小题4:

A．advice

Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation(attraction) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
小题1:What do most people think causes bad behavior?

A．Being forced by others.	B．Not having enough will power.
C．Enjoying their first experiences.	D．Following the examples of their friends.

小题2:The author mentions his experience in the third paragraph to prove ____.

A．will power helps develop bad habits sometimes

B．drinking beer is harmful to the health of teenagers

C．self-control should be developed when one is young

D．everyone can be challenged by different temptations

小题3:In the last paragraph, the author stresses(强调) that ____.

A．without self-control, no one can succeed

B．bad habits don’t always lead to bad results

C．applying self-control correctly is important

D．people can develop wisdom from bad behavior

小题4:What would be the best title for the passage?

A．My First Sip of Beer	B．Do You Have Will Power ?
C．Will Power Benefits Us	D．Dark Side of Self-control

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising good shapes and new look to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually, Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
小题1:It can be inferred that ads mentioned in the text are_____.

小题2:The Relaxacisor is mentioned as______.

A．a product which was designed to produce electricity

B．a product whose distributor was involved in a legal case

C．a successful advertisement of a beauty product

D．an example of a quality beauty product

小题3:The author intends to______.

A．make consumers aware of the promoters’ false promise

B．show the weakness of the law on product safety

C．give advice on how to keep young and beautiful

D．introduce the organization of FDA

小题4:Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.

Depression(抑郁症)is a serious problem today．Depression causes workers to be unproductive，causing companies and countries to lose billions of dollars．One expert says that depression is like cancer because it is “widespread，costly and deadly”．Depression hits one person in five around the world．
Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone。Over any six-month period，between five to seven percent of the world's population will be suffering from a serious depression．
suicide(自杀)rates among people suffering from the disease in its extreme，or clinical form were 80 percent higher than in the population at large，and sufferers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping，getting up on time，and doing work productively．
Depression，which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate-making it impossible for employees and managers to work efficiently．

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
小题1:The text mainly discusses the relationship between .

A．heart problems and air quality

B．heart problems and exercising

C．heart problems and smoking

D．heart problems and fatty food

小题2:The underlined word “modest” in Paragraph 3 most probably means .

A．relatively high	B．extremely low
C．relatively low	D．extremely high

小题3:What can we learn from the text?

A．Eating fatty food has immediate effects on your heart.

B．The EPA conducted many studies on air quality.

C．Moderate air quality is more harmful than smoking,

D．Stricter regulations on pollutants should be made.

小题4:The author’s purpose of writing the text is most likely to .

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage．Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
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 go through a machine. The machine cooled the blood. Then the machine sent the 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．
小题1:The biggest difficulty in operating on the damaged brain is that____ ．

A．the time is too short for doctors

B．the patients are often too nervous

C．the damage is extremely hard to fix

D．the blood-cooling machine might break down

小题2:The brain operation was made possible mainly by____ ．

A．taking the blood out of the brain

B．trying the operation on monkeys first

C．having the blood go through a machine

D．lowering the brain’s temperature

小题3:With Dr. White’s new idea, the operation on the damaged brain____ ．

A．can last as long as 30 minutes

B．can keep the brain’s blood warm

C．can keep the patient’s brain healthy

D．can help monkeys do different jobs

小题4:What is the right order of the steps in the operation?
a．send the cooled blood back to the brain 　　b．stop the blood to the brain
c．have the blood cooled down 　　 d．operate on the brain

阅读下列短文，从每题所给的四个选项中(A、B、C和 D)中，选出最佳选项，并在答题卡上将该项涂黑。
A
Most of us feel upset if we miss just one meal, and if we try to go without food for 12 hours we would really be uncomfortable. But there are some people who seem able to “fast” for very long periods.
Various records are claimed for long fast, but in most cases there is no medical proof and so the records are doubtful. One South African woman claimed that she lived for 102 days on nothinig but water and soda water.
There are great differences among living things in the ability to survive without food. For example , a tick（扁虱）, which lives on animals, may survive a whole year. Warm-blooded animals use up their stores of food in the body more quickly.
In fact, the smaller and more active the animal, the more quickly it uses up its reserves. A small bird starves to death in about five days, a dog in about twenty. In general, we can say that a warm-blooded creature will die when it has lost about half its normal weight.
This matter of weight is important. Man and other creatures live in a state of metabolic equiplibrium（新陈代谢的平衡）which means maintaining the body weight once a certain point has been reached. This regulation of body weight is done by thirst, hunger, and appetite.
When your blood lacks nutritional materials, this registers（记录）in the hunger center of the brain and you feel “hungry”. The body is crying out for any kind of fuel(food). And it is our appetite that sees to it hat we chooose a mixed diet, which is the kind the body needs.
小题1:According to this passage, a man will die _________.

A．when a certain point in losing weight has been reached.

B．when his blood lacks nutritional material

C．when his normal weight is lost

D．when he goes without food for more than 12 hours

小题2:The word “fast” in Paragraph 1 can best be replaced by ________.

A．eat no food	B．live merely on water and soda water
C．live on nothing	D．remains alive for a long time without food

小题3:A tick can survive much longer than a bird because ________.

A．a tick lives on animals	B．a tick is much smaller
C．a bird is more active	D．both B and C

小题4:A person feels hungry _________.

A．if he doesn’t choose a mixed diet

B．because his body cries out for food

C．when soemthing is wrong with regulation of body weight

D．if there are not enough nutritional in his blood

小题5:From the passage we can infer that the author ________.

A．believes the South African woman very firmly

B．does not believe the South African woman at all

C．is not certain whether the South African woman’s claim was true.

D．is doubtful whether there was such a South African woman
