As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents.The power of the school has been replaced by the home.To begin with, all the factors which are part of intelligence—the child's understanding of language，learning patterns, curiosity—are established well before the child enters school at the age of six.Study after study has shown that even after school begins, children's achievements have been far more influenced by parents than by teachers.This is particularly true about learning that is languagerelated.The school rather than the home is given credit for variations in achievement in subjects such as science.
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.

When several different people look at the same person，it's not unusual for each of them to see different things；when you alone observe one behavior or one person at two different times，you may see different things.The following are but some of the factors that lead to these changing perceptions(感知认可)．
(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.
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
2.While observing a particular person，________.
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
3.Observation of the same person by two people at the same time may differ because
________.
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
NEW YORK (Reuters Health)—Kids who eat better perform better in school, a new study of Nova Scotia fifthgraders confirms.
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.
1.．According to Dr.Paul J．Veugelers, students who have a healthy diet________.
A．are more likely to fail in their school performance
B．definitely can perform better in their school work
C．usually have more of fat and less of fruit and vegetables
D．tend to perform better in their school work
2.．It can be implied from the passage that________.
A．little research has been done on the importance of breakfast
B．most students participating in the research failed the test
C．the adequacy and variety of foods can mean better school performance
D．eating more chicken nuggets leads to good school performance

A．the ability to read and write
B．a guessing game
C．the art of painting
D．the ability to handle practical task
4.．Which of the following statements is TRUE?
A．Children should have more“junk food”at lunch time.
B．Preschool diets can have more impact on children's school work.
C．A child who often has“junk food”at 3 is bound to fail in school work.
D．The older a child is，the more impact of what he eats has on school work.
Some people can stay up all night and still get work done the next day.I'm not one of them.After a night without enough sleep, I feel badtempered.I have trouble remembering things.And all I want to do is to crawl into bed and sleep.
How do you feel after you've stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” affects how well you function without sleep.The “period 3” gene comes in two forms：short and long.Everyone has two copies of the gene.So, you may have two longs, two shorts, or one of each.Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”．Study participants had to stay awake 40 hours straight.Then，they took tests that measured how quickly they pushed a button when numbers flashed on screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did.In both groups，people performed worst in the early morning.
After the first round of experiments，participants were finally allowed to sleep.People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
People with the long “period 3” gene, by contrast, fell asleep in just 8 minutes.They also spent more time on deep sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of“period 3”．What about you?
