Zinc(鋅) is one of about 20 elements necessary for good health. It is present in the body in a very small amount but makes it possible for important chemical actions to be carried out in cells. Scientists are just beginning to discover how zinc and other elements work.
Researchers first studied zinc as a way to speed recovery. Dr. Waltor Powys formerly with the United States Air Force noted that the laboratory animals recovered faster when some matters were added to their food. One of these matters was zinc. Dr. Powys later tested the zinc treatment on an American airman recovering from medical operations. The airman who received zinc sulphate(硫酸鹽) recovered in half of the usual time. Other doctors studied persons who had a number of strange disorders. The doctors learned that all of these problems were caused by lack of zinc in the body. They treated these disorders successfully by giving the patients zinc sulphate.
The amount of zinc in the body can be found by examining blood and hair. A lack of this important element is not uncommon among people in both industrial and developing countries. Zinc is found in most high protein(蛋白質(zhì)) foods such as meat, milk, fish and eggs. It is also found in whole grains. But many people do not eat enough of these food. Food markets should add these elements so that more people could get needed amount of these necessary matters.
Which of the following statements is true?
A. Scientists found how zinc works a long time ago.
B. People need a large amount of zinc to be healthy.
C. Zinc allows important chemical actions to take place in cells.

Health food is a general term applied to all kinds of food that is considered more healthy than the types of food sold in supermarkets.For example，whole grains，dried beans，and corn oil are health foods.A narrower classification of health food is natural food.This term is used to distinguish between types of the same food.Raw honey is a natural sweetener，while refined(提煉的)sugar is not.The most exact term of all and the narrowest classification within health food is organic food，used to describe food that has been grown on a particular kind of farm.Fruits and vegetables that are grown in gardens，that are treated only with organic fertilizers，that are not sprayed with poisonous insecticides(殺蟲劑)，and that are not refined after harvest，are organic food.
In choosing the type of food you eat，then you have basically two choices：inorganic，processed(加工)food or organic，unprocessed food.A wise decision should include study of the reason why processed food contains chemicals，some of which are proved to be poisonous and that vitamin content is greatly reduced in processed food.
Bread is typically used by health food supporters as an example of a processed food. First, the seeds from which the grain is grown are treated with a chemical which is extremely harmful. Later, the grain is sprayed with a number of very deadly insecticides. After the grain has been made into flour, it is made white with another chemical which is also poisonous. Next, a dough conditioner is added along with a softener. The conditioner and softener are poisons，and in fact, the softener has sickened and killed experimental animals.
A very poisonous antifungal compound is added to keep the bread from getting moldy(發(fā)霉的)．
Other food from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want, even if it is poisonous. The alternative? Eat health foods，preferably the organic variety.
1．What is the passage mainly about?
A．Health food. B．The processing of bread.
C．Processed food. D．Poisons.
2．What do all of the additives in bread have in common?
A．They are all used to keep the bread from getting moldy.
B．They are all poisonous.
C．They are all organic.
D．They have all killed laboratory animals.
3．What happens to food when it is processed?
A．The basic content remains the same.
B．Vitamin is not available after processing.
C．The vitamin content increases a bit.
D．The vitamin content is greatly reduced.
4．We normally buy food on the basis of________.

Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast.Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白質(zhì)) and some fiber (纖維). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time.
1.The first paragraph mainly tells us that ______.
A．it is necessary to have a good breakfast every day
B．many adults are too busy to have breakfast every day
C．many adults go to work without having breakfast
D．many children go to school without breakfast
2.According to the passage, we feel tired at work probably because __.
A．we need to have a cup of coffee
B．we don’t have a good breakfast
C．our brains don’t work any longer
D．we don’t have enough sleep at night
3.What does the underlined sentence in Paragraph 2 mean?
A．Having a good breakfast can help you to finish your work.
B．Eating a good breakfast is enough for the whole day.
C．Breakfast is really the most important meal in a day.
D．You will be happier if you have a good breakfast.
4.We can learn from the last paragraph that ______.
A．it is healthy only to have beans and eggs for your breakfast
B．you mustn’t have meat for your breakfast
C．you should eat sugary foods if you feel hungry
D．you should eat something which has protein and fiber for breakfast

As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture（濕度）production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陳代謝）, make you feel inactive, and weaken your immune

Avoid Alcohol

Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（癥狀）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
