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.

Recently,university students around the world were asked to volunteer in a global experiment called Unplugged.It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours.
Unplugged is being run by Dr Roman Gerodimos，a lecturer in Communication and Journalism at Bournemouth University.During the experiment，Dr Gerodimos said there were already signs of how much the exercise affected volunteers.He said：“They’re reporting withdrawal symptoms，overeating，feeling nervous，isolated and disconnected.”
During their 24-hour test，three of the experiment’s participants were followed around by a BBC reporter plus cameraman.They were asked to write down 100 lines about their day offline，but of course，they all waited until the next day when they had access to their laptops.
Elliot Day wrote：“Today,my whole morning routine was thrown up into the air.Despite being aware of the social importance of the media,I was surprised by how empty my life felt without the radio or newspapers.”
From Caroline Scott，we read：“I didn’t expect it，but being deprived of the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual…I didn’t break out in a cold sweat like our lecturer expected us all to，but It’s not something l would like to do again！”
And Charlotte Gay wrote：“I have to say the most difficult item for me to be without has been my mobile；not only is it a social device，it’s my main access point of communication.”
Earlier in the year,a UK government study found that in the UK we spend about half our waking hours using the media,often plugged into several things at once.So,with technology continuing to develop at an alarming rate,how much time will you set aside for sleep in the future?What can we learn about the volunteers?
| A．Volunteers didn’t write down about their day offline. |
| B．Volunteers weren’t allowed to use any media for 24 hours. |
| C．Volunteers were followed around by Dr Roman Gerodimos. |
| D．Only volunteers in the UK took part in Unplugged experiment. |
Which of the following is NOT mentioned about the participants’feelings？
| A．Anxious. | B．Lonely | C．Bored. | D．Despaired. |
Which of the following is true of Caroline Scott？
| A．The media ban affected his temperature. |
| B．His work went on smoothly without the media. |
| C．His work was carried on hard without the media. |
| D．His life was empty without the radio or newspapers. |
What can be inferred from the last paragraph?
| A．People should use the media devices reasonably. |
| B．People can easily survive the media devices addict. |
| C．People can spend more time sleeping in the future. |
| D．People spend about half the time using the media devices. |

London has become a cycle friendly zone after the launch of a new bike hire 
scheme.It has been designed to encourage more people to cycle in and around central London.
So how does it work？First you have to sign up to the scheme to be sent a key.The key will unlock one of the bikes，which are kept at docking stations in and around central London.You have to pay an access fee for the key and then you pay as you go，for he length of time you use the bike.
Transport for London， which runs the scheme，are hoping to have 6，000 bikes and 400 docking stations in place by the end of the year.The new hire system is hoping to ease congestion in London and is expected to generate up to 40，000 extra cycle trips a day into the city centre.London Mayor Boris Johnston launched the scheme and said London had been “filled with thousands of gleaming machines that will transform the look and feel of our streets and become as commonplace on our roads as black cabs and red buses”.
However，there have been a few problems since the scheme was launched last Friday.On the first day some people found they couldn’t dock their bike properly and their usage of the bike had not registered.Transport for London did admit they had been expecting a few “teething problems”and have said they wouldn’t charge for the first day as a“gesture of goodwill”.Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles.
Despite the comments，the green-thinking London Mayor still seems very positive about things，saying，“My campaign for the capital to become the greatest big cycling city in the world has taken a gigantic pedal-powered push forwards.”A new bike scheme has started in London to.

From a very early age，some children exhibit better 
self-control than others.Now，a new study that began with about 1，000 children in New Zealand has tracked how a child’s low self-control can predict poor health，money troubles and even a criminal record in their adult years.
Researchers have been studying this group of children for decades now.They observed the level of self-control the youngsters displayed.Parents，teachers，even the kids themselves，scored the youngsters on measures like“acting before thinking”and “Persistence in reaching goals.”
The study led by Moffitt of Duke University and colleagues followed 1，000 children from birth to age 32 in Dunedin,New Zealand.
“The children who had the lowest self-control when they were age three to ten，later on had the most health problems in their 30s，” Moffitt said， “and they had the worst financial situation.They were more likely to have a criminal record and to be raising a child as a single parent on a very low income.”Moffitt explained that self-control problems were widely observed，and weren’t just a feature of a small group of misbehaving kids.
Moffitt said it’s still unclear 
why some children have better self-control than others，though she said other researchers have found that it’s mostly a learned behavior,with relatively little genetic influence.But good self-control can be set to run in familles because children with good self-control are more likely to grow up to be healthy and prosperous parents.But the good news，Moffitt said，is that self-control can be taught by parents，and through school curricula that have been shown to be effective.From the first two paragraphs we learn that .
| A．the research has been carried out for five years |
| B．self-control in kids tends to determine their future |
| C．self-control was assessed by children’s intelligence |
| D．children’s self-control is almost the same at early age |
Children with low self-control are more likely to .
| A．become wealthy in later life | B．get good school performance |
| C．have better financial planning | D．adopt negative behaviors |
According to Moffitt，.
| A．only good genetic factors can shape their lives in the future |
| B．scientists know well why some children have better self-control |
| C．self-control in childhood has nothing to do with criminal activity |
| D．willpower as a child really influences people’s chances of adulthood |
What can be inferred from the passage?
| A．Self-control cannot be taught in schools. |
| B．The study is restricted within few participants. |
| C．It’s never too late to deal with self-control problems. |
| D．Good parenting can improve self-control and life success. |
.Which of the following might be the best title of the passage？
| A．Child’s self control predicts future health，success |
| B．Kids are encouraged to take risks at an early age |
| C．Children’s development cannot be changed by teachers |
| D．How to teach the kids a bit of self-control in schools |
This is a story that happened 15 years ago but it has always stayed with me since then.On the way back from work every evening,more often than not there would be a homeless man standing at the exit of the freeway.He always waved at every car,he was always happy and smiling and sometimes almost dancing.Every day after work when I got there，I would quickly roll down my window and give him the coins.Occasionally the red light would be on for a minute and we would ask each other about our day.His answer would always be the same，“I’m blessed！”.
It amazed me that even in his situation of being homeless he was so positive，and his answer would remind me of how blessed I was.A single mother of four amazing kids,with a place to call home and with a job to provide for my kids.Then one day I was called into my boss’s office and was told that I was being laid off due to the economy.Needless to say that on my was home that day I was very sad and upset.I didn’t remember to look for my spare change and keep it ready like I usually did.I wasn’t feeling the joy as I got off the ramp where the homeless man would be.Yet there he was as alway，as l turned the ramp.He set his eyes on me，while still smiling and waving at others.
While I was waiting for the red light to turn，he strolled over to my car.He had a big smile he looked me straight in the eyes and said “today I will give you a dollar”.He then reached into his pocket and pulled out a dollar bill.I was blown away.I burst into tears.I wanted to jump out of my car and hug him！

Tokyo - Drivers in China are no longer in a hurry to own Toyota Motor Corp's cars.
Neil Hu, a sales manager at a Toyota dealership in Beijing, said he has stopped charging a 5,000 yuan ($732) premium to customers who want to skip the waiting list for RAV4 sport- utility vehicles. He took the initiative after the Japanese carmaker recalled 75,552 of the SUVs in China last month to fix gas pedals that may stick.
"I heard the situation in the US is pretty bad for Toyota," Hu said. "The recall has impacted us as well."
Toyota, which grew more slowly than competitors in China in 2009, will likely lose more market share and see a decline in local profit margin this year, analysts say. The carmaker has relied on a reputation for quality and safety to sell high margin, mid- to large-size models even as the world's biggest auto market shifts to cheaper, smaller cars, encouraged by government incentives.
With Toyota's brand damaged by global recalls of millions of vehicles, profit margins for its SUVs and Camry and Crown sedans may shrink, said Ashvin Chotai, London-based managing director of Intelligence Automotive Asia Ltd, an industry consultant.
"With this recall saga, Toyota's premium pricing power in China is gone," Chotai said. "Toyota's cars don't have enough good value for money."
Toyota has lost $24.5 billion in market capitalization this year as it recalled over 8 million cars globally to fix defects linked to unintended acceleration. The company faces at least 118 class actions in the US and at least 36 individual lawsuits claiming deaths and injuries caused by sudden acceleration of Toyota or Lexus vehicles.
Toyota President Akio Toyoda flew directly to Beijing on March 2 to apologize for the vehicle defects, after attending US Congressional hearings about the recalls in Washington. He skipped Europe's Geneva auto show, underscoring the growing importance of the Chinese market.
Toyota rose for a fifth straight day in Tokyo, advancing 0.9 percent to 3,580 yen as of 9:44 am local time. The carmaker's shares have fallen 7.7 percent this year.
The company's February China sales rose 30 percent to 45,400 vehicles, underperforming the overall passenger-car. According to the passage, why did Toyota carmaker recall their cars in China last month? _____________
| A．Because it faced law suits in the US |
| B．Because there were problems with the cars. |
| C．Because of the importance of the Chinese market |
| D．Because the customers are not satisfied with the charging of a 5,000 Yuan premium. |
What does the underlined phrase“take the initiative” mean?
| A．took the advice | B．changed his mind | C．took the action | D．made the decision |
Why did Toyota president Akio Toyota skip Europe’s Geneva auto show?
| A．Because he did not think it important |
| B．Because he was not satisfied with the hearing in the US |
| C．Because he attached importance to the Chinese Market |
| D．Because he needed to make an apology to Chinese |
After the global recalls of millions vehicles, Toyota will be impacted in the following aspects, EXCEPT_________.
| A．Its brand will be damaged |
| B．Its profit margins will shrink |
| C．It will have to face law suits |
| D．The president will be fired |
