Do you sleep well? Some people get off to sleep as soon as their head hits the pillow, but  many others are not so lucky. In fact, the lack of quality sleep has become a public health issue around the world. According to me World Association of Sleep Medicine, 45 percent of the world's population suffer from sleep problems. One in eight people don't sleep well and are easily woken. 7.6 percent sleep less than 3 hours each night. Some even cannot fall asleep for several days in a row.
As a basic bodily and mental need, sleep is essential for our survival, it helps us to fight diseases, strengthen our memory, perform better in work and school and improve our quality of life. Lack of sleep is known to have a significant negative influence on health, both in the short and long term. Poor sleep has been associated with obesity, diabetes, weakened immune systems and even some cancers, as well as depression and anxiety.
The World Sleep Day, held on the third Friday of March, is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
To achieve this goal, we must figure out what causes sleepiness and sleeplessness.
Unhealthy lifestyle may be the first to blame. More and more people use cell phones and computers in bed, with many staying up until midnight. Modern technology does make our life convenient, but abuse of it ruins our health. Environmental conditions, such as temperature, noise, light, bed comfort also play an important Pole in one's ability to get proper sleep. Besides, improper evening diet, like a full or an empty stomach, coffee and alcohol all contribute to sleep problems. Of course, when it comes to causing poor sleep, stress from finances, family or work should never be ignored．
However, those who suffer from sleep disorders don't necessarily have to continue to do so -most sleep problems can be managed．
小題1:What can be inferred from Paragraph 1?
A．Nobody can stay awake for several days
B．Most people are going through sleep problems

British researchers have found that children’s IQ predicts their probability of becoming vegetarians (素食者) as young adults.
Recent studies suggest that vegetarianism may be associated with lower cholesterol (膽固醇), reduced risk of overweight and heart disease.
“We know from other studies that brighter children tend to behave in a healthier fashion as adults—they’re less likely to smoke, less likely to be overweight，less likely to have high blood pressure and more likely to take exercise.” lead author Catharine Gale said, “This study provides further evidence that people  with a high IQ tend to have a healthier lifestyle.”
In the study, Gale’s team collected data on nearly 8,200 men and women aged 30, whose IQ had been tested when they were 10 years of age.
“Children who scored higher on IQ tests at age 10 were more likely than those who got lower scores to report that they were vegetarian at the age of 30.”Gale said. 
The researchers found that 4.5 percent of participants were vegetarians. Of these, 2.5 percent were vegan, and 33.6 percent said they were vegetarian but also ate fish or chicken.
There was no difference in IQ score between strict vegetarians and those who said they were vegetarian but also ate fish or chicken，the researchers added.
One expert said the findings weren’t the whole answer，however.
“We don’t know the beliefs or attitudes of the parents of the children，nor do we know if there was a particular event that led these children to becoming vegetarian in their teens or adulthood.” said Lona Sandon, and assistant professor at the University of Texas Southwestern Medical Center at Dallas.
小題1:From the article，we know that ________.
A．brighter children are likely to become vegetarians when they are ten.
B．people with a higher IQ will not be overweight
C．brighter children are likely to have a healthier lifestyle
D．overweight may cause high blood pressure
小題2:What does the underlined word “vegan” in the sixth paragraph mean?
A．Someone who only eats vegetables.
B．Someone who chooses not to eat meat or fish.
C．Someone who likes eating meat and fish.
D．Someone who likes eating vegetables.
小題3:This study left some unanswered questions EXCEPT “________”．
A．Did the vegetarian children grow up in a family with a vegetarian parent?
B．Did the children eat a primarily vegetarian diet at the age of 10?
C．Were meatless meals regularly served in the participants’ families?
D．Did the vegetarian children really have a high IQ?
小題4:The main idea of the passage is that ________.
A．the low IQ children will be unhealthier when they grow up
B．being vegetarians can reduce the risk of overweight and heart disease
C．IQ is important to vegetarians
D．high IQ children are more likely to become vegetarian when they grow up

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?
　　While such vigilant(警覺的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
　　In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups. 
　　It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(預期壽命).
　　A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.
　　It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”
　　That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
小題1:Why do doctors recommend routine cancer screening for elderly people?
A．It is believed to contribute to long life.
B．It is part of their health care package.
C．The elderly are more sensitive about their health.
D．The elderly are in greater danger of tumor growth.
小題2:How do some researchers now look at routine cancer screening for the elderly?
A．It adds too much to their medical bills.
B．It helps increase their life expectancy.
C．They are doubtful about necessity.
D．They think it does more than good.
小題3:What is the conventional view about women screening for breast cancer?
A．It applies to women over 50.
B．It is a must for adult women.
C．It is optional for young women.
D．It doesn’t apply to women over 74.
小題4:Why do many doctors prescribe routine screening for cancer?
A．They want to protect themselves against medical disputes.
B．They want to take advantage of the medical care system.
C．They want data for medical research.
D．They want their patients to suffer less.
小題5:What does the author say is the general view about health care?
A．The more, the better.
B．Prevention is better than cure.
C．Better early than late.
D．Better care, longer life.

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.
First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above. Lastly, there are many people who do not eat meat because they just do not like the idea of killing animals for food. They believe that life, all life, is valuable , and that we do not have to destroy life to feed ourselves when there are other good sources of food.
小題1:According to the passage, people choose to be vegetarians for the following reasons EXCEPT________.
A．they want to stay healthy
B．they are too kind to put the idea of killing animals
C．they live in areas where meat supply is not adequate
D．they should not eat meat due to their religious belief

D．There are less health problems in modern society due to advanced medical care.
小題3:What does “vulnerable” mean in Paragraph 2?
A．Having low level of cholesterol.

People believe that climbing can do good to health. Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb，you’re wrong. Many Americans are learning to climb in city gyms(體育館). Here，people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.
　　How do people climb the wall? To climb，you need special shoes and a harness(保護帶)around your chest to hold you. There are ropes(繩索)tied to your harness. The ropes hold you in place so that you don’t fall. A beginner’s wall is usually about 15 feet high，and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it’s easy to see the new piece of metal. Sometimes, it’s not. The most difficult part is to control your fear. It’s normal for humans to be afraid of falling, so it’s difficult not to feel fear. But when you move away from the wall，the harness and the ropes hold you，and you begin to feel safe. You move slowly until you reach the top.
　　Climbing attracts people because it’s good exercise for almost everyone. You use your whole body，especially your arms and legs. This sport gives your body a complete workout. When you climb，both your mind and your body can become stronger.
小題1: What can we infer from the passage?
A．People are fairly interested in climbing nowadays.
B．It is impossible to build up one’s body by climbing.
C．People can only learn the skill of climbing outdoors.
D．It is always easy to see holding places in climbing.
小題2: The most difficult thing to do in wall climbing is .
A．to tie ropes to your harness B．to control your fear
C．to move away from the wall D．to climb straight up
小題3: The word “workout” underlined in the last paragraph most probably means .
A．settlement B．exercise C．excitement D．tiredness
小題4: Why does the author write this passage?
A．To tell people where to find gyms.

Happiness is contagious (有感染力的), as researchers reported on Thursday.
People with the most social connections — spouses, friends, neighbors and relatives — were also the happiest, the data showed. “Each additional happy person makes you happier,” Christakis said.
“Imagine that I am connected to you and you are connected to others and others are connected to still others. It is this fabric of humanity, like an American patch quilt.”
Each person sits on a different colored patch. “Imagine that these patches are happy and unhappy patches. Your happiness depends on what is going on in the patch around you,” Christakis said.
“It is not just happy people connecting with happy people, which they do. Above and beyond, there is this contagious process going on.”
And happiness is more contagious than unhappiness, they discovered.
“If a social contact is happy, it increases the likelihood that you are happy by 15 percent, ” Fowler said. “A friend of a friend, or the friend of a spouse or a sibling (兄弟姐妹), if they are happy, increases your chances by 10 percent,” he added.
A happy third degree friend — the friend of a friend of a friend — increases a person’s chances of being happy by 6 percent.
“But every extra unhappy friend increases the likelihood that you’ll be unhappy by 7 percent,” Fowler said.
The finding is interesting and it is useful, too, Fowler said.
“Among other benefits, happiness has been shown to have an important effect on reduced mortality (死亡率), pain reduction, and improved cardiac (心臟的) function. So better understanding of how happiness spreads can help us learn how to develop a healthier society,” he said.
The study also fits in with other data suggested in 1984 that having $ 5,000 extra increased a person’s chances of becoming happier by about 2 percent.
“A happy friend is worth about $ 20,000,” Christakis said.
小題1:It can be inferred that________.
A．happiness spreads as fast and widely as unhappiness
B．unhappiness spreads faster and more widely than happiness
C．happiness spreads faster and more widely than unhappiness
D．the spread of unhappiness has not been studied by researchers
小題2:Which of the following will increase your chances of becoming happier most?
A．Being in a party with a happy atmosphere.
B．A happy experience of your brother or your parents.
C．A happy trip to a foreign country of your friends.
D．Happiness of your friend’s friend.
小題3:What does Christakis mean by saying “A happy friend is worth about $ 20,000”?
A．A happy friend can help you bring in a wealth of $ 20,000.
B．A happy friend is a wealth which is worth about $ 20,000.
C．A happy friend increases your chances of being happy by 2%.
D．A happy friend increases your chances of being happy by 8 %.

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes (放松) little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts (變換) back and forth from one level of sleep to the other.
Though your mind slows down, you will dream from time to time. Scientists who study sleep point out that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend (建議) breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
小題1:The text suggests that not getting enough sleep might make you _____.
A．suffer from poor healthB．feel tired and nervous
C．dream more oftenD．breathe quickly
小題2:During REM, _____.
A．you move restlessly
B．you start dreaming
