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?

As is known to all that millions of graduates crowded into the job market each year. But because the financial crisis, the situation of the employment has become very serious. Consider this, some people suggest graduates should have a lower career expectation, such as working in the western area of China. I in favor of this idea. Firstly, compared with the big cities, the competition is not as fierce there, but graduates can easy get a job. Secondly, the lower position may offer graduate more space. All in all, going to the west may be bring more benefits. Devote yourself to the west, for it is both good for our personal development and for our country at present.

EVERY YEAR, millions of Americans see their personal information leak into the wrong hands. Maybe there’s spyware on their computer, or a service they use suffered a security reach --- as eBay did this year, leaving customers at risk of exposure. Or perhaps their password is easy to guess: Security company SplashData reports that the most popular passwords in 2013 were 123456 and password.
Fear not: It is a lot easier than you might think to set up proper defenses. In fact, you can easily do it all in a weekend. Here’s how.
Clean Your Computer And Smartphone
Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy- or malware that may have already infected your system. Go with AVG Free Antivirus (free. Avg. com) or Avast! (avast. com) ---each is free. Run a full system scan. This can take over an hour, so start it before settling into other plans. When you return to your computer, clear out anything that shouldn’t be there with a few simple steps (the program will guide you). These days, it’s also worth it to make sure your phone is safe from viruses. iPhones are less likely to be targeted by spyware, but Android users should download the Lookout app (lookout. com) to scan their devices and ensure everything is as it should be.
Security Your Wi-Fi
Now that your computer is clean, you should plug any holes in your home network. It’s fairly easy for potential criminals to gain access to your information if they’re able to share your connection --- that’s why you want to be careful when using public Wi-Fi. For your home, the Federal Communications Commission recommends a few steps. Even though you put security measures into place a couple of years ago, it’s a good idea to refresh your settings. You may have to refer to the instructions for your wireless router or call tech support for help. Different routers will have different setup pages, so the actual step-by-step will vary, but the end result will be the same.
Dig Deep with Your Passwords
Everything you just accomplished could be for nothing if a thief has your existing passwords, so you need to change them for every service you use. Try it when you find yourself on those sites anyway.
What you’ve heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. They should be close to random, and there should be a different one for each website you use. Doing this, and keeping track of it all, is a pain --- which is why people don’t do it and wind up with stolen identities. Try Dashlane (dashlane.com), a password manager with powerful encryption (加密) that can securely keep track of the most ridiculous codes you can come up with. Best of all, it logs you into sites automatically, so there’s no need to worry about all those obscure keystrokes. Whew!
Never Answer Unwanted Email
Take are when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption is not there, do not give out credit details. Also, check that the site is legal --- never go to a site from a random email and start shopping online. Go to the site through a known URL or by searching for it on a search engine first.
Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for “in real life” can still be used uninfluenced.
Don’t store information on any store’s website. It may be conventional but it’s also a possible loss to you if the site is hacked.
1.The passage is mainly about _____________.
A. ways of avoiding online identity theft
B. tips of freeing computers from viruses
C. measures to ensure network security
D. steps to keep track of passwords
2.According to the passage, the risk of exposing personal information may possibly be caused by ___________.
A. the applications of antivirus programs
B. the practice of using public Wi-Fi
C. the difficult access to the passwords
D. the separate credit card for online shopping
3.To put new security measures into place, we need to ____________.
A. clear out of everything in the system
B. make a random selection of network
C. get rid of potential spyware
D. refresh the infected system
4.Which of the following is the improper way to shop online?
A. Adopting a unique password for every website.
B. Shopping online at reliable websites.
C. Keeping credit details safe by checking security symbols.
D. Monitoring credit card by storing information.

New rules will let millions of Americans know where more of their food comes from. The law is known as COOL -- Country of Origin Labeling(标签).
American congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are not included. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked foods.
The same food may sometimes have to be labeled and other times not. Fresh or frozen peas, for example, have to be labeled but not canned peas. Foods that are mixed with other foods are also excluded. Mixed nuts, for example, do not need to be labeled. The same is true of a salad mix that contains different things like lettuce and carrots. Or a fruit cup that combines different fruits. Also, the law doesn’t include restaurants and other food service organizations. Department of Agriculture officials say the law is really meant for larger grocery stores.
The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods came from. For example, when a large number of people recently got sick from salmonella(沙门菌病), officials blamed peppers from Mexico. Yet the last big food scare involved spinach grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations(违反) that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1,000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information.
1.Why has more and more food been imported to the United States in recent years?
A. It is economical and provides people with more choices.
B. Foreign food is of higher quality than native food.
C. Americans need more and more food recently.
D. The United States is short of food supply.
2.Consumers are more concerned about where foods come from because________.
A. they are curious about the origin of the food.
B. most of them are particular about the tastes
C. they are concerned about food safety
D. most of them are food safety activists
3.The new rules of the country-of-origin labeling law will come into effect________.
A. right now B. in a month C. in three months D. in half a year
4.Which of the following can be inferred from the text?
A. Store owners are most likely to be the supporters of the law.
B. The government of America will possibly forbid importing peppers from Mexico.
C. Federal inspectors couldn’t take measures to enforce the law.
D. Most Americans prefer imported vegetables to the vegetables grown in local places.
