Imagine your body is like the house you live in.Every day, your family creates rubbish.The rubbish builds up until it is put out for the weekly garbage collection.
Now, say you put three bags of garbage out.but because one of the collectors was away sick, only two bags are collected.You take the leftover bag inside to be put out again next week.The following week you put on another three bags.plus the leftover bag from last week.But again, only two bags are collected.Imagine this cycle is repeated over the following weeks.
This is a simple description of what happens to your body when your kidneys (腎臟)don't work efficiently.Your body is nol thoroughly emptied of waste products.Other areas of the bodv such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins.
It's not uncommon for people to lose up to 90% of their kidney function before deveoping any symptoms.There may be no warning signs. This makes early detection (診查)difficult.
Kidney's main job is to remote toxins(毒素) and unwanted water from our blood.Every day our kidneys clean an average of 200 litres of blood.Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain.
Research shows that more than 35% of the patients requiring dialysis (透析)do not see a kidney specialist before they have to do so.Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage.Two major risk factors for kidney disease, diabetes (糖尿。゛nd high blood pressure, have been on the rise over the last few decades.Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease.
66.The author gives the example of the house we live in to indicate that ______.
A.it doesn't matter much if the waste in our body is not emptied in time
B.our body will not produce any waste if our kidneys work efficiently
C.it's important for our body to empty the waste in time every day
D.it's safe and harmless for our body to keep some waste
67.The underlined word “insidious” in Paragrap 3 means          .
A.smooth and safe                 B.a(chǎn)pparent and fast
C.gradual and unnoticed       D.long and painful
68.We can infer that when we find some symptoms related to our kidneys,          .
A.the kidney failure begins
B.the kidneys can still work properly
C.we have lost about 10% of kidney function
D.the kidneys may have been seriously damaged
69.How many risk factors of kidney disease are mentioned in the passage?
A.Six.     B.Five.  C.Four.  D.Two.
70.Which of the following helps prevent kidney damage most effectively?
A.Go to see a kidney specialist shortly before dialysis starts.
B.Take enough exercise and make early detection of kidney disease.
C.Try to keep low blood pressure and a stable lifestyle.
D.Go to hospital whenever you find any warning signs.

Ⅲ 閱讀(共兩節(jié)。滿(mǎn)分40分)
第一節(jié)閱讀理解(共15小題;每小題2分,滿(mǎn)分30分)
閱讀下列短文,從每題所給的A、B、C和D項(xiàng)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (營(yíng)養(yǎng)) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白質(zhì)) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (維他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (壽命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
41. According to the passage,_________.
A .we should always keep fit
B. if we were healthy, we could spend our days in doing things with less sleep
C. one can eat a lot to stay in good shape
D. one needn't take any exercise if he is healthy
42. In order to keep good health, ___________ .
A. we should eat a lot of sweets      
B. one needs a large amount of fat
C. people should eat according to the foods nutrition
D. we must try to sleep now and then
43. Eating more and sleeping less________.
A. can keep healthy                 B. is no good for you
C. gets you more energy           D. will keep your personality
44.The writer explains ________in this passage.
A. how to eat                         B. the importance of doing exercise

None of our early ancestors could digest milk as adults because their bodies never had to ----milk drinking simply wasn’t an option. As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives.
Scientists now know of a milk-related mutation ( 變異) in our genes -- the chemical instructions for life that we carry in almost every cell in our bodies. People who have a mutated form of one particular gene can drink milk just fine. People without the mutation tend to get sick from milk.
To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation today. Patterns are striking.
Most adults in Northern and Central Europe are able to digest milk -- and they do. Cheese and butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England. Because European settlers dominated North America, most people here can handle milk just fine, as well. That may explain why ice cream is such a popular dessert in the United States.
In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea (腹瀉) and other stomach problems. (That’s why you won’t typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native
Americans are also unable to digest milk.
Based on these genetic patterns, scientists have long thought that- milk drinking started inNorthern Europe, where dairy is an institution and the milk-digesting mutation is everywhere.
A recent study painted a different picture. With a computer medal, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factor. Working backward, the scientists concluded that the first milk-thinkers lived in Central Europe around what’s now Hungary about 7,500 years ago. The practice didn't start farther north, as scientists had thought before.
66. Which of the following is the proper order of events according to the passage?
a. Their children were able to digest milk as adults.
b. They got sick from the milk.
c. Some people got a mutation in their genes.
d. Some people tried drinking milk from animals.
e. Some people started to drink milk from animals on a regular basis.
A. c→d→b→e→a   B. d→e→b→c→a  C. d →b→e→c→a   D. e→d→b→c→a
67. Most people in the USA can digest milk because __________.
A. they have strong stomachs              B. their ancestors were Europeans
C. that’s where milk drinking stinted       D. farmers raise a lot of cows there
68. Which of the following is LEAST likely to appear on the menu in a Japanese restaurant?
A. Butter.          B. Vinegar.          C. Fish.               D. Beef.
69. Which of the following is the author most likely to agree with?
A. Milk drinking first started in Northern Europe.
B. Milk drinking first started in Central Europe.
C. North American Indians were able to digest milk.
D. Dairy products are very popular in North Korea.
70. The main focus of the scientists' research was ______________.
A. mutation of human genes               B. development of the human stomach
C. why milk drinking started              D. where milk drinking first started

Do you wake up in the morning dreading the moment that your feet have to hit the floor for you to get ready for work? If that’s the case, join most of Americans. Very few people wake up to that annoying alarm clock and spring out of bed excited about having to go to work.
As if that were not enough, most of us have to fight traffic getting there, usually an hour’s drive. Then, when we get to work, we have to fight with unruly co-workers or a nagging boss. And to make matters worse, you have to fight the same traffic going in the opposite direction just to get back home.
Making dinner, fixing plates, eating and then straightening up afterwards is a job within itself. If that sounds like your life, you probably have a J-O-B. you know what J-O-B stands for? Just Over Broke, that’s what! With a job, most Americans are living paycheck-to-paycheck and hating every minute of it. I know because I was doing the same thing: trading time for money. And, I came to a conclusion that it stinks (糟糕透了)! Big time!
Looking around at my co-workers, friends and relatives, I saw that they were all doing the same thing I was doing. They were complaining about the same things I was complaining about : not having enough time or money. And, I decided that I wanted to do something different.
So, I started a home-based business. There are several to choose from. The extra income has done so much for our family. We can vacation more. We have been able to give more. And, we’ve even been able to do something calling save! It’s been amazing.
Therefore, if you’re sick and tired of being sick and tired, it’s time you make a change, too. The definition of insanity (瘋狂) is doing the same thing over and over and expecting different results. I know you aren’t stupid. If you continue to do what everyone else is doing: trading time for money, you’re going to keep getting what everyone else is getting: being broke and not having the time to do what is really important to you.
Do your due diligence. Find a home-based business that works well for you. Go to work, and live the life you’ve always imagined!
小題1:According to Paragraph 1, which of the following statements is TRUE about most Americans?
A.Most Americans are excited to go to work every day.
B.Most Americans are used to sleeping in the morning.
C.Most Americans are tired of having to go to work every morning.
D.Most Americans have alarm clocks to wake them up in the morning.

A.Regret.B.Joy.C.Pride.D.Dissatisfaction
小題3:What does “something different” in Paragraph 4 refer to?
A.To set up a business at home.B.To complain about life and work.

D        
"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 new shapes and new looks 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 to 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 and Drug Administration )can require proof (證明) under the Food, Drug, and Cosmetic Act that 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 it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律訴訟),and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
71. It can be inferred that the ads mentioned in the text are        .
A. objective    B. costly    C. unreliable    D. illegal
72. 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.
73. FDA can ask for the proof of safety and effectiveness of a product        .
A. if it is a drug      
B. if it is a device
C. if its consumers make complaints
D. if its distributors challenge FDA's authority
74. 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
75. The author intends to        .
A. make consumers aware of the promoters' false promises
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

Apparently,we are safe neither at home nor in the business office.We use water in both places,but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap,spraying from garden pipes,or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通風(fēng)), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”
64.What is the main idea of the first paragraph?
A.The air we breathe in is harmful.
B.The water in everyday use is unsafe.
C.Chemicals are added to the drinking water.
D.Chemicals are released in the running water.
65.In Paragraph 2, the underlined sentence means that       .
A.bathing should be done with caution
B.homes and offices should be aired often
C.a(chǎn)ny pollution should be taken into consideration
D.we should prevent any pollution from doing harm to us
66.What is the purpose of the passage?
A.To call on us to guard our water.
B.To show us that no place is like home.
C.To make us aware of the pollution around us.
D.To argue that neither homes nor offices are safe.

D
The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government's health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.
In addition, health education plays a key role in improving people's health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one's family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.
However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
67.What’s the best title of the passage?
A.Prevention or Education?    B.Prevention or Treatment?
C.Health or Illness?            D.Exercise or Illness?
68.Which of the following can replace the underlined word “bankrupt’’?
A.Unable to be cured        B.Unable to pay one’s debts
C.Stronger than ever before  D.More successful than ever before
69.We learn from the passage that       .
A.dressing warmly can prevent diseases
B.a(chǎn) balanced diet is cheaper than regular exercise
C.the more health education, the better
D.the government’s health budget should be increased

Foods from Around the World
Foods that are well known to you may not be familiar to people from other countries. Here are four people’s experiences with foreign food.
Shao Wong is a student in France. He comes from China. “I’d never tasted cheese or even milk before I came here. Cattle are rare in my part of China, so there are no dairy products. I tried milk when I first arrived in France. I hated it! I sampled cheese too, but couldn’t manage more than one bite. I love ice cream, though, and that’s made from milk.”
Birgit is from Sweden. She traveled to Australia on vacation. “I was in a restaurant that specialized in fish, and I heard some other customers order flake. So I ordered some too and it was delicious. Later, I found out that flake is an Australian term for shark. After that pleasant experience, whenever I see a new food I try it out on purpose. You know why? I remember how much I enjoyed flake.”
Chandra is a dentist in Texas. She originates from India. “I’m frightened of eating new foods because they might be made from beef. I’m a Hindu, and my religion forbids me to eat meat from the cow. It’s a sacred animal to Hindus, so that’s the reason I can’t eat hamburgers or spaghetti with meatballs.”
Nathan is American. He taught for a year in China. “My friends gave me some 100-year-old eggs to eat. I didn’t like the look of them at all. The insides were green, but my friends said the color was normal. The Chinese put chemicals on fresh eggs. Then they bury them in the earth for three months. So the eggs weren’t really very old. Even so, I absolutely refused to touch them.”
Life in a new country can be scary, but it also can be fun. Would you sample a 100-year-old egg? Would you order shark in a restaurant?
56. Which of the following sentences is true about Shao Wong?
A. He is a French – Chinese.
B. Cattle are seldom raised in his hometown.
C. He doesn’t like any diary products.
D. He didn’t taste cheese because he hated it.

A. It’s against Hindus’ religion.
B. She is a doctor and she thinks beef is not easy to chew and digest.
C. She is an Indian.
D. Hindus think beef is not tasty.
59. The underlined word “Sacred” in paragraph 4 means _________.
A. frightening  B. large    C. man – eating        D.greatly respected
60. What can you infer from this passage?
A. Foods that are well known to you may not be familiar to people from other countries.
B. Despite (雖然) cultural differences in food, have a try and maybe you’ll get used to it.
C. A vacation is a good way to learn about new foods. Be sure to go on vacation more   often.
D. People dislike eating new foods only because their religion forbids it.
