托福阅读练习材料之燃煤电厂

燃煤电厂

The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand for a cheap, readily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations. (which were set up at the end of the nineteenth century by Edison himself). As more power plants were constructed throughout the country, the reliance on coal increased throughout the country, the reliance on coal increased.

World War, coal-fired power plants had a combined in the United States each year. In 1986 such plants had a combined generating capacity of 289,000 megawatts and consumed 83 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas, coal-fired power plants could well provide up to 70 percent of the electric power in the United States by the end of the century.

Yet, in spite of the fact that coal has long been a source of electricity and may remain on for many years(coal represents about 80 percent of United States fossil-fuel reserves), it has actually never been the most desirable fossil fuel for power plants. Coal contains less energy per unit of weight than weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. Since the late 1960’s problems of emission control and waste disposal have sharply reduced the appeal of coal-fired power plants. The cost of ameliorating these environment problems along with the rising cost of building a facility as large and complex as a coal-fired power plant, have also made such plants less attractive from a purely economic perspective.

托福口语怎样快速改善发音问题？
托福口语备考，很多同学选择的备考方式是跟读。跟读的确能够帮助大家提升口语熟练度，但缺乏重点，只是逐字逐句地跟读能够起到的学习效果也是有限的。托福口语备考需避免盲目跟读，一说到练托福口语，可能不少考生都会把跟读的练习方式当成一种比较常见的学习提升方法。但跟读训练也需要讲究一定的技巧和注意事项，否则收效并不见得会让考生满意。下面新航道小编就来为大家做具体介绍。

托福口语怎样快速改善发音问题？

盲目跟读无法纠正托福口语发音

托福考生总是纠结这样一个问题——练了半天但就是没有多少效果，考托福口语时依然我行我素的发着奇怪的音，世界上最痛苦的事莫过于此。笔者也曾经同样为之烦恼过，起初练习语音的方法非常简单，就是到书店买本书，然后跟着磁带盲目地读，结果是我自己一个音，磁带一个音，怎么模仿都不像。当时喜欢将一个一个音标和例词抄在本子上，走到哪里读到哪里。如apple、mad、sad、had、cat、Jack…但丝毫没见进步。

为何?道理其实很简单，我们平时说话都以句子为单位而不以单词为单位。比如到了美国见到一个卖水果的，人家问：“What can I do for you?” 我们不能简单地回答成“Apple”, 而是应该说成“I’m lookin’for some apples.” 因此孤立地练习音标和单词具有欺骗性——孤立地读音标或单词都会好听，一旦放在句子中便无法体现。

托福口语备考纠正句子发音才是提升重点

衡量语音好坏的唯 一标准是句子的发音!只有摆对方向才能学有所用。那么如何去练习句子的发音呢?给大家介绍句子读法“三剑客”：连读、失去爆破、弱读。比如on it不应读成【on】【It】，而应读成【o】【nI】【t】, 同样，first time中的两个【t】应读成一个【t】;美国总统奥巴马在2008年芝加哥获胜演说中读“must be”中的【t】不读出声，读“could be”中的【d】彻底消失。因此，与其将大量精力浪费在一个孤立的音标上，倒不如学习如何读好句子，毕竟这才是根本。

关于托福口语备考中的跟读练习以及如何纠正句子发音，小编就为大家介绍到这里，希望能够让各位同学有所进步和提升。
