Recently some American scientists have given a useful piece of advice to people in industrialized nations. They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago. ___【小题1】___
The scientists say that the human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sickness. ___【小题2】___ So they are called “disease of civilization”. Many cancers and diseases of the blood system are examples of such diseases.
Scientists noticed that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. __【小题3】___ However, a change in food is one of the main differences between life in ancient times and that of day.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy product, and they made very little use of grains.
___【小题4】___ We eat six times more salt than our ancestors(祖先). We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
___【小题5】___ But scientists say that we would be much healthier if we eat much the same way as our ancestors did, cutting the amount of fatty, salty and sweet food.

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steer them away from fast food shops and bad eating habits.

1.According to the text, what kind of children may eat more unhealthy food?

A．Those who often take exercise.

B．Those who often watch television.

D．Those who often walk to school.

2.The author thinks that children are becoming overweight because

A．their parents often cook meals for them

B．they are too busy to go out and play

C．they can' t choose what to eat

D．there are too many fast food shops around

3.The word "steer" underlined in the last sentence most probably means _______.

A．force             B．guide             C．expect            D．observe

4.The main purpose of the text is to _________.

A．tell a story                             B．provide facts

C．give advice                            D．compare opinions

Seven Health Facts about Coffee

When you’re considering your morning coffee, here are some health facts to keep in mind:

1. Coffee Reduces Your Risk of Diabetes (糖尿病)

In a 2005 review of nine studies, researchers found that for those that drank four to six cups of coffee per day, versus only two or fewer, their risk for Type 2 diabetes decreased by almost 30 percent. The number decreased by 35 percent when people drank more than six cups per day. And if you’re picturing yourself running around the office with your eyes bugging out of your head, no worries because caffeinated and decaffeinated coffees provided much the same results.

2. Coffee Fights Free Radicals (自由基)

We often forget that coffee is actually a plant and like all plant foods, the coffee bean contains more than 1,000 naturally occurring substances called phytochemicals, which may help prevent disease. Many of these phytochemicals are antioxidants which protect the cells from damage from free radicals.

3. Coffee Improves Memory and Cognition

Researchers reported that volunteers who drank caffeinated coffee in the morning performed better than nondrinkers on tests that involved learning new information. Coffee can also improve cognitive function as we age. One study found that combining coffee with a sweet treat had an even bigger impact.

4. Coffee Can Increase Osteoporosis (骨质疏松)

It’s true that coffee can cause the body to excrete calcium in urine. We don’t want the body to rid itself of calcium because this can lead to osteoporosis. According to The Diet Channel, about five milligrams of calcium is lost per every six ounces of coffee consumed. But these calcium losses can be counter balanced with two tablespoons of milk or yogurt per cup of coffee.

5. Coffee Causes Wrinkles

Even though coffee has antioxidants, if you drink too much of it, it can cause wrinkling of the skin. This is a result of dehydration (脱水) which is the worst thing for your skin. So when you’re drinking that morning cup or two, make sure that you’re pairing it with water. Even better, add one tablespoon of chia seeds to your water and let them sit for 30 minutes. The chia seeds keep you even more hydrated than regular water.

6. Coffee Can Actually Cause Weight Gain

The blood sugar changes that a caffeine high produces can contribute enormously to a strong desire for it, according to iVillage. Coffee is also socially connected to food. For example, we pair coffee with dessert or that morning powdered doughnut. Additionally, when we crash from our caffeine high that’s when we reach for all sorts of fatty snacks to keep us going.

7. Conventional Coffee Is Laden with Pesticides (杀虫剂)

The coffee plant is one of the most heavily sprayed crops. It’s coated with chemicals, pesticides, and herbicides, nothing you’d want to be swallowing. If you do drink coffee, make sure that it’s the organic variety, free from assorted chemicals that leech into our ground water and can make us sick down the road.

If you switch to decaffeinated coffee, make sure the caffeine (咖啡因) is removed in a natural way without the use of chemicals to do it. Often times, conventional decaffeinated coffee has more chemicals than regular.

   If you want to decrease the risk of diabetes by 35%, you need to take at least _____ cups of     coffee every day.

    A. seven            B. six          C. five             D. four 

If you are a heavy drinker of coffee, a far better way to avoid wrinkling of your skin is to drink water _____.

    A. less than usual  B. regularly        C. with sugar       D. with chia seeds

   Which of the following statements is wrong?

    A. Adding two spoons of milk to a cup of coffee can prevent calcium losses.

    B. Decaffeinated coffee has different effects from caffeinated coffee as to diabetes.

    C. Many phytochemicals protect the cells from damage from free radicals.

    D. The organic variety of coffee plant is free from assorted chemicals.

   The author has a/an _____ attitude towards drinking of coffee.

    A. positive     B. negative     C. objective        D. imaginative

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.

Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet .... We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brains to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)  instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.
【小题1】From Paragraph 1, we learn that ______.
