Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts 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 bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only 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(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
According to the passage,what is the function of fluoride?

A.Making the surface on teeth much cleaner.
B.Protecting gums from being infected.
C.Keeping holes on teeth from forming.
D.Slowing down bacterial growth and acid production.

The underlined phrase “interfere with” in Para.5 probably means “________”.

A.do harm to B.account for
C.contribute to D.stand for

What is the purpose of the author in writing the passage?

A.To warn us of the deadly infections of gums and teeth.
B.To introduce the advantages of fluoridated toothpaste.
C.To draw our attention to the dental care of young children.
D.To present the research results about dental care.

When something goes wrong,it can be very satisfying to say,“Well, it’s so-and-so’s fault.” or “I know I’m late,but it’s not my fault;the car broke down.” It is probably not your fault,but once you form the habit of blaming somebody or something else for a bad situation,you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stop on for success.
According to the passage, winners .

A.deal with problems rather than blame others

One of the greatest warriors(勇士) of history, Genghis Kahn, came from the Mongolian people. He controlled many countries in Asia and Europe because of his bravery and leadership in battle. This time period was known as the Yuan Dynasty in the 13th and 14th centuries.
Genghis decided to go hunting one day and many of his warriors went with him. Genghis had his favorite hawk on his wrist. The hawk was trained to fly high in the air to look for game like deer, rabbits or wild birds. When his bird flew to the ground, Genghis would follow it and shoot the wild game with his arrows. It was his favorite hobby.
This particular day, game was hard to find. Toward evening, Genghis sent all the men home and decided to go another way by himself. He even let his hawk go, thinking it would fly home as well. He became thirsty so he stopped by some rocks where he noticed water was dripping. He took a cup from his pack and filled it slowly. When he put it to his mouth, he was surprised for his hawk came and spilled (使溅出) all the water in his cup.
He thought this was very unusual so he filled the cup again. The hawk rushed down and knocked the cup free from his hand. Genghis was now thirsty and angry. As he filled the cup a fourth time, he drew his sword to stop the bird interrupting him. As the bird flew down, Genghis killed it but his cup fell deep into the rocks in the scuffle (扭打).
He decided to crawl up the rock of the mountain to find the source of the water. He found a pool and noticed a huge poisonous snake was dead in the water. He realized the hawk had saved his life. His anger had caused him to kill his favorite bird. In his despair (绝望), he promised to make sure of everything before he would become angry again.

Why play games? Because they are fun, and a lot more besides. Following the rules, planning your next move and acting as a team member are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .
Many children’s games have a practical side Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones, which sharpens the hand-eye coordination(协调)needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.
Through playing hide-and-seek, children are expected to learn to ________.

A.be a team leader B.obey the basic rules

Reading is the key to success in all school subjects. With a bit of creativity, you can help your child enjoy reading more, and encourage him to do more!
Buy or borrow a lot of “fun” books. Choose books that are slightly below his level of reading ability. Don’t forget what your child likes to do when choosing books for him. Don’t comment about the books. Simply leave the books lying on the table where your child is sure to see them. Computer games are not as harmful as most parents usually think them to be. Instead, you should take advantage of your child’s love of computer games to purchase those that require a lot of reading and avoid those that are simply computerized video games.
Buy your child a bedside reading lamp, or a tiny book light. Tell him that from now on, he must be in bed by a specific time (say 8:30) and that he can either sleep or read. Most kids will do anything else rather than go to sleep, so there’s a chance you’ll create a new bedtime reading habit.
Many children will read when they are sitting alone having a snack, or when they have a few minutes of unplanned free time. Put a box of books and magazines near the kitchen table so that reading material is available.
Often, once children learn to read independently, parents stop reading to them. This change of routine causes great sadness to a child who has come to love falling asleep as you read. Even a teenager will enjoy being read to if you pick books that interest him. Select books together, and make sure they’re ones you enjoy as well, so your enjoyment will come through as you read to them.

To make children become interested in reading, parents should _______.

A.choose books based on their interest
B.tell them what they can learn from these books
C.choose the easiest books for them to read
D.always read books together with them

When my grandmother was raising me in Stamps, Arkansas, she had a particular routine(惯例)when people who were known to be whiners entered her store. My grandmother would ask the customer, “How are you doing today, Thomas?”
The person would reply, “Not so good today, Henderson. You see, it’s this summer heat. I just hate it. It just makes me tired. It’s almost killing me.’ Then my grandmother would stand calmly, her arms folded, and say, “Uh-huh, uh-huh.”
As soon as the complainer was out of the store, my grandmother would call me to stand in front of her. Then she would say the same thing she had said at least a thousand times, it seemed to me. “Jane, did you hear what so-and-so complained about?” And I would nod. Grandmother would continue, “Jane, there are people who went to sleep all over the world last night, poor and rich and black and white, but they will never wake again. Those dead people would give anything, anything at all for just five minutes of this weather that person was complaining about. So you watch yourself about complaining, Jane. What you’re supposed to do when you don’t like a thing is change it. If you can’t change it, change the way you think about it. Don’t complain.”
