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.
Teeth problems are common 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.
(1)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 ______ ______(2) 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): it can make your teeth straight and beautiful.

Are you a gourmand(美食主义者)? Do you want to eat every delicious food in the world? Then do you watch the popular program? “A Bite of China(舌尖上的中国)” is a documentary on Chinese delicious food which has been broadcasted by Chinese central television. Is there any holiday that isn't celebrated with a special festival food? Here are several traditional Chinese foods:
Eggs hold a special meaning in many cultures, and China is no exception(例外). The Chinese believe eggs mean producing something new. After a baby is born, parents may hold a "red egg and ginger party," where they pass out eggs to announce the birth. In some areas of China the number of eggs represents the sex of the child, for example, an even number(1,3,5,---) for a girl, and an odd number(2,4,6---) if a boy has been born.
Noodles are a symbol of longlife in Chinese culture. They are as much a part of a Chinese birthday celebration as a birthday cake with lit candles is in many countries. Since noodles represent long life, it is considered very unlucky to cut it off.
Although westerners sometimes may be very sorry to see fish lying on a plate, in China a whole fish is a symbol of richness. In fact, at a party it is traditional to serve the whole fish last, pointed toward the valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come.
A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanut or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan.
The 50-minute program tries to bring something new by presenting more cultural elements(元素),such as eating habits and the quality of eating.

Everything that humans hear is in the form of waves(波). Just as the eye sees light waves in the form of colors, the ear hears sound waves in the form of noises. The ear and the eye turn these different waves into signals that the brain(大脑) can make sense of.
The ears and brain have an amazing ability to recognize(识别) particular sounds. For example, a mother often can tell when her baby is crying even if there are other crying babies in the same room. This is because the sound of her baby’s cry has special meaning to her and the brain has recorded its importance.
The ability to recognize sounds improves with experiences. As the brain receives information about sounds from day to day, it stores the information in its memory. When the brain hears new sounds, it gives meaning to them based on the information already in the memory. This is why certain words or songs can make a person happy. Often it is not the words or songs themselves that cause this feeling. The sounds are connected to happy memories for that person.
Another hearing process controlled by the brain is to decide where a sound is coming from. One ear is usually closer to the source(来源) of a sound than the other ear is. Sound waves are stronger when they reach the ear that is closer. They also reach the closer ear first. The brain recognizes these differences and uses them to decide the location of the source of the sound.
1.Which of the following shows the normal hearing process of a mother hearing her baby crying?
a. The ears receive the sound waves.
b. The mother recognizes her baby’s cry.
c. The baby’s turn the sound waves into signals.
d. The baby’s cry travels in the form of sound waves.
e. The brain connects the signals to the information in the memory.
A. d-a-c-b-eB. d-a-c-e-b
C. a-d-c-b-eD. a-d-c-e-b

A. lifestyleB. personality

In Lynch, an American businessman, had been going on vacation to a small Mexican fishing village for a number of years. One morning while going for a walk along the beach, he saw his friend Pablo Perez, a local fisherman. Martin watched Pablo unload his boat and pack the fish in a box.
Martin noticed Pablo was smiling and looked very happy. He could also see several large fish in the boat. Martin greeted Pablo and asked how long it took to catch the fish. “Just a new hours,” replied Pablo. Martin asked, “Why didn’t you stay longer and catch more fish?” “I have enough for my family,” Pablo said. “And what do you do with the rest of your day ?” asked Martin. “I take a nap, play with my children, spend time with my wife, and go into the village to see my friends and play cards. I have a full and busy life.” Martin explained that if Pablo worked longer hours and caught more fish, he could make more money. With the extra money, Pablo could buy more boats and catch many more fish. By selling the fish, Pablo could open his own factory and sell direct to supermarkets.
“Then what?” asked Pablo. “Well, you would probably have to move to Mexico City to run the business. Finally, you would be able to sell your business and make millions of dollars,” replied Martin. “How long will that take ?” asked Pablo.
Martin thought for a while and said it would probably take at least 15 years.
“And then what?” asked Pablo.
“Well, that’s the best part,” Martin said. “You will be able to retire, buy a house near the ocean, sleep longer, play with your children, spend more time with your wife, see your friends, and play cards.”
