Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (細菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精煉米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (維生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
小題1:The underlined word “cure” in Paragraph 1 probably means ______.
A.a(chǎn) medical treatment B.a(chǎn) kind of vitaminC.a(chǎn) kind of germD.a(chǎn) kind of rice

D.To make money by selling them.
小題4:If a person doesn’t get enough vitamins in his diet, he’d better ______.

小題5:We can learn from the passage that ______.
A.beri-beri was caused by chickens

Grandpa Nybakken loved life—especially when he could play a trick on somebody. At those times, his large Norwegian frame shook with laughter while he pretended innocent surprise, exclaiming, “Oh, forevermore!” But on a cold Saturday in downtown Chicago, Grandpa felt that God played a trick on him, and grandpa wasn’t laughing.
Grandpa worked as a carpenter. On this particular day, he was building some boxes for the clothes his church was sending to an orphanage abroad. On his way home, he reached into his shirt pocket to find his glasses, but they were gone. He remembered putting them there that morning, so he drove back to the church. His search proved fruitless.
Suddenly, he realized what happened. The glasses had slipped out of his pocket unnoticed and fallen into one of the boxes, which he had nailed shut. His brand new glasses were heading for China!
The Great Depression was at its height, and Grandpa had six children. He had spent twenty dollars for those glasses that very morning.
“It’s not fair,” he told God as he drove home in frustration. “I’ve been very faithful in giving of my time and money to your work, and now this.”
Several months later, the director of the orphanage was on vacation in the United States. He wanted to visit all the churches that supported him, so he came to speak on Sunday night at my grandfather’s small church in Chicago. Grandpa and his family sat in their usual seats among the small congregation(教堂會眾).
“But most of all,” he said, “I must thank you for the glasses you sent last year.”
“Even if I had the money, there was simply no way of replacing those glasses. Along with not being able to see well, I experienced headaches every day, so my co-workers and I were much in prayer about this. Then your boxes arrived. When my staff removed the covers, they found a pair of glasses lying on the top.” After a long pause, he continued, “Folks, when I tried on the glasses, it was as though they had been custom-made just for me! I want to thank you for being a part of that!”
The people listened, happy for the amazing glasses. But the director surely must have confused their church with another, they thought, there were no glasses on their list of items to be sent overseas.
But sitting quietly in the back, with tears streaming down his face, an ordinary carpenter realized the Master Carpenter had used him in an extraordinary way.
(  ) 56. Which of the following is NOT true about Grandpa Nybakken according to the passage?
A. He was an outgoing man and held an active attitude towards life.
B. He had a large family to support.
C. He was a carpenter working in the church.

(  ) 57. Grandpa spent much of his time and money in church mainly to ________.

B. help those people in need
C. make some woodwork for the church
D. seek some help from God
(  ) 58. The people in the church but Grandpa felt confused at what the director said because ________.
A. Grandpa didn’t tell the director that he was the owner of the glasses
B. the director wanted to return the glasses even though he liked it
C. the director could not get such glasses in their own country
D. the glasses were not included in the donation list
(  ) 59. Who does “the Master Carpenter” in the last paragraph probably refer to?
A. Grandpa’s master.                   B. One of Grandpa’s friends.  
C. God.                      D. Grandpa’s co-worker.

Then,consider this:you might be in a state of sub-health(亞健康).
Sub-health,also called the third state or gray state,is explained as borderline state between health and disease.

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 trace elements(微量元素)—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.

LEEDS, England—A Leeds University psychology professor is researching a course to help dozens of Britons forgive their enemies.
“The hate we hold within us is a cancer.” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become volunteers in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in each group of eight to ten for a two-hour workshop with a director every two weeks.
The course, ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said, “People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.”
Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidances on how to look at all kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with,” said Norman Claringbull, a senior expert on the forgiveness project.
Hart said, “I believe forgiveness is a skill that can be taught, as these people want to get free of the past.”
小題1:From this passage we know that ________.
A.without hate, people will have less trouble connected with blood pressure and heart disease
B.people who suffer from blood pressure and heart disease must have many enemies
C.high blood pressure can only be cured by psychology professors

小題2:If you are angry with somebody, you should ________.
A.a(chǎn)ttend Hart’s course

小題3:In Hart’s first 20-week workshop, people there can ________.
A.meet their enemies
B.change their attitudes
C.enjoy the professor’s teaching
D.learn how to quarrel with others

A.meet in eight or ten groups

How often do you sit still and do absolutely nothing? The usual answer these days is“never” or “hardly ever”. As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life. There is no way to avoid it, since it takes many and varied forms-driving in traffic, problems with personal relationships are all different forms of stress. Stress, in fact, is not the “baddy” it is often reputed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first sight of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make a choice between “fight” or “fright” and in more primitive days the choice made the difference between life and death. The crisis we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. All the energy is shifted to cope with the stress. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress.
Stress in some people produces stomach disorders, while others experience tension headaches. Since we cannot remove stress from our 1ives, We need to find ways to cope with it.
小題1:People are finding less and less time for relaxing themselves because      .
A.they are working harder than they used to
B.they are often too busy to find the time
C.they are not clear of how to relax by themselves
D.they are suffering from the effects of stress

B.People in primitive days know certain ways to deal with stress.
C.If one gets into the habit of relaxing every day he can overcome stress easily.
D.Stress can lead to serious health problem if one is exposed to it for too long.
小題3:The underlined sentence in Paragraph 2 suggests that      .
A.stress is not always a bad thing for people
B.stress has a bad reputation of causing ill health
C.stress is not so terrible as people often believe it to be

A.Relaxation in life only benefits us mentally.

B.Stress should not be rid completely from the life.
C.Stress produces both positive and negative effects on people.
D.People usually work better under stress if they are healthy.

ASK any group of teenagers in the UK what they most like to eat, and foods like pizzas, curries, pasta, burgers and chips are bound to get a mention – and many young people would probably also list hanging out at the local fast-food restaurant as one of their favorite pastimes.
But what teenagers like to eat is not necessarily what they should be eating. According to the National Diet and Nutrition Survey, far too many young people in the UK between the ages of four and 18 consume too much fat, sugar and salt in their diet and take in too many calories. Meanwhile their intake of starchy carbohydrates (淀粉類碳水化合物), fibre, iron, vitamins and calcium is too low.
For a growing body, eating foods containing plenty of calcium, such as milk, yoghurt and cheese, is particularly important as calcium is essential for the development of healthy, strong bones. Similarly, foods that are rich in iron are good for young, rapidly developing bodies, so red meat, bread, green vegetables, dried fruit and fortified (強化的) breakfast cereals (谷類食物) are also recommended.
It is during our teenage years that lifestyle habits can become entrenched (根深蒂固的), so it is important that young people are educated about what foods are good for them. In 2005, in an attempt to change eating habits and open teenagers’ minds to new flavors and new tastes, celebrity chef Jamie Oliver launched a ‘Feed Me Better’ campaign. As part of a television series, ‘Jamie’s School Dinners’, he worked with teachers and cooks in a number of schools across the UK to provide more healthy, nutritious school meal options. Although the campaign was rather resisted at the beginning, it was generally regarded as a huge success and helped to influence governmental policy on nutritional standards for school meals.
No one expects to end the teenage love affair with fast and junk food but, hopefully, if projects like ‘Feed Me Better’ and the Government's own ‘Change4Life’ campaign continue to give out the right messages, more young people will understand the importance of balancing occasional treats with healthier food options.
小題1:What can we conclude from the first two paragraphs?
A.British teenagers eat too much junk food.
B.British teenagers need to take in more calcium.
C.What British teenagers like to eat is probably what their bodies need
D.British teenagers should reduce their intake of starchy carbohydrates.
小題2:Young people need calcium and iron ______.
A.to improve their brainpower
B.to build healthy strong bodies
C.to provide energy for their body
D.to help change their eating habits
小題3:According to the article, Jamie Oliver launched a campaign at schools to ______.
A.show off his excellent cooking skills
B.teach students how to cook nutritious meals
C.make the public keep an eye on school food
D.improve the children’s diet at school
小題4:Which is a point that the article supports?
A.Teenagers should never eat any junk food at all.
B.It’s easy for children to give up unhealthy eating.
C.It’s okay for a healthy eater to have a little junk food.
D.Once developed, our eating habit will never change.
