题目列表(包括答案和解析)
Third – generation mobile phones, known as 3G, are the next big step for the electron industry. Data spec in 3G networks are much quicker than present technology. This means users can have high-speed Internet access and enjoy video and CD-quality music on their phones.
“Mobile data is not a dream; it’s not an option but a requirement,” said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.
With 3G, you can forget about text messages telling you yesterday’s news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.
Face-to-face video calls
And don’t worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset.
However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.
Many European countries have already launched the service. In May 2000 the US Government issued five license to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.
International telecom companies can’t wait to sell 3G in China, the world’s largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.
“We need to create a pool of 3G customers before the large-scale commercial launch of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued late next year.”

Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels—petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don’t find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be?
Energy from the wind
All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy.
Energy from water
When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.
Energy from the earth
There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world.
Energy from the sun
Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy.
【小题1】What does this passage mainly talk about?
| A．Advantage of the energy from nature. |
| B．The future of the energy. |
| C．Scientists have been working hard to research other kinds of energy. |
| D．Energy is the most important power in the word. |
| A．energy can do everything for people |
| B．all the energy causes pollution |
| C．the new kinds of energy are badly needed |
| D．scientists have found other kinds of energy for the future |
| A．Try to use water energy more though it costs a lot. |
| B．Each natural energy has its own advantages and disadvantages. |
| C．Solar power is environmental. |
| D．Wind power is the cheapest but we can’t get. |
| A．In order to protect our environment, we should try other kinds of energy. |
| B．All scientists in the world will unite to find energy. |
| C．People in modern life use energy every day. |
| D．Energy changes people’s lives. |
For the person keeping a journal, whatever he experiences and wants to hold he can write down. But to get it down on paper begins another adventure. For he has to focus on what he has experienced, and to be able to say what, in fact, the experience is. What of it is new? What of it is remarkable because of associations in the memory it stirs up? It is a good or bad thing to have happened? And why, specifically? The questions multiply (增多) themselves quickly. As one tries to find the words that best represent this discovery, the experience becomes even clearer in its shape and meaning.
Beyond the value of the journal as record, there is the value of the discipline it teaches. The journalist begins to pay closer attention to what happened to and around himself. He develops and sharpens his skills of observation. He learns the usefulness of languages as a means of representing what he sees, and gains skill and certainty in the expression of his experiences. To have given up one’s experience to words is to have begun marking out the limits and potential of its meaning. In the journal that meaning is developed and clarified (澄清、阐明) to oneself. When the intention of the development of that meaning is the consideration of another reader, the method of the journal redirects itself and it becomes the essay.
【小题1】According to the author, keeping a journal is good for ________.
| A．observation and expression |
| B．certainty and discipline |
| C．experience and adventure |
| D．consideration and development |
| A．develop the usefulness of language |
| B．develop his memory |
| C．clarify the consideration to everyone |
| D．have a thorough understanding of his experience |
| A．The journalist can express what has happened. |
| B．A journal can serve as a record of the past happening. |
| C．The journalist must be able to observe closely. |
| D．Writing helps develop the consideration of others. |
| A．how to write a journal |
| B．the expressions of a journal |
| C．the values of keeping a journal |
| D．how to solve the problems in a journal |
