Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a literacy test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found.
While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifthgraders participating in the Children"s Lifestyle and Schoolperformance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment.
The better a student"s eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test.
To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition(营养不良).
“This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children"s nutrition at breakfast but also that throughout the day,” the researchers conclude.
Another research from the UK is suggesting that children"s diets in the preschool years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets(块) they ate at lunchtime.The researchers say they have found that children who ate a diet of “junk food” at the age of three, made less progress in school between the ages of six and ten.They say children"s diet at later ages appears to have less impact on their school attainment.

试题【NEW YORK (Reuters Health)—Kids who eat better perform better in school, a new st】;主要考察你对题材分类等知识点的理解。[详细]
举一反三
(1)Each person"s perceptions of others are formed by his or her own cultural conditioning education,and personal experiences.
(2)Sometimes perceptions differ because of what we choose to observe and how we deal with what we"ve observed.It is not necessarily true that person"s perception is based on observations of a particular person.Your observations may be totally controlled by what others have told you about this person;or you may focus (聚集)primarily on the situation or role relationship.Most people do not use the same yardstick(标准)to measure their parents,their friends and strangers.
(3)Sometimes we see only what we want to see or don"t see what may be obvious to others because of our own needs,desires,or temporary emotional states.This is a process known as selective perception.Selective perception is obviously more difficult when contradictory (矛盾的)information is particularly obvious,but it can be done.We can ignore(忽视)the “stimulus”.He"s basically a good boy so what I saw was not shoplifting.
We can reduce the importance of the contradictory information—All kids(孩子)get into mischief(顽皮).Taking a book from the bookstore isn"t such a big deal.“We can change the meaning of the contradictory information.” It wasn"t shoplifting because he was going to pay for it later.
小题1:The first factor given by the author that affects our perception is ________.
A.the abilities of one"s auditory (听觉的)and visual (视觉的)sensors |
B.cultural background and personal experiences |
C.experiences one learns from others |
D.critical measures taken by other people |
A.one is likely to take all aspects(方面)to consideration |
B.one pays more attention to his/her advantages |
C.children often differ from grownups in perception |
D.one tends to choose certain cues(提示)to look for |
A.their measuring yardsticks are not the same |
B.either of them may be slow to catch information |
C.the time for observation is not long enough |
D.each of them uses different language to express his/her impressions |
In view of their power, it"s sad to see so many parents not making the most of their child"s intelligence.Until recently parents had been warned by educators who asked them not to educate their children.Many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.
Parents have been particularly afraid to teach reading at home.Of course,children shouldn"t be pushed to read by their parents, but educators have discovered that reading is best taught individually—and the easiest place to do this is at home.Many fourand fiveyearolds who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.
小题1:What have researchers found out about the influence of parents and the school on children"s intelligence?
A.Parents have greater influence than the school. |
B.The school plays a greater role than parents. |
C.Parents and the school have the equal power. |
D.Neither parents nor the school has any influence. |
A.it is with the help of the teachers that children have an understanding of language |
B.curiosity is formed after the children enter school |
C.children"s learning patterns are developed at the early age |
D.only the school can give children the opportunity to make achievements |
A.Moral education. | B.Language education. |
C.Physical education. | D.Science education. |
________.
A.they usually push the children to read at home |
B.they only teach them after they enter school |
C.they teach them in a wrong way at home |
D.they were told by educators not to teach their children |
Algae,like corn,soybeans,and other crops,grow via photosynthesis (光合作用) and can be processed into fuel oil.However,they yield 30 times more energy than land crops such as soybeans,according to the U.S.Department of Energy.Many algae species also can grow in saltwater and polluted water-while corn and soy require arable land and fresh water that will be in short supply as the world"s population balloons.
“If you replaced all the diesel (柴油) in the U.S.with soy biodiesel,it would take half the land mass of the U.S.to grow those soybeans,”says Matt Caspari,chief executive of Aurora Biofuels,a Berkeley,Calif.-based private firm that specializes in algae oil technology.On the other hand,the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States,it would require 15,000 square miles,which is a few thousand miles larger that Maryland (12,407 square miles),the 42nd state in land area.
Another bonus:Because algae can be grown just about anywhere in a closed space,they "re being tested at several power plants across the nation as a carbon absorber.Smokestack emissions (烟囱排放物) can be pumped directly into the ponds,feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles—is improving,it"s still years away from reaching your local gas pump.“It"s just a question of cost,because no large-scale facilities have been built yet,” Caspari says.
小题1:The underlined word “yield” in Paragraph 2 can be replaced by “________”.
A.control | B.require |
C.produce | D.grow |
A.may pollute water and soil |
B.can grow in poor conditions |
C.provide much less energy |
D.need more special care |
A.it can be used more widely |
B.it is more easy to produce |
C.it needs much less land |
D.it costs much less money |
A.Algae help protect the environment. |
B.People can grow algae anywhere. |
C.Fish can get more oxygen from algae. |
D.Algae produce less waste. |
It"s a message that many a mom and dad has tried to impress upon many a youngster(and some notsoyoungsters)who spends perhaps a bit too much time with game controllers in hand.
But the 40yearold Langteau isn"t a parent.He"s experienced at video games-one who played producer on three “Medal of Honor” games and cofounded his own game development company.
Langteau has just published a children"s book called“Sofa Boy”,which tells the story of a kid who spends too much time sitting on the couch with controllers held in hand and the rather dire consequences that follow.
It"s a fairy tale picked straight from Langteau"s own experiences as a lad with a fondness for video games and his painful struggle against game addiction.But first,Langteau would like make one thing clear:I"m not saying that you shouldn"t play video games.I think video games are great.I think they do great things for kids.Instead,Langteau says his book is all about a little something called“moderation(克制)”.
“It"s about being well rounded,”he says.“Just like with anything else,we all need to make sure that there"s a variety in what we do.”
Video gamers can be rather badtempered when it comes to accepting criticism about their favorite entertainment.And understandably so.After all,most people who go around talking about the dangers of playing video games tend to be outsiders-people who don"t play video games and certainly don"t understand that they can be a valuable and healthy form of entertainment.
But Langteau and“Sofa Boy”seem to be in a unique position to deliver a message of gaming moderation that the young game masses might actually listen to.After all,this is a man who understands what it means to be a kid with a passion for games.His early experience has taught him a lesson.
小题1:Scott Langteau published “Sofa Boy” to ________.
A.share his great skills on games |
B.warn kids against game addiction |
C.tell about his fairy tale as a kid |
D.deliver a message for games |
A.The book tells of the writer"s own story. |
B.The book describes an experienced gamer. |
C.The boy in the book wins a medal for games. |
D.The boy in the book is not an addict on games. |
A.Langteau advises the young to play games within limits |
B.Langteau advises the young not to play games |
C.playing video games ruins the future of kids |
D.playing video games is of no benefit to kids |
A.games do great things for kids |
B.gamers are usually fat and round |
C.games should be viewed from all sides |
D.gamers are to blame for their behaviors |
It was Thursday, September 12,1940.Four French teens were out exploring in the woods off the northern slopes of the Pyrenees.Many years before, an old pine tree fell and left a large hole in the ground.The teenagers were curious and they started to explore the area and fell into one of the most important archeological(考古的) finds of the twentieth century!
There are over a hundred limestone(灰岩) caves in this region of France.Some were inhabited by humans thousands and thousands of years ago.Between 15,000 and 17,000 years ago, humans painted lively creatures such as cows, bulls, horses, and even cats on the walls of the caves.
Why did they mark these walls? Was it to tell a story? Was it to record a famous battle? There are many mysteries and ancient secrets still waiting to be discovered in the cave of Lascaux.There were dots in many of the paintings.What do these dots mean? Were they meant to record time, a calendar? Deep in the cave, there is a drawing of a “birdman”.What does this mean? Was it a place for sacred ceremonies? No one knows for sure.
The actual cave of Lascaux was closed in 1963 due to the overabundance of tourists visiting the site.The carbon dioxide that people were breathing out was causing damage to the fragile(易损的) cave paintings.Up till now the Lascaux cave is still closed for tourists.Only a specialist can visit the cave by a special order that must be made out almost a year in advance.Not more than six persons can enter the cave per day.Two days a week, the cave is completely closed.Due to the great interest of numerous tourists, in 1983 Lascaux Ⅱwas opened for tourism.It is an exact replica of the cave of Lascaux.
小题1:The Pyrenees are the __________ in France.
A.mountains | B.forests |
C.rivers | D.caves |
A.built | B.explored | C.lived in | D.destroyed |
A.old | B.beautiful |
C.easily damaged | D.interesting |
