There are many kinds of food in the world. Scientists know a lot about it. They say that there are some kinds of food people must eat every day. For example, people must eat some green and yellow vegetables. We shouldn’t eat too much meat. People also need to eat some fruits, bread and rice. Of course our bodies need some water and milk.
Scientists say people in different countries and different places eat different kinds of food. They cook food in different ways. Different people eat at different times. In one place, people eat once or twice a day. But in another place, people eat three or four times. Scientists say when to eat and how many times to eat are not important. What we eat is the most important thing.
Nowadays, the world faces two problems. People in some places, for example, in Africa, are not full. Many people are eating junk food. It’s bad for people’s health. So it’s our duty to make everyone full and make everyone healthy.

【推荐2】A smart diet，a healthy life
No matter how old your kids are，you can take steps to improve a healthy diet and to encourage good eating habits. Here are some tips.
Family meals
Family meals are nice for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children. Parents can also use the mealtime as a chance to talk with their kids about their life.
Healthy snacks(零食)
Kids，especially younger ones，will eat mostly what they can get at home. That's why it's important to have enough healthy snacks，such as fruits，vegetables，nuts，yogurt and whole grain biscuits.
Being a good example
The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the adults they see every day. By eating fruits and vegetables and avoiding(避免) fast food and sweet drinks，you are sending the right message．
No shouts about food
Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat. You need to work a bit on different cooking methods(方式，方法)．

【推荐3】Wu Yue, a 14-year-old student at a Junior High School in Hangzhou, usually has lunch with his classmates in their dining hall. But one day, a newcomer, the school headmaster, joined them at the same table. They talked about the food that the dining hall offered and had a nice chat.
Wu is not alone. Many students across China have the chance to eat with their headmasters. The government issued a notice on food safety and nutrition (营养) management in schools, asking headmasters from kindergarten to high school to have meals with students. The rule took effect (生效) on April 1st.
Many schools now have seats for school managers when they eat with students in the dining hall. After talking with them, the managers have to write reports and make suggestions to dining hall workers. Many students were asked about the food that they liked most. To their surprise, their favorite dishes appeared in the dining hall later, “It’s not just about the food. It makes me feel that I have a say in school,” explained one student. “My ideas are valued.”
Some headmasters regard these mealtime conversations as their main chance to communicate with students. And they notice that some students prefer meat to vegetables. “We are thinking about how to improve the dining hall’s dishes and provide students with a healthy diet,” one headmaster said. As students become more familiar with the school managers, they begin to express their own points of view.
“It’s important to understand students’ requirements. Our practice shows the school’s sense of responsibility,” another headmaster said.

【推荐1】Working from home is more and more popular as a means of escaping the nine-to-five office life. Why do you work under the eye of your boss when you can work in front of the TV in your slippers? Armed with all the necessary things—telephone, computer, e-mail and fax, many workers believe they can work as effectively as their colleagues in the office. Being able to work wherever you like: from a busy city to a village, and not having to stand the daily things, make working from home an attractive choice. If you wish, you can even work on a river boat.
So what will become of the office tomorrow? It is possible that many could go into computer space creating a new wave of virtual (虚拟的) offices. To minimize office in inner-city areas, companies will have a work force made up of a network of home, workers linked by an advanced communication and information system. A central processing computer would be controlled by the manager who sends out work schedules and oversees (监视) the activity of each employee.
A video screen would be created, as the need for e-mail or telephone becomes greater. Seeing the mood and expression of work colleagues, mangers would have the ability to view several employees at once on their screen. Employers would be encouraged to feed any information that may be useful to fellow workers into the computer to make the company work more effectively. As the company’s lifeblood, the computer would contain a record of all conversations and communication for future reference and hold secret information such as accounts in password (口令) protected areas.

【推荐2】Electric vehicles have been around for more than a hundred years. But they have really been liked by a large number of people over the last ten years. More than three million all—electric cars, trucks and vans are now on the road worldwide.
Helping the Environment
Most cars run on gasoline. Burning gasoline and other fossil fuels produces greenhouse gases. Electric vehicles don’t burn gasoline. Instead, strong batteries run their electric engines. So, electric vehicles don’t directly produce greenhouse gases.
Poop Power!
Electric vehicles are better for the environment. But they are not perfect. Their batteries often use electricity that was made by burning fossil fuels. But an electric vehicle uses less energy than a vehicle that runs on gasoline. Plus, some of the electricity comes from “greener” sources, such as solar and wind power. And some may soon come from a new source — cow poop! An electric car company has worked together with a large dairy farm. They plan to make electricity using a greenhouse gas from cow poop.
Always Improving
One of the problems for electric vehicles is their limited range. This is how far they can travel before their batteries need another charge. But now their range is improving. Some new electric vehicles can travel almost three times as far as older ones did. Another problem is finding a place to recharge the batteries. But the number of charging stations is going up as well. China now has thousands more charging stations than it did ten years ago. In Sweden, engineers have even designed a road that will charge electric vehicles as they drive along.

Cats love mirrors — they often either look at them curiously or try to touch “the other cat” with their fluffy paws. But do they actually recognize themselves in the mirror? And how can we learn the answer when we have no way of knowing what animals are thinking. Back in 1970, Gordon Gallup, a scientist from the State University of New York, developed a test called the “mirror self-awareness test”, according to Science Daily. His team of researchers painted a red dot on the animal’s forehead — which the animal could only see by looking into the mirror — and watched its reaction to the dot.
In the test, some cats ignored their reflections and just went away. Some attempted to look behind the mirror. Some even acted aggressively toward the mirror. All of these behaviors show that cats think of their reflections as separate cats instead of as themselves.
However, when chimpanzees saw the dots on their foreheads in the mirror, they first attempted to make direct contact with the reflections, then looked behind the mirror and finally touched their own foreheads. This means the chimps realize that the dots are on their own bodies. That suggests self-awareness.
It's just like when you look into the mirror and see something on your face — you touch your own face to brush it off instead of reaching for the image in the mirror.
Very few animals pass this test and cats certainly don’t. Besides chimpanzees, other animals that seem to have a sense of self include gorillas, dolphins and elephants. However, the mirror test has received plenty of criticism. People say that although it proves that certain animals are self-aware, it can't be used to prove that other animals are not. They say that it's unfair to the animals that rely more on senses other than sight, such as cats and dogs.
It's also possible that by not touching the spot, the cat is simply showing that it doesn’t care about cleaning it.
