Scientists estimate that more than 60 percent of cancer deaths in the United States are preventable through lifestyle changes. Although there is no certain way to avoid all cancers, reducing individual risk factors greatly decreases the likelihood of getting many forms of this dangerous disease.
The American Chemical Society estimates that smoking causes nearly 30 percent of all cancer deaths in the United States — that is, about 166,000 cancer deaths each year. All cancer deaths caused by tobacco smoking could be prevented completely by not smoking and not using smokeless tobacco. For those who already smoke, quitting will reduce the risk of developing cancer. Studies show that after about ten years of not smoking, a past smoker’s risk lowers to about the level of those who have never smoked.
After quitting smoking, eating a healthy diet is the best way to lower the risk of cancer. Certain foods have been found to protect against cancer. Among these foods are cabbages, tomatoes, soy products, and foods high in vitamins A, C, and E. In addition, green and possibly black teas contain compounds that protect the body from cancer-causing substance.
To lower cancer risk, diets should include little or no red meat. Other foods to avoid or consume in moderation (适度地) include sugar, fat from animal products, and salt. Added fats and oils should come from vegetables, such as olives or corn, rather than from animal sources. Carbohydrates (碳水化合物) should come from whole grains, such as brown rice and whole wheat bread, rather than from processed foods, such as white rice and white bread.
The risk of cancer of the esophagus (食道) increases with heavy alcohol consumption, and many studies suggest that consuming alcoholic drinks increases the risk of breast cancer as well. Studies show that limiting intake to two drinks a day for men, and one drink per day for women, reduces cancer risk.
Low levels of physical activity have been implicated (牵连) in some cancer. Moderate activity for 30 minutes a day enhances the immune system, shortens the time food takes to move through the intestines (肠), and changes body composition and hormone levels. Researchers are studying how these effects might lower cancer risk. Which of the following is true according to the author?
| A．A person drinking tea regularly will not be likely to suffer from cancer. |
| B．Once a smoker has stopped smoking, there is almost no chance for cancers. |
| C．A balanced diet is absolutely effective in preventing one from getting cancer. |
| D．Those having quitted smoking for 10 years and non-smokers have less cancer risk. |
What kind of people increase their chances of getting cancers?
| A．Those whose foods contain less sugar, animal fat, and salt. |
| B．Those who are not moderate in drinking, smoking or eating. |
| C．Those who have only one or two drinks regularly per day. |
| D．Those whose diet contains little red meat and a lot of vegetables. |
Which do you think is the best title for this passage?
| A．The relation between food and disease. | B．Causes of different kinds cancers. |

Bob was born in Cambridge. When he was in elementary school, he asked his mother to take him to parks in their community so he could collect empty soda cans to recycle. His mother agreed, as long as he saved part of the money he earned for college.
Bob’s mother remembers Bob as the most determined of her seven kids. Bob’s persistence paid off. On Friday, he will become the first person in his family, originally from El Salvador, to graduate from college. And he’s graduating with university honors.
For his honors thesis（毕业论文）he researched unmanned solar-powered airplanes, which BYU students have been building and testing for about 10 years. Bob’s study helps discover the best way to fly a solar-powered airplane so that it uses the least amount of power. The goal is to design and build an airplane that flies indefinitely. Bob’s thesis helps lay the foundation for this work.
“My parents were always diligent,” Bob said. “They often tell us hard work leads to success. ” Bob’s father taught him to read at the age of 3, and his mother is currently a student at Utah Valley University in a way to becoming a dentist.
Bob acknowledges he overcame some obstacles to get where he is. For starters, English is his second language. He also faced stereotypes（模式化的形象）. Although Bob never doubted that he would be a college graduate, other people assumed he wouldn’t because he didn’t come from a family of high income. There were other obstacles as well, but Bob viewed them all as opportunities.
Bob’s mother says she feels very happy and proud that her son is about to graduate with honors, and remembers the sacrifices he’s made to get there. “He has worked very hard. He started something, and now he has finished it,” Cathy says. “I have always told him, ‘If this is your dream, then you can get it! Keep working hard and you can get it!’”From the passage we can know that Bob’s honors thesis _____ .

Britain's most popular lie has been disclosed, with one in four people admitting using “sorry I had no signal" when returning a missed mobile phone call, a survey found.
Researchers found the average Briton tells on average four lies every day or almost 1500 every year. Almost one in six men admitted they were most likely to lie to their wife or girlfriend, on average at least twice a day. The most popular lie was saying you had no mobile phone signal, with one in four people admitting regularly using the little white lie. It usually came after they hit the “ignore" button when their mobile rang.
Three quarters of people think women are better liars. The research found 46 per cent of girls have been caught lying, compared to 58 of men.
The second most common fib is “I haven't got any cash on me” when asked for money by beggars and Big Issue sellers. “Nothing's wrong – I'm fine” came third followed by “You look lovely” and “Nice to see you”.
Modern technology turned out to have contributed to many lies with “I didn't get your text” in 18th, “Our server was down” in 20th and “My battery died” in 26th place. Other lies to make the top ten included “I'll give you a ring”, “We're just good friends” and “We'll have to meet up soon”. “I'm on my way” and “No, your bum doesn't look big in that” completed the top ten.
In many cases perhaps it is better to delight someone with a fib than destroy someone with the truth, according to a spokesman for OnePoll, which carried out the research of 4,300 adults. He added: ‘As a nation we just like trying to be nice and not upsetting people. Often little white lies can cover what we actually want to say. Most of these were considered completely harmless. ’“You look lovely” and “Sorry, I had no signal” ranked __________ on the popular-lie list.

How many lies does an average Briton tell on average every month?
| A．About 120 | B．About 360 |
| C．About 1,500 | D．About 4 |
Why do British people like telling lies, according to the spokesman for One Poll?
| A．Because truth will destroy others. |
| B．Because British people are very considerate. |
| C．Because it’s easier for others to understand lies. |
| D．Because lies were harmless. |
Learning a second language can improve brain power, scientists believe. US researchers from Northwestern University say bilingualism(双语) is a form of brain training — a mental "work out" that adjusts the mind finely.
Speaking two languages well affects the brain and changes how the nervous system reacts to sound, lab tests showed. Experts say the experiment performed by the National Academy of Sciences provides "biological" evidence of this.
In an attempt to prove the guess that speaking two languages is good for one's mind, the team monitored how the brain of 48 healthy student volunteers reacted to different sounds. Twenty three of these volunteers were bilingual.
The scientists used special equipment to trace the pattern of brainwaves. Under quiet, laboratory conditions, the bilingual students responded in a similar way to the English-only-speaking students, who formed the control group. But the bilingual group were far superior at processing sounds even when there were a lot of people talking in the room. They were better able to focus on to the important information — the speaker's voice — and block out other distracting noises.
Prof Nina Kraus, who led the research, said: "The bilingual's better experience with sound results in a hearing system that is highly efficient, flexible and focused in its automatic sound processing, especially in challenging or novel listening conditions."
Co-author Viorica Marian said: "People do crossword puzzles and other activities to keep their minds sharp. But the advantages we've discovered in double language speakers come automatically simply from knowing and using two languages.''
Musicians appear to gain a similar benefit when rehearsing(彩排), say the researchers. According to some theories, being bilingual might help avoid dementia（痴呆）.What’s the purpose for the lab test led by Prof Nina Kraus?
| A．To find how better the bilingual students can react to sound than other students. |
| B．Just to find scientific proof for a previous guess. |
| C．To show the students how good it is to learn a second language. |
| D．To find a way to prevent dementia. |
What does the underlined word “distracting” mean?
| A．tiring | B．exciting |
| C．interesting | D．disturbing |
What does Viorica Marian seem to believe?
| A．People should do crossword puzzles to keep their minds sharp. |
| B．Bilingual students have more advantages in study than non-bilingual ones. |
| C．Speaking two languages is an easier way for people to increase their brain power. |
| D．Bilingual students are better at solving crossword puzzles. |
What conclusion could be drawn from the passage?
| A．Being bilingual strengthens brain power. |
| B．Speaking a second language can change your nervous system. |
| C．Bilingual musicians perform better on stage. |
| D．The English-only-speaking students can concentrate easily. |

Every year, thousands of young Europeans set off to explore their continent by train in the summertime. It is a necessary part of growing up and often the first time many Europeans travel without their parents. Now you too can share this adventure.
There are so many places you can not afford to miss while travelling in Europe: the Eiffel Tower of France, windmills of the Netherlands and the Colosseum of Rome. How do young people afford to visit everything they want?
The answer lies with the Eurail Pass. This ticket allows a traveller unlimited journeys by rail in European countries which are members of the scheme. Ambitious Chinese travellers can buy the ticket in Beijing, Shanghai and Guangzhou.
The most popular type of Eurail Pass amongst young people, according to Zhao Jiaji, from China Air Service Ltd, is the Eurail Selectpasses. With this you can design your own trip by selecting three, four or five neighbouring countries from a total 18 nations including Liechtenstein, Monaco, Hungary and Romania.
“There is plenty of choice with this pass: in total this range offers over 400 different combinations of countries to choose from!” said Zhao.
The Eurail Selectpass gives 5 to 10 travel days within a 2-month period.
For more flexibility there are the Eurail Passes which allow you to take trains in 17 countries on any day you like. It is valid (有效的)for a period of either 15 or 21 days, one, two or three months.
If you just want to travel in one or two countries to learn more about the local culture, Eurail Pass also offers two-country passes such as Spain-Portugal, France-Switzerland and Belgium-Luxemburg. And countries like Britain, France and Germany offer a kind of Eurail Pass which allows unlimited train travel in their country.
Before buying the Eurail Pass, you should know some tips to save money. The 2nd class train travel ticket is cheaper than 1st class. And youths under 26 years old or groups of 2 or more people traveling together can enjoy discounts.

An Italian couple are becoming the world’s oldest divorcees, after the 99—year—old husband found that his 96—year—old wife had an affair(婚外情) in the 1940s.
The Italian man, called by lawyers in the case as Antonio C，looking through an old drawer when he made the discovery a few days before Christmas.
In spite of the time that had passed since the affair, he was so upset that he immediately asked his wife of 77 years, named as Rosa C, whether it was true, and demanded a divorce.
Stricken by the guilt, she reportedly admitted everything but was unable to persuade her husband to reconsider his decision, though her children also did much more work.
She wrote letters to her lover during a secret affair in the 1940s, according to court papers released in Rome this week , which made people know the truth.
The couple are now preparing to split, though the marriage they built has lasted over nearly eight decades- they have five children, a dozen grandchildren and one great- grand child.
The discovery of the letters was the final problem for their marriage which had already run into difficulty- 10 years ago the husband briefly left their house in Rome and moved in with one of his sons, only to return a few weeks later.
The Italian thought the fierce split resulted from the couple’s southern blood- he is originally from Olbia in Sardinia, while his wife was born in Naples. The couple met during the 1930s when Antonio served as a young officer.
The case appears to set a new record, at least for the age of the oldest figures- the previous oldest couple to divorce were Bertie and Jessie Wood, both aged 98, from the UK.
That pair ended their 36- year marriage in 2009 when they were both two years away from their 100th birthdays. They got married in Elstree, Hertfordshire, in 1972 having both ended previous marriages, before moving to Falmouth, Cornwall four years later.Which is true according to the text?
| A．To find his wife’ affair, Antonio C looked through an old drawer. |
| B．Rosa C’ lover may be Bertie. |
| C．Rosa C admitted what she did because she was sorry for her guilt. |
| D．The Italian thought the fierce split resulted from the discovery of the letters. |
Which word can replace the underlined one in passage5?
| A．advertised | B．announced |
| C．concluded | D．expressed |
Which of the following best describe Antonio C?
| A．a childish man | B．a rude man |
| C．a romantic man | D．a stubborn（固执）man |
The marriage of Antonio C and Rosa C .

| B．appears to set a new record |
| C．may have lasted over 36 years |
| D．began in the 1930s before both ending previous marriages |
