If your preschoolers turn up their noses at carrots or celery, a small reward like a sticker(貼畫(huà)) for taking even a taste may help get them to eat previously disliked foods, a UK study said.
Though it might seem obvious that a reward could encourage young children to eat their vegetables, the idea is actually controversial, researchers wrote in the American Journal of Clinical Nutrition. That’s because some studies have shown that rewards can backfire and cause children to lose interest in foods they already liked, said Jane Wardle, a researcher at University College London who worked on the study. Verbal praise, such as “Brilliant! You’re a great vegetable taster”, did not work as well.
The study found that when parents gave their small children a sticker each time they took a “tiny taste” of a disliked vegetable, it gradually changed their attitudes. The children were also willing to eat more of the vegetables—either carrots, celery, cucumber, red pepper, cabbage or sugar snap peas—in laboratory taste tests, the study said.
Researchers randomly assigned (分派) 173 families to one of these groups. In one, parents used stickers to reward their children each time they took a tiny sample of a disliked vegetable. A second group of parents used verbal praise. The third group, where Parents used no special vegetable-promoting methods, served as a “control”.
Parents in the reward groups offered their children a taste of the “target” vegetable every day for 12 days. Soon after, children in the sticker group were giving higher ratings to the vegetables—and were willing to eat more in the research lab, going from an average of 5 grams at the start to about 10 grams after the 12-day experience. The turnaround(轉(zhuǎn)機(jī)) also seemed to last, with preschoolers in the sticker group still willing to eat more of the once-disliked vegetable three months later.
Why didn’t the verbal praise work? Wardle said the parents’ words may have seemed “insincere” to their children.
小題1:The purpose of writing the passage is      .
A．to show the procedure of an experiment on children’s diet
B．to introduce a practical method of making children eat vegetables
C．to explain why children hate to eat vegetables
D．to present a proper way of verbal praise to parents
小題2:The underlined word “backfire” in Paragraph 2 probably means “_______”.
A．shoot from behind the back

B．Children in the sticker group will never lose interest in eating vegetables.
C．Oral praise works quite well in encouraging children to eat vegetables.

When author Nicholas Carr began researching his book on whether the Internet is ruining our minds，he restricted his online access and e­mail.His new book argues the latest technology renders us less capable of deep thinking.Carr found himself so distracted(分心的) that he couldn’t work on the book while staying as connected.After first feeling confused by his sudden lack of online connection，he was able to stay focused on one task for a long period within several weeks.
Reading on the Internet has changed how we use our brains.Facing a lot of texts，video，music and links to other web pages and blogs，our minds have become used to skimming and scanning information.As a result，we have developed sharper skills at making fast decisions，particularly visual ones，Carr wrote.
But now most of us seldom read books or long articles that would help us focus.We are becoming more like librarians—able to find information quickly and see clearly the best nuggets(有價(jià)值的資料)．That lack of focus hinders(阻礙) our long­term memory，leading many of us to feel distracted，he wrote.
“What we are losing is a whole other set of mental skills，which require not the shifting of our focus but the maintaining of our focus，” Carr said，adding that for centuries books protected our brains from distraction and focused our minds on one topic at a time.
But with devices such as Apple’s iPad becoming common，Carr predicts books also will change.“New forms of reading always require new forms of writing，” he said.Carr has a suggestion for those who feel web surfing has left them incapable of concentration—slow down，turn off the Internet and practice the skills of contemplation(沉思) and reflection.“It is pretty clear from the brain science that if you don’t exercise particular cognitive skills，you are going to lose them，” he said.“If you are constantly distracted，you are not going to think in the same way that you would think if you paid attention.”
小題1:What topic is Nicholas Carr’s new book mainly concentrating on?
A．Whether there is any need for us to surf the Internet.
B．How the Internet changes our way of thinking.
C．What we should do when we are surfing the Internet.
D．Whether our minds are being influenced by the Internet.
小題2:How did Nicholas Carr feel after he limited his time online several weeks later?
A．Anxious.B．Relaxed.
C．Concentrated.D．Puzzled.
小題3:The underlined word renders in Paragraph 1 probably means ________.
A．preventsB．causes
C．protectsD．sharpens
小題4:What’s Nicholas Carr’s suggestion for people who are often distracted by the Internet?
A．They should read more books besides surfing the Internet.
B．They should often slow down their pace of modern living.
C．They should often get away from the disturbing of the Internet.
D．They should spend more time thinking while surfing the Internet.

I am a psychologist. I first met Timothy, a quiet, overweight eleven­year­old boy, when his mother brought him to me to discuss his declining grades. A few minutes with Timothy were enough to confirm that his self-esteem (自尊) and general happiness were falling right along with them.
I asked about Timothy’s typical day. He awoke every morning at six thirty so he could reach his school by eight and arrived home around four thirty each afternoon. He then had a quick snack, followed by either a piano lesson or a lesson with his math tutor. He finished dinner at 7 pm, and then he sat down to do homework for two to three hours. Quickly doing the math in my head, I found that Timothy spent an average of thirteen hours a day at a writing desk.
What if Timothy spent thirteen hours a day at a sewing machine instead of a desk? We would immediately be shocked, because that would be called children being horribly mistreated. Timothy was far from being mistreated, but the mountain of homework he faced daily resulted in a similar consequence — he was being robbed of his childhood. In fact, Timothy had no time to do anything he truly enjoyed, such as playing video games, watching movies, or playing board games with his friends.
Play, however, is a crucial part of healthy child development. It affects children’s creativity, their social skills, and even their brain development. The absence of play, physical exercise, and free­from social interaction takes a serious toll on many children. It can also cause significant health problems like childhood obesity, sleep problems and depression.
Experts in the field recommend the minutes children spend on their homework should be no more than ten times the number of their grade level. As a fifth­grader, Timothy should have no more than fifty minutes a day of homework (instead of three times that amount). Having an extra two hours an evening to play, relax, or see a friend would soundly benefit any child’s life quality.
小題1:What did the writer think of Timothy after learning about his typical day__________?
A．Timothy was very hard­working.
B．Timothy was being mistreated.
C．Timothy had a heavy burden.
D．Timothy was enjoying his childhood.
小題2:Which of the following statements best describes the writer’s opinion________?
A．Children should be allowed enough time to play.
B．Playing board games works better than playing video games.
C．The more they play, the more creative children will become.
D．The depression caused by homework makes children unwilling to play.
小題3:According to the passage, how long should a third­grader spend a day doing homework________?
A．About ten minutes.B．No more than twenty minutes.
C．No more than thirty minutes.D．About fifty minutes.

Across the United States, universities and colleges have been looking to become more sustainable (可持續(xù)發(fā)展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.
At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.
All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building would. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”
小題1:We can learn from the text that the EcoDorm in the US     .
A．offers students the chances to have a natural living at college
B．was firstly built by two college students
C．was designed for saving building materials
D．is only applicable in few schools
小題2:The second paragraph is mainly about     .
A．where the EcoDorm was built
B．when the EcoDorm got its name
C．what the EcoDorm is made of
D．how the concept of EcoDorm started
小題3:What is the advantage of the EcoDorm?
A．It helps students to enjoy life at college.
B．It saves a lot of money and energy for the college.
C．It makes students study harder.
D．It brings new energy to the college.
小題4:What can be inferred from the text?
A．A long-term development calls for students’ efforts.
B．Students’ ideas should be encouraged at college.
C．Green living is a new trend at American colleges.
D．Students can learn to protect the environment through practice.

Researchers conducting a study of hospital stays for over two hundred and eighty six thousand older folks found something interesting in their data.
The number of hospitalizations for heart disease and stroke went down significantly among a certain group of people at a certain time of year. What folks, and what time of year, you ask? Flu season and the lucky people were the ones who got flu shots(流感疫苗).
It’s generally recommended that people over fifty get their flu shots every year. Influenza(流行性感冒) is no small thing. it’s responsible for around thirty six thousand deaths a year in the U. S. alone. Getting the shots also cuts down on the chances of get­ting pneumonia(肺炎), which is especially dangerous in seniors.
But what wasn’t known was that there seems to be an added benefit to getting a flu shots in terms of warding off heart problems. The data,in fact, are quite strong in suggesting this is the case.
In this study, flu shots cut clown the number of hospitalizations for heart disease by nineteen percent. Stroke went down sixteen percent one season and a whopping twenty-three percent a second season.These are big results.
So what's the connection between getting a flu shot and having a stronger heart? It isn’t yet known.
Researchers speculate that the flu virus itself may do damage to blood vessels(血管), possibly making clots(血塊)more likely. Blood clots in the heart can cause heart attacks, and blood clots in the brain can cause strokes.
Whatever the specific details are, there's one more good reason to follow your doctor’ s advice and get that annual flu shot.
小題1:According to the study, the number of hospitalizations for heart disease and stroke went down significanntly among the ones who _____.
A．got flu shots after they were ill

C．it can kill the flu virus
D．if can make blood clots
小題3:The underlined phrase "warding off" probably means_______.
A．keeping awayB．dealing withC．setting offD． picking up

Way back in 1662，John Evelyn，a brilliant Englishman known for his detailed diaries，wrote about disastrous effects of coal-burning on the city of London .In it,he described an infernal scene of smog．a(chǎn)ir filled with “Columns and Clouds of Smoke’’given out by small industries and residences that burned coal for fuel．
I found the description in the 2003 book When Smoke Ran like Water，by epidemiologist(流行病學(xué)家)and environmental advocator(倡導(dǎo)者)Devra Davis．In it,Davis looks back at several historic pollution events and their disastrous effect on human human health-and at how these phenomena were often Ignored or even actively covered up by then people in charge at that time.
As Davis points out，John Evelyn was ahead of his time when writing about how London’s polluted air affected  the well-being of its residents．It wasn’t  until nearly 300 years later,after what became well-known as the Great Smog of 1952，that the government began to address the problem in a systematic way．
For four days．Between December 5th“and 9th“，due to all accident of the weather pattern，the city was buried in a heavy fog .People were still burning coal for fuel，and low-grade coal at that time， because 0f wartime condition．A temperature inversion(轉(zhuǎn)向)trapped the smoke from the city’s fires， creating a black cloud in which people could barely find their way down the most familiar streets

not pan out．
Davis writes that even today in this country ,we still have not completely absorbed the lessons of similar events．Sixty years the killer fog lifted in London，people are dying preventable deaths and suffering life．changing illnesses，simply because they must breathe the air of the cities where they live

Although websites such as Facebook and MySpace experienced rapid growth during the middle of the first decade of the 21st century, some users remain unaware of the fact that the information they post online can come back to haunt them. First, employers can monitor employees who maintain a blog, photo diary, or website. Employers can look for controversial(引起爭(zhēng)議的) employee opinions, sensitive information disclosures, or wildly inappropriate conduct. For example, a North Carolina newspaper fired one of its features writers after she created a blog on which she wrote about the strange things of her job and coworkers without signing her real name.
The second unintended use of information from social networking websites is employers who check on prospective employees. A June 11, 2006 New York Times article reported that many companies use search engines and social networking websites such as MySpace, Xanga, and Facebook to conduct background checks on college campuses. Although the use of MySpace or Google to check a student’s background is somewhat unsettling to many undergraduates, the Times noted that the use of Facebook is especially shocking to students who believe that Facebook is limited to current students and recent alum(校友).
Corporate employers are not the only people interested in college students’ lives. The third unintended use of social networking websites is college administrators who monitor the Internet — especially Facebook — for student bad behavior. For example, a college in Boston’s Back Bay expelled (除名) its student Government Association President for joining a Facebook group highly critical of a campus police sergeant. In addition, fifteen students at a state university in North Carolina faced charges in court for underage drinking because of photos that appeared on Facebook.
Although more users of websites such as Facebook are becoming aware of the potential dangers of online identities, many regular users still fail to take there basic security precautions(警惕). First, only make your information available to a specific list of individuals whom you approve. Second , regularly search for potentially harmful information about yourself that may have been posted by mistake or by a disgruntled
(不滿的)former associate. Thrid, never post obviously offensive material will likely make its way to the wider world. By taking these simple steps, members of the digital world can realize the many benefits of e-community without experiencing some of the damaging unintended consequences.
小題1:The main purpose of the passage is to _____.
A．explain the growth of the digital world from the view of privacy
B．discuss the risks of the digital world and suggest ways to protect yourself
C．propose steps Facebook, MySpace and Google can take to protect user privacy
D．illustrate(說(shuō)明) potential unintended uses of private information
小題2:The writer implies that users should take all of the following actions to protect their online privacy EXCEPT _____.
A．know to whom you make your online information available
B．a(chǎn)ctively hunt for damaging information posted about you or under your name
C．speak with employers to inform them of any misinformation published about you
D．a(chǎn)void uploading information that would be extremely damaging if it were discovered
小題3:According to the passage, which of the following does the author imply?
A．Information obtained unwillingly from the Internet is permitted in court.
B．It is impossible to protect yourself from unintended uses of information online.
C．Even if you restrict who can view your data, the government may still access it.
D．Done properly, posting offensive information about oneself brings no risk.
小題4:In the last paragraph the author mainly _____.
A．offers detailed examples to support previous viewpoints
B．further explores the ill-effects of the Internet on the protection of privacy
C．summarizes the points of the above paragraphs
D．provides suggestions to overcome the previously mentioned problems

Do you like seahorses? What do you know about them?
The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎動(dòng)物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?  
小題1:We can learn from the passage that seahorses _______.
A．a(chǎn)re beautiful, and live on seaweed
B．a(chǎn)re as big as regular horses
C．live near deep channels
D．like to be alone
小題2:The third paragraph tells us that _______.
A．male seahorses lay eggs
B．seahorses mate in spring or autumn
C．male seahorses give birth to babies
D．seahorses mate in warmer waters at night
小題3:Which of the following protects seahorses from being eaten by their enemies?
A．Their fast speed of swimming.
B．Their ability to change colours.
C．Their unique eyes.
D．Their strong tails.
小題4:Which of the following can replace the underlined word "grasp"?
A．Eat.B．Hold.C．Make.D．Handle.
