American farmers are raising five percent more goats for meat these days.
Goat meat is high in protein(蛋白質(zhì))and lower in unhealthy fat than many other meats.Even so,the industry is small compared to chicken,beef and pork. But immigration has brought more of a taste for goat to America from all over the world.
Experts from the University of Illinois offer some questions for people to consider if they are thinking about raising goats.
First of all,do you understand that there always has to be someone to care for the goats?
◆How much land do you have available? And how good is it? Poor ground may support two to four goats on half a hectare.Better grassland can support six to eight. If goats and cattle share the land,two goats can be added for each cow. The goats will eat weeds and other plants that cattle do not like.
◆Do you have buildings for the number of female goats you plan to keep during winter? An open,cold,dry barn is better than a closed,warm barn where the air is wet.
◆Do you have the equipment to clean barns(畜棚) and to harvest hay(草料) to feed your goats? Or will you get someone else to do it,or buy the hay?
The experts say a profitable business in goat meat may take three to five years to establish.And, of course, there are no guarantees .
小題1:On which section of a newspaper will this passage appear?
A.International AffairsB.Entertainment
C.AgricultureD.Culture
小題2:Which of the following is NOT a factor in making goat meat more popular?
A.Goat meat is healthy food.
B.Immigrants bring different tastes.
C.The industry still leaves room for profit.
D.Raising goats is challenging.
小題3:If someone has two hectares of good grass land, what is the maximum number of cows and goats he can raise?
A.32 cows and 64 goats.B.32 cows and 32 goats.
C.16 cows and 32 goats.D.8 cows and 16 goats.
小題4: What is the experts’ opinion about the goat-raising business?
A.You can make sure money.
B.You had better be cautious and patient.
C.Goats are hardly possible to raise.
D.Goat meat still needs to be recognized.

Have you ever been in a situation, where you felt uneasy because of something you think you may have forgotten to do or perhaps a feeling that you annoyed someone whom you wanted to get along with really well. If you have experienced such feelings and worse on a regular basis, then you most probably are a victim of anxiety attacks.
All of us, to some extent, have experienced anxiety at different levels. There are somethings you may know about anxiety, and some things that you may not be familiar with. So in order to be prepared for your unexpected feeling of anxiety, you need to get to know what anxiety is before it escalates into a panic attack.
Anxiety is simply the feeling of discomfort, uneasiness or fear of what may eventually happen resulting from an imagined, or a real threatening condition. On the extreme end panic attacks can occur due to heightened(增加) feelings of anxiety.
There are two main symptoms(癥狀) during an anxiety / panic attack and these are physical and emotional symptoms. Physical symptoms include difficulty in breathing, shaking, direct feeling of heat, rapid heartbeat and tiredness while emotional symptoms deal with worrying, depression, fear, and lack of focus.
In spite of the negative impression we have for anxiety, it is not dangerous in any way whatever. The feeling of anxiety is not bad, in fact it’s more of a defensive feeling which protects us from possible danger by engaging a response within us in fight or fight situations. So it’s not the “bad guy”, you just have to learn how to control it. Panic attacks, however, are far more dangerous and should be a concern to your health. Panic can sometimes result in blurred (模糊不清的) vision, difficulty in breathing due to a tight chest. The best way to different anxiety from any serious illness is to ask a medical expert for advice on a regular basis.
小題1:According to the passage, a panic attack is _______________.
A.a(chǎn)s serious as an anxiety attackB.not so serious as an anxiety attack

B.he has trouble in hearing and vision
C.he is always worried about others
D.he can’t pay attention to what he does
小題4:From the passage we can draw a conclusion that ______________.
A.a(chǎn)n anxiety attack does good to usB.a(chǎn)n anxiety attack does no harm to us
C.a(chǎn)n anxiety attack is a serious illnessD.a(chǎn)n anxiety attack is very dangerous
小題5: What is the best title for this passage?

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
  An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted(傳播)by a germ(病菌). He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.
  Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
  Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice(糙米)somehow prevented or cured beri-beri — even that a lack of some ingredient(成分)in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.
小題1:According to the passage, a good mixed diet ________.
A.is suitable for losing weightB.should be only fruits and vegetables
C.normally contains enough vitaminsD.is often difficult to arrange
小題2:What do we know about the disease beri-beri?
A.It killed large numbers of people.B.It resulted from lack of vitamins.
C.It was transmitted by milled rice.D.It was caused by diseased chickens.
小題3:What can be the best title of the passage?
A.A Good Mixed Diet       B.New Discovery
C.The Dangers of Beri-beri     D.The Importance of Vitamins

The gray-haired lady can’t wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.
Not all cases of Alzheimer’s disease look like this, but Alzheimer’s is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer’s. In the early stages, people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs.
While no one is certain what causes these changes in the brain’s nerve fibers (神經(jīng)纖維), their effect is certain. Alzheimer’s destroys not only the patients, but also spouses(配偶), friends and families.
What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer’s disease. Though many reasons other than Alzheimer’s disease may cause memory loss, its early diagnosis(診斷)and treatment may delay some of the most serious effects.
What feeling will you likely experience if a loved one suffers from Alzheimer’s disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn’t remember you are married.
Life for the Alzheimer’s patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.
小題1:What can be inferred from the passage about the gray-haired day?
A.She has been living with her father.
B.She was sad about the death of her father.
C.She can’t search for her father without being watched.
D.She suffers from Alzheimer’s disease.
小題2:When people suffer from Alzheimer’s disease, ________.
A.their families and friends will suffer from the same disease
B.their families and friends will experience mental sufferings
C.they will certainly die in 8 to 10 years
D.they will forget everybody but their spouses
小題3:Memory loss occurs ________.
A.from Alzheimer’s disease and nothing else
B.from sadness, shock, anger, and so on
C.for a number of reasons
D.with changes in personality
小題4:From the passage we know that        .
A.early treatment may stop Alzheimer’s disease occurring
B.it is still unknown what causes the changes in the brain’s nerve fibers
C.nerve fibers in the brain will cause Alzheimer’s disease

Our spiritual intelligence quotient (精神智商),or SQ, helps us understand ourselves, and live fuller, happier lives.
Though we're all born with SQ, most of us don’t even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.
Sit Quietly. The process of developing spiritual intelligence begins with solitude (獨(dú)處) and silence. To tune in to your spirit, you have to turn down the volume (強(qiáng)度) in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.
Step Outside.  For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flower in bloom; follow the light of a bird and watch clouds float overhead.
Ask Questions of Yourself. Ask open-ended questions, such as "What am I feeling? What are my choices? Where am I heading?"
But don't expect an answer to arrive through some supernatural form of e-mail. "Rarely do I get an immediate answer to my question," says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. “But later that day I suddenly find myself thinking about a problem in a perspective(角度) I never considered before.”
Trust Your Spirit. While most of us rely on gut(本能的) feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.
68. The passage is mainly about           .
A. what your SQ is and in what way it can benefit our life
B. what your SQ is and in what way it can be improved
C. the relationship between your SQ and your life
D. advantages and disadvantages of SQ
69. The underlined phrase "tune in to your spirit" in the third paragraph probably means to _____.
A. get your spirit relaxed                   B. keep up your spirit
C. keep seated quietly                      D. change your spirit
70. The author mentions the example of Reverend Joan Carter to show that            .
A. there are no immediate answers to your questions
B. e-mails can't keep working out a problem
C. the more questions you ask, the better answers you'll get      
D. changing your way of thinking might help you solve a problem
71. From the passage, we can know that the most important thing to improve your SQ is      .
A. a peaceful mind    B. deep thought   C. spare time and hobbies   D. good spirits

Air travel is such an everyday experience these days that we are not surprised when we read about a politician having talks with the Japanese Prime Minister one day, attending a meeting in Australia the following morning and having to be off at midday to sign a trade agreement in Hong Kong. But frequent long-distance flying can be so tiring that the traveler begins to feel his brain is in one country, his digestion(消化吸收)in another and his powers of concentration nowhere---in short, he hardly knows where he is.
Air travel is so quick nowadays that we can leave London after breakfast and be in New York in eight hours, yet what really upsets us most is that when we arrive it is lunch time while we have already had lunch on the plane and are expecting dinner.

People today expect to be examined when they enter a doctor's office. At least they expect their blood pressure and temperature to be measured. However, as recently as two hundred years ago, a doctor's treatment depended on talking with patients. In general, the communication between doctors and their patients was the most important part of medical methods. The modem age of medicine began with the stethoscope ,an instrument for listening to patients heartbeat and breathing. Before that, a doctor did not touch a patient. In fact, there was no such things as a medical examination.
The stethoscope──and all other medical instruments──-had a serious effect, on the practice of medicine. Doctors became better at finding the medical problems. More lives were saved. At the same time, doctors gave less importance to the communication between patients and doctors. Some doctors actually stopped talking to their patients. It is easy to understand why some sick people thought themselves as broken machines.

Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday. In a small study, the researchers tracked 30 men with low-risk prostate cancer(前列腺癌)who decided against conventional medical treatment such as surgery and radiation or hormone therapy.  
The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation(冥想). As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes. After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences.
The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health. "It's an exciting finding because so often people say, 'Oh, it's all in my genes, what can I do?' Well, it turns out you may be able to do a lot," Ornish, who is also connected with the University of California, San Francisco, said in a telephone interview. "'In just three months, I can change hundreds of my genes simply by changing what I eat and how I live'. That's pretty exciting," Ornish said. "The implications of our study are not limited to men with prostate cancer."  
60. The article basically states that a healthy lifestyle__________.  
A. can even change your genes for the better.  
B. has no effect on your genes.  
C. is good for the environment.  
D. helps men recover from prostate cancer.  
61. Apart from eating healthy food and exercising, the men in the study__________.
A. were put under a lot of stress.  
B. were walking for hours a day..  
C. were taught stress management methods.  
D. were thinking for a whole day.
62. In total, how many disease-preventing genes turned on as a result of the healthy lifestyle?
A.   30           B. 453                   C.500             D. 48
63. Which of the following is NOT mentioned in the article?
A. The men with low-risk prostate in the study lost weight and lowered their blood pressure.
B. A famous author and Dr. Dean Ornish led this research.
C. Dr. Dean Ornish expressed his optimism about this research in a telephone interview.
D. Conventional medical treatment has no effect on the men with prostate cancer.

D
Will it matter if you don’t take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to what many people believe, if you don’t eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.
77. The results of the test show that ______
A. breakfast has great effect on work and studies.
B. breakfast has much to do with people’s health.
C. a person will work better if he has simple breakfast
D. breakfast only affects those who work with their brains.
78. The passage mentions that many people believe that if you don’t eat breakfast, you will____.
A. not lose weight                                             B. be healthier
C. gain weight                                              D. lose weight  
79. We can infer from the passage that _____
A. one can work better without breakfast.
B. morning diet will do good to your health.
C. reducing lunch and supper will help lose weight.
D. breakfast is more important than lunch and supper.  
80. What is the best title for this passage?
