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.

举一反三
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food,which includes lots of fruit, vegetables and fish,and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat,refined(精制的) grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood(全天然食物) had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.(解释原因) He also pointed in a paper that a Mediterranean(地中海) diet was associated(有关) with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood (可能)of you eating a Mediterranean diet is not very high.
Dr.Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people"s diets were becoming increasingly unhealthy. The UK population is consuming (消费)less nutritious, fresh produce and more saturated(饱和) fats and sugars.

B.The Mediterranean diet is the most healthy in the world. |
C.Many studies have been done on the Mediterranean diet before. |
D.The Mediterranean diet is not good for depression. |
A.our diets are closely related to our mental health |
B.the present study needs more facts and other information |
C.the UK population will become ill in the near future |
D.more saturated fats and sugars should be taken in |
A.To tell people what a healthy diet actually is. |
B.To prove people’s diets are increasingly unhealthy. |

D.To introduce some experts on the research team. |
Walk it off
Exercise is the most popular bad-mood buster. A person who’s in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or taking some quick exercise can do wonders towards changing that bad mood.
Tune it out
Listening to your favorite music for a while can also make tensions go away quickly, because music starts associations with past positive experiences we’ve had.
Give yourself a pep talk
Stop and listen to what’s on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper, including the pessimistic(悲观的)messages you’ve been giving yourself and then give optimistic answers.(“I still don’t have a job.” Vs” I have two interviews next week.”)
Reduce your stress
Relaxation techniques are wonderful mood-lifters. There include de3ep breathing, stretching and visualizing, all of which sound complicated(复杂的)but aren’t. One easy way to visualize, close your eyes and picture a favorite place, such as the beach. Another simple way to unhappiness is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, you realize you’re not helpless. You can make changes in your mood and life.
Avoid things that won’t improve your mood
TV may not help much: you need to increase your energy level and stimulate(刺激)your mind-something that the TV show “Neighbors” won’t do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta(面食), produce a calming effect on people who have a desire for them.
小题1:Which of the following may help us stop a bad mood?
A.Draw a picture of something complicated. | B.Put more sugar into your coffee. |

A.It helps raise your spirits. | B.It brings us a new technique. |
C.It is not complicated to do so. | D.It is an area to be easily controlled. |
A.You don’t have to be nice to your neighbors | B.you often feel powerful when in bad mood |
C.Some TV shows won’t energize you | D.Slow exercise can gets you out of bad mood |
A.How to Beat a Bad Mood | B.Energy Level and Stress |
C.Bad Mood and Our Life | D.How to Control Your Feeling |

Listen to her. When people feel sad, they often have the feeling of needing to be heard. So, listen carefully to what she is saying and do nothing else. Your friend will surely thank you for being the shoulder she can cry on.
Once you are done with listening, you can offer some advice or remain silent and let her feel everything and let it all out by crying. As a friend, you might think you should give her some advice. But if you have no idea about what to say, just remain silent and be there for her.
In order to be able to help your friend in need, don’t be sad for yourself. How can you help your friend when you are also feeling down?
A hug can make a difference in the word. It makes you feel warm and special. A hug makes you feel safe. So give your friend a hug when she needs it the most.
Spend more time with your friend who wants to be happy. Do things together like washing dishes, cleaning, or going out for fun. The more time you spend together, the stronger your friendship will become.
Sometimes, it is much better that you avoid a crying friend in your life. But by doing so, you are also keeping your friend at a distance and will make her wonder if you are her true friend. If you are there when she needs you, your friendship will be much stronger.

This is an old English saying. Have you heard it before? It means that we must go to bed early and get up early in the morning. If we do, we shall be healthy. We shall also be rich(wealthy) and clever(wise).
Is this true? Perhaps it is. the body must have enough sleep. Children need ten hours’ sleep every night. If you do not go to bed early, you cannot have enough sleep. Then you cannot think properly(适当地) and you cannot do your work properly. You will not be wise and you may not become wealthy!
Some people go to bed late at night and get up late in the morning. This is not good for them. We must sleep at night when it is dark. The dark helps us to sleep properly. When the daylight comes, we must get up. This is the time for exercise. Exercise means doing things with the body. Walking, running, jumping, swimming, and playing games are all exercise. If the body is not used, it becomes weak. Exercise keeps it strong. Exercise helps the blood to move ,brains(头脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better.
Our bodies also need air to breathe. Without air we die. We must have a lot of clean, fresh(新鲜的) air to breathe if we want to be healthy.
