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 12?-year-?old 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.

How to become a better reader
Language and literacy(读写能力) are among humans’ greatest inventions. Evolving(演变) over the course of human history, languages are a reflection of our cultural and societal attitudes. Today, surrounded(包围) by social media, television, movies, and, of course, books, the ability to read and write is important to expressing one’s feelings. Most humans acquire language in early childhood and speak fluently when they are about three years old, but our continued relationship with language gives shape and meaning to our lives. 1.
(1) Take it slow. Many readers feel that they read too slowly, especially compared with others. 2. The best readers are flexible(灵活的) — slowing down when needed — and always have a dictionary at hand.
(2) Read aloud. When humans first began reading written words, it was unusual to read in silence. 3. Try listening to the author reading their own work — you’ll be surprised to find how clearly it comes through on the page.
(3) Write. Writing and reading go hand-in-hand: how and what you read affects how and what you write, and the best readers often make the best writers. But while much can be learned from close, repeated readings, there are many pleasures to language that can only be experienced through the practice of writing. 4.
(4) Tell your friends. All of the literature is essentially communication from an individual’s inner voice to an audience. 5. It’s a good way to see the world from someone else’s eyes and, in the process, carefully examine your own reaction to what you’re reading.
A. But the truth is that the faster you read, the less likely you are to understand fully what you’re reading.
B. Can you remember the first piece of writing that transported you to another world?
C. There is something magical about sharing books with friends or a book club.
D. Try writing every day for a month, and you will never read the same again.
E. Reading out loud is one of the best ways to improve your reading ability.
F. Here are 4 ways to become a better reader.
G. In no time, you’ll be appreciating novels like fine wine.

Many people in high school cannot wait to go to college and leave their hometowns behind.Questions arise, though,when it comes to all of the decisions involved in choosing a college.
One of the first considerations may be financial.State and public colleges are often the least expensive. Often, though,the better colleges are private and more expensive.It is sad when gifted students cannot attend a college of their choice just for financial reasons.
Another major factor is location.Whether the college is in a small town or large city can have a major impact on its activities.A water lover probably will be more comfortable spending four years near an ocean or a lake.Those who cannot tolerate heat will probably be more comfortable at a northern college.
School size also plays a major role in the decision process.If you want to get to know your teachers and avoid feeling like just a number,a small college is suitable.For those of you who consider yourself a "people person" and want a wide range of activities,a large college is more fitting.
Your area of interest is another factor to consider in the decision-making process if you want to get the most from your education.The whole point of college is to learn what is of interest to you.
Finally,one must take into consideration the colleges to which you can realistically be accepted.An Ivy League school for an average student would probably not be a good match.Similarly,an average school for an above-average student would not work well.The college should provide enough of a challenge for the student to work hard. Although there may not be the perfect college out there,there probably will be one that is close.Those who cannot find a suitable college are probably not looking hard enough.
1.What's the main idea of the text?
A. Procedures of choosing a college.
B. Difficulties in attending a school.
C. Pros and cons of going to college.
D. Considerations in choosing a college.
2.We can infer from the passage that .
A. an Ivy League school is probably a state college
B. a small college may bring you a sense of emptiness
C. gifted students are likely to choose private colleges
D. an average school isn't suitable for an average student
3.A "people person" in Paragraph 4 probably refers to .
A. a person who tends to be alone
B. a person who is good at sociality
C. a person who is afraid of teachers
D. a person who is accustomed to a noisy atmosphere
4.What does the author think of choosing a college?
A. A small college is a better choice for shy students.
B. A northern college has a more comfortable climate.
C. The location of a college is more important than the size of it.
D. You will always find a suitable college if you look hard enough.
