Sweet potatoes are fat-free, high in fiber and full of the vitamins that research suggests reduce your risk of life-shortening diseases. To stay healthy, we must eat more fruits and vegetables, and sweet potatoes are a great source of beta carotene(胡萝卜素) and other carotenoids(which the body turns into vitamin A). According to a study of the diets of almost 90,000 nurses, eating about one cup a day of fruits and vegetables rich in carotenoids can cut your risk of stroke in half and reduce your risk of heart disease by 22 percent. Other research suggests beta carotene protects against breast, lung and stomach cancers.
Beta carotene is the most famous member of the carotenoids family. In face, a medium-sized sweet potato contains nearly 12mg of beta carotene(anti-aging experts usually suggest 6 to 11 mg per day). Sweet potatoes are also a low-fat source of vitamin E. Research has linked high E diets with a lower risk of heart disease. This vitamin pill in an orange jacket also packs a vitamin C punchit which has more C than apricots (a kind of fruit). Research suggests that vitamin C protects against ailments (小疾) ranging from cataracts(an eye disease) to cancer. In addition, a UCLA (University of California Los Angeles) study linked high vitamin C diets with a longer life. Recent studies have showed that antioxidant Vitamins C, E and beta carotene fight a fierce battle against free radicals (自由基），which cause cell damage and lead to various illness. Therefore, to keep fit, eat more sweet potatoes.

Making group purchases of famous local products and cosmetics (化妆品) with co-workers has become a common habit for the nine-to-fivers. But if your impression of group buys is still a piece of paper being passed around the office, everyone writes their details down, or endless phone calls or faxes to the supplier, then I’m sorry to say you’re behind the times. The popular way to make such purchases today is to get on line, form a special “group” and shop together. Not only can you save money by getting the best discounts, but it’s also a great way to meet new people.
“You could cut off my clicking finger and I’d still keep shopping this way!” so goes a common comment left by customers of China’s famous e-commerce website “Taobao”. Some even refer to group purchasing as a “path of no return”, saying that “Once you’ve tried it, you’ll get hooked!”
The origins of this new trend can be found in China’s well-known online consumers’ BBS, 55BBS, and the shopping boards. Since most BBS users are “white-collared workers and students who live in concentrated areas, buying clothes, food, and so on as a group saves on delivery costs as well as – if they meet the seller’s criteria (标准) – earn gifts, discounts, and frequent shopper points.
Users of this online group shopping boards purchase a lot of different items, from Japanese and Korean style clothes and Ugg boots, through fake eyelashes (假睫毛), stockings, food seasonings (调味品), and kitchen knives, to cosmetic masks and online college courses. All kinds of things have people coming together in groups to buy them, and the pickups are often organized on college campuses or office buildings.
Internet observer Liu Chenxi points the purchasing behavior that these online groups’ power creates a “team” effect. Unlike e-commerce sites driven by individuals’ purchases, sites that create this team effect have users that come together to achieve a common goal. The Internet has made this joining of forces to form group buying power possible, and it continues to snowball all around us.

Modern scientists have mad great development in building computers that can imitate logical thought. There are two schools of thought on artificial intelligence(人工智能)。 Supporters of “Strong AI” consider that all human thought can be broken down into a set of mathematical operations. They expect that they will one day be able to copy the human mind and create a robot able to both think and feel, with a sense of self---the stuff of classic science fiction. Supporters of “Weak AI” think a computer might seem intelligent, but it is not aware of what it is doing, with no sense of self or consciousness.
Now the development of life---like robots may be closer to reality than you think. Engineers have created robotic soccer players, and bees that act like the real thing.
Powered by a small battery on her back, humanoid robot Lola is a soccer champion. “The idea of the robot is that it can walk and see things because it has a video camera on top.” Raul Rojas, Ph.D., professor of artificial intelligence at Freie University in Berlin, Germany, told Ivanhoe. Using the camera on her head, Lola recognizes objects by color.
“Using this camera, Lola can locate objects on the floor, such as a red ball, go after the ball and try to score a goal,” said Dr. Rojas. German engineers have also created a bee robot. It can imitate the bee’s
“waggle” dance which communicates the location of food and water.
“Later what we want to prove is that the robot can send the bees in any decided direction using the waggle dance,” said Dr. Rojas.
Robots like this could one day become high-tech surveillance(侦察) tools that secretly fly and record data.

C. Engineers have created robotic soccer players and bees that can replace the real thing,
D. Scientists have made great development in recording data in the past few years.
THE Little Mermaid, a fairy tale by Danish author Hans Christian Andersen is well known. It tells of a young mermaid who falls in love with a prince. She wants to be with the prince so she gives her tongue to a witch, who gives her legs for her fish tail. But the story has an unhappy ending. The little mermaid never gets to be with the prince.
At the Denmark Pavilion(展馆)at Shanghai Expo 2010, visitors will have a chance to meet the little mermaid. How so? In the form of the famous statue from Copenhagen.
Petersen Niels Lund Petersen, a designer of the pavilion said the idea was to find something for the Chinese and the Danish to share.
The brewer（酿酒商）Carl Jacobsen of Carlsberg gave the statue to the city of Copenhagen in 1913. The work of Edvard Erichsen, the statue, is one of the most well-loved in Denmark. About 75 percent of all tourists who visit the Danish capital go to see the Little Mermaid.
Visitors to the pavilion will find the Little Mermaid in the water from Copenhagen’s harbor---just as she is in her home city.
Two decades ago the harbor was filthy with pollution from factories. Today it is so clean that local people will sometimes take a swim in it. Visitors to the pavilion will be able to take off their socks and shoes and dip their toes in the water.
The pavilion will give visitors a sense of life in a modern Danish city. They can ride a bicycle in a Danish bicycle path, visit a park on the roof and have an organic picnic there, China Daily reports.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food ,get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little a amount of sleep may even result in a change of personality (人的个性).Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

There is a popular belief among parents that schools are no longer interested in spelling. No school I have taught in has ignored spelling or considered it unimportant as a basic skill. There are, however, vastly different ideas about how to teach it, or how much priority(优先) it must be given over general language development and writing ability. The problem is, how to encourage a child to express himself freely and confidently in writing without holding him back with the complexities of spelling.
If spelling becomes the only focal point of his teacher’s interest, clearly a bright child will be likely to “play safe”. He will tend to write only words within his spelling range, choosing to avoid adventurous language. That’s why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about personal experience: “This work is terrible! There are far too many spelling errors and your writing is illegible(难以辨认)”. It may have been a sharp criticism of the pupil’s technical abilities in writing, but it was also a sad reflection on the teacher who had omitted to read the essay, which contained some beautiful expressions of the child’s deep feelings. The teacher was not wrong to draw attention to the errors, but if his priorities had centred on the child’s ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.
