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.

近年来，手机有了飞速的增长。对数以百万计的人来说，作为便捷的通讯工具手机是生活中必不可少的。到2004年，手机的数量达到3.15亿，平均每年增长了5750万用户。

有些人现在已经无法设想没有了手机的生活会是什么样子。手机如此普及的事实证明了它们的实用和方便。手机使人们能够简单快捷地相互沟通，无论身处何地，都能马上联系上。手机解决了需要交流时却无法见面的问题，因而也增加了商业活动的效率。

使用手机也不可避免地存在弊端。手机发出的辐射对健康不利。而且，如果人们过于依赖手机，那么我们面对面交往的能力会下降。每个新发明都有它的缺点，但这些消极方面并不会影响它的普及。比如电视，尽管有很多负面作用，但拥有电视的人数还是继续以极高的速度增长。这种情况也适用于手机。人们不会因噎废食。而且，科技的飞速发展有希望消除使用手机所带来的风险。所以，可以有把握地预言，随着新技术的采用，手机会有更广的用途，而且会对消费者更有吸引力。
