The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives, which we eat, are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

A. Drug and Food   B. Cancer and Health   C. Food and Health   D. Health and Drug

B. Some of the additives in our food are added to the food itself and some are given to the living animals

D. Food may cause forty percent of cancer in world.
63. How has science done something harmful to mankind?
A. Because of science, diseases caused by polluted food have been virtually eliminated.
B. It has caused a lack of information concerning the value of food.
C. Because of the application of science, some potentially harmful substances have been added to food.

C
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（湿度）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（新陈代谢）, make you feel inactive, and weaken your immune system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
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（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
44．To fight A/H1N1 infection, it’s helpful for us to_______ .
A．sing “Happy Birthday” while washing hands

B
All of us eat every day, but most of us don’t understand nutrition. We often make mistakes in talking about good diet.
For example, many people think that foods such as rice, bread and potatoes will make one grow fat. In fact, these foods are very good to one’s health. They are good sources of many vitamins. And in comparison with steak and beef, they contain less amount of calories.
Some people don’t like canned(罐装的) or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys good qualities of vegetables. Vegetables cooked in too much water can use a large amount of vitamins.
It is widely believed extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better.
It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don’t come from the soil. However, the minerals(矿物质) in a plant depend on the minerals in the soil.
In short, there are many false ideas about nutrition. We need to correct them.
1. This passage is mainly about_______.
A. nutrition B. vitamins C. vegetables D. health
2. Rice, bread and potatoes do good to people’s health mainly because_______.
A. they make people fat B. there are lot of vitamins in them
C. they contain less amount of calories compared with steak and beef.
D. both B and C.

A. they think fresh vegetables contain less vitamins
B. they think fresh vegetables contain more vitamins than the canned or frozen ones
C. they don’t think the canned or frozen vegetables are fresh
D. they don’t think the canned or frozen vegetables taste as good as the fresh ones
4. Which of the following is true according to the passage?
A. Many people know almost everything about nutrition.
B. Food such as rice, bread and potatoes make people fat.
C. vegetables grown in poor worn-out soil may have the same amount of vitamins as vegetables grown in rich soil.
D. extra vitamins provide less energy.
5. The point of the passage is that______.
A. the minerals in a plant depend on the minerals in the soil
B. people make mistakes when talking about good diet
C. taking more vitamins than the body needs doesn’t make it function better
