Here are five best things that will help keep your pearly teeth shiny.
Apples
Though apples technically have sugar, they’re not quite in the same type as a candy. Apples are high in fiber(纤维) and water, which are both key parts in removing food remains from your teeth. The biggest advantage, however, is the quality of the apple, and the fact that you have to bite so much to break it down enough to eat. And that act of biting produces saliva(唾液) that can help to protect your teeth from sugar and other harmful things that often cause tooth problems.
Cheese
Cheese, along with other milk products have bacterium that have been found to raise the PH levels inside your mouth, and in turn, lowering their risk of tooth problems. Cheese also has calcium (钙)and protein that help strengthen teeth.
Leafy Greens
It’s true that leafy greens like cabbages and many more will likely find their way on any lists of healthy foods. This is because they are full of healthy vitamins and minerals while being low in calories. Specifically for teeth, however, these green vegetables are high in calcium to help build good enamel(釉质).
Almonds (杏仁)
Almonds are fantastic for your teeth because they contain calcium, protein, and like the leafy greens, they are also low in sugar. They also require quite a bit of biting to break down, adding to the production of that all-important saliva.
Water
Water contains fluoride(氟化物)that is a mineral which has been known because of its teeth strengthening powers. And when there is plenty of fluoride in your drinking water, it can do a wonderful job like that.
So if you want to own healthy and shiny teeth, keep having them often.

Four ways to have a good school life
Your schooldays should be some of the best and happiest days of your life. How can you get the most from them, and be sure you do not waste (浪费) this great chance to learn?
Be active(积极的) at school Don’t say things are difficult or boring. Take interest in school life and your school subjects. Join lots of activities. Put up your hands quickly in class. Go around the school with a big smile. If you are not working, you are wasting your time at school. Teachers cannot make everything enjoyable(令人愉快的).
Keep fit If you don’t eat a good breakfast, you will be thinking about food in class. If you go to bed late and don’t have enough sleep, you will be sleepy in class. Play enough sports every day in order to keep your body strong.
Face the problem Do not say you will do things tomorrow. If you get behind the class, it is very difficult to get back in front. You cannot finish the race if you rest all the time. Everyone fails some exams, loses some matches and has bad days. Don’t make small problems very big and important. Don’t forget to ask for help. You are young, and no one thinks you must do everything quite well!
Spend the weekends Don’t waste time lying in bed on Saturday or Sunday morning. Go and play sports, get together with friends in the park to relax, learn to play the piano, or help someone with problem. If you don’t want to go out, there are also a lot of things to do. You may read a book, practice English
or help Mum with housework.
Follow our advice, and have a happy school life!

Literature is a word used to describe written as well as spoken material. Generally speaking, it is often used to describe anything from creative imagination, including works of poetry, drama and fiction.
Then why read literature, since it is often imaginary and seems unconnected with real life?
A lot of us read literature for enjoyment and relaxation. It’s always pleasant to read some interesting books in our spare time. In a modern life full of stress, it is our common wish to read some imaginary works and look for relaxation from the stress in life.
Reading literature is more than fun; it also allows us to get knowledge. As a general rule, literature represents a language of a people, and it often gives us an insight(洞察力) into the traditions, attitudes and values of the age in which it was written.
Sometimes literature can even offer us new, creative ways to have a better understanding of the world. It introduces us to new worlds of experiences. We enjoy the comedy and the tragedy of poems, stories and plays; and we may even grow through our literary journey with books. At last we may discover meaning in literature by looking at what the writer says and how he or she says it. In some ways, we explore the human condition and analyze(分析) the way they think and feel the way they feel. Literature helps us think clearly and encourages us to open minds.
So we can certainly say literature is of great importance to us. Why not get going with one poem, drama or fiction at once?

Humans share Earth with many different kinds of wildlife.
However, many of our animal friends may not be around for much longer. According to the Living Planet Report released by the World Wildlife Fund (WWF) in October, there has been 60 percent in the populations of animals including mammals, birds, and fish since 1970.
“If there was a 60 percent decline (下降) in the human population, that would be equivalent (等于) to emptying North America, South Amcrica, Africa, Europe, China, and Oceania.” Mike Barrelt, director of science at WWF, told the Guardian.
According to the report, one of the biggest causes of wildlife losses is human activity. Three-quarters of the world’s land is largely influenced by human activity. Many natural habitats (栖息地) have been destroyed to create farmland.
About 300 kinds of mammals are dying out because we eat them. Another example is the industrial overfishing of the oceans, the Guardian noted.
These developments lead scientists to believe that there could be a sixth mass extinction (大灭绝), the first to be caused by humans, according to the Guardian. There have been five mass extinctions before, the last being 65 million years ago. That time it was the dinosaurs that died out.
WWF has called on world governments and businesses to make a deal to protect people and nature. According to a report by China Daily in November, Chinese paddle-fish in the Yangtze River, may have become extinct. And there are now less than 500 green peafowls (孔雀) in the wild, reported CCTV in June.
To protect endangered animals, China has stopped the use of rhino horn (犀牛角) and tiger bones, and ivory trade, reported China Daily. It also increases public attention by holding activities when celebrating the World Wildlife Day.
But more efforts are still needed to protect wildlife in China and around the world. “We are the first generation to know we are destroying our planet and the last one that can do anything about it,” WWF UK Chief Executive Tanya Steele told CNN.
