1. Technology and our Life  The 20th century saw many great inventions, such as airplanes, motion pictures, television, telephone, computer, the Internet, to list just a few. Each of these inventions bears witness to the amazing advancements in technology in the past century. These inventions mads our lives much easier and much more enjoyable.  However, progress in technology is always a double-edged sword. People invented pesticides to kill pests but pesticides can pollute the environment by entering the water supplies and harming birds that eat the dead insects. Cell phone has greatly facilitated communication yet it has been proved that it poses danger to users ’ health. What ’ s more, cell phones often go off during movies, concerts, classes, meetings, and libraries and create public nuisance. Automobiles have become an indispensable tool to the modern man but they consume great amounts of fuel, and create enormous environmental problems. Also, many people are killed in car accidents every year. Internet links tens of millions of people around the world but people are so addicted to the Internet today that they don ’ t go out and do exercises.

During World War Ⅱ when Hitler was nearly occupying the whole of Europe, and many people thought the end of mankind was drawing near, Winston Churchill responded in his ringing words: “ Let ’ s fight by sea, land, and air, with all our might and with all the strength that God can give us. ” A tit-for-tat struggle was forged, and Hitler was defeated. And now let ’ s hear what Robert Frost said in his poem THE DEATH OF THE HIRED MAN: “ Home is the place where, when you have to go there, they have to take you in. ” Even more terse words are probably ten tow-letter words by William H. johnson when be described his secret of success, “ If it is to be,it is up to me. ”

3.  Many of us tend to use long words to speak our minds, if they say just what we want, that ’ s okay. But if big words make the way dark for those who hear what we say and read what we write, we might as well use small words, like fast friends, they won ’ t let us down. (418 words)
