“改变”是SAT写作中的常见话题，关于这个话题有哪些素材事例可以使用呢？本文将介绍技术变革给人们的生活带来的影响，其中的一些变化可难以称得上是有利。
Theme: Change
Thesis: The world isn’t always changing for better.
Subject 1: Environment pollution & Economic inequality
Since the Industrial Revolution, our environment has been in imminent danger. For example, a dramatic summer drought helped public focus their attentions on the greenhouse effect, a general warming of temperature on the Earth, which is caused by an increase in atmospheric carbon dioxide released by burning fossil fuels like coals, gasoline products, and rapid deforestation. Along with the rapid technology advance is the emergence of acid rain, ecological wasteland, and natural disasters, such as flood and hurricane. Not only to environment, but also to some people, changes in today's seemingly progressive world are not always good. The booming America saw a growing economic inequality. In 2004, the number of millionaire household in America increased by 14% as the number of people living below the poverty line rose to about 37 million, including 15 million children. The annual budget passed by Congress in 2005 severely cut programs essential to struggling families, including child assistance and medicaid funding for the poor. Left in such desperate condition, the poor could hardly appreciate these changes.
Subject 2 : Technology changes
Detail: In a culture where emails, cell phones, and internet chat room have become everyday modes of communication, we are on the verge of breaking down all barriers to the complete and constant transfer of information. But if we seem to be moving toward unfetter union, we could also be seen more isolated as individuals than we have ever been before. Changes in technology definitely make our lives easier, as shopping at home becomes easier than driving to the store, as meeting people online eliminates the need to spend a lot of time traveling, and as faxing someone a blueprint gets rid of necessity of meeting to disscuss a plan. However, the very techonology that purports to make connections and bring people closer together is helping them drift apart. One can absolutely recall some scenes where you were sitting alone in your bedroom busily talking to someone on msn while rejecting the proposal to shop with your families, or where you were having lunch with friends while talking to someone else on your cellphones. All these convenient technologies including online services that prevent us from going out and meeting a real person, and cellphones that reduce the real human interaction, do not necessarily make us better.
以上两个例子可以在与成功相关的作文话题中使用。但是切忌一字不落地背下例子然后在作文中全篇套用，考生需要注意将例子和自己的论点相结合，在叙述中突出重点。
