Bad teeth can be painful — and worse. They can even be deadly. Infections (感染）of the gums (牙龈）and the teeth can cause bacteria (细菌）to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk. For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿 保健）he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物）to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (法琅质)， the hard surface on teeth, to help prevent holes from forming.
31.According to the passage, bad teeth can be ____________.
A.painful B. deadly C.preventive D.incurable
32.The writer uses the boy's death as an example to show that _______?
A. not only adults but the young may suffer from teeth problem

33. What's the main idea of paragraph 4 and 5?
A. How to develop babies' teeth. B. Why to protect babies' teeth
C. How to keep babies' teeth clean D. Why to keep babies' teeth clean
34. The passage tells us that _______.

When a child is told he is “uncool”, it can be very painful. He may say he doesn’t care, and even act in ways that are different from cool on purpose(故意地）. But these are simple ways to deal with sadness by pretending it’s not there.
Helping a child feel better in school had to be careful. If you say, “Why are you worried about what other children think about you? It doesn’t matter!” Children know that it does matter. Instead, an active way may be best. You could say, “I’m going to do a couple of things for you to help you feel better in school.”
If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class things. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child’s popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.
There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider “super” .When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.
What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.

Stop eating yourself stupid we all know that poor nutrition can lead to bad health and even weight gain. Now add “lack of intelligence” to the growing list. A recent study has found that what you eat could very likely play a role in how smart you are.
According to the study, rats fed a high-fat diet for 10 days showed signs of weakness and even had trouble finding food that was waiting for them. 1. Actually a high-fat diet could weaken our intelligence--but so can a low-calorie diet. The trick appears to lie in finding a nice balance.
Here are ways to achieve that happy balance and make you smarter through diet, exercise and improving your brain power.
Figure out how many calories you need to maintain your weight. __2.__ If you need to drop a few pounds, take away the number you get by 400 calories; consume that number of calories each day until you drop the weight.
__3.__Aim for healthy foods that include good amounts of protein, fiber, fruits and vegetables, healthy whole grains, healthy fats and plenty of water. Well! Remember: All work and no play makes Jack a dull boy. Read a book. Try a new recipe. Do some puzzles. __4.__
Exercise regularly with a positive attitude. Aim for at least three 30-minute training sessions a week(but more is better). I like simple exercise such as walking, but anything that raises the heart rate is good. _5._ Combine them! Some people like to listen to classical music such as Bach or Mozart, but rock music lovers will be happy to learn that this kind of music can help make them smarter as well.
A．You may be fond of music, too.
B．Your health depends on your exercise plan.
C．Aim to get this number of calories each day.
D．Don’t forget to exercise your mind while doing so.
E．You may be wondering what this has to do with us.

Street art can be found on buildings, sidewalks, street signs and even trash cans from Tokyo to Paris to New York City. This special kind of art can take the form of paintings, sculptures, cloth or even stickers. It has become part of a global visual culture. Now, even art museums and galleries are collecting the works of street artists.
It is not easy to provide an exact history of the street art movement. This kind of art has developed in many kinds of ways in places all over the world. Also, because it is illegal to paint on public and private property without permission, street artists usually work secretly. This secretive nature of street art and its countless forms make it hard to define exactly. And people have different opinions about the movement. Some think street art is a crime and destroys property. But others see this art as a rich form of non-traditional cultural expression.
Many experts say the movement began in New York City in the 1960s. Young adults would use paint in special cans to spray their “tag” on walls and train cars around the city. This tag was a name they created to identify themselves and their artwork. This colorful style of writing is also called graffiti (涂鸦). It is visually exciting and energetic. Some graffiti paintings were signs marking the territories of city gangs or illegal crime groups.
Graffiti also became a separate movement expressing the street culture of young people living in big cities. Graffiti art represented social and political rebellion (叛逆). This was art that rejected the accepted rules of culture and power. These artists could travel around areas of the city making creative paintings for everyone to see. Sometimes this street art created a conflict between artists and city officials. Graffiti artists created their images and city officials quickly painted over them.
During the 1980s, two New York painters—Keith Haring and Jean Michel began showing their work in art galleries and museums. This is when street art started to become part of the more general popular culture.
1.What can we infer from the first paragraph?
A. Street art has become popular and is accepted as a kind of culture.
B. Street art is very special compared with other forms of popular art.
C. Many people are beginning to learn street art.
D. Street art is better developed in big cities than in rural areas.
2.Which of the following statements is TRUE according to the passage?
A.“TAG” was a word created by people to distinguish street artists and the other artists.
B. There are three reasons explaining why it is hard to define the history of street art.
C. The movement of street art began in the 1980s in New York City.
D. All the people don’t think that the street art is a rich form of cultural expression.
3.The city officials used to get rid of graffiti probably because ________.
A. they caused arguments between people
B. they were ugly in someone’s eyes
C. they were not painted under proper guidance
D. they didn’t express traditional culture
4.Which is the best title of the passage?
A. The Way to Become a Street Artist
