Social networking isn’t only for the under 40s. More than 25 percent of Americans 50 years and older stay connected using sites such as Facebook, MySpace and Twitter, according to new research.

“The latest data tells us that more and more social networking is becoming a part of everyday life for Americans 50 plus,” said Kevin Donnellan, the chief communications officer at AARP, which released the report.

Nearly a quarter of older Americans are on Facebook and 73 percent said they use it to stay in touch with relatives, but not just their children and grandchildren. “They are using the Internet to keep up with the world and the people who are important to them,” said Jean Koppen, the author of the report. She added that older adults are also on Facebook to stay connected, not only with their family, but with their friends and those in the same age group. Almost 50 percent of older adults were introduced to the social networking sites by a family member, mainly a child or grandchild. “Just under one-fifth of adults aged 50 and older say they do not use the Internet,” according to the report.

The findings are based on a telephone survey of 1,863 adults. In addition to keeping up on Facebook and Twitter older adults are aware of the latest technology. Eighty-three percent had heard about the Apple iPad and 11 percent intended to buy one.

Despite the popularity of the Internet among the over 50s, they still mostly go to print newspapers and magazines for news. Only one percent said they followed blogs.

Scientists estimate that more than 60 percent of cancer deaths in the United States are preventable through lifestyle changes. Although there is no certain way to avoid all cancers, reducing individual risk factors greatly decreases the likelihood of getting many forms of this dangerous disease.

The American Chemical Society estimates that smoking causes nearly 30 percent of all cancer deaths in the United States — that is, about 166,000 cancer deaths each year. All cancer deaths caused by tobacco smoking could be prevented completely by not smoking and not using smokeless tobacco. For those who already smoke, quitting will reduce the risk of developing cancer. Studies show that after about ten years of not smoking, a past smoker’s risk lowers to about the level of those who have never smoked.

After quitting smoking, eating a healthy diet is the best way to lower the risk of cancer. Certain foods have been found to protect against cancer. Among these foods are cabbages, tomatoes, soy products, and foods high in vitamins A, C, and E. In addition, green and possibly black teas contain compounds that protect the body from cancer-causing substance.

To lower cancer risk, diets should include little or no red meat. Other foods to avoid or consume in moderation (适度地) include sugar, fat from animal products, and salt. Added fats and oils should come from vegetables, such as olives or corn, rather than from animal sources. Carbohydrates (碳水化合物) should come from whole grains, such as brown rice and whole wheat bread, rather than from processed foods, such as white rice and white bread.

The risk of cancer of the esophagus (食道) increases with heavy alcohol consumption, and many studies suggest that consuming alcoholic drinks increases the risk of breast cancer as well. Studies show that limiting intake to two drinks a day for men, and one drink per day for women, reduces cancer risk.

Low levels of physical activity have been implicated (牵连) in some cancer. Moderate activity for 30 minutes a day enhances the immune system, shortens the time food takes to move through the intestines (肠), and changes body composition and hormone levels. Researchers are studying how these effects might lower cancer risk.

1.Which of the following is true according to the author?

A. A person drinking tea regularly will not be likely to suffer from cancer.

B. Once a smoker has stopped smoking, there is almost no chance for cancers.

C. A balanced diet is absolutely effective in preventing one from getting cancer.

D. Those having quitted smoking for 10 years and non-smokers have less cancer risk.

2.What kind of people increase their chances of getting cancers?

A. Those whose foods contain less sugar, animal fat, and salt.

B. Those who are not moderate in drinking, smoking or eating.

C. Those who have only one or two drinks regularly per day.

D. Those whose diet contains little red meat and a lot of vegetables.

3.Which do you think is the best title for this passage?

A. The relation between food and disease.    B. Causes of different kinds cancers.

C. Tips on lifestyle for cancer prevention. D. Ways to remain more healthy.

4.We can infer from the last paragraph that _______.

A. food’s staying in body too long might have something to do with cancer

B. the reasons why physical activity lowers cancer risk are clear

C. the more you exercise, the lower cancer risk you will take

D. plenty of physical exercise is most important for remaining healthy

According to the WHO, 90 percent of the world’s population lives in a place where they are exposed to unsafe levels of airborne pollutants, contributing to up to seven million deaths each year. If you live in a city, chances are that you’re part of that 90 percent, even if your city is relatively clean. That’s why cities worldwide have started embracing Internet of Things (IoT)solutions.

One of the best ways to fight pollution is to figure out where it’s worst and where it’s coming from. If you’ve ever made a habit of checking air quality around you, you may notice that there aren’t actually that many monitoring stations, and your closest one may not be that close. For pollution data to really be accurate and helpful, we need a lot more of it.

Luckily, IoT sensors and low-power wide-area networks are making it a lot easier to get and spread ultra-local data. Lampposts are one popular place to put them. For example, the Republic of Korea and Barcelona have already built out a network of pollution sensors in their streetlights. On the other hand, outfitting (配备) cars, bikes, and even people with pollution sensors provides valuable data on a smaller, more mobile scale.

Since pollutant levels can change dramatically even from one city block to another, having smaller-scale data is important for making a lot of decisions that, over time, might have a major influence on our health and behavior. It can influence where we decide to live, when we exercise, whether we bike to work, and, perhaps most importantly, what we can do about pollution in our area.

What all the Internet of Things can help us do on a personal level is use less energy. The data it provides, though, can be used to make big and small changes to the way we behave and build, and that is eventually where we’ll see benefits.

1.What’s the problem mentioned in Paragraph 1?

A.The death rate is high every year. B.There are too many people in the world.

C.There is little space for people to live in. D.Air pollution is more serious than expected.

2.How does the author mainly develop Paragraph 3?

A.By analyzing main causes. B.By citing research findings.

C.By giving specific examples. D.By making close comparisons.

3.Why is it necessary to collect data on a smaller scale?

A.It directly decreases pollutant levels. B.It uses less energy to clean the air.

C.It covers more areas of air pollution. D.It betters decisions on our lifestyle.

4.What’s the author’s attitude towards using IoT to solve air pollution?

A.Disapproving. B.Doubtful.

C.Positive. D.Uncaring.
