Study the following graph carefully and write an essay in which you should
1) analyze the graph, and
2) give your comments on the trend.

In recent years there has been a dramatic rise in the cell phones, which are now essential to millions of people as a convenient form of communication. In 2004 the number reached 315,000,000, with an average annual increase at 57,500,000.

Some people can now no longer imagine life without their cell phones. The fact that they are so popular proves that they are useful and convenient. Cell phones enable people to easily and quickly communicate with one another; wherever you are, you can instantly reach somebody. Cell phones eliminate the　trouble of not being able to meet someone in person, and therefore increase business's efficiency.

Mobile phones necessarily also harbor disadvantages. The radiation such phones emit is hazardous to one's health. Furthermore, if people become too reliant on the use of cell phones, our face to face skills may decline. Any new invention has its drawbacks, and such negative aspects cannot always diminish its popularity. Despite the negative effects of television, for example, the number of people who own televisions continues to grow at a tremendous rate. This is also the case with mobile phones. People won't stop eating just because of the risk of choking. In addition, the swift development of science and technology will likely eliminate the hazards cell phones may cause. One can safely predict, therefore, that with the introduction of new techniques, mobile phones will have more applications and become even more appealing to customers.

近年來，手機有了飛速的增長。對數(shù)以百萬計的人來說，作為便捷的通訊工具手機是生活中必不可少的。到2004年，手機的數(shù)量達到3.15億，平均每年增長了5750萬用戶。

有些人現(xiàn)在已經無法設想沒有了手機的生活會是什么樣子。手機如此普及的事實證明了它們的實用和方便。手機使人們能夠簡單快捷地相互溝通，無論身處何地，都能馬上聯(lián)系上。手機解決了需要交流時卻無法見面的問題，因而也增加了商業(yè)活動的效率。

使用手機也不可避免地存在弊端。手機發(fā)出的輻射對健康不利。而且，如果人們過于依賴手機，那么我們面對面交往的能力會下降。每個新發(fā)明都有它的缺點，但這些消極方面并不會影響它的普及。比如電視，盡管有很多負面作用，但擁有電視的人數(shù)還是繼續(xù)以極高的速度增長。這種情況也適用于手機。人們不會因噎廢食。而且，科技的飛速發(fā)展有希望消除使用手機所帶來的風險。所以，可以有把握地預言，隨著新技術的采用，手機會有更廣的用途，而且會對消費者更有吸引力。
