Below is some advice on how to prevent cancer:
8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（结肠） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate（石榴）Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!
4. Take Selenium（硒）
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi（寿司）
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（节省）on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物质） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study. To prevent yourself from catching colon cancer, you should eat ____ as often as possible.
| A．sushi | B．blueberries | C．pomegranates | D．Vitamin D |

_____ will remarkably reduce the risk of men’s prostate cancer.
| A．Having a daily supplement of selenium |
| B．Drinking a cup of pomegranate juice every day |
| C．Breathing fresh air now and then |
| D．Taking exercise at least once a week |
If you want to keep cancer away, it is particularly important to ______.
| A．have a daily supplement of vitamins B and C |
| B．try to ignore the secondhand smoking |
| C．take in as many selenium-containing supplements as possible |
| D．having exercise as often as possible |

Ever since I was a small girl in school, I’ve been aware of what the school textbooks say about Indians. I am an Indian and, naturally, am interested in what the schools teach about natives of this land.
One day, I read that a delicacy(美味) of American Indian people was dried fish, which , according to the textbook, tasted “like an old shoe, or was like chewing on dried leather.” To this day I can remember my surprise, my anger and my sadness at reading these words. We called this wind-dried fish “sleet-shus”, and to us, it was our favorite delicacy and, indeed, did not taste like shoe leather, and didn’t rot our teeth and bring about the various dietary problem that trouble Indian people in modern times. It took many hours of long and hard work to cure the fish in just this particular fashion. Early fur traders and other non-Indians must have agreed, for they often had this food as they traveled around isolated areas.
I brought the textbook home to show it to my father, leader of my tribe at that time. On this particular day, he told me in his wise and modest manner that the outside world did not understand Indian people, and that I should not let it prevent me from learning the good parts of education.
At a later time in my life, I had brought a group of Indian people to the country fairgrounds to sell Indian-made arts and crafts. My group was excited to make some money by selling Indian handicrafts. We thanked the man who showed us to our booth and told him it was nice of him to remember the people of the Indian community. The man expanded a little and remarked that he liked Indian people. “In fact,” he went on to state, “we are bringing some professional Indians to do the show!”
As we stood there in shock, listening to this uninformed outsider, I looked at my dear Indian companion, an eighty-year-old woman who could well remember the great chiefs of the tribe who once owned all the land of this country before the white man came bringing “civilization”, which included diseases and pollution. My friend said not a word, but took the hurt as Indian people have done for many years.
Of course, we all knew that the “professional Indian” were not Indians at all, but dressed in leather and dancing their own dances. And, anyway, how does one become a “professional Indian”?
45．Which of the following statements about “sleet-shus” is true?
A．It tasted like an old shoe.
B．Eating it was like chewing on dried leather.
C．It was delicious but bad for our teeth.
D．It must have brought pleasure to Indians as well as early business men.
46．What does the writer mean by saying “how does one become ‘a professional Indian’”?
A．Only the Indians know how to become professional Indians.
B．The outside civilization can help and Indian become a professional Indian.
C．An Indian is a born professional Indian.
D．The outside civilization can help white people become professional Indians.
47．After reading the passage, you don’t know __________.
A．what the writer’s profession is
B．what upset the writer and her friend at the county fair
C．why the writer went to the county fair
D．the writer’s attitude to the so-called civilization
48．This story is primarily about ___________.
A．customs of native Americans
B．how textbooks describe native Americans.
C．misunderstanding between people from different cultures
D．how an Indian becomes a “professional Indian”

What Is a Boy?
Between the innocence of babyhood and the seriousness of manhood we find a delightful creature called a “boy”. Boys come in different sizes, weights, and colors, but all boys have the same belief: to enjoy every second of every minute of every hour of every day and to fill the air with noise until the adult males pack them off to bed at night．
Boys are found everywhere－on top of, under, inside of, climbing on, swinging from, running around, or jumping to． Mothers spoil them, little girls hate them, older sisters and brothers love them, and God protects them． A boy is TRUTH with dirt on its face, BEAUTY with a cut on its finger, WISDOM with chocolate in its hair, and the HOPE of the future with a snake in its pocket．
When you are busy, a boy is a trouble – maker and a noise． When you want him to make a good impression, his brain turns to jelly or else he becomes a wild creature bent on destroying the world and himself with it．
A boy is a mixture – he has the stomach of a horse, the digestion of stones and sand, the energy of an atomic bomb, the curiosity of a cat, the imagination of a superman, the shyness of a sweet girl, the brave nature of a bull, the violence of a firecracker, but when you ask him to make something, he has five thumbs on each hand．
He likes ice cream, knives, saws, Christmas, comic books, woods, water (in its natural habitat), large animals, Dad, trains, Saturday mornings, and fire engines． He is not much for Sunday schools, company, schools, books without pictures, music lessons, neckties, barbers, girls, overcoats, adults, or bedtime．
Nobody else is so early to rise, or so late to supper． Nobody else gets so much fun out of trees, dogs, and breezes． Nobody else can put into one pocket a rusty knife, a half eaten apple, a three-feet rope, six cents and some unknown things．
A boy is a magical creature – he is your headache but when you come home at night with only destroyed pieces of your hopes and dreams, he can mend them like new with two magic words, “Hi, Dad!”

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means.
Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal’s teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液). A single experience with this kind of plant will teach an animal to stay away from it in the future.
67．The holly plant has more spines on the lower leaves because most animals________.
A．are not tall enough
B．like the lower leaves only
C．are not clever enough
D．can get the lower leaves easily
68．To defend themselves, oak trees use________.
A．chemical means B．physical means
C．bitter chemicals D．sandy materials
69．How does tobacco protect itself against an attack from a caterpillar?
A．Its leaves fight against the attack by physical means.
B．Its roots send a messenger to discourage the caterpillar.
C．Its roots increase the production of nicotine when it is attacked.
D．Its leaves produce poisonous sand to drive the caterpillar away.
70．What would be the best title for this passage?
A．Plants and Animals
B．How Plants Defend Themselves
C．Attacks and Defenses
D．How Animals Eat Plant Leaves
Have you ever had the strange feeling that you were being watched? You turned around and，sure enough，someone was looking right at you!
Parapsychologists(灵学家)say that humans have a natural ability to sense when someone is looking at them．To research whether such a“sixth sense”really exists，Robert Baker，a psychologist(心理学家)at the University of Kentucky，performed two experiments．
In the first one．Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes．The subjects(受试者)were eating，drinking，reading，studying，watching TV，or working at a computer．Baker made sure that the people could not tell that he was sitting behind them during those periods．Later，when he questioned the subjects, almost all of them said they had no sense that someone was staring at them．
For the second experiment，Baker told the subjects that they would be stared at from time to time from behind a two-way mirror in a laboratory setting．The people had to write down when they felt they were being stared at and when they weren’t．Baker found that the subjects were no better at telling when they were stared at and when they weren’t．Baker found that the subjects were no better at telling when they were started at than if they had just guessed．
Baker concludes that people do not have the ability to sense when they’re being stared at．If
people doubt the outcome of his two experiments，said Baker，“I suggest they repeat the
experiments and see for themselves．”
64．The purpose of the two experiments is to．
A．prove why humans have a sixth sense
B．explain when people can have a sixth sense
C．show how people act while being watched in the lab
D．study whether humans can sense when they are stared at
65．In the first experiment，the subjects．
A．were not told that they would be stared at
B．lost their sense when they were stared at
C．were not sure when they would be stared at
D．were uncomfortable when they were stared at
66．What can be learned from the passage?
A．People are born with a sixth sense．
B．People have a sixth sense in public places．
C．The experiments support parapsychologists’ idea．
D．The subjects do not have a sixth sense in the experiments．
We’ve all heard the saying “Go Green”, but is it important? Can one person really make any difference? These may all be questions you’re asking yourself.
Our main source of energy, at the moment, is fossil fuels. We’ve been using fossil fuels for decades now, so why stop? You see, fossil fuels are created over time by the earth, and can only be replaced over time by the earth, but we were using them faster than the earth could produce them. On top of stripping(剥夺)the earth of her natural resources, we’re also damaging the atmosphere by burning things like coal, oil, and natural gases. That’s the greenhouse effect, which occurs when the burning of these fossil fuels help trap the sun’s energy inside the earth’s atmosphere, causing the temperature to rise over time.
With all the people in the world, how could you possibly make a difference? Well, here are a few things to think about.
How many lights do you use in your house?
How many miles do you drive to work?
How many electronics do you use, which you don’t need?
If you were to stop and think about it, you’re able to make a bigger difference than you might realize.
So many times you’ll hear people say, “So what? I won’t be around for it when things go bad.” But bad times are coming quicker than you might like to believe. It’ll be you children, or maybe even your grandchildren. With the temperature ever-rising, the polar ice caps are melting and water begins taking over land, so many people will crowd into so little space.
As you can see, this is no laughing matter. It’s time to take action. Don’t let your children or grandchildren live in a world without hope. One person at a time, we can begin to save this earth.
