The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world? Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots. 【1】The experiment described in Paragraph 1 is related to the baby's ________. A. sense of hearing B. sense of sight C. sense of touch D. sense of smell 【2】Babies are sensitive to the change in ________. A. the size of cards B. the colour of pictures C. the shape of patterns D. the number of objects 【3】Why did the researchers test the babies with drumbeats? A. To reduce the difficulty of the experiment. B. To see how babies recognize sounds. C. To carry their experiment further. D. To keep the babies' interest. 【4】Where does this text probably come from? A. Science fiction. B. Children’s literature. C. An advertisement. D. A science report. |

Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem. Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass. Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour. However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step. As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice. 【1】Why are race walkers conditioned athletes? A.They must run long distances. B.They are qualified for the marathon. C.They have to follow special rules. D.They are good at swinging their legs. 【2】What advantage does race walking have over running? A.It’s more popular at the Olympics. B.It’s less challenging physically. C.It’s more effective in body building. D.It’s less likely to cause knee injuries. 【3】What is Dr. Norberg’s suggestion for someone trying race walking? A.Getting experts’ opinions. B.Having a medical checkup. C.Hiring an experienced coach. D.Doing regular exercises. 【4】Which word best describes the author’s attitude to race walking? A.Skeptical. B.Objective. C.Tolerant. D.Conservative. |

The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants. The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT. One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps. In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight. Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy. 【1】What is the first paragraph mainly about? A.A new study of different plants. B.A big fall in crime rates. C.Employees from various workplaces. D.Benefits from green plants. 【2】What is the function of the sensors printed on plant leaves by MIT engineer? A.To detect plants’ lack of water B.To change compositions of plants C.To make the life of plants longer. D.To test chemicals in plants. 【3】What can we expect of the glowing plants in the future? A.They will speed up energy production. B.They may transmit electricity to the home. C.They might help reduce energy consumption. D.They could take the place of power plants. 【4】Which of the following can be the best title for the text? A.Can we grow more glowing plants? B.How do we live with glowing plants? C.Could glowing plants replace lamps? D.How are glowing plants made pollution-free? |

The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before. But just as in face - to - face communication, there are some rules of behavior that should be followed when on - line. 【1】 Imagine how you'd feel if you were in the other person's shoes. For anything you re about to send: ask yourself, 'Would I say this to the person's face?' If the answer is no, rewrite and reread.【2】 If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. 【3】 If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room. 【4】 Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it& a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license (特许) to correct everyone else. 【5】 At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended. It is not polite to ask others personal questions such as their age, sex and marital status(婚姻状况). Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions. A.Everyone was new to the network once. B.If you do decide to tell someone about a mistake, point it out politely. C.It's natural that there are some people who speak rudely or make mistakes online. D.The basic rule is simple: treat others in the same way you would want to be treated. E.You should either ignore the person, or use your chat software to block their messages. F.When you send short messages to a person online, you must say something beautiful to Hear. G.Repeat the process till you feel sure that you'd feel comfortable saying the words to the persons face. |
