1 . The eyes are the windows of the soul (心灵). Having a pair of bright, clear eyes is very important, so we should protect our eyes throughout our lives.

    1    

Don’t read while lying down or walking. Relax after every hour of reading. Keep a distance from the TV set when you watch TV and give your eyes a rest every 30 minutes. Don’t stare at (盯看) the sun or try to read in the darkness.     2     This can damage your eyes easily.

Get your eyes checked often.

Not many people have this habit, but it is necessary. If you feel that there is something wrong with your eyes, get them checked quickly.     3    

Rest your eyes whenever you can.

You can close your eyes for a few seconds or look into the distance for one or two minutes. A small break will relax your eyes.     4    

Besides, be careful when you choose your glasses.     5     Make sure your glasses are right for you. If you don’t feel right, get your glasses changed.

3 . Bad teeth may be painful and it’s getting worse without treatment. They can even ruin your life. Illness of the teeth can find its way into the blood system. This can increase the chances of a heart disease or other illnesses.

Experts say good care for teeth should start at birth. Mothers’ milk is the best food for the healthy development of teeth.

But dentists say a baby’s mouth 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, give him only water.

When a baby’s 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. Young children often eat toothpaste (牙膏) when they brush their teeth, so they should be carefully watched when they brush their teeth.

Parents often ask what effect thumb sucking (吮拇指) might have on their baby’s teeth. Experts generally agree that this is fine early in life. Most children stop sucking their thumbs by the age of four. If it continues, parents should talk to their children’s dentists or doctors.

Dentists say children should have their first dental visit by the time they are one year old. They say babies should be examined when their first teeth appear, usually at around six months.

Protecting our eyes to enjoy a bright world

The health of children’s vision is facing a growing threat.

7 . What is the best sleep position for your health?

It’s difficult to control what sleeping position we naturally fall into, as our body will subconsciously all into the most comfortable position for us. However, some positions are better for you than others and come could hold back your health and wellbeing.     1     .

If you sleep on your side

More than 60 per cent of people sleep on their side. Often our body naturally moves to this position, which is linked to when we were in the womb in the foetal(胎儿的) position.    2    It offers a number of benefits to your body, from promoting healthy spine alignment(脊椎对齐) which can help to prevent back pain to reducing heartburn and snoring(打鼾).

If you sleep on your back

Lying on your back is the second most popular sleeping position and offers just as many benefits as side sleeping. When you’re sleeping on your back, it’s easy to keep alignment and to also evenly distribute your weight.     3    

If you sleep on your stomach

Sleeping on your stomach is the least common sleeping position.     4     . And those who sleep on their stomach could put themselves at risk of a less restful night’s sleep. The stomach offers the least amount of back support and can increase pressure on the spine which may cause pain once you wake up.

    5     You should consider various factors such as if you snore or suffer sleep problems, or if you often have back and neck pain. Side sleeping has been noted as the best position for the body, so this is probably one to try and get into the habit of trying, but again, it all depends on you.

9 . For hundreds of years, scientists learned about the brain by observing people recovering from injuries. Many with an injury on the left side of the brain had problems understanding or using words. From this, doctors reasoned that the left brain must manage speech and language. They didn’t know, though, if speech and language centers were on this side in everyone. The finding of a new study may be able to tell the answer.

In the new study, researchers used fMRI (功能性磁共振成像) to watch brains in action as 39 children and 14 adults tried to understand sentences. Each fMRI scan (扫描) produced many pictures of the brain. Patches of color in each image highlighted which parts of the brain were getting the most blood. This is a sign that they were turned on and active.

To the researchers’ surprise, the left side of the brain was not the only part that was turned on in the children. Both sides became active when they tried to understand a sentence. That activity in the right brain started to fall in children who were older. By age 19, no activity showed up on the right. All speech-and-language processing now was taking place only on the left. The move from two-sided to one-sided language processing takes place gradually. It starts around the time we learn to talk.

Elissa Newport, who led the study, finds it exciting that children have speech centers on both sides of their brains. “If both sides of their brains can pitch in, this may also explain why left-brain injuries often are not as damaging in young children as in adults,” said she.

Children process language like “mental switch-hitters”. So, the next time you think your parents or older siblings (兄弟姐妹) don’t understand you, give them a break. They could be using just a smaller part of their brains.
