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.

2.A person is very likely to catch some type of cancer if ______.

Now let us look at how we read. When we read a printed text, our eyes move across a page in short, jerky (急动的)movement. We recognize words usually when our eyes are still when they fixate. Each time they fixate, we see a group of words. This is known as the recognition span(范围)or the visual span. The length of time of which the eyes stop ---the duration of the fixation (定位)----varies considerably from person to person. It also varies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness.

  Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive (连续的) fixation. All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently (因此), for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated (孤立的) words and phrases would seem unlikely to help him in reading a continuous text.

1.The time of the recognition span can be affected by the following facts except ________ .

A.one’s familiarity with the text

B.one’s purpose in reading

C.the length of a group of words

D.lighting and tiredness

2.The author may believe that reading ______.

A.requires a reader to take in more words at each fixation

B.requires a reader to see words more quickly

C.demands an deeply-participating mind

D.demands more mind than eyes

3.What does the author mean by saying “but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently.” in the second paragraph?

A.The ability to see words is not needed when an efficient reading is conducted.

B.The reading exercises mentioned can’t help to improve both the ability to see and to comprehend words.

C.The reading exercises mentioned can’t help to improve an efficient reading.

D.The reading exercises mentioned has done a great job to improve one’s ability to see words.

4.Which of the following is NOT true?

A.The visual span is a word or a group of words we see each time.

B.Many experts began to question the efficiency of eye training.

C.The emphasis on the purely visual aspects is misleading.

D.The eye training will help readers in reading a continuous text.

5.The tune of the author in writing this article is ________

A.critical (批评的)

B.neutral (中立的)

C. pessimistic (悲观的 )

D.optimistic

Ever since I was little I loved doing things for other people. As I got older I began doing random ( 随意的 ) things for people. For example, during holidays, such as Christmas, I would make an extra   21  along with the ones for my relatives. Then I would go and find someone in the grocery store and just hand it to them and walk away. It was so much fun. I admit,   22 , the first time I did it I was so   23 . I didn’t know who to give the card to. So I said a little prayer and knew that the   24  person would just appear. About that time an elderly man ran   25  me with his shopping cart. It was an accident, and he   26  a million times. We smiled and he walked away, and I knew that he was the one.  Later I found him in a different isle(过道), handed him the card, and smiled. I said Happy Holidays, and then walked away. It was so great, and the   27  I had afterwards was unexplainable.

Then one day I came across your website (the coolest website ever) and   28  some Smile Cards. When they came in, I started a new project. When I go into a store, I locate a person who I think needs a   29 . Then, I buy a flower, a carnation, to be exact, and   30  it in the most beautiful paper they have. I tie lots of ribbons on it to make it   31 , and then slip the smile card into an envelope and   32  it to the flower. After that, I pay for it and explain to the cashier   33  it is to go to (I live in a pretty small town so it’s easy to get the help of the cashiers). They then give it to that person when they come through.. Once in a while I’ll buy the flower and then just leave it for the cashier. That gets smiles.

My favorite time was when I picked out this elderly woman who was walking around the   34  somewhat confused. I had come across her numerous times and she only smiled slightly once. When she came to the check out (I was watching from outside) her face   35  and the smile was the biggest I had ever seen. Later that week the cashier whom I had had   36  me told me that the lady had been so surprised and while she was walking out with the grocery bag to her car, she was planning what she was going to do for someone else. It was awesome.

I absolutely love the random acts of kindness cards. I   37  at least two in my purse and others in my car, locker and everywhere I go. As I mentioned, my club, STARS, is doing a Random Acts of Kindness Project with the smile cards so they also are using them. I look forward to hearing about their success. It’s really great. I   38  used them in school. I bought my entire math class cans of pop after lunch one day. They came in from lunch and a can of pop and a smile card were setting   39  that day. It totally lightened the mood in the class that day   40  we were studying for a test. Thank you for all of the help that you provide. The smile cards are a great program that brings smiles into the lives of many!
