American farmers are raising five percent more goats for meat these days．

Goat meat is high in protein(蛋白质)and lower in unhealthy fat than many other meats．Even so，the industry is small compared to chicken，beef and pork. But immigration has brought more of a taste for goat to America from all over the world.

Experts from the University of Illinois offer some questions for people to consider if they are thinking about raising goats．

First of all，do you understand that there always has to be someone to care for the goats?

◆How much land do you have available? And how good is it? Poor ground may support two to four goats on half a hectare．Better grassland can support six to eight. If goats and cattle share the land，two goats can be added for each cow. The goats will eat weeds and other plants that cattle do not like．

◆Do you have buildings for the number of female goats you plan to keep during winter? An open，cold，dry barn is better than a closed，warm barn where the air is wet．

◆Do you have the equipment to clean barns（畜棚） and to harvest hay（草料） to feed your goats? Or will you get someone else to do it，or buy the hay?

The experts say a profitable business in goat meat may take three to five years to establish．And, of course, there are no guarantees .

On which section of a newspaper will this passage appear?

A．International Affairs B．Entertainment

C．Agriculture D．Culture

Which of the following is NOT a factor in making goat meat more popular?

A．Goat meat is healthy food.

B．Immigrants bring different tastes.

A．32 cows and 64 goats． B．32 cows and 32 goats．

C．16 cows and 32 goats． D．8 cows and 16 goats．

What is the experts’ opinion about the goat-raising business?

C．Goats are hardly possible to raise．

D．Goat meat still needs to be recognized．

I’m talking about the gift of fitness. Improved fitness is a gift that is invaluable to everyone. When you give a woman the gift of fitness, you are helping her open a door to better health.

All Moms would find these fitness benefits extremely invaluable. If they are like most of us, they have probably even mentioned how they would like to drop a few pounds or just get in better shape. In fact, experts say that about 62% of Americans are currently on a diet. By giving the gift of fitness you are helping provide your mom with extra motivation.

With only a click of the mouse, rumors can be forwarded between microblogs very quickly. As an example, recently, perceptive netizens discovered that some photos displayed on microblogs depicting Beijing’s June rainstorm had actually been fabricated.

Sina.com is one of the major internet portals(门户网站) in China with hundreds and thousands of users, and a majority of celebrities and renowned citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to verify rumors and provide accurate information for its users. Tan Chao is in charge of the team.

“Before I took the job, I usually couldn’t identify what information was real and what was fake. But during the rumor verification process, we discovered that a lot of information was false, including fake photos, fake news stories and rumors that had been spread through microblogs.”

It‘s not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumor Verification Federation on Sina.com’s microblog system to help netizens identify fake information online.

　　Dianzizheng is the team leader of the federation. He says they’ve publicized more than 150 pieces which refute rumors, which attracted more than 10 thousand visitors within two months.

　　“We live in an age of new media, so we can’t use the old methods to verify rumors. We can’t wait for the media to verify the facts with related administrative departments and then release a formal announcement. We can’t allow rumors to run rampant and then deal with it, we need to fight rumors while they’re spreading. I think that this is the best way to deal with rumors nowadays.”

　　Some experts say this demonstrates the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wenguo, President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the internet is still quite limited.

　　“It’s still quite difficult to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is deluged with too much false information, and it’s allowed to spread in such a fast manner, then people will be suspicious of all kinds of information including important information from authorities. It also exacerbates(恶化) problems relating to social communications and mutual-understanding, which in turn harms society as a whole.”

　　Experts suggest that the government should react more quickly in the internet age. Once a rumor begins to spread, administrative departments should make announcements as early as possible to dispel rumors before they lead to bad outcomes.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.

Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.

The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr.Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on -one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.

If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.

Sports can help you keep fit and get in touch with nature．However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry．Golf, as you may know, eats up not only large areas of countryside, but also tons of water．Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition．This causes major environmental effects．For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas．

There are many environment-friendly sports．Power walking is one of them that you could take up today．You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse．Simple and free, power walking can also keep you fit．If you walk regularly, it will be good for your heart and bones．Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials．But the final goal should be “green gyms”．They are better replacements for traditional health clubs and modern sports centers．Members of green gyms play sports outdoors, in the countryside or other open spaces．There is no special requirement for you to start your membership．And best of all, it’s free.
