托福口语必背经典文章：电力ElectricityThe modern age is an age of electricity. People are so used to electriclights, radio, televisions, and telephones that it is hard to imagine what lifewould be like without them. When there is a power failure, people grope about inflickering candlelight, cars hesitate in the streets because there are notraffic lights to guide them, and food spoils in silent refrigerators.Yet, people began to understand how electricity works only a little more thantwo centuries ago. Nature has apparently been experimenting in this field formillion of years. Scientists are discovering more and more that the living worldmay hold many interesting secrets of electricity that could benefithumanity.All living cell send out tiny pulses of electricity. As the heart beats, itsends out pulses of record; they form an electrocardiogram, which a doctor canstudy to determine how well the heart is working. The brain, too, sends outbrain waves of electricity, which can be recorded in an electroencephalogram.The electric currents generated by most living cells are extremely small – often so small that sensitive instruments are needed to record them. But in some animals, certain muscle cells have become so specialized as electricalgenerators that they do not work as muscle cells at all. When large numbers of these cell are linked together, the effects can be astonishing.The electric eel is an amazing storage battery. It can seed a jolt of as muchas eight hundred volts of electricity through the water in which it live. ( An electric house current is only one hundred twenty volts.) As many as four-fifths of all the cells in the electric eel’s body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body.2020 考研英语：真题经典长难句必背(一)一篇考研阅读理解文章中一般会出现3-5句长难句，而且还至少有一道针对长难句理解的考题，因此很有必要熟悉长难句的种类以及它们各自的重点。

Without electricity…., we could not cook food, wash clothes and watch TV.Generally speaking, there are three ways to save electricity…. First, we should produce electricity-saving home appliances. Second, remember to turn off the light when you leave a room. Finally, we should change our way of life to choose alow-carbon life. Avoid as much as possible the “artificial life” powered by electricity. All in all, electricity will bring us bright, make our life colorful.Competition and cooperationCompetition is now a common phenomenon in our society. We compete when we play games, we try to do better than others in our study, and we often compete for jobs, customers, money, and so on so forth. To some extent, we can say, competition is an important motive force of our life.We often find competition and cooperation occurring at the same time. For example,during a football game, one team is competing with the other, but each member of the team must cooperate with his teammates. In most ca ses, we can’t compete without cooperation. Therefore, competition and cooperation are equally important in our life. While we are advocating competition, we can’t forget cooperation. In modern society, cooperation plays a very important part, because most work is finished with and through other people. So we must combine competition with cooperation in order to reach the “double win” goals successfully.学位英语范文：网络How Will Our Life Go on without Internet?1. 网络提供给了人们丰富多彩和便捷的生活2.很多人开始感觉离开网络寸步难行3.你对网络依赖症的看法●审题概述●本文是一篇论述你对网络与人们生活关系的文章。
