Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.
WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.
Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.
"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.
Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."
1. The text is mainly about         .

“Love your neighbor as yourself" is a saying familiar to most of us. It means that you must have he ability to love and accept yourself in order to form and keep satisfying relationship with others self-esteem means accepting yourself for who you really are, and believing that you are indeed a ivdrthwhile person who is deserving of love and respect from others.
Self-esteem is our sense of how good we feel about ourselves. It is based on our judgment of urselves, not on other people's assessment, but simply on our own. Our self-esteem is not efaendent on our talent. Some very ordinary people feel very good about themselves, while other extranordinarily high achievers hold low opintions of themselves.
Self-esteem is the primary key to long-term stress managerment. Why? The first three sourees of stress are: predictable life event, unexpected changes and build-up of daily stresscs, These are much easier to handle when we believe in ourselves, A postive, healthy self-estcem gives us the “hardiness”(強健) to deal with the difficulities of life, and to see them as challenges to be met, rather than threals to be feared.
The forth category of streesons is entirely the result of a low self-esteem. It is the category of stress that is most common and tiring over the long run. This kind of stress cannol be overcome, or evenchanged, until the self-exteem problems that cause it are corrected.
Learning to love yourself for who y ou are is the key to overcoming stress. Self-esteem comes form the self, and cannot be promoted by others. A person who fecls that his self-estecm comes from the approval of those around him or her is bound to self-destruct(自毀), One cannot keep the level of “performance” required to please everyone else, especially if that performance disagrees with who you are and is simply a facade that makes you popular with the world. When the applause is gone, there is nothing left.
Only those who can feel the strength of knowing who they are and those who can feel good about that will survive the stresses of life. Sef-esteem is the basis of contentment and positive living.

Good nutrition and a balanced diet will help your children grow up healthily. No matter how old your kids are, you can take steps to improve nutrition and to encourage smart eating habits. Here are some suggestions.
Family Meals
Family meals are comforting for both parents and kids. Children like to guess what they are going to have and parents get the chance to introduce new foods to children and to find out which foods they like and which ones they don’t.
Teens may turn up their noses at your plan of a family meal. It is not surprising because they’re trying to establish independence. Yet studies find that teens still want their parents’ advice, so they use the mealtime as a chance to reconnect.
Stocking Up on Healthy Foods
Kids, especially younger ones, will eat mostly what they can get at home. That’s why it’s important to control the supply lines—the foods which you serve for meals and have on hand for snacks. You should have enough fruits, vegetables, lean meat and other good sources of protein, such as eggs and nuts, and healthy snacks, such as yogurt, peanut butter and whole-grain biscuits.
Being a Good Example
The best way for you to encourage healthy eating is to eat well yourself. Kids will follow the lead of the adults they see every day. By eating fruits and vegetables and avoiding fast food and sugary drinks, you’ll be sending the right message.
No Conflicts over Foods
Parents might find themselves shouting at children to get them to have healthy foods in front of them. This in fact can make children dislike what they are asked to eat.
Get Kids Included
Most kids will enjoy making the decision about what to make for dinner. Talk to them about making choices and planning a balanced meal. It can help prepare them to make good decisions on their own about the foods they want to eat.
1. Family meals provide the chances for parents to do the following things EXCEPT        .
A. guessing what kids are going to have                            B. finding what kids like and dislike  
C. introducing new foods to kids                               D. reconnecting with kids
2. The underlined sentence in the third paragraph probably means         .
A. teenagers may be interested in your plan of a family meal
B. teenagers may help you to make a plan of a family meal
C. teenagers may show no interest in your plan of a family meal
D. teenagers may refuse to help you to make a plan of a family meal
3. According to the article, which should NOT be done by parents?
A. Forming a healthful eating habit themselves.         B. Forcing kids to have vegetables.
C. Stocking up on some fruits at home.                     D. Making meal plans with kids.
4. What’s the best title for the passage?
A. How to eat healthily.                                    B. How to grow up healthily.
C. Help kids form healthful eating habits.           D. Help kids know what a healthful meal is.

It’s not a particular brain region that makes someone smart or not smart. Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume. Instead, new research shows, it’s the connections between very specific areas of the brain that determine intelligence.
“General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons(神經(jīng)元),”said Jan Glascher, lead author of a paper appearing in this week’s issue of the Proceedings of the National Academy of Sciences.
The results weren’t entirely unexpected, said Keith Young, vice chairman at Texas A﹠M Health Science Center College of Medicine in Temple, but “it proves that good communication between various parts of brain are very important for this general intelligence.”
“People noticed a long time ago that, in general, people who are good test-takers did well in a lot of different subjects,”explained Young. “If you’re good in mathematics, you’re also usually good in English. Researchers came up with this idea that this represented a kind of overall intelligence.”
Hoping to learn more, some experts located 241 patients who had some sort of their lesions (損害). They then diagrammed the location of their lesions and had them take IQ testes. “We took patients who had parts of their brain damaged, tested them on intelligence to see where they were good and where they were bad, then we connected those scores across all the patients with the location of the brain lesions,”Glascher explained. “That way, you can know the areas that are associated with reduced performance on these tests, which means these areas are really important for general intelligence.”
“These studies suggest results based on the absence of brain tissue (組織),”added Paul Sanberg, famous professor and director of the University of South Florida Center. “It allows them to systemize and find areas important to intellingence.”
1. Which of the following is the best title for the passage?
A. General Intelligence Depend on Brain Volume
B. Scientists Explain Mysteries of Intelligence
C. Science Research Done on Human Brain
D. Brain Lesions Cause Patients Stupid
2.According to Keith Young, we can infer that_____________.
A. the parts of brain are working smooth on their own
B. a person good at maths has obstacles learning languages
C. overall intelligence will make a person successful
D. Jan Glascher’s article really shocks the world
3. Why did experts locate 241 patients with some sort of brain lesions?
A. To diagram the location of their lesions.
B. To take IQ tests to the patients.
C. To know more about the secrets of intelligence.
D. To take better care of the patients.
4.From the diagram, the experts concluded that_____________.
A. the absence of brain tissue will influence intelligence
B. the brain lesions can improve the performance
C. patients with brain lesions will get a high score
D. Some areas totally determine the ability of intelligence

Cuts
Bleeding can usually be stopped by applying pressure to the cut for 2 or 3 minutes. The cut can then be carefully inspected. If it has bled freely any germs will normally have been washed away by the blood.
Apply a plaster dressing firmly, bringing the edges of the cut together so that it knits quickly. Keep dry for 1 to 2 days.
If the cut is deep and the edges cannot be pulled together with a dressing consult the doctor or the practice nurse. A tetanus (破傷風(fēng)) injection may be needed.
Grazes
Dirt will often enter a graze caused by falling on a hard or rough surface. It must be cleaned out carefully with an antiseptic solution. (消毒液)
After cleaning, leave the graze uncovered. Exposure to the air will cause a scab to form. This will gradually fry and fall off.
It is not a good idea to apply a dressing. This may stick to the graze or make it complete wet and infected.
Bruises
Bruises are very common in children. They normally get better in 7 to 10 days Parents sometimes worry that a bone may be broken, but if in doubt consult the doctor.  If a child gets up at once after a fall and moves about normally, it is unlikely that a bone has been broken.
Severe bruising can be treated by: Rest for 24 to 48 hours .In the case of a badly bruised leg, the limb should be raised. Lying in bed is the easiest way to do this.
A bad compress may ease a bad bruise if applied at once. This is made by leaving some material in water and applying it to the bruise.
Insect bites
These are common in the summer .They look like spots about 1/4’’across .They are very itchy (癢) and usually appear on exposed parts, e.g. arms and legs.
The itching can be relieved by calamine lotion (護膚藥水).
Burns and scalds
Minor burns and scalds cause redness of the skin. Immediate treatment by pouring cold water over a burn is often helpful. If burns cause the skin severe hot or break the skin, the doctor should be turned to.
Sunburns should, if possible, be prevented by avoiding long exposure and covering exposed areas as much as needed. It may be treated by calamine lotion to relieve the pain.

  Sports can help you keep fit and get in touch with nature .However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(球場) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
