Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday. In a small study, the researchers tracked 30 men with low-risk prostate cancer（前列腺癌）who decided against conventional medical treatment such as surgery and radiation or hormone therapy.
The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation（冥想）. As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes. After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences.
The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health. "It's an exciting finding because so often people say, 'Oh, it's all in my genes, what can I do?' Well, it turns out you may be able to do a lot," Ornish, who is also connected with the University of California, San Francisco, said in a telephone interview. "'In just three months, I can change hundreds of my genes simply by changing what I eat and how I live'. That's pretty exciting," Ornish said. "The implications of our study are not limited to men with prostate cancer."
60. The article basically states that a healthy lifestyle__________.
A. can even change your genes for the better.
B. has no effect on your genes.
C. is good for the environment.
D. helps men recover from prostate cancer.
61. Apart from eating healthy food and exercising, the men in the study__________.
A. were put under a lot of stress.
B. were walking for hours a day..
C. were taught stress management methods.
D. were thinking for a whole day.
62. In total, how many disease-preventing genes turned on as a result of the healthy lifestyle?
A. 30 B. 453 C.500 D. 48
63. Which of the following is NOT mentioned in the article?
A. The men with low-risk prostate in the study lost weight and lowered their blood pressure.
B. A famous author and Dr. Dean Ornish led this research.
C. Dr. Dean Ornish expressed his optimism about this research in a telephone interview.
D. Conventional medical treatment has no effect on the men with prostate cancer.

Come prepared: When you arrive at a race, your bike should be in race-ready condition.
Chain Management: Chain damage is still the number one problem with mountain bikes. Keeping your chain clean and well-oiled will help, as will frequent chain replacement. Periodic inspection of your chain for wear, stretch and damage may save you a long walk home.
Packing Tape: This can be used for rims trips, boots for fractured tires and a dozen more makeshift repairs. If you've flown to the race, it also saves you from having to borrow tape to close up your bike box for the flight home. Other musts: safety pins and plastic zip ties.
Pre-race: Visual inspections before any serious off-road ride, carefully examine the area where the tire hooks onto the rim and remove any foreign objects which could cause premature（比预期早的）tire wear.
Tire Pressure: Check tire pressure before race start. The recommended pressure is noted on the tire sidewall, usually 40 lbs., many racers run 50 lbs., or more for less rolling resistance.
Be Self-Contained: Make sure you are self-contained. Bring your own drinking water, food and first aid kit. Also have tools, spare parts, tubes, quick fills and a chain tool. Never suppose you can just borrow these items from a friend.
Post-race Visual Inspections: Inspect your bike after completing each event, especially before competing in a downhill event. Re-inspect before packing your bike for the trip home.
Have Fun!

For several days I saw little of Mr. Rochester. In the morning he seemed very busy with business，and in the afternoon gentlemen from the neighborhood called and sometimes stayed to dine with him. When his foot was well enough，he rode out a great deal.
During this time，all my knowledge of him was limited to occasional meetings about the house，when he would sometimes pass me coldly， and sometimes bow and smile. His changes of manner did not offend me, because I saw that I had nothing to do with the cause of them.
One evening，several days later，I was invited to talk to Mr. Rochester after dinner. He was sitting in his armchair，and looked not quite so severe，and much less gloomy. There was a smile on his lips, and his eyes were bright，probably with wine. As I was looking at him，he suddenly turned, and asked me，“Do you think I am handsome，Miss Eyre? ”
The answer somehow slipped from my tongue before I realized it: “No，sir.” “Ah，you really are unusual! You are a quiet， serious little person， but you can be almost rude.” “Sir，I'm sorry. I should have said that beauty doesn't matter，or something like that,” “No，you shouldn't! I see，you criticize my appearance，and then you stab (刺) me in the back! You have honesty and feeling. There are not many girls like you. But perhaps I go too fast. Perhaps you have awful faults to counterbalance (抵消) your few good points.”
I thought to myself that he might have too. He seemed to read my mind，and said quickly，“Yes，you're right. I have plenty of faults. I went the wrong way when I was twenty-one，and have never found the right path again. I might have been very different. I might have been as good as you, and perhaps wiser. I am not a bad man，take my word for it，but I have done wrong. It wasn't my character，but circumstances which were to blame. Why do I tell you all this? Because you're the sort of person people tell their problems and secrets to, because you're sympathetic and give them hope.”
It seemed he had quite a lot to talk to me. He didn't seem to like to finish the talk quickly，as was the case for the first time.
“Don't be afraid of me， Miss. Eyre，”he continued. “You don't relax or laugh very much，perhaps because of the effect Lowood school has had on you. But in time you will be more natural with me，and laugh， and speak freely. You're like a bird in a cage. When you get out of the cage, you'll fly very high. Good night.”
56. At the beginning Miss Eyre's impressions of Mr. Rochester were all except_____.
A. busy B. sociable C. dull D. changeable
57. The underlined sentence means_________ .
A. Only by meeting him around the house sometimes did I know a little about him.
B. Only by coming to the house could I know about him.
C. I occasionally met him but my knowledge about him was poor.
D. What I knew about him was limited in the house.
58. From what Mr. Rochester told Miss Eyre, we can conclude that he wanted to _________________. .
A. tell her all his troubles B. tell her his life experience
C. blame her for misunderstanding him D. change his circumstances
59. At the end of the passage，Mr. Rochester sounded ___________ .
A. rude B. cold C. polite D. encouraging
60. According to the passage, which of the following statements is WRONG?
A. Miss Eyre was at Lowood School before she came to Mr. Rochester’s house.
B. Miss Eyre didn’t see Mr. Rochester often.
C. Miss Eyre was honest, brave and confident.
D. Miss Eyre was brave, polite and warm-hearted.
