What is the strongest part of your body? Your head? Bones? It’s your teeth! There is a special thing called enamel (牙釉质) in teeth. It is the hardest thing in the human body and keeps bacteria (细菌) away. However, teeth are vulnerable (易受伤害的) to problems and disease. September 20 is National Teeth-loving Day in China. Let’s pay attention to the health of our teeth.
Tooth (1) are (1) around the world. Most children and young adults have tooth decay (龋齿). A study published on China Health Monthly magazine this year showed that 40.74 percent of a sample (抽样) of 1,306 Chinese students under age 15 had decayed teeth.
(2)Food that is rich in sugar increases the risk of tooth decay. After you eat, bacteria go crazy over the sugar on your teeth, like ants at a picnic. The bacteria turn sugar into acids (酸) that eat away at tooth enamel.This cause holes in your teeth.
Another common problem is crooked teeth (龅牙). When your new teeth begin to grow and the old teeth haven’t fallen out, there isn’t enough space for the new ones. This causes crooked teeth.
Don’t worry. Here are some ways to keep your teeth healthy.
Brush at least twice a day – in the morning and before bedtime.
Learn to use dental floss (牙线). The floss gets rid of food that’s hidden where your toothbrush can’t get it.
Visit a dentist. He or she can check if you have any dental problems and help you clean your teeth.
Pay attention to what you eat. It is better to eat lots of fruits and vegetables instead of fries and drink water instead of soda.
Wear braces (牙套) to make your teeth straight and beautiful.

You know that eating a suitable diet and getting plenty of exercise help make your body healthy and strong. But did you know that there are ways to make your brain healthier and smarter?
Studies show that when the brains is forced to do something new, it creates new neural (神经元) pathways. The more pathways you have, the faster you can think and the better memory you will have. Wonderful steps towards a smarter brain are as follows:
Choose proper TV programs
Watching an average TV show needs very little brain power and brings the same result as giving no care to physical exercise. Your brain will become weak just as your muscles do,if you watch TV, choose something educational and full of information.
Travel
Traveling to a new country forces you to see and do things in a new way, making your brains more active.
Learning a new language
A new language learner usually uses different learning methods. Learning a language sharpens your brain and helps you prevent memory problems in later years.
Master a new subject
Each week, choose an animal, a bird or a fish, and read everything you can about it. Go on learning unitl you become an expert on the subject.
Use your non-dominant hand
If you are right-handed,use your left hand for everyday activities, or use your right hand if you are left-handed. Doing familiar things in a new way will cause your brain to create new neural networks.
Read often
As you read, take the time to look up people or places that aren’t familiar. Reading can enlarge your vocabulary if you search for words and expressions that you don’t know.
Calculate while you shop
As you put things in your shopping bag, total everything in your head. See how close you get to the actual total.
Play video games
Studies have found that some video games force you to use critical decision-making skills and can even improve students’ math grades.
So get into the habit of challenging your brain, and make yourself smarter!

Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college.

Are you in a bad mood? Don’t worry! According to a new Australian study, a bad mood can actually be good for you. The study showed that being sad could help people to judge others more correctly and was also good for the memory.
The study was carried out by Professor Joseph Forgas at the University of New South Wales.“People in a bad mood paid more attention to the people and things around them than happy people .Happy people were more likely to believe anything they were told,”said Forgas

At present, more and more people are crazy about travelling. Why do people travel? “To see more of the world.” many people would say. But travelling abroad now means much more than that for the growing number of Chinese tourists. Of course it offers us good opportunities to meet people from other countries, learn about their culture and customs.
According to the United Nations World Tourism Organization (UNWTO), more than 1 billion people travelled to another country in 2012. In 2012, Chinese people travelled abroad 30 percent more than in 2011. The prosperity (繁荣) of the tourism industry can also bring both our country and foreign countries great economic benefits (经济利益). Chinese people usually travel abroad in large tourist groups and visit several countries in one trip.
Chinese people don’t just travel for sightseeing. The China International Travel Service Company said that all their tour trips sold out a month before Christmas Day. Stores offered discounts (打折) during that time, so shopping in Europe and the United States is popular among Chinese travelers.
In December, China is going through a very cold winter. So many people like to go to some countries in Southeast Asia because the weather there is quite pleasant.
The improvement of living standards means more Chinese can travel abroad. But many of them don’t have a sense of public manners. A report by Living Social website in March 2012 even listed Chinese as the world’s second worst tourists.
If you want to change that bad name, remember to avoid the following: littering, spitting, snatching bus seats, line-jumping, taking off shoes in public, talking loudly and smoking in non-smoking areas. Besides, we should learn some necessary manners of foreign countries.
【小题1】What are more and more people crazy about at present?
【小题2】How many people traveled to another country in 2012?
【小题3】Where is shopping popular among Chinese travelers?
【小题4】Why do people like to go to some countries in Southeast Asia in winter?

How green are you? Do you know how to be green?
We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.
Reduce
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup of a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
So please remember these three words: reduce, reuse and recycle.
【小题1】What is the passage about?
| A．How to produce things. | B．How to burn things. |
| C．How to help others. | D．How to be green. |
| A．Don’t waste things. | B．Always throw away old things. |
| C．Always buy new things. | D．Buy too many things from abroad. |
| A．You can burn them. |
| B．You can use them again. |
| C．You can throw them away. |
| D．You can change them into something else. |
| A．waste, reuse and recycle | B．repair, burn and recycle |
| C．reduce, reuse and recycle | D．reduce, waste and recycle. |
| A．a menu | B．a dictionary | C．a storybook | D．a magazine |

Lending a hand There are often elderly people living in the neighborhood who may not be able to do the things that you can. Offer to do iheir shopping once a week, look after their garden for them or maybe walk their dog.
No littering Nobody likes picking up other people's rubbish, but a clean street can make all the difference. Take it in turns to go out once or twice a week and see what you can find. You never know, one day you might find something valuable.
Recycling Nearly two-thirds of your rubbish can be recycled. Some areas already provide places to people to recycle bottles, tins, plastic and paper. Find out if this is done in your neighborhood. Ifit's not, do something about it.
