Which of the following is not true？

A．Navigating the Superhighway without the right knowledge and tools is a waste of time.

B．There are not many ways so far to use the Internet to retrieve information.

C．Java is a useful program.

D．There are various levels of knowledge about cars.

听力原文： Sometimes the simplest of tools is the most useful. Consider, for example, the ruler. A ruler is mainly used to measure and draw straight lines on flat surfaces. It does not have a great many uses, especially since parents and teachers have given up trying to instruct children through spankings. Some rulers are clear and can be seen through, some made of metal, and some provide both metric and American measurements. People carry them ill their shirt pockets, briefcases, or purses, to have them available for use any time.

Of course, the ruler is not only simple but very useful device. Consider, for instance, the pencil, the doorknobs and hinges, and glass. Jet planes and computers are fine, but not necessary for survival. Who, on the other hand, could survive without the simple tools mentioned here？

A．Simple tools are necessary for mankind.

B．Simple tools can be very complicated.

C．Simple tools are forgotten in the modern society.

D．Modern technology are needed in the modern society.

Materials andTools for Language Learning

__① __ The range of materials and tools avaiable to help you with your language studies ishuge from dictionaries to language courses. All of them can help you in different ways, and theappropriate use of these materials and courses will make your language learning much easier andmore effective.

__② __ Possibly the most useful tools there are for learning a language are dictionaries. Dictionaries come in a number of formats including bilingual monolingual, illustrated, electronicand online. Bilingual dic tionaries are perhaps the most useful ones for beginners andinterme-diate learners while monolingual dictionaries, which are designed for native speakers,arealso useful for advanced learners. Pocket dictionaries are good for quick reference and easy tocarry around. Larger dictionaries are better if you want more definitions, examples of us age,andinformation about pronunciation, and grammar. Electronic dictionaries are available as handheldunits or assoftware. Handheld onesare portable, easyand quick to search, and often provide otherfunctions such as, text-to-speech, voice recognition and speech synthesis organizers, addressbooks. They tend to be rather expensive though. Software dictionaries offer many of the samefunctions, and canbe used on computers, and mobile phones.

__③ __ The traditional courses tend to consist of textbooks containing dialogues,Exercisesnotes on grammar, and maybe cultural information. Accompanying cassettesCDs and/or mp3s areoften available Most such courses are intendcd for complete beginners or people with onlyminimal knowledge of the language. Intermediate and advanced-level courses are available forsome of the more popular languagessuch asFrench,C, erman Italian and Spanish.

__④ __ Audio courses usually consist solely of cassettesor CDs though some may alsoinclude a limited amount of printed material. All dialogues exercises,instructions and explanationsare recorded and the focus of these courses is teaching you to understand and speak the language. They are very good at teaching you authentic pronunciation and a manageable amount ofvocabulary.

__⑤ __ Various computer-aided coursesare available on CD-ROMs and DVDs. Each courseis different but they generally include dialogues audio exercises and tests. Some also includephrasebooks,dictionaries, videos, gamesandprovide online and/or telephone support.

A．What is the function of audio courses？

Section D

Robots are useful in exploring space because they can work in the conditions which exist in space. Such robots usually look like boxes with wheels. Though these robots are useful, however, they are extremely expensive—they break easily and they cannot do very many tasks. Because of these problems, scientists have been working on a new and unusual kind of robot. These new robots will look and move like snakes, so they have been given the name ‘snakebots'.

The way a snake is shaped allows it to do special things, such as getting into very small spaces, like cracks in rocks. Snakes can also push themselves underground, and climb up different kinds of objects, like rocks and trees. Such abilities account for the usefulness of robots designed like snakes, because they will be able to do these things, too. Such robots would be much more effective than regular robots with wheels. Wheeled robots easily get stuck and fall over, but snakebots would not have these problems. They could go almost anywhere and so would be useful for exploring the different environments of other planets. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.

How do you make a robot shaped like a snake？ A snakebot is put together like a chain, made of about thirty parts, or modules. Each module is basically the same—they all contain a computer and a wheel to aid movement. The computer in the ' head' of the snake makes the modules work together. If one module fails, another can easily take its place. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, each module can work apart from the rest if necessary.

The snakebot design is much simpler than that of most common robots. Thus, snakebots will be much less expensive to build. One of the robots sent to Mars cost over a hundred million dollars to build. However, snakebots cost as little as a few hundred dollars to make and could therefore save enormous amounts of money on future space missions. With their versatility and affordability, snakebots will be the way of the future; at least as far as space robots are concerned.

Summary:

It is much easier to send robots, rather than people, into space, but scientists have found that robots with wheels are not the most【46】______ones. This is because there are many problems associated with today’s robots: they are very expensive, they【47】______and cannot do many tasks. In fact, for exploring places with lots of obstacles to go over or under,【48】______work better than wheeled robots. They are made of separate parts, or【49】______, each of which is actually a robot in itself. Snakebots can go almost anywhere and do many different kinds of tasks. It looks as though robots shaped like snakes will be the way of the future owing to their【50】______.

Generally, data mining (sometimes called data or knowledge discovery) is the process of analyzing data from different perspectives and (1) it into useful information information that can be used to increase revenue, (2) costs, or both. Data mining software is one of a number of analytical tools for analyzing data. It (3) users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational databases.

Although data mining is a (4) new term, the technology is not. Companies have used powerful computers to sift through volumes of supermarket scanner data and analyze market research reports for years. However, continuous innovations in computer processing power, disk storage, and statistical software are dramatically increasing the accuracy of analysis while driving (5) the cost.
