The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives, which we eat, are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

Bacteria(细菌) are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in micron. One micron is a thousandth of a millimeter; a pinhead is about a millimeter across, Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron across. Thus, if you magnified a rounded bacterium a thousand times, it would be just the size of a pinhead, while a grown-up human enlarged by the same amount would be over a mile tall.
Even with an ordinary microscope(显微镜), you must look closely to see bacteria. Using a magnification of 100 times, one can hardly find bacteria. Nor can one make out anything of their structure(结构), of course. Only by using special colors, can one see that some bacteria have wavy-looking “hairs” called flagella. Others have only one flagellum. The flagella move round a central point, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can move along over surface by some little-understood “machinery”.
From the bacterial point of view, the world is a very different place from what it is to humans. To a bacterium, water is as thick as molasses(糖浆) is to us. Bacteria are so small that they are affected by the movements of the chemical molecules(分子) around them. Bacteria under microscopes, even those with no flagella, often jump up and down in the water. This is because they knock with the water molecules and are pushed this way and that.
36. The underlined word magnified means _______________.
A. enlarged                                                      B. widened                  
C. killed                                                          D. caught
37. We know from the passage that _______________ is the smallest.
A. a pinhead                                            B. a rounded bacterium 
C. a microscope                                        D. a rod-shaped bacterium
38. The relationship between a bacterium and its flagella is most nearly like which of the following?
A. A rider jumping on a horse back 
B. A ball being hit by a bet
C. A boat powered by a motor    
D. A door closed by wind
39. Why does the writer compares water to molasses in the third paragraph?
A. To tell us how difficult it is for bacteria to move through water.
B. To suggest that bacteria are fond of different liquids.
C. To show different chemicals are of different structures.
D. To show that bacteria are the best swimmers.
40. Which of the following is the main topic of the passage?
A. The characteristic (特点) of bacteria.      
B. How bacteria reproduce.
C. The various parts of a bacterium’s body    
D. How bacteria cause diseases.            
Your chair is your enemy. That is the conclusion of several recent studies. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don’t.
So what’s wrong with sitting? The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.
You may think you have no choice about how much you sit. But this isn’t true. Suppose you sleep for eight hours each day, and exercise for one. That still leaves 15 hours of activities. Even if you exercise, most of the energy you burn will be burnt during these 15 hours, so weight gain is often the cumulative(累积的) effect of a series of small decisions: Do you take the stairs or the elevator? Do you walk to the corner store, or drive?
But it looks as though there’s a more sinister aspect to sitting. Some evidence suggests that when you spend long periods sitting, your body actually does things that are bad for you.
Lipoprotein lipase(蛋白脂酶) is a molecule that plays a central role in how the body processes fats. Low levels of lipoprotein lipase are associated with a variety of health problems. Studies in rats show that leg muscles only produce this molecule when they are actively being moved. The result is that when you sit, an important part of your metabolism(新陈代谢) slows down. You may also have a higher risk of suffering from diabetes(糖尿病).
Some people have advanced radical solutions to the sitting syndrome(综合症): replace your sit-down desk with a stand-up desk, or watch television in a rocking chair. But whatever you choose, know this. The data is clear; look out for your chair.
小题1:What would be the best title of this passage?
A.Become an Athlete to Be Healthy.
B.Choose a Better Chair for You.
C.How to Speed Up Your Metabolism.
D.Stand Up While You Read This.

A.taking too much exercise harms people’s health
B.sitting a lot reduces the benefits of taking exercise
C.people needn’t depend on exercise to keep healthy
D.healthy people are those who sit less and stand more
小题3:Which of the following is the best advice on how to control our weight?
A.Exercising at least an hour a day.
B.Standing as long as possible.
C.Using our energy actively in daily life.
D.watching TV in a rocking chair.

Who says Americans worship the almighty dollar? It’s not true.Having enough free time is more important to most Americans than being rich, according to a new poll.
Only 13 percent of more than 2,400 people questioned in the telephone poll ranked being wealthy as most important to them, while 67 percent ranked free time as their top priority, higher than having a successful career, getting married, and having children."Everyone wants free time to do the things they want to do, young, middle-aged or old," said Richard Morin, of the Pew Social & Demographic Trends Project, which conducted the survey."So our desire to play unites us."
The poll also showed that people who were university educated valued career success over wealth, as middle-aged people did.Not surprisingly, those who didn't have money, ranked wealth very highly.This included minorities, first generation Americans and less educated people.The survey also revealed that a disproportionate (不成比例的) number of people under the age of 30 and retirees in the group made $ 20,000 or less a year.But the emphasis on wealth lessens with age, with younger people putting value on it but hardly any seniors."It just diminishes with time as the reality sets in that you would never be rich," Morin said."But also, the reality sets in that you don't have to be rich to lead a very comfortable and fulfilling life."
While wealth was not at the top of people' s list of priorities, 43 percent still said it was somewhat important.
56.The poll showed that the majority of American people ranked ____ as the most important.
A.wealth              B.a successful career 
C.marriage            D.free time
57.Who cares least for wealth, according to the passage?
A.Young people.                    B.Middle-aged people.
C.Old people.                       D.Well-educated people.
58.The underlined word "diminishes" in the third paragraph probably means "____".
A.to increase          B.to decrease          C.to change          D.to stay

Show Your Bones is the newest album from a musical group with an unusual name, the Yeah Yeah Yeahs. The energetic music made by these rock musicians is becoming very popular in America.
A singer, a guitar player and a drummer make up the Yeah Yeah Yeahs. Their rock sound is creative, unusual, and full of personality. Their music is considered an example of “indie”(short for independent) rock. Indie musicians like to protect their independence and artistic freedom. One way to do this is to avoid using major record companies. The lead singer Karen O is known for wearing wild clothing and having wild hairstyles while performing. Sometimes she even pours beer over herself and the audience. Imagine Karen O dancing around on stage as you listen to her sing the song, Phenomena.
The words in the songs on Show Your Bones are poetic and also a little strange. It is not always clear what the songs mean. In the song called The Sweets, Karen O describes colors and the motion of water. Also, she wonders about meeting someone again.
The Yeah Yeah Yeahs started playing music together in New York City.
Now Karen O has moved to Los Angeles, California. She says that she likes flying between the two cities and the band is now “bi-coastal”. Karen O also said that this album was the most difficult to make. The band was trying to find a different sound from their earlier albums. Their work seems to have been worth the effort. Critics say Show Your Bones might be one of the best albums of the year.
39. How many people are there in the Yeah Yeah Yeahs?
A. Two.       B.One.    C. Four.    D. Three.

I have a close friend who has a good family tradition, that is, each year after Thanksgiving dinner, all of the people sit around in the living room and each person takes a few minutes and gives thanks for what really matters and what has added value to their life over the last year. This is something I valued and followed. I have thought about a lot in the last year, and I finally came up with two things.
The first one is the healthiness of my daughter. She’s as healthy as she can be, and her weight and height are in good condition and she has no illnesses or genetic diseases. I am so thankful for having this wonderful baby in my life, and thankful that she has the gift of good health.
Secondly, I am thankful for the discovery of the value of writing in my life. A year ago, my website. The simple Dollar was only a few weeks old and was far from popular, but on Thanksgiving Day Last year it had about three score readers who ordered it in advance. The process of writing was bringing me enjoyment, but I hadn’t yet realized that I could be successful in it and attract many readers. This past year showed me a lot and I am deeply thankful for it.
After thinking for a while, I began to realize that it was a very powerful and wonderful positive exercise. You spend time reflecting deeply on the positive things in your life, and you often realize that even when things are bad, you do have a lot to be thankful for because there is lots of good in your life, and it can shine a bright light even in a dark spot in your life.

The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.?
A multitude of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.
68.The concept of personal choice concerning health is important because ____.
A.personal health choice helps cure most illness
B.it helps raise the level of our medical knowledge
C.it is essential to personal freedom in American society
D.wrong decisions could lead to poor health
69.To “live a completely sedentary life style”(L7,Para.1)in the passage means____.
A.to “live an inactive life”    B.to “live a decent life”
C.to “live a life with complete freedom”     D.to “live a life of vice”
70.Sound personal health choice is often difficult to make because ____. ?
A.current medical knowledge is still insufficient
B.there are many factors influencing our decisions
C.few people are willing to trade the quality of life for the quantity of life
D.people are usually influenced by the behavior of their friends

For 52 years my father got up at 5:30 am every morning, went to work, and returned home at 5:30 pm. I never saw my father stayed home from work ill, nor did I ever see my father lay down to take a nap. He had no hobbies, other than taking care of his family. All he asked from me, his daughter, was to help him while he was repairing something, so we could have some time to talk.
For 22 years, after I left home for college, my father called me at 9:00 am every Sunday. Nine years ago when I bought my first house, my father, 67 years old, spent eight hours a day for three days in the 80-degree Kansas heat, painting my house. He would not allow me to pay someone to have it done. All he asked for was a glass of iced tea. Five years ago, at age 71, my father spent five hours putting together a swing set for my daughter. Four years ago, my father drove all the way from Denver to Topeka, with an eight-foot Colorado Blue Spruce (云杉) in his truck, so that we could have a part of Colorado growing on our land.
On the morning of January 16, 1996, my sister telephoned me; my father was in the hospital with an aneurysm(动脉瘤) in Florida. I got on an airplane immediately, and on the way I realized that I hadn’t communicated with him as much as I’d always wanted to. I vowed(发誓) that when I arrived, I would have a long talk with him. I arrived in Florida at 1 am, only to find that my father, at the age of 76, had passed away at 9:12 pm. This time it was he who did not have time to talk, or time to wait for me.

Sports medicine experts have observed for  years that athletes such as long distance runners, especially women athletes, often display a lack of iron. Now a new study by a team of Purdue University researchers suggests that even moderate exercise may lead to reduced iron in the blood of women.   
"We found that women who were normally inactive and then started a program of moderate exercise of middle degree showed sings of iron loss," says Roseanne M. Lyle, associate professor at Purdue. Her study of 62 formerly inactive women who began exercising three times a week for six months was published in the journal Medicine & Science in Sports & Exercise.
Iron deficiency is very common among women in general, affecting one in four female teenagers and one in five women aged 18 to 45, respectively. But the ratio is even greater among active women, affecting up to 80 percent of female endurance athletes. This means, Lyle says, that "too many women ignore the amount of iron they take in". Women of child-bearing age are at greatest risk, since their monthly bleeding is a major source of iron loss. Plus, many health-conscious women increase their risk by rejecting red meat, which contains the most easily absorbed form of iron. And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, and are liable to experience a deficiency.
Exercise can result in iron loss through a variety of mechanisms. Some iron is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system. Athletes in high-impact sports such as running may also lose iron through a phenomenon where small blood vessels in the feet leak blood.
There are three stages of iron deficiency. The first and most common is having low iron reserves, a condition that typically has no symptoms. Fatigue and poor performance may begin to appear in the second stage of deficiency, when not enough iron is present to form the molecules(分子) of blood protein that transport oxygen to the working muscles. In the third and final stage, people often feel weak, tired, and out of breath - and exercise performance is severely compromised.
"People think that if they're not at the third stage, nothing is wrong, but that's not true," says John L. Beard, who helped design the Purdue study. "You're not stage 3 until your iron reserves go to zero, and if you wait until that point, you're in trouble."
Beard and other experts say it’s advisable for people to have a yearly blood test. If iron levels are low, talk with a physician to see if the deficiency should be corrected by changing your diet and taking iron-rich foods or by taking iron-added pills.
“Select breads and cereals with the words ‘iron-added’ on the label,” writes sports diet expert Nancy Clark. “This added iron supplements the small amount that naturally occurs in grains.” Clark also recommends cooking in iron pans, as food can obtain iron from the pan during the cooking process.
64.Which of the following may be the title for the passage?
A.Science, sports and exercise
B.Correct iron deficiency
C.Women, Iron and exercise
D.Women, health and exercise
65.The third paragraph is developed mainly by________ .

A.Nothing serious though you don’t have much iron stored in the body.
B.There is not enough iron to form the molecules of blood protein to transport oxygen.
C.The small blood vessels in your reet are beginnig to leak blood.
D.No iron is left in your body and you would be in trouble without urgent measures.
