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 member of a team at San Diego Moores
Cancer Hospital 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 units 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 color, could also
benefit significantly from a higher intake," the authors said.
B. it can"t harm people"s health
C. it can lower cancer risk
D. it is not taken enough every day
B. a doctor
C. a medicine scientist
D. a public health official

C. Fortified yogurt.
D. All of the above.
B. African people
C. American people
D. Oceanian people

students found another use-capturing tests as a way to cheat.
The Magnolia Independent School District in Montgomery County has added camera phones to a
list of electronic devices (器具) students are banned from having at school.
School officials said the move was made as a preventative measure to stop potential (潜在的) test
cheaters, since students could use the phones to snap pictures of test questions. Another concern was
that students might take inappropriate (不合适的) pictures of classmates to later share or post on a
website. Cell phones without cameras are allowed on campus, but must be turned off. Camera cell
phones will be taken away from students if found on campus, and disciplinary action will be taken,
officials said.
Some students were unhappy to hear about the ban. "I"d be lost without my phone," said Kendall
Paul, a Magnolia High School student. "All my numbers are in it. I"ve never used it to cheat and I don"t
know anyone who has at our school, so I think it"s kind of stupid. " But other students said they saw it
all the time at their school.
"You would take a picture of the test and then send it to the next person taking the test," said Melissa
Sparks, a student.
"They would send the question and the answer, or just the number of the question and the answer. It"s
quicker that way," another student said.
Parents often provide their children with cell phones for use in emergencies(紧急情况)and to keep in
better touch with them. "My Mom wants me to have my phone with me all the time for emergency purpose. So, it goes with me wherever I go," Paul said.
B. Allowed to have.
C. Ordered to have.
D. Kept having.
B. Students" parents are in favor of the ban.
C. Students have different opinions about the ban.
D. Students can use cell phones without camera freely at school.
B. The writer thinks that the ban is right.
C. The writer thinks schools shouldn"t invade (侵犯) students" rights.
D. The writer"s opinion is not mentioned in the passage.
B. some students get lost without their camera cell phones
C. the School District"s ban is stupid
D. some students cheat in exams with camera cell phones
where barely literate (受过教育的) high school athletes get their transcripts (成绩单) by
taking courses occasionally and sometimes by taking no courses at all. The athletes then go
on to famous sports universities, where they exhaust their playing years before landing back
on the streets without job opportunity or college degrees.
The prep school scheme was meant to avoid academic qualification rules for college athletes
made years ago by the National Collegiate Athletic Association. The N.C.A.A., which was
slow to recognize the seriousness of the problem, has finally adopted policies to root it out. But
those policies will not do the job unless everyone is involved, including prep schools and college
athletics departments that still recruit (招收) students who do not meet academic standard.
The prep school scheme sends a dangerous message to poor neighborhoods, where young
people too often ignore their studies, believing that they will magically become millionaires once
the world sees their athletic talents. Even worse, it encourages students to drop out of traditional
schools before graduation-at which point their grade-point averages would be written in stone-to
sign up with fake schools that can help them rewrite their academic records.
The N.C.A.A. has begun to check nontraditional schools for their academic programs and has
actually closed some. The organization has also stepped up to look into athletes" transcripts and
will pay special attention to athletes who attended several schools, showed sudden jumps in
grade-point average, transferred to another school late in the senior year or took an unbelievable
number of courses in one term.
These measures are encouraging as far as they go. But the N.C.A.A. will need to go much
deeper into the problem if it hopes to break this scheme. For starters, it needs to make clear
not just what courses high school athletes need to take to become qualified for college sports,
but when they should take them. Until that happens, those who recruit young athletes will always
be tempted(受诱惑的)to make fake academic record at the last possible moment for them.
B. They can easily be admitted to a university by cheating.
C. After they graduate from university, they will usually find promising jobs.
D. They seldom have good academic performance at high school.
a lot of courses in one term.
B. Transcripts of high school students can be very important reference for students to go to college.
C. Most High school athletes can probably be awarded a bachelor"s (学士) or master"s degree
after they graduate from universities.
D. Transcripts of high school students are so important that they are recorded on metal
from__________________.
B. many prep schools that carry out poor academic programs for high school athletes
C. many college athletics departments that still recruit academically unqualified students
D. school athletes, poor management of prep schools and irresponsibility of related college
departments
the measures EXCEPT____________________.
B. shutting down some unqualified prep school
C. listing compulsory courses and the number of course needed to be taken in high school
D. checking some problematic transcripts
B. The writer thinks more practical measures are needed to break it.
C. The writer remains neutral (中立的) on this issue.
D. The writer believes poor children will have little chance to go to college if prep school
scheme is broken.
to use hydrogen to drive the engine, in much the same way as many cars use gas. The second
method is to use the reaction of hydrogen with oxygen in a battery, making the car a kind of
electric one.
The dream of producing hydrogen in the car while driving along by electrolyzing (电解)water
is a long way off, so we are still at the period of batteries and filling the tank with hydrogen gas.
This is the difficulty for potential car users and producers. There are only sixteen hydrogen filling
stations in Los Angeles and none in 99% of other cities worldwide.
Indeed, some of the big name automobile producers have pulled out of the race to put the first
practical hydrogen car on the streets. Ford and GM have announced that they are pulling out in
America and so has Renault in France.
However, the Japanese companies are pressing on. In fact, Honda introduced its first hydrogen
fuel cell car in 1999. They are now producing second generation hydrogen car known as the
FCX Clarity. Guess where they are available for sale? In only one city because of its filling stations.
Honda thinks that they could go into full-scale production of the FCX Clarity by 2020 if the
world is prepared for them by then.
Then there are hydrogen-powered buses in several European cities including Amsterdam,
Barcelona, Hamburg, London, Luxembourg and Madrid. Lotus, the makers of London taxis,
have announced that they propose to manufacture hydrogen-powered taxis in time for the London
Olympics.
So, the hydrogen vehicle is out there and the numbers will be growing fairly soon. The buses
go back to their bus station, where an electrolyzing machine changes water into fuel for them to
fill up on and the same will be the case for many of London"s taxis.
Unfortunately, getting fuel is not the only difficulty for the average motorist, a number of these
vehicles cost about $300,000 each.
B. are likely to sell well in the future.
C. are mainly used in the United States
D. won"t be used in the London Olympics
B. Hydrogen buses
C. The FCX Clarity
D. Filling stations
B. In Hamburg
C. In London
D. In Los Angeles
B. hydrogen vehicles fueled by water will be very expensive
C. Honda will mass-produce the FCX Clarity by 2012
D. Honda produced its first hydrogen car in 1989
children were given regular carrots and, on other lunch days, they were given the same vegetables which
were renamed X-ray Vision Carrots.
The study suggests kids like vegetables with cool names better and the influence of these names might
continue to exist. Children continued to eat about 50 percent more carrots even on the days when they
were no longer called cool names.
The research, which was funded (资助) by the Robert Wood Johnson Foundation, was put up at the
yearly meeting of the School Nutrition Association in Washington DC.
"Cool names can make for cool foods," says Brian Wansink of Cornell University. "Whether it is "
power peas" or "dinosaur broccoli trees," giving the food a fun name gets kids to think that it will be more
fun to eat. And it seems to keep working-even on the next day," Wansink said.
Similar results have been found with adults. A restaurant study showed that when the Seafood Filet was changed to Succulent Italian Seafood Filet, sales increased by 28 percent and the taste rating (评级)
increased by 12 percent. "The same food, but different expectations, and different experience," said
Wansink, the author of Mindless Eating: Why We Eat More Than We Think.
The study was done in pre-schools (幼儿园), but the researchers believe the same tricks can work
with children .
"I"ve been using this with my kids at home," said a researcher Collin Payne. "Whatever inspires their
imagination seems to inspire their appetite (胃口)."

people feeling unhappier. So, putting a brave face on your sadness could be harmful. The research also
found that women suffered more than men when pretending to be happy.
Dr. Brent Scott, who led the study, said employers should take note because forcing workers to smile when dealing with the public can result in bad outcomes. He said, "Smiling for the sake of smiling can lead
to emotional tiredness, and that"s bad for the organization." He also said the research showed
customer-service workers who had "fake smiles" throughout the day fell into a bad mood and didn"t want
to work, so their productivity dropped.
The study is one of the first of its kind to examine emotional expressions over a period of time and
compare the different effects on men and women.
Dr. Scott"s team examined the effects of "surface acting", or fake smiling, compared to "deep acting",
or making people smile by thinking of pleasant memories. Dr. Scott said, "Women were harmed more
by surface acting, meaning their moods worsened even more than men"s. However, they were helped
more by deep acting, which means their moods improved more by thinking of pleasant memories. "
According to Dr. Scott, women tend to suffer more when pretending to be happy because they are
expected to be more emotionally expressive than men. Therefore, forcing a smile while feeling down is
more likely to go against their normal behavior and cause more harmful feelings.
Although deep acting can improve moods a little in the short term, Dr. Scott says, it"s not a long-term
solution to feeling unhappy. "There have been some suggestions that if you do this over a long period you
start to feel unreal. You"re trying to develop positive emotions, but at the end of the day you may not feel
like yourself any more."
B. is meaningful as there haven"t been many similar ones
C. examined more women than men for a long time
D. aimed to make the employees more productive
B. they should be more emotionally expressive
C. they are often treated in a terrible way
D. they like thinking of pleasant memories
B. cannot improve our moods in any case
C. harms our feelings in the long run
D. pleases people by feeling like another person
B. Women shouldn"t be forced to smile.
C. An important suggestion for workers.
D. Why people don"t want to work
