As millions of Americans crowd into the gym armed with New Year’s resolutions to get in shape, medical experts are offering an additional reason for exercise: Regular workouts may help fight off colds and flu, reduce the risk of certain cancers and chronic diseases and slow the process of aging.

Physical activities have long been known to help maintain a healthy weight and reduce stress. Now, a growing body of research is showing that regular exercise—as simple as a brisk 30-to-45-minute walk five times a week—can boost the body’s immune system, increasing the circulation of natural killer cells that fight off viruses and bacteria. And exercise has been shown to improve the body’s response to the influenza vaccine (疫苗), making it more effective at keeping the virus at bay.

Medical experts warn inactivity poses as great a health risk as smoking, resulting in heart disease, cancer, depression, and diabetes. The Centers for Disease Control and Prevention says quite a few U.S. adults do not engage in any leisure-time physical activity.

Even slim people who are inactive are at high risk of death and disease. So while reducing obesity is an important goal, “the better message would be to get everyone to walk 30 minutes a day” says Robert Sallis, co-director of sports medicine at Fontana Medical Center. “We find it necessary to refocus the national message on physical activity, which can have a bigger effect on health than losing weight.”

Regular exercise has been shown to prevent the ongoing damage done to cells, tissues and organs that underlies many chronic conditions. Building on that earlier research, scientific studies are now suggesting that exercise-induced changes in the body’s immune system may protect against some forms of cancer.

Researchers are also investigating whether exercise can influence aging in the body. In particular, they are looking at whether exercise lengthens telomeres, the strands of DNA at the tips of chromosomes. When telomeres get too short, cells can no longer divide and they become inactive, a process associated with aging, cancer and a higher risk of death.

A study, published in Circulation, the medical journal of the American Heart Association, concluded that physical activity has an anti-aging effect at the cellular level, suggesting exercise could prevent aging of the cardiovascular(心脑血管) system.

The guidelines, developed by the Department of Health and Human Services, recommend that adults get at least two hours and 30 minutes weekly of moderate-intensity aerobic(有氧的) physical activity, or one hour and 15 minutes a week of vigorous-intensity aerobic exercise, or an equivalent combination of both. The guidelines also say that additional health benefits can be obtained from as much as doubling the minimum recommendation for aerobic exercise.

1.What is the main purpose of many Americans who take exercise?

A. To have a good figure.　　 B. To make them strong-minded.

C. To cure some common diseases.　　 D. To prevent themselves getting old.

2.It can be inferred from the passage that __________.

A. natural killer cells strengthen the body’s immune system

B. regular exercise can remove the viruses and bacteria

C. obesity has become a social problem in America

D. American people need to attach more importance to physical exercise

3.How can physical activity stop aging?

A. By preventing cell division.　　 B. By getting rid of aging cells.

C. By making telomeres longer.　　 D. By repairing the damaged organs.

4.What might be the best title for the passage?

A. New Studies about Physical Exercise　　 B. The Hidden Benefits of Exercise

In New York City public schools, 176 different languages are spoken among the more than 1 million students. For 160,000 children, English is not their first language. New York's Department of Education makes learning better for these students by providing dual-language programs, in which students are taught in two languages, English and another one, like Russian or Chinese. Math, social studies, science and all other regular courses are taught in both languages. And they learn about the culture of the other country.

Milady Baez, Deputy Chancellor of English Language Learners and Student Support, says these dual-language programs will help children succeed in the future. "The jobs of the future require that our students know more than one language. They are going to be traveling abroad; they are going to be communicating with people from all over the world. This will open doors for them."

Middle-schoolers might not have jobs on their minds yet. For Kequing Jaing, she likes keeping up her first language, Mandarin."It makes me feel that I am home because I can speak in Chinese, learn in Chinese, while learning in English. So it makes me feel better and makes me understand more about the task I'm learning."

Anastasia Hudikova came to the United States when she was 2 years old. She says the Russian-English program keeps her connected to her heritage and her parents happy."They're really happy about the program. They are really happy that I can preserve my culture and my language, and that I can speak it fluently in school."

The New York schools also offer dual-language programs in seven other languages: Arabic, French, Haitian Creole, Hebrew, Korean, Polish and Spanish. There are plans to add even more languages in the future.

While these dual-language programs are popular, some organizations in the U.S. say teaching English comes first. U.S. Studies show that children who learn English early will be more successful later.

1.Dual-language programs in New York aim to __________.

A. help the students learn better

B. rid the students of homesickness

C. attract more international students

D.prevent the students forgetting their culture

2.Who may not quite agree with dual-language programs?

A. Milady Baez

B. Kequing Jaing

C. Anastasia Hudikova’s parents

D. some organizations in the U.S

3.The author writes the passage in order to_________.

A. encourage us to learn more languages

B. introduce dual-language programs in New York schools

C. advertise the dual-language programs

D. inspire more students to study in New York

Damage to Ozone Layer Gets Worse

In the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer．The warning: The sun's summertime rays are more dangerous than once thought.

A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone（臭氧层）in the atmosphere, which protects humans from harmful levels of ultraviolet（紫外线）radiation, will be thinner over the United States this summer．The thinner layer allows more ultraviolet rays from the sun to reach Earth．The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.

Scientists first became concerned about the layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter．The hole was caused in chemicals used in refrigerators and air conditioners．When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.

Concern about the protective ozone layer rose more recently when data from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica．Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.

Although many countries have already begun stopping the use of ozone-destroying chemicals, the new findings are expected to advance the timetable for a total ban of the chemicals.

1.The scientists have observed the ozone layer ______．

A．since 1980                     B．since last winter

C．for more than 20 years            D．for about one year

2.The ozone layer in the atmosphere can ______.

A．do a lot of good to human beings in many ways

B．protect humans from diseases caused by bad weather

C．do a lot of harm to human beings in the summer-time

D．protect humans from harmful levels of ultraviolet radiation

3.Scientists first found that there was a hole in the ozone layer ______.

A．above Arctic during the winter in the mid-1980s

B．above Antarctica during the winter in the mid-1980s

C．over somewhere in the north of the equator in 1980

D．over the USA in the summertime in the mid-1980s

4.The damage to the ozone layer was caused by ______.

A．the changeable weather          B．ozone-destroying chemicals

C．chemicals from refrigerators      D．chemicals from air conditioners

Students wishing to safeguard their careers against changes in the job market should opt for science rather than arts degrees, according to a survey of undergraduates.

Engineering and chemistry were considered to be the most “future proof”， as they are courses most likely to lead to an enduring and adaptable career.

Students polled by Pearson College were broadly optimistic that their chosen courses would prepare them for a world in which the job market could change dramatically during their working lives.

But opinion was sharply divided over which degrees were best for future­proof careers.

Eighty­two percent of respondents believed engineering would help develop future­proof skills, with 74 percent believing the same of chemistry and 73 percent of computer science.

But just 33 percent of undergraduates believed history would lead to a future­proof career, and 40 percent English.

However more than two thirds of students (67 percent) thought the world of work would be significantly different or completely unrecognizable in 20 years.

The findings, published today, come after Education Secretary Nicky Morgan sparked controversy with claims that teenagers should steer clear of the arts and humanities and opt for science or maths subjects if they want to access the widest range of jobs.

She said that in previous decades students would only take maths or science if they wanted to pursue a specific career such as medicine or pharmacy, but nowadays that “couldn't_be_further_from_the_truth”.

“If you wanted to do something different, or even if you didn't know what you wanted to do ... then the arts and humanities were what you chose. Because they were useful — we were told — for all kinds of jobs. Of course now we know that couldn't be further from the truth, and that the subjects that keep young people's options open and unlock doors to all sorts of careers are the STEM (science, technology, engineering and maths) subjects.”

She also described maths as “the subject that employers value most” and said that pupils who study A­level maths will earn 10 percent more over their lifetime.

“These figures show us that too many young people are making choices aged 15 which will hold them back for the rest of their lives.”she said.

1.In order to guarantee your future job, which kind of courses will you choose according to the survey?

A．Engineering or English.

B．History or Maths.

C．Maths or Art.

D．Engineering or Chemistry.

2.What's the students' attitude towards their chosen courses?

A．Doubtful.　　　　　 B．Worried.

C．Optimistic.　　　　 D．Objective.

3.How do you understand the underlined words?

A．It is far away from the truth.

B．It's to the truth.

C．It couldn't be closer to the truth.

D．It reflects the truth.

4.What did Nicky Morgan indicate in her claim?

A．If you want to do something different, the arts and humanities are what you choose now.

B．STEM subjects can make young people choose their future jobs freely.

C．At college, young people should make choices for their lives.

D．Maths and science are considered to be the subjects that employers value most.

People in the United States have many ways to get news, some of which are available 24 hours a day. In a recent survey（调查）, about 15 percent of American interviewees said that they spend less than one-half to two hours per day watching, listening to, or reading the news. News comes from every source, not only from printed ways, but from TV, radio, and the Internet as well.

With the increased availability of news, serious questions have been raised about the role of the news media in society. Should the media report every detail about every story, even when the information does not seem timely or valuable? Some researchers are concerned that by focusing on everything at once, the media increasingly ignore the more important social, political and economic problems that we face. We cannot concentrate on what’s important by reading about what is not. One extreme example of this is the type of information covered by the tabloid（小报）media, which focus on negative stories of violence and crime.

How can people deal with all the news that is available to them? Some become “news resisters” and choose to turn their backs on news, resisting their desire to turn on the TV and read the paper every day. They argue that although daily news reports may provide us with many facts, they do not include the background or some information that we need to understand news events. They suggest that, instead of daily reports, we look for information that has more in-depth analysis of the news, such as monthly magazines.

1.What percentage of the interviewees spend less than one half to two hours per day paying attention to the news? (within 3 words)

2.According to the researchers, what is the disadvantage of news media? (within 6 words)

3.How do you describe tabloid media? (within 5 words)

4.Who are “news resisters”? (within 9 words)

5.What information does “news resisters” look for? (within 2 words)
