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 （肾脏）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 （诊查）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 （糖尿病）and 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．

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 (营养) 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 (蛋白质) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) 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 (寿命).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,_________.

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________.

Scientists now know of a milk-related mutation ( 变异) 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 (腹泻) 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

My secret for staying young is simple. Put all attention to the part of you---your brain and keep it young and growing. Keep your mind awake and you’ll stay young all over. These are exciting time. Take an interest in the world around you, and stick to(坚持) learning at least one new thing every day.
No matter how old you are, it’s not too late to make your life more interesting. I know a housewife with no knowledge before who made herself into a famous industrial engineer(工业工程师).I know a retired(退休) electrical engineer who has became a highly-paid ceramin (陶器的) artist.
Get over the idea that you are ever too old to go back to school. I know a man who entered a medical college at 70.He got his degree with honor and became a doctor. Another man went to law school at 71 and now is an active lawyer(律师).Staying young is easy for those, old or young, who live in the future. You can do it if you care enough to try. Keep you mind awake and active: that’s the only elixir(万验灵丹)
41.The statement that brain to people of all ages, remains young and growing is_____.
A.impossible B.a scientific fact(科学事实)

42.It is wrong to______.
think oneself too old to go back to school B.keep one’s mind awake
try to stay young D.get one’s degree with honors
43.The passage tells that the man who entered college at 70 became_____.
A.an active lawyer B.an electrical engineer

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 (疯狂) 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!

"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 (证明) 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 (法律诉讼),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
