studied works of art made at different times from 1500 B.C. to the 1950s. Most of the people shown in these
works are right-handed so the scientists guessed that right-handedness has always been common through
history. Today, only about 10% to 15% of the world"s population is left-handed.
Why are there more right-handed people than left-handed ones? Scientists now know that a person"s two
hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right
hand is u8ed to work with things. This is because of the different work of the two sides of the brain. The right
side of the brain, which makes a person"s hands and eyes work together, controls the left hand. The left side
of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show
that more artists should be left-handed, and studies have found that left-handedness is twice as common among
artists as among people in other jobs. No one really knows what makes a person become right-handed instead
of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain
is damaged when they are bom. However, this doesn"t happen to everyone, so scientists guess there must be
another reason why people become left-handed.
One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基
因) for right-handedness, he/she may become either right-handed or left-handed according to the chance and
the people they work or live with. Though right-handedness is more common than left-handedness, people no
longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use
their right hands like other children, but today they don"t have to.
B. the works of art ended in the 1950s
C. most people shown in the works of art are right-handed
D. most people shown in the works of art are left-handed
B. It"s used to work with things.
C. It"s used to make a person"s eyes and hands work together.
D. It"s the centre for thinking and doing problems.
B. Left-handedness is cleverer than right-handedness.
C. Today children are made to use their right hands only.
D. Scientists think there is no reason why people become left-handed.
B. Left-handed People

| Zipped into a bag, it looks like a large umbrella. Unfolded, it goes along the street like any other bicycle. It"s the "A-bike", the brainchild (脑力劳动的产物) of British inventor Sir Cive Sinclair, who made history in the 1970s hy devel oping the world"s first pocket calculator. He described his new invention as "the world"s smallest, lightest foldable bicycle". "My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used," said Sinclair. The mini-bike showed in Singapore last week and set to go on sale worldwide in 2005 at a price of nearly US $300, is built for riders as heavy as 112 kilograms and is height-adjustable (可调整高度的). It takes about 20 seconds to fold or unfold. Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists. "You require no extra energy to ride the A-bike and it can go up to 15 miles per hour (24 kilometers per hour)," he said. Constructed mainly of plastic, the 5.5-kilogram bicycle folds into a package of less than 0.03 cubic meters (立方米). Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the A-bike was to add an electric motor in a few years. |

| The girls in this sixth grade class in East Palo Alto, California, all have the same chance to use computers as boys, but researchers say, by the time girls get to high school, they may be victims (牺牲品) of what researchers call "a major new gap in technology". "Girls are likely to be less comfortable than boys with the computers. They use it more for word processing rather than for problem solving rather than discover new ways in which to understand information." After reexamining a thousand studies, the American Association of University Women Researchers found that girls make up only a small percentage of students in computer science classes. Girls usually consider themselves significantly lower than boys in their ability and confidence in using computers. And they use computers less often than boys outside the classroom. Six years ago, the software company Purple Moon noticed girl"s computer usage was falling behind boys. The number one reason girls told us they don"t like traditional computer games is not because they"re too violent or much too competitive. Girls would say they"re boring. Purple Moon says it found what girls want: characters they can relate to and story lines relative to what"s going on in their own lives. "But we found from girls that there"s no intrinsic (内在的) reason why they wouldn"t want to play on the computer. It was a just a content thing." The sponsor (发起人) of the study says: The technology gap that separates girls from boys must be closed if women are to compete effectively with men in the Twenty First Century. |
| 1. The American Association of University Women Researchers found _____. |
| A. girls prefer to solve problems rather than use word processing with the computer B. girls are lack of ability and confidence in using computers C. only a small number of girls attend the computer science classes in high school D. the girls don"t like computer games because they are too violent or competitive |
| 2. According to the study of Purple Moon, computer games aren"t considered _____ by the girls. |
| A. interesting B. violent C. competitive D. boring |
| 3. If the content of traditional computer games changed, most girls would probably _____. |
| A. be against them B. be in favor of them C. give up using word processing D. learn computers quickly |
| 4. In the sponsor"s opinion, why must the technology gap be got rid of in the 21st century? |
| A. Because women can have an effective competition. B. To improve women"s social position. C. For an unknown reason. D. Because bosses won"t look down upon women. |

| Working at home is increasing in popularity as a means of escaping from nine-to-five office life. Why work under the constant watch of your boss when you can work in front of the TV in your carpet slippers? Armed with all the office essentials-telephone, computer, e-mail and fax, many workers believe they can work as effectively as their colleagues in the office. Being able to work wherever you like: from a busy city to a beautiful village, and make working from home an attractive choice, you can even work on a canal boat, like one Internet firm in the Midlands, US. So what will become of the office of tomorrow? I believe it is likely that many could disappear into cyberspace. To minimize office overheads in inner-city areas, companies will apply a workforce made up of a network of home workers linked by an advanced communication and information system. A central processing computer would be controlled by the manager who sends"out work schedules and oversees the activity of each employee. As a successor to the Web Cam, a video screen would be created, as the need for more natural form of interaction than e-mail or telephone becomes greater. Capturing the mood and expressions of work colleagues, managers would have the ability to view several employees at once on their screen. Employees would be encouraged to feed any information that may be useful to fellow workers into the computer to make the company work more effectively. As the company"s life blood, the computer would contain a record of all conversations and correspondence for future reference, and hold confidential information such as accounts in password protected areas. In the office of tomorrow, with daily life captured in detail, the case for firing employees could be more cleat cut. |

| A. in space B. a network C. in inner-city areas D. a central processing computer |
| 3. In Paragraph 2, the underlined word "oversees" probably means _____. |
| A. overlook B. organize C. make out D. watch over |
| 4. A video screen would be built because _____. |
