Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 babies aged 9 months to 36 months. The babies were allowed to choose from seven toys. Some were typically boys’ toys ---- a car, a digger, a ball and a blue teddy. The rest were girls’ toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys；and could pick whichever toy they liked their choice and the amount of time they spent playing with each toy were recorded.
Of the youngest children (9 to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents’ view on which toys were more appropriate for boys or girls, and the children’s choice.
Dr Brenda Todd said, “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer: moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the colour of a newborn baby.”

| A．baby boys are much more active |
| B．baby girls like bright colours more |
| C．their parents treat them differently |
| D．there is a natural difference between them |

| A．Nine-month-old baby boys don’t play with dolls at all. |
| B．Two-year-old baby girls sometimes play with cars and balls. |
| C．The older the babies are, the more obvious their preference is. |
| D．Parents should teach their babies to share each other’s toys. |
| A．Adults purposely influence their babies’ preference. |
| B．Babies’ preference isn’t affected by social surroundings. |
| C．Baby boys preferring to moving toys will be good at hunting. |
| D．Baby girls preferring warmer colors will be warm-hearted. |

Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It"s faster and easier to correct if using a computer. And that"s why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
“When I"m writing with a pen, I find I often can"t remember how to write a character, though I feel I’m familiar with it.”
“I"m not in the mood to write when faced with a pen and paper.”
Many students don"t feel this is something to worry about. Now that it"s more convenient and efficient to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital said, “Chinese characters enjoy both practical and aesthetic (审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer"s emotion. Through one"s handwriting, people can get to know one"s thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory (必修的) and in universities, some professors are asking students to turn in their homework and essays written by hand.
小题1:Which of the following can best serve as the title of the passage?
| A．The Importance of Handwriting and Typing |
| B．To Type or To Hand Write |
| C．Writing By Computer Will Replace Writing By Hand |
| D．Practical and Aesthetic Value of Chinese Characters |
| A．they are usually asked to e-mail their Homework and Essays |
| B．they can correct the mistakes they make quickly and conveniently |
| C．they find it not easy to remember how to write a character |
| D．computers have become a trend and fashion in China |
| A．Handwriting contains the writer"s emotion. |
| B．The writer’s thinking and personality are shown in his or her handwriting. |
| C．Handwriting can impress people well and build one’s self-confidence. |
| D．Chinese characters enjoy both practical and aesthetic value. |
| A．getting bored with | B．getting dependent on |
| C．becoming crazy about | D．getting curious about |
| A．more and more students will give up writing on a computer |
| B．writing by hand will give way to typing by computer one day |
| C．more and more students will pay attention to handwriting |
| D．the typing article better expresses one’s emotion and quality |
Astronomers voted on August 24 to create the first scientific definition of the word planet, and Pluto obviously didn"t make the cut. It turned out to be only a "dwarf planet" (矮行星). After weeks of heated debate, over 2,500 astronomers from 73 countries voted on the definition of a "planet" at a conference of the international Astronomical Union (IAU). According to the definition, a planet must have a clear neighborhood around its orbit. Pluto has widely been considered a planet since its discovery in 1930. Unfortunately, it has a special orbit which overlaps with Neptune"s. It is all because, compared with Neptune, Pluto is very small. It is attracted by Neptune"s gravity when the two planets get closer.
According to IAU, a "dwarf planet" should have an orbit around the Sun. It will not have a clear neighborhood around its orbit, and must not be a satellite. The new classification means that the science textbooks will have to be updated. The solar system is now made up of the eight "classical planets," together with a number of dwarf planets. The classical planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The debate over Pluto"s status started in 1992. After an advanced telescope was sent into space, astronomers started find a belt of objects, which lies beyond Neptune. The belt contains nearly 1,000 objects, including Pluto. As they continued the exploration, scientists recently discovered at least 41 dwarf planets at the edges of the solar system. There are at least two objects of a similar size to Pluto.
It seems that even if the IAU had kept Pluto"s status as a planet, the classical theory of nine planets in the solar system would have had to be changed, but the other way around. More dwarf, planets of a similar size to Pluto would join the family of planets. Scientists will probably find many more dwarf planets.
小题1:According to the passage, Pluto is .
| A．a planet which has a clear neighborhood around its orbit |
| B．a satellite of Neptune which was discovered in 1930 |
| C．the smallest planet in the solar system |
| D．a planet which has an orbit around the sun |
| A．tell us a small fish can hardly survive in the big pond |

| C．mean that a small planet can hardly exist in the solar system |
| D．explain the disappearanee of Pluto in the solar system |
| A．eight | B．nine | C．less than nine | D．more than nine |
| A．According to definition of a "planet", if Pluto were bigger it would not have left the classic planet family. |
| B．It"s quite possible for dwarfs to lose if they compete with big men |
| C．Pluto has a special orbit which overlap with Neptune"s, because it is so small as to be attraeted by Neptune"s gravity when the two planets get closer |
| D．A "dwarf planet", which can not be a satellite without a clear neighborhood around its orbit, should have an orbit around the Sun. |

It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas(热带草原). In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.
小题1:What is the passage mainly about?
| A．Disappearance of African elephants. |
| B．Forests and savannas as habitats for African elephants. |
| C．The effect of African elephants’ search for food. |
| D．The eating habit of African elephants. |
| A．Fixing the time. | B．Worsening the state. |
| C．Improving the quality. | D．Deciding the conditions. |
| A．The African elephant is the largest animal on the earth. |
| B．African elephants have 300 pounds of plants every day, including small trees and underbushes. |
| C．The African elephant is in a way the builder of the environment like other land animals. |
| D．If the African elephant disappears, the whole ecosystem won’t be affected. |
| A．showing the effect and then explaining the causes |
| B．pointing out similarities and differences |
| C．describing the changes in space order |
| D．giving examples |
Memory is said to be stored in the brain as a “memory trace（记忆痕）.” What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means to find out how a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as a measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.
小题1:We can learn from the 2nd paragraph that ___________ .
| A．bad memories may cause rats to fear the dark |
| B．it is hard to tell what a memory trace consists of |
| C．chemical substances carry certain memories |
| D．memory is stored in the brain as a substance |
| A．recognition | B．recall | C．memorization | D．relearning |
| A．The length of the list. |
| B．The type of list items. |
| C．The time difference of relearning. |
| D．The time difference of brain working. |
| A．make the action easy | B．praise it in words |
