal character.     5     And these kids often have more self-confidence.

A．Youth soccer helps improve family relationships.

B．So they have less time outdoors for sports.

C．Soccer plays a part in school performance.

D．Being part of a team can help you make many friends.

E．One cause is that many kids are busy with their studies.

F．Usually kids who like sports such as soccer are more outgoing.

G．After all, if one player performs badly, the rest of the team will suffer for it.

9 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.

Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "

For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.

A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.

These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.

"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

10 . The United States rose to global power on the strength of its technology, and the lifeblood that technology has long been electricity. By providing long-distance communication and energy, electricity created the modern world. Yet properly understood, the age of electricity is merely the second stage in the age of steam, which began a century earlier.

"It is curious that no one has put together a history of both the steam and electric revolutions." writes Maury Klein in his book The Power Makers, Steam, Electricity, and the Men Invented Modern America. Klein, a noted historian of technology, spins a narrative so lively that at times it reads like a novel.

The story begins in the last years of the 18th century in Scotland, where Watt perfected "the machine that changed the world". Klein writes, "America did not invent the steam engine, but once they grasped its passwords they put it to more uses than anyone else. "

Meanwhile, over the course of 19th century, electricity went from mere curiosity to a basic necessity. Morse invented a code for sending messages over an electromagnetic circuit. Bell then gave the telegraph a voice. Edison perfected an incandescent bulls that brought electric light into the American home.

Most importantly, Edison realized that success depended on mass electrification, which he showed in New York City. With help from Tesla, Westinghouse's firm developed a system using alternating current, which soon became the major forms of power delivery.

To frame his story, Klein creates the character of Ned, a fictional witness to the progress brought about by the steams and electric revolutions in America during one man's lifetime. It's a technique that helps turn a long narrative into an interesting one.

1. What is Klein's understanding of the age of electricity?

A．It is closely linked to the steam age.

B．It began earlier than proper thought.

C．It is a little-studied period of history.

D．It will come to an end sooner or later.

2. What can be inferred about Ned?

A．He was born in New York City.	B．He wrote many increasing stories,
C．He created an electricity company.	D．He lived mainly in the 19th century.

3. What is the text?

A．A biography.

B．A book review.

C．A short story.

D．A science report.
