Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.According to the passage, people are advised to take more Vitamin D, because__.
| A．it is nutritious | B．it can’t harm people’s health |

Who can Garland probably be?
| A．A health researcher | B．A doctor |
| C．A scientist | D．A public health official |
Which of the following food can lower people‘s chance of getting cancer?
| A．Milk | B．Fortified orange juice |
| C．Fortified yogurt | D．All of the above |
People from which area should take more Vitamin D according to the passage?
| A．Asian people | B．African people |
| C．American people | D．European people |
With about 10 million new iPhone 6s ordered in the initial days on the market, a lot of old iPhones are bound to be thrown into the dustbins. Sure, you could sell, donate or recycle your old iPhone, but you probably will not. And there are better things to do with it.
One creative example: At the Missouri University of Science and Technology, a biology class is making old iPhones into microscopes. Using less than $10 worth of supplies, the old phones are mounted onto a lens and can magnify an object to 175 times its size.
Here are 5 smart-and-cheap uses for old iPhones.
Music for your car
Take your music library on the road. Some cars are equipped with docking ports for iPhones and have dashboard screens so you can choose your favourite music hands-free. Or you can just use the cigarette lighter for power.
Remote Control
Televisions, speakers and other devices now have apps that allow users to make their iPhones into fashionable remotes. Carm Lyman, 42, of Napa, California, transformed his iPhone 4 into a remote for his household sound system after his iPhone 5 arrived. Lyman can control the audio levels and activate speakers in various parts of his home as well as access different music services.
Cookbook
No need to go through recipe books or hunt around for other devices when you have a kitchen iPhone. Download a cookbook app, such as My Recipe Book (99 cents) or Big Oven (free), and just leave the device on the kitchen counter. It takes up almost no space and will hold far more recipes than any book.
Baby Monitor
Sure, you can spend $100 or more on a baby monitor, or you can just set your old iPhone up to watch video of your baby in real time as well as hear and even talk to him or her. Cloud Baby Monitor ($3.99) also allows parents to receive the signal on a wireless network or on WiFi so they do not have to be within a certain number of feet of the monitor.
Vehicle Tracker
Whether you need to find your car if it is stolen, record where you have traveled, or spy on your teenage driver, the built-in GPS in your phone can be used as a tracking device. An app like InstaMapper ($2.99) lets you watch the vehicle in real-time and have a record of it. Keep in mind that the phone can still dial 911, even if it does not have cellphone service, Smith said.
You can also use your old phone as a back-up in case your new model suffers irreparable harm. That said, the battery of a phone that sits in a drawer unused could be exhausted to the point where it is no longer workable.We can learn from the passage that an old iphone___________.
| A．can be used as a microscope |
| B．is necessary to be charged regularly |
| C．can light a cigarette in a car |
| D．is able to communicate with a baby |
Who will probably benefit the most from an old iphone?
| A．A housewife | B．A musician |
| C．A traveller | D．A phone user |
If you expect the uses to work properly, ___________.
| A．the wifi is a must |
| B．you are required to download apps |
| C．cellphone service is needed |
| D．some extra work must be done to your phone |
Which of the following statement is true?

| B．The uses can be available in a certain small area. |
| C．An old iphone may give you clues about a stolen car. |
| D．A cookbook app takes up no space of your old iphone. |
Amy Chua may well be very nuts. What kind of a mother will drag her then 7-year-old daughter’s dollhouse out to the car and tell her that it is going to be donated if the poor kid doesn’t master a difficult piano composition by the next day? What kind of a mother will inform her daughter that she is nothing but “garbage”? And what kind of mother will believe, as Chua tells readers, that “an A- is not always a good grade”? The only activities her children should be permitted to do are those in which they can eventually win a medal, which must be gold.
What kind of a mother she is? Why, a mother who is raising her kids in the typical Chinese way, rather than the Western way. In her new book, Battle Hymn of the Tiger Mother, Chua tells her adventures in Chinese parenting, and — so nuts as she may be — she is also mesmerizing (迷惑的). Chua’s voice is that of a happy, knowledgeable serial killer — think Hannibal Lecter — who’s explaining how he’s going to cut his next victim, as though it’s the most self-evidently normal behavior.
There is another attractive aspect of Battle Hymn of the Tiger Mother. There are methods to Chua’s madness, enough method to stir up self-doubt in those readers who support the more educating parenting styles. It is trusted that Battle Hymn of the Tiger Mother is going to be a book club and parenting blog phenomenon; there will be fevered debate over Chua’s tough love strategies, which include unchangeable bans on such Western indulgences (纵容) as sleepovers, play dates, and any after class activities except practicing musical instruments, which must be limited between the violin or the piano.
The back story to Chua’s book is this — she is the daughter of a couple of Chinese immigrants and is now a professor at Yale Law School and the author of two best-selling “big-think” books on “free-market democracy” and “the fall of empires”. When Chua married her husband, her fellow Yale law professor and a novelist Jed Rubenfeld, they agreed that their children would be brought up in “the Chinese way,” in which punishingly hard work, enforced by parents produces excellence; excellence, in turn, produces satisfaction. The success of this strategy is hard to debate. Their older daughter is a piano talent who played at Carnegie Hall when she was 14 or so. The second, a more rebellious (叛逆的) daughter, Lulu, is a gifted violinist. Chua rode the girls hard, making sure they practiced at least three hours a day even on vacations, when she would call ahead to arrange access to practice in hotel lobby bars and basement storage rooms.
Chua also rarely refrained (抑制) from criticizing her daughters. She explains: Chinese parents can do things that would seem unimaginable to Westerners. Chinese mothers can say to their daughters, “Hey so fatty, lose some weight.” By contrast, Western parents have to tiptoe around the issue, talking in terms of "health" and never ever mentioning the f-word, and their kids still end up in treatment for eating disorders and negative self-image. ... Western parents are concerned about their children’s minds. Chinese parents aren’t. They assume strength, not weakness, and as a result they behave very differently.The underlined word “nuts” in the first and second paragraphs most probably means _____.
| A．intelligent | B．crazy |
| C．difficult | D．eager |
Which of the following practices are tough love strategies EXCEPT _______.
| A．Children must get a medal if they attend a competition |
| B．Children should practice piano even on holidays. |
| C．Children are indulged to sleepover, play dates, etc. |
| D．Children are called “garbage” or “fatty” |
What’s the writer’s purpose of using the example of “weight problem”？
| A．To show Chinese parents can do unimaginable things. |
| B．To make a comparison between Western and Chinese mothers. |
| C．To make us believe the western way of parenting is much better. |
| D．To show that Chinese mothers care more about their children. |
From the passage we can learn that Chua’s way of parenting is _______.
| A．widely acceptable | B．very traditional |
| C．quite controversial | D．out of date |
Which is the main idea of the passage?
| A．The Chinese way of parenting has its advantages. |
| B．Battle Hymn of the Tiger Mother is a best seller. |
| C．The westerners are not good at raising children. |
| D．Tiger mothers raise their children in the Chinese way. |
Who cares if money can’t buy you love? But it can still be your best friend forever. That’s one of the surprising findings in a new research paper, “The Power of Money”, published in me journal Psychological Science.
Like any best friend forever, money demonstrated to researchers its ability to soothe us, reduce our sense of social exclusion and even reduce life’s painful moments.
“I was surprised” says Katherine Vohs, one of the researchers and professor at the University of Minnesota’s Carlson School of Management. “The findings were surprising because no one had connected the meaning of money to pain. The money wasn’t buying the subjects more friends; it was only psychologically helpful.”
In the research ,students were told they would be participating in a test of finger dexterity(敏捷度). One group was given some paper money to count, while the other group was given blank pieces of paper. Once the counting was complete, all the test subjects were asked to dip their fingers into bowls of water heated to 122 degrees--roughly the temperature of a very hot bath.
Result? Those who had been counting money reported less pain than those who had not. Subjects also were asked about their feelings. Those who handled actual money reported feeling stronger even 10 minutes after they put down the cash.
Combined with previous experiments, the findings confirmed what researchers have long doubted, that money acts as a general panacea(万能药) in the brain, giving us social self-confidence and reducing physical pain without having to spend a dime on aspirin.
But can we get the same effect by using credit cards? “No, credit cards do not have the same effect, ” Vohs says. “They are scary for most people, and they in fact represent debt m many ways.” The findings could have an interesting effect in the business world, where recent trends have been to issue non-monetary rewards and bonuses instead of what was thought of as “cold, hard cash”.The underlined word “soothe” in Paragraph 2 is the closest in meaning to“_________” .
| A．encourage | B．remind |
| C．calm | D．trust |
What’s Katherine Vohs’s attitude towards the result of the study?
| A．He found it totally unexpected. |
| B．He had no doubt about it. |
| C．He thought it needed further experiments. |
| D．He thought it was not convincing. |
What do we know about the students involved in the study?
| A．They were divided into two groups according to their ages. |
| B．One group was given paper money while the other was given coins. |
| C．They were holding the money while dipping fingers into hot water. |
| D．Both groups were asked to dip fingers into hot water. |
We can 1earn from the passage that_________.
| A．the effect of money can only last until we put it down |
| B．money is both psychologically and socially helpful to us |
| C．the result of the research hasn’t been confirmed（证实）by experts |
| D．credit cards have the same effect on us as money |
The last paragraph suggests that___________.
| A．the recent trend in the business world is to give cash as rewards |
| B．employers should give non-monetary rewards to employees |
| C．cash is a better way to reward employees than credit cards |
| D．more and more employees prefer non-monetary rewards to cash |

Do American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting. But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for 10-15 minutes a day, and then other teachers who basically teach it for 60 to 70 minutes a day --which really for handwriting is pretty much.
Many adults remember learning that way--by copying letters over and over again. Today’s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself. Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.
Handwriting involves two skills. One is legibility, which means forming the letters so they can be read. The other is fluency --writing without having to think about it. Fluency continues to develop up until high school.
But not everyone masters these skills. Teachers commonly report that about one fourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.
But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, which connects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75 percent of students choose to print their essay on the test rather than write in cursive.We can learn ________ from Paragraph 1.
| A．teaching handwriting is a basic requirement in teaching job |
| B．most teachers prefer to teach handwriting |
| C．teachers spend little time in teaching handwriting |
| D．a keyboard has taken the place of the handwriting entirely |
Which of the following is WRONG for traditional handwriting in the USA?
| A．The students are taught by practicing a long period. |
| B．The letters are repeated many times. |
| C．Handwriting includes two skills. |

The underlined word “legibility” in Paragraph 3 means ________.
| A．easy to read | B．complex |
| C．unexpected | D．unreadable |
The best title for the passage is ________.
| A．How to improve handwriting in school |
