A robot is machine designed to work like a living person. The word robot was actually invented in 1920 by Karel Capek, a Czechoslovakian writer. But although the word is quite new, the idea of machines acting like people is very old. In the second century BC, Philon of Byzantium designed statues that performed clever tricks. Today throughout the world thousands of real robots do many important tasks that help people. Robots can do many of the things that people do, as well as some things people can't do. Many of the tasks that robots perform are boring or actually unhealthy for people. Some robots are built to explore places too dangerous for people to visit. They can take pictures and send back useful information without putting people at risk. One of the areas where robots explorers are used extensively is in space. Astronauts need special equipment to survive in space. Robots do not need air, water or food. They can work on distant planets keeping in touch with Earth by radio signals. NASA's Sojourner Rover was the very first robot to travel across part of another planet. In 1997, the six-wheeled rover explored part of the surface of Mars. The test robot Afghan Explorer may one day visit war zones. Working as a war reporter, it could send pictures and interviews back to a TV station in a safer place. The Dante 2 is similar to the Afghan Explorer. This eight-legged robot can climb into the crater of a red-hot volcano to collect gas samples(样本) and take photos with its eight cameras. Nomad Rover, another robot explorer, is the size of a small car. It has trekked through hot deserts and icy lands on it own, collecting information for scientists at home. Many robots work underwater. They map the ocean floor, monitor sea life or find sunken wrecks(残骸). These robots can travel deep underwater far more easily than people. Robots can stay underwater for many days at a time and travel hundreds of kilometres exploring the oceans. Underwater robots, such as Deep Drone, can travel to the ocean floor and help recover crashed aircraft or sunken ships. Deep Drone can travel around 40 times deeper than unprotected human divers. Some robots are rescue robots: they can save lives. They do this by fighting fires, searching for survivors after disaster, or handling dangerous objects such as unexploded bombs. Bomb disposal robots can look at suspect packages with their cameras. They relay the information to someone at a safe distance. As robot technology advances, our robots are becoming smarter and are able to help us with more and more aspects of our lives. Robots have enhanced our work efficiency greatly. Robots won't always be machines hidden away in dangerous factories. Work is already being done to develop robots which will help us in our kitchens or on our farms. What do you think robots might be doing to help us in the future? 1. Which of the following aspects is Not mentioned in the passage? A. Military. B. Astronomy. C. Education. D. Rescue. 2. What is the best title of the passage? A. Robots: A Valuable Resource B. Robots: Future Applications C. Living in the Robot Age D. Leading a Robot-Style Life 3. Which of the following is Not true according to the passage? A. The Afghan Explorer has not been put in use yet. B. The Dante 2 is used to collect information about volcanoes. C. Nomad Rover can endure miserable weather conditions. D. Deep Drone is designed to protect human divers.

阅读理解(共两节，满分40分)第一节(共15小题；每小题2分，满分30分)阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。AA new generation addiction is quickly spreading all over the world.Weboholism，a twentieth century disease，affects people from different ages.They surf the net，use email and speak in chat rooms.They spend many hours on the computer，and it becomes a compulsive habit.They cannot stop，and it affects their life.Ten years ago，no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users.This obsessional behavior has affected teenagers and college students.They are likely to log on computers and spend long hours at different websites.They become hooked on computers and gradually their social and school life is affected by this situation.They spend all free time surfing and don’t concentrate on homework，so this addiction influences their grades and success at school.Because they can find everything on the websites，they hang out there.Moreover，this addiction to websites influences their social life.They spend more time in front of computers than with their friends.The relation with their friends changes.The virtual life becomes more important than their real life.They have a new language that they speak in the chat rooms and it causes cultural changes in society.Because of the change in their behavior，they begin to isolate themselves from the society and live with their virtual friends.They share their emotions and feelings with friends who they have never met in their life.Although they feel confident on the computer，they are not confident with real live friends they have known all their life.It is a problem for the future.This addictive behavior is beginning to affect all the world.56．What is the main idea of the passage?A．The cause of weboholism.B．The advantage of weboholism.C．The popularity of weboholism.D．The influence of weboholism.57．The underlined word “obsessional” in the second paragraph most probably means “________”．A．attractive B．addictiveC．professional D．potential58．We can infer from the passage that________.A．weboholism has the greatest effect on teenagersB．students can hardly balance real and virtual lifeC．people are addicted to games on the InternetD．virtual life is more vivid and attractive anyway59．Which of the following is NOT true of weboholism?A．It contributes to the development of the web.B．The chat room language may change social culture.C．The problem will be getting more and more serious later.D．People addicted to the web often become inactive in real life.BWhat is your favorite color？Do you like yellow，orange or red？If you do，you must be an optimist (乐观主义者)，a leader，or an active person who enjoys life，people and excitement.Do you prefer gray or blue？If you do，then you are probably quiet，shy and you would rather follow than lead.If you love green，you are strongminded and determined.You wish to succeed and want other people to see you are successful.At least this is what psychologists tell us，and they should know，because they have been seriously studying the meaning of color preference，and the effect that colors have on human beings.They tell us that we don’t choose our favorite color as we grow up.If you happen to love brown，you did so as soon as you opened your eyes，or at least as soon as you could see clearly.A yellow room makes us feel more cheerful and more comfortable than a dark green one，and a red dress brings warmth and cheer to the saddest winter day.On the other hand，black is depressing.Light and bright colors make people not only happier but also more active.It is a fact that factory workers work better，harder，and have fewer accidents when their machines are painted orange rather than black or dark gray.Remember，then，that if you feel low，you can always brighten your day or your life with a new shirt or a few colorful things.Remember that you will know your friends and your enemies better when you find out what colors they like and dislike as well.And don’t forget that anyone can guess about your character when you choose a piece of handkerchief or a lampshade.60．The author believes in the passage that________.A．anyone can choose his color preference in his lifeB．no one can choose his color preference in his lifeC．anyone is born with his color preferenceD．no one is born with his color preference61．According to the passage，________.A．if you enjoy life，you must like yellow，orange and redB．if you are quiet，you must prefer gray or blueC．if you love green，you usually do what you have decidedD．if you love pink，you often go to flower shops62．Psychologists study the meaning of color preference because________.A．colors may affect the emotional states of the peopleB．colors may decide the results of our work and studyC．color preference can tell you who your friends areD．color preference can help you to see through your enemies63．The main idea of this passage is that________.A．color preference has something to do with one’s characterB．colors have effects on human psychological statesC．you will know your friends or your enemies by knowing the colors they likeD．all of the aboveCThe Poetry Foundation，recently named American poet Jack Prelutsky as the nation’s first children’s poet laureate (桂冠诗人)．The group created the award as a way to increase children’s love of poetry.As children’s poet laureate，Jack Prelutsky will give two public readings in the next two years.He will also advise the Poetry Foundation about children’s literature and take part in projects concerning children and poetry.Jack Prelutsky has been writing poetry for children for almost forty years.He has written more than thirtyfive books of poems.His first book was called A Gopher in the Garden.It was published in 1967.His latest is called Behold the Bold Umbrellaphant and Other Poems.Jack Prelutsky is well known for creating new words by combining two words to create a new kind of creature.For example，he combined “radish” with “shark” to get “radishark”．“Lion” and “broccoli” became “broccolion”．He also created “umbrellaphant”，a mixture of the words “umbrella” and “elephant”．Jack Prelutsky says that children like his poems because he writes about things they care about.Poetry researchers say that Jack Prelutsky’s poems recognize children’s feelings.An example of this is the poem My Sister Is a Werewolf which is about how it feels to be different.Jack Prelutsky also writes poems about American holidays.His poem It’s Halloween is a very famous one about the holiday celebrated at the end of October.64．Which of the following can be the best title of the passage?A．Poems with New Words Grow PopularB．First Children’s Poet Laureate NamedC．Children’s Love for Poetry IncreasedD．Jack Prelutsky Awarded Nationwide65．What is Jack Prelutsky famous for?A．Creating new words in his poems.B．His productivity.C．His long time of writing.D．His poems about American holidays.66．Children are in favour of his poems because________.A．they are easy to understandB．the poet is famousC．children like reading new wordsD．the poet understands their feelings67．What can we infer from the passage?A．It was A Gopher in the Garden that brought him fame.B．The poet will be kept busy over a lot of activities.C．Jack Prelutsky will no longer write about American holidays.D．The poem It’s Halloween must have been written for adults.DFor a 400yearold art form，opera had a bad fame：overweight actresses singing the words which were hard to understand in one of those romantic languages you were supposed to learn in high school.And with tickets costing as much as 145 a performance，operagoers also had a certain appearance in people’s mind：rich，welldressed and old.But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to keep opera alive and take it to a younger and not so wealthy audience.Opera producers have found that to attract this crowd，they need to associate opera with the common people.That means no formal suits，oldstyled theatre or bankbreaking ticket prices.And because young people don’t or won’t come to the opera，companies are bringing the opera to them，giving performances in such usual places as parks，libraries and public schools.The Houston Grand Opera’s choice is the public library，where it performs “mobile operas”，shortened versions of childfriendly operas.This summer’s production is Hansel & Gretel.By performing smaller versions of large productions，producers are able to make people interested while keeping costs at a reasonable level.The San Francisco Opera，which will be celebrating its 75th anniversary this year，is staging Cinderella free of charge，keeping costs down by employing students from its Young Artists’ Training Program.68．Which is the main idea of this passage?A．Opera is famous for its long history.B．Opera is only performed for rich people.C．Opera companies are trying to keep opera alive.D．Young people are not interested in opera.69．The underlined phrase in the second paragraph means________.A．breaking up the old rulesB．changing the dressesC．making the audience at easeD．advertising themselves70．The San Francisco Opera employs students in order to________.A．celebrate its 75th anniversaryB．reduce the costC．attract young peopleD．make Cinderella

Can trees talk？ Yes，but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago， researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars（毛虫）changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing， the tree sent out a special smell---a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty. Communication，of course，doesn't need to be in words. We can talk to each other by smiling，raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs，sounds，and movements. Bees dance their signals， flying in certain patterns that tell other bees where to find nectar（花蜜）for honey. So why shouldn't trees have ways of sending message？（1）It can be concluded from the passage that caterpillars do not feed on leaves that ____ .A. have an unpleasant tasteB. are lying on the groundC. bees don't likeD. have an unfamiliar shape（2）The willow tree described in the passage protected itself by ____ .A. growing more branchesB. changing its leaf chemistryC. communicating with birds and beesD. shaking caterpillars off（3）According to the passage， the willow tree was able to communicate with other trees by ____ .A. changing the colour of its trunkB. giving off a special smellC. dropping its leavesD. waving its branches（4）According to this passage， bees communicate by ____ .A. making unusual soundB. touching one anotherC. smelling one anotherD. making special movement

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. [共5题](1)What kind of manager is needed in present international business and foreign investment? [本题2分]A. The man who represents a large multi-million-dollar corporation. B. The man with knowledge of foreign languages and skills in cross-cultural communication. C. The man who is wealthy and impersonal. D. The man who can negotiate with his foreign counterparts.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
