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 (***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.
小题1: 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 |
| A．less than usual | B．regularly | C．with sugar | D．with chia seeds |
| 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. |
| A．positive | B．negative | C．objective | D．imaginative |

Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛).Ability to sleep is largely a habit . The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(药）should never be taken except when suggested by a doctor.
小题1:How many hours are usually enough for the health of a pupil?

Then, consider this: you might be in a state of sub-health（亚健康）. Sub-health, also called the third state or gray state, is explained as a borderline（界限）state between health and disease.
According to the survey by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.
Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub-health, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements -- vitamins and other elements that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract（消化道）. They also say that a balanced diet is very helpful in avoiding sub-health.

ise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little mire than one second to be affected.An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.
小题1:.

(苗条) without any effort. But a lot of people do put on too much weight and don’t like it. The question is, what can thy do about it?Some believe exercise can be helpful. But the trouble is that it only makes you want to eat more. You might sweat out a couple of pounds playing tennis or climbing a mountain, but you put it all back on again with a big steak or bread and jam.
A helpful way is food choosing. But what sort of food should you choose? Some believe that the less they eat, the slimmer they will be. They don’t eat anything until they become weak with hunger. Some stick to milk and bananas. You’ll find you need a lot of bananas, and unless you live where they grow, they aren’t cheap. Another says that if you eat things like hard-boiled eggs, and apples with their skins on which are hard for your stomach to digest (消化), the more you eat, the thinner you get. This is because you use up the fat in your body to get the energy to digest the food.
For most of us these methods are too extreme (极端的). The simplest way is just to cut down on the carbohydrates (糖
类) that means not eating bread, potatoes, cakes, sugar, rice, and so on and eating anything else you like. It’s straight forward and often quite effective.Still others like to be more scientific. They are calorie countries. They get a table, which tells them that, for example, 100 grams of roast let of lamb gives you 330 calories and a 50 gram helping of Yokshire pudding gives you 130 calories.
