ACT写作3大步骤：规划-写作-修改

　　第三阶段：修改(2-4分钟)

　　先看一下完整的ACT写作范文：

　　[1] From the simplest system of pulleys and ropes in ancient Greece to the most complex supercomputer in the world today, machines have had (and continue to have) a profound influence on the development of humanity. While some argue that machines have a negative impact on us, the increasing prevalence of intelligent machines in the world challenge us to change long held beliefs about our limitations and to continue forward to new and even more advanced possibilities.

　　[2] One common argument against the increased presence of machines in our day-to-day lives (seen in Perspective One) is that machines leach away at our basic humanity. I found this to be true in my own life as a result of witnessing many a phone conversation between my mother and an automated telephone menu. For whatever reason, she consistently has issues with the menus that try to verify her date of birth. The automated system never understands what she says (possibly because of her accent), and asks her to input the numbers via her keypad; of course, my mom's smartphone is so smart that the screen turns off while she is on a call, making it impossible for her to follow the automated phone system's instructions. By the time the system gives up and routes her to speak to a "human representative," my mother is often so frustrated that she is far from courteous and respectful to that person. Despite my mother's understandable frustration with automated phone systems, however, overall the benefits outweigh the costs. Providing people with the option to submit prescriptions or ask about store hours through an automated menu frees up customer service representatives to answer questions machines are incapable of addressing. In addition, the recordings of angry phone calls (where customers are not courteous, respectful, or tolerant of other humans) are used to improve the phone menus to make them more user-friendly. Thus, the momentary disrespect toward other humans caused by machines is more than compensated for by the positive effects of those same machines.

　　[3] Another school of thought, exemplified by Perspective Two, argues that the main utility of machines is their ability to perform repetitive tasks more precisely and more efficiently than humans, which leads to a more prosperous and progressive world for everyone. In auto plants around the world, robots build cars on assembly lines. Instead of having to pay a human employee a yearly salary, invest time in training that employee, and worry about liability should that employee be injured, manufacturing plants can now make a one-time purchase of an intelligent machine that will perform that same job at higher levels of precision. This leads to a more prosperous world for the manufacturers, as they are able to invest less money to get a better product. This perspective is fine as far as it goes, but is limited in its consideration of the implications. Robots can not only work in place of humans, but can also work cooperatively with humans to a greater results than either could have hoped for alone. This can be seen in highly complex and delicate surgeries, where a surgeon controls robotic microtools to perform operations that even ten years ago would have been unimaginable and impossible.

　　[4] I agree with Perspective Three that the true impact of intelligent machines in our lives is that they challenge us to re-think our preconceived notions of what people can do or become in the future. A final example of this is brain-computer interfaces, or BCIs. Humans are able to manipulate computers with their brains via electrodes that are either implanted in their brains or attached (temporarily) to their heads. With these intelligent machines, formerly paralyzed people who had no hope of communicating with others are able to transcend their physical limitations by concentrating to form words out of keyboards on the computer screens. In addition, BCIs have captured the interest of people from all different backgrounds and are being applied to non-scientific fields like music to create new, previously unimagined instruments that react to people's thoughts, adding a new dimension to an ancient art form. Truly, intelligent machines are providing the impetus not just for greater efficiency, but for greater accomplishments.

　　[5] In conclusion, rather than taking away from ourhumanity, intelligent machines actually help us to move forward as a species to achieve new, previously unimagined possibilities.

　　经过最后的2-4分钟，我们可以查出几个小错误，例如：

　　Paragraph 1, Sentence 2: [subject/verb agreement; change is bolded]

　　The increasing prevalence of intelligent machines in the world challenges us to change long held beliefs about our limitations and to continue forward to new and even more advanced possibilities.

　　或者用更简明优美的句子表达自己的观点：

　　Paragraph 2, last sentence

　　Thus, the momentary disrespect toward other humans caused by machines is more than compensated for by the positive effects of those same machines.

　　We can change it to:

　　Thus, any momentary disrespect my mom might show to a customer service representative (as a result of frustration with the automated system) is more than compensated for by the positive effects of those same machines.
