　　Nowadays, with the rapid development of IT, cell phones play a more and more important role in people’s life. But, like everything else, they have both favorable and unfavorable aspects.
　　First ,it’s useful. As a wireless mobile telephone ,it’s easy and handy to carry it wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people’s life. Second, it’s convenient. Whenever one meets trouble or something urgent, one can make a call immediately. Most important of all, it’s a very helpful companion. With a multifunction cell phone in hand, one can easily get on the net, browsing the useful information, conducting e-commerce and doing whatever one can do via Internet.
　　However, just as everything has two sides, the cell phone also has many disadvantages,. To begin with, it’s expensive to buy and costly to pay the bills, esp. that of global service. To make matter worse, it’s also easy to lose and costly to get it repaired. Worst of all, it’s not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it’s alleged the micro-waves in it might do harm to people’s health.
　　In my opinion, with its expenses greatly reduced after China’s entry into the WTO,. Someday most of them will be developed into new Internet-enabled mobile phones, which will be as useful as pocket computers. And I believe its advantages will not only offset its disadvantages, but also far outweigh them.

　　范文賞析：
　　這是篇議論文，文章開篇入題，一步到位。先由手機(jī)的重要性直接引入議題，手機(jī)雖在人們生活中越來越重要，但也是利弊摻半，并以此承上啟下，自然過渡。
　　接著在第二段文章論述了手機(jī)的益處：方便、快捷、便于攜帶，可以用它上網(wǎng)等等。隨后，作者用“世上任何事物都是一分為二的”完成段落的過渡，進(jìn)而引出手機(jī)的弊端，如自身價(jià)格昂貴、費(fèi)用難以承受、易于丟失、有時(shí)因音量過小不清楚等等。
　　最后，權(quán)衡利弊，通過“In my opinion”作者亮出自己的觀點(diǎn)：隨著中國入世手機(jī)費(fèi)用的下降，“利”會(huì)遠(yuǎn)遠(yuǎn)超過“弊“，且手機(jī)未來的趨勢(shì)會(huì)向掌上電腦型發(fā)展。
