敲擊鍵盤的聲音也許是現代社會的一種白色噪音，但其實，他們所透露出的信息比疏忽的打字者意識到的要更多。通過簡單分析擊鍵聲音的錄音，計算機專家們現在就能夠準確無誤的解析出一篇通過鍵盤輸入的文字的腳本，甚至包括輸入的密碼。以其他計算機比起來，這個過程簡單很多，僅僅需要一個便宜的麥克風和一臺電腦。

　　【參考譯文】Clattering keyboards may seem the white noise of the modern age, but they betray more information than unwary typists realize. Simply by analyzing audio recordings of keyboard clatter, computer scientists can now reconstruct an accurate transcript of what was typedincluding passwords. And in contrast with many types of computer espionage, the process is simple, requiring only a cheap microphone and a desktop computer.

　　不可否認，幾乎沒有哪項科學發明對我們的生活產生的影響比得上電視的發明和改進給我們帶來的好處。它是一種電子視聽媒體，是大量信息的重要來源，讓我們不出家門就可以看到各種各樣關于比賽、音樂會以及發生在世界各地的事件的現場報道;人們還可以看到大量花樣百出的特別節目。例如：世界風景、風俗和文化、神奇海底和龐大宇宙的壯觀景象等。所有這一切都在最大程度上豐富了我們的生活和知識。

　　【參考譯文】Admittedly, there is rarely any other technological invention having such a great　impact on our life as the invention and revolution of television. It is a kind of electric　audiovisual media a source of abundant information, which gives people easy access to　various live reports about games, concerts, and affairs occurring all over the world, as well as　a vast variety of special programs, such as programs about worldwide scenery, custom and　culture, the spectacular sight in mysterious seafloor and colossal cosmos, etc. All of them　enrich our life and broaden our knowledge to a significant degree.
