如今，幾乎一半的個人電腦仍然沒有與網絡連接。降低通訊費用以及簡化軟件可以把這些人和網絡連接起來。而這又將使我們更接近讓網絡生活方式成為所有人的生活方式的臨界點。人們低估硬件和軟件將會改進到何種程度。比如，屏幕技術方面?，F在我在20 英寸的液晶顯示器上發(fā)電子郵件。雖然現在它還不能以合理的價格購得，但是兩年后將可以。十年后，更高清晰度的20 英寸液晶顯示器將成為普通的事物。電視和個人電腦之間的界限將變得模糊，因為甚至是連著有線或衛(wèi)星的電視機上的盒子中都會有比如今最昂貴的個人電腦更強大的的處理器。實際上，你的電視將成為一臺電腦。

　　與網絡的交流也將得到改善，這使人們更容易參與其中。如今，搜索網絡時輸入的關鍵詞總會搜出太多的選項讓你選擇，而其中很多項與你所找的內容無關。當你想知道現有的最快的計算機芯片時，卻得到在快速通道上運送的薯片的信息。將來，我們可以對著電腦講話或者往電腦中輸入句子。如果問芯片的速度，結果將是關于電腦，而不是土豆。語音識別也意味著你能夠打電話給電腦詢問是否有新的信息，或者查詢航班和天氣。

　　預計要花上十多年時間這些變化才會發(fā)生可能太悲觀了。我們經常高估兩年內能做到的事，而低估十年之內能做的事。不久以后，網絡會像汽車一樣成為一種生活方式。

　　Directions:

　　The following paragraphs are given in a wrong order for Questions 21-25, you are required to reorganize these paragraphs into a coherent article by choosing from the list A-G to fill in each numbered box. The first and the last paragraphs have been placed for you in Boxes. Mark your answers on ANSWER SHEET 1. (10 points)

　　[A] If you are in the frightening position of waking in the middle of the night and think you can hear an intruder, then on no account should you approach the intruder. Far better to telephone the police and wait for help.

　　[B] But what could happen if, in spite of the aforementioned precautions, a burglar or intruder has decided to target your home. Windows are usually the first point of entry for many intruders. Downstairs windows provide easy access while upstairs windows can be reached with a ladder or by climbing up the drainpipe. Before going to bed you should double-check that all windows and shutters are locked. No matter how small your windows may be, it is surprising what a narrow gap a determined burglar can manage to get through. For extra security, fit window locks to the inside of the window.

　　[C] The first fact is that burglars and other intruders prefer easy opportunities, like a house which is very obviously empty. This is much less of a challenge than an occupied house, and one which is well-protected. A burglar will wonder if it is worth the bother. There are some general tips on how to avoid your home becoming another crime statistic. Avoid leaving signs that your house is empty. When you have to go out, leave at least one light on as well as a radio or television, and do not leave any curtains wide open. The sight of your latest music center or computer is enough to tempt any burglar.

　　[D] A sobering fact is that not all intruders have to break and enter into a property. Why go to the trouble of breaking in if you can just knock and be invited in? Beware of bogus officials or workmen and, particularly if you are elderly, fit a chain and an eye hole so you can scrutinize callers at your leisure. When you do have callers never let anybody into your home unless you are absolutely sure they are genuine. Ask to see an identity card, for example.

　　[E] What about entry via doors? Your back door and patio doors, which are easily forced open, should have top quality security locks fitted. Even though this is expensive it will be money well spent. Install a burglar alarm if you can afford it as another line of defence against intruders.

　　[F] A recent survey of crime statistics shows that we are all more likely to be burgled now than 20 years ago and the

　　police advise everyone to take a few simple precautions to protect their homes.

　　[G] Never leave a spare key in a convenient hiding place. The first place a burglar will look is under the doormat or in a flower pot and even somewhere more imaginative could soon be uncovered by the intruder. It is much safer to leave a

　　key with a neighbour you can trust. But if your house is in a quiet, desolate area be aware that this will be a burglar s dream, so deter any potential criminal from approaching your house by fitting security lights to the outside of your house.
