At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage buildings or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice．
Here is a way to kill mice without spending a lot of money. It is a simple but effective kind of mouse trap. The method is first used by some farmers in the west African country of Mali. An agricultural expert in Mali reported about the Mali mouse trap in a magazine. The expert reported that his gardener caught 150 mice in just one night. The gardener used four traps. The trap is easy to make. First, remove the top from a 20 liter metal or plastic container(容器). Put it in a hole in the ground. The top edge of the container should be the level with the surface of the ground. Fill the container with water to within eight centimeters of the top. Add tiny pieces of grain wastes. They should float on the water. Also put some wastes on the ground near the trap. During the night, mice will come out to eat the grain wastes. They will fall into the container and drown. Replace the food in the trap every night．

When people think of the unique characteristics of Beijing the hutong style always comes to mind.It is no exaggeration(夸张) to say within hutong lives the city's history.
The word hutong was borrowed from the Mongolian word to mean “water well” about 700 years ago.Later it referred to a place where people live.Hutong we see today are made up of small lanes formed by walls of siheyuan.They were built during the Yuan, Ming and Qing dynasties.
When the People's Republic of China was founded in 1949, there were more than 3,000 hutong.Most of the city's population lived in this traditional housing.But with the modernization of the city in the 1980s and early 1990s, many hutong were pulled down to build roads, skyscrapers and modern houses.
The government has recognized the importance of hutong to Chinese cultural heritage(文化遗产)．In 2002, Beijing listed 40 protected historical zones and increased its efforts to restore some key relics and older streets in the city.Nearly 500 hutong have survived.
Hutong that still exist are like oases(绿洲) of calm surrounded by the noisy city.Walking through them, it's common to see groups of elderly citizens sitting together playing cards, mahjong or Chinese chess.In the early mornings and evenings, they gather to practice traditional forms of exercise such as taijiquan as well as dancing and singing folk songs or Peking Opera.Hutong have become a museum of Beijing's folk customs and history.What is the original meaning of the word hutong?
| A．Small lanes. | B．Water well. |

What does the phrase “pull down” mean in Paragraph 3?
| A．Replace. | B．Destroy. |
| C．Restore. | D．Establish. |

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.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. |
Researchers conclude that________.
| 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 |
According to the text, in which area may school play a more important role?
| A．Moral education. | B．Language education. |
| C．Physical education. | D．Science education. |
Many parents fail to make the most of their children's intelligence because
________.
| 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 |
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.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 |
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 |
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.．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 |
．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 |
．The underlined word “literacy” (in Para.2) probably refers to ________.
| A．the ability to read and write |
| B．a guessing game |
| C．the art of painting |
| D．the ability to handle practical task |
．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?The purpose of this passage might be________.
| A．to tell us the importance of plenty of sleep |
| B．to tell the result of a research on sleepy gene |
| C．to inform the harm of lacking sleep |
| D．to announce the sleeping rules of humans |
Which of the following decides how well you perform without sleep?
| A．One short form. |
| B．One long copy. |
| C．One short and two long copies. |
| D．Period 3. |
What kind of people need less sleep according to the research?
| A．Those with two long copies of the gene. |
| B．Those with two short copies of the gene. |
| C．Those with one short and one long copy of the gene. |
| D．Those with three short copies of the gene. |
If one lacks enough sleep，one should avoid doing important or dangerous things ________.
| A．at dawn | B．at night |
| C．in the afternoon | D．at noon |
