1 . 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.

2 . 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. |
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. |
A.A biography. | B.A book review. | C.A short story. | D.A science report. |

4 . Art is everywhere. Any public space has been carefully designed by an artistic mind to be both functional and beautiful. Why, then, is art still so widely considered to be "the easy subject" at school, insignificant to wider society, a waste of time and effort?
Art can connect culture with commercial products in a way that not many other things can; art generates money and holds significant emotional and cultural value within communities. When people attend a concert, they are paying for music, sure, maybe even hotel rooms, meals, and transport, but they also gain an incredible experience, a unique atmosphere and a memory that will go through the rest of their lives. People don't just want material things anymore, they want to experience life一the arts are a perfect crossover(交迭)between culture and commerce.
Furthermore, the arts can bring communities together, reducing loneliness and making people feel safer. Social bonds are created among individuals when they share their arts experiences through reflection and discussion, and their expression of common values through artworks in honour of events significant to a nation's experience.
The arts clearly have a pretty positive impact on physical and psychological health. It is found that people who frequent cultural places or participate in artistic events are more likely to gain good health compared to those who do not; more engagement with the arts is linked to a higher level of people's wellbeing. The Royal Society of Public Health discovered that music and art, when used in hospitals, help to improve the conditions of patients by reducing stress, anxiety and blood pressure.
Children who are involved with the arts make greater achievements in their education: those engaged with drama have greater literary ability while others taking part in musical practice exhibit greater skills in math and languages. Kids with preference for the arts have a greater chance of finding employment in the future. Participating in the arts is essential for child development; encouraging children to express themselves in constructive ways could help to form healthy emotional responses in later life.
Vital to human life, art is celebrated and used by nations across the world for various purposes. Life without art would be boring and dead still, for art is a part of what makes us human.

9 . “They tell me that you’d like to make a statue(塑像) of me-is that correct, Miss Vinnie Ream?”
The deep, gentle voice helped calm the nervous girl. Asking a favor of the President of the United States was no casual matter, especially for a seventeen-year-old girl.
“Yes, sir,” she replied, her dark eyes meeting his. “I wouldn’t have duo ask you, but my teacher, Mr. Mills, says I am ready. I plan to make it in an admirable manner. “
President Lincoln smiled. “Painters, sculptors-they’ve all tried to make the best of this ordinary face, but I’m afraid there’s not much hope. What did you have in mind, Miss Ream? A bust(半身像)?”
Before Vinnie could say yes, the President hurried on, a shade of apology in his voice.
“Of course-I shouldn’t have asked. A full-length pose would be much too big a project for a young woman your size. “
Vinnie’s face turned red. She realized she looked like a child, with her tiny figure. “Small does not mean weak, sir,” she defended herself. “I was born in the country of Wisconsin. I’ve driven teams of horses and carried water. Making a full-length clay(粘土) figure would not exhaust my strength-and that is what I intend to do!”
The President’s eyes, brightened at her show of spirit. “Sorry, madam, I have underestimated you as I didn’t know your background.”
But his smile faded as he rubbed his beard with bony fingers, in thought. “Miss Ream,” he sighed, “I’d like to let you do it, but as you know, we are in the middle of a war. How could I possibly take the time to pose for a sculpture now? I hardly have a minute to myself.”
Vinnie glanced around and noted the size of his office. “I work quickly,” she said. Her voice was soft but confident as she pointed to the corner near the windows. “If I were to bring my clay here and work for three hours every afternoon, I could complete most of the project while you are at your desk.”
The President seemed to consider her idea seriously. He got up and shook Vinnie’s hand warmly, “I’ve heard that you are a talented young woman, and I have found you charming and intelligent as well. I cannot make my decision immediately, but you will hear from me soon.”
The very next day, Vinnie received an invitation from the President.
