Eyesight helps us to correct the direction of walking and leads us to the target. Your ears also help you walk. After turning around a lot with your eyes closed, you can hardly stand still, let alone walk straight.
It’s all because your ears help you balance. Inside your inner ear there is a structure which contains liquids. On the sides of the organ are many tiny hair-like structures that move around as the liquid flows. When you spin (旋转) the liquid inside also spins. The difference is that when you stop, the liquid continues to spin for a while. Dizziness is the result of these nerves in your ear. When you open your eyes, although your eyesight tells you to walk in a straight line, your brain will trust your ears more, thus you walk in a curved line.

The research, which followed 200 students for four years, found that women consistently outperformed men in their studies even though they had started their courses with almost identical A-level grades.
An analysis of the results showed that while 65 percent of female graduates were awarded, only 35 percent of male graduates did as well. Girls are known to outperform boys at school, but this research showed that trend continued at university.
Fiona Smith, who led the research, said, “The research shows that the difference has something to do with schools in general.”
“It also shows something about the inequality for working women in terms of pay and promotion. Women work harder at school, harder at university, and do better at both, but they still receive less pay.”
The research found that female students were more faithful, less likely to miss lectures, and more likely to believe that their marks reflected their abilities than male students. Female students were also more likely to ask for and receive support from their professors.
Women were also more likely to choose their universities because they liked the courses offered.
In contrast, men were more likely than women to miss lectures due to “other affairs” and “laziness”, and to believe that playing sports was an important part of university life.
Generally, people think that women’s success comes from more emphasis on coursework, but the research showed that female geographers at Brunel did better in their exams than in their coursework.
Dr Smith said, “Most women feel that getting good grades is the most important part of university life. They believe that they need to work harder in order to compete in the male-dominated (男性主导的) environment they will encounter at work. Good grades are viewed as an ‘insurance policy’ for success. Men, on the other hand, prefer going out and playing sports to academic work.”
“This research shows how important it is to get all young people working hard and teach them the value of higher education,” he said.

Roho Sally has two long arms with human-like hands. She can use her fingers to pick up small objects .examine them in detail and do most things that human hands can do Each finger contains a tiny motor capable of squeezing 20 pounds of pinch foree ,.enough to defuse a bomb under the direction of an operator. She sits on a metal base with wheels that let her move around. turn in tight spaces and climb over small objects, .
Mike McLoughlin is the main investigator for the Applied Physics Laboratory"s Prosthetics Program. "The purpose of that program is to develop prosthetic arms that have all the capability of your natural arms .and you do all the complex motions that we can do with the natural arm- with the robot. "
It was a difficult job. Mr. McLoughlin says the device had to have many small motors to。 have the ability to do what a human hand does; It also needs to have human-like strength. The thumb was especially difficult because it permits the hand .to hold objects. And everything had. to fit into a space about the size of a human hand.
The next problem .he says .was to figure out how to control the artificial hand. " So we had to figure out how to make the connection between the brain and this arm.
For search-and-rescue duties.Roho Sally will be operated by a human being using a wire- less machine that is far from the robot. The operator will also wear special gloves and glasses. The glasses permit the operator to see the robot"s hands .even though they are far away.
Mr. McLoughlin says this kind of robots could be used in what he calls "dull , dirty or dan- gerous" situations where fine human finger movements are required. He says the technology is not ready for everyday application .but he predicts that within five years we will see some won- derful improvements.
小题1:The underlined word " defuse" in Paragraph 2 is closest in meaning to "_________".
| A．remove | B．discover | C．equip | D．produce |
小题3:What can we learn ahout the prosthetic arms according to the passage?
| A．They are expected to function as well as natural ones. |
| B．They have many large motors controlled by robots. |
| C．They have human-like strength to control the robot. |
| D．They are connected with human brains. |
A . Its operator doesn"t need any equipment.
B. It has been Widely used in everyday life in the USA.
C. It can work in situations which are dangerous for humans.
D. It has made much money for the designer.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (顺从) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
小题1:Compared with undirected play, play which is controlled by adults ________.
| A．doesn’t benefit the children at all |
| B．doesn’t help develop leadership and group skills |
| C．makes children become more active |
| D．helps increase physical activity levels |
| A．play offers parents a good chance to establish good relationships with children |
| B．children’s development is greatly influenced by relationships with parents |
| C．play helps children better express their views |
| D．play offers parents a unique opportunity to see the world from a different perspective |
| A．play can’t help children become adapted to the school setting |
| B．play makes social-emotional learning and academic learning separated |
| C．play is beneficial to social-emotional learning as well as academic learning |
| D．it is necessary to strengthen children’s academic development at the expense of others |
| A．Undirected play can help children develop team spirit. |
| B．Play can improve children’s willingness to learn. |
| C．Play helps adults gain a better understanding of the children’s thoughts. |
| D．Adults shouldn’t be involved in children’s play. |
For every course that he follows a student is given a grade, which is recorded. and the record is available for the student to show to potential employers. All this imposes(增加) a constant pressure and stress of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students. the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.
小题1:Normally a student would at least attend __________classes each week.

Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning plant didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature swings—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its fantastically hot summers and fantastically cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned building, where up to 30% of the air is recycled.

| B．A group of buildings together in one place. |
| C．A group of things that are connected. |
| D．A mental state that is not normal. |
| A．By fans. | B．Via ceiling vents. |
| C．Through chimneys. | D．Via ceiling vents and through chimneys. |
| A．Skies without clouds. |
| B．Little dampness. |
| C．Daily rapid temperature changes |
| D．Seasonal rapid temperature changes. |
| A．It changes in a certain range with some exception. |
| B．It changes from one extreme to another. |

| D．It is hard to endure. |
| A．The engineering firm of Ove Arup&Partners. |
| B．How air-conditioning works. |
| C．Fans make Eastgate Building’s temperature comfortable. |
