单选题According to the passage which of the following is NOT true about tall tales?

单选题It is hard to track the blue whale, the ocean's largest creature which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy's formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies, Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second, slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean especially low-frequency ones can often travel thousands of miles.

单选题The idea of humanoid robots is not new, of course. They have been part of the imaginative landscape ever since Karl Capek, a Czech writer, first dreamed them up for his 1921 play "Rossum's Universal Robots". (The word "robot" comes from the Czech word for drudgery, robota. )Since then, Hollywood has produced countless variations on the theme, from the sultry False Maria in Fritz Lang's silent masterpiece "Metropolis" to the wittering C-3PO in "Star Wars" and the ruthless assassin of "Terminator". Humanoid robots have walked into our collective subconscious, colouring our views of the future. But now Japan's industrial giants are spending billions of yen to make such robots a reality. Their new humanoids represent impressive feats of engineering: when Honda introduced Asimo, a four-foot robot that had been in development for some 15 years, it walked so fluidly that its white, articulated exterior seemed to conceal a human. Honda continues to make the machine faster, friendlier and more agile. Last October, when Asimo was inducted into the Robot Hall of Fame in Pittsburgh, it walked on to the stage and accepted its own plaque. At two and a half feet tall, Sony's QRIO is smaller and more toy-like than Asimo. It walks, understands a small number of voice commands, and can navigate on its own. If it falls over, it gets up and resumes where it left off. It can even connect wirelessly to the internet and broadcast what its camera eyes can see. In 2003, Sony demonstrated an upgraded QRIO that could run. Honda responded last December with a version of Asimo that runs at twice the speed. In 2004, Toyota joined the fray with its own family of robots, called Partner, one of which is a four-foot humanoid that plays the trumpet. Its fingers work the instrument's valves, and it has mechanical lungs and artificial lips. Toyota hopes to offer a commercial version of the robot by 2010. This month, 50 Partner robots will act as guides at Expo 2005 in Aichi, Japan. Despite their sudden proliferation, however, humanoids are still a mechanical minority. Most of the world's robots are faceless, footless and mute. They are bolted to the floors of factories, stamping out car parts or welding pieces of metal, machines making more machines. According to the United Nations, business orders for industrial robots jumped 18% in the first half of 2004. They may soon be outnumbered by domestic robots, such as self-navigating vacuum cleaners, lawn mowers and window washers, which are selling fast. But neither industrial nor domestic robots are humanoid.

单选题To be successful in a job interview, you should take care to appear modestly dressed, avoiding the extremes of too elaborate or too casual attire. On the positive side, clothes may be a good leveller, putting you on a bar with other applicants. On the other hand, clothes which are too informal may convey the impression that you are not serious about the job or that you may be casual about your work as well as your dress. Clothes which are too elaborate, too colorful, or too expensive suggest that you don't understand what behaviour is appropriate for the job. The right clothes at the fight time, however, gain the respect of the interviewer and his confidence in your judgement. It may be not true that "clothes make the than", but the first and often lasting impression of you is determined by the clothes you wear. Besides care for personal appearance, you should pay close attention to the manner of speaking. You should speak in a clear voice, loud enough to be heard without being aggressive or overpowering. Your speech should not can attention to itself, but it should reveal your individuality and ability. Obviously you must speak without grammatical mistakes or dialect differences. You should be prepared to talk knowledgeably about the requirements of the position you are applying for in relation to your own experiences and interests. Knowing something about the position enables you to ask intelligent questions about the work and the requirements for the job. The interviewer can decide from the questions asked whether you are interested or knowledgeable. You can comment on your own training, experience, and other qualifications. The interviewer can determine whether your background and potential seem to fit the position. The position for which you are applying is not only the safest: topic for discussion; it is essential that you demonstrate your understanding of the requirements and your abilities in meeting these requirements. Finally, you must convey a sense of self-confidence and enthusiasm for work. You can demonstrate self- confidence by your manner of speech and dress. You further show it by being prepared for the interview. In addition, the way you enter the room, sit, look at the interviewer, and fill out application forms and other papers may express self-confidence The eagerness with which you discuss the job rather than the salary may re- veal your enthusiasm for work You may express it through your questions and comments about working conditions and facilities. And your previous experience and success will tell the interviewer about your enthusiasm for work. Self-confidence and enthusiasm for work are valued highly by all interviewers.

单选题In many U.S. cities thousands of young people are developing their minds as well as their bodies by learning karate. In the United States, karate is currently taught in more than fifty special schools, and in an increasing number of high schools and colleges. Karate is a science of unarmed self-defense and counterattack. It is a sort of "weapon in an empty hand". In fact, karate means "empty hands" in Japanese. A highly skilled practitioner of karate, called a "karateka", uses his hands, fists, fingers, elbows, feet, and shrill yells as a weapon to ward off his assailant's attack. Karate requires a great deal of coordination and long practice to perfect the blocks, strikes, and light taps that are used for self- defense. Beginners learn to squat, sit up, pivot and stretch, jump and kick waist- high. Karate blows are so dangerous that trainees practice them without bodily contact with an opponent. They are able to smash boards and bricks with a clenched fist or the edge of their hands. Not all karate training is physical. Karatekas spend a great deal of time in meditation in order to train their minds to know exactly where their opponents' weak and strong points are, so that they can cope with them. This mental training also helps increase the karatekas' self-confidence to defeat their assailant successfully or to avoid violence completely, in fact, master karate practitioners have disciplined their bodies and minds so well that they rarely need to fight. It is believed that a Buddhist monk in India invented karate in the sixth century A.D. and taught it to Chinese monks who brought it to the island of Okinawa and called it "kungfu". In the early seventeenth century, when the Japanese invaded Okinawa, they took every weapon from the people. Over the years, the Okinawans secretly developed karate to a high degree to repel their enemies. Since the 1960s karate has been a popular sport in many countries, and may even be a part of the official Olympic competitions in 2000. The color of a karateka's belt indicates his level of karate expertise. Beginning students wear white belts, and can advance to the level of the black belt — a very high honor that few people attain. Although most students of karate never earn a black belt, of which there are ten levels, they do become more self- disciplined individuals who can defend themselves when necessary. For Bobby Hamilton and Paula Jones, karate not only is a means of self-defense, but also it gives them new knowledge and spiritual balance to cope with our increasingly complex world.
