托福阅读：掌握两个要点突破托福阅读压轴题（下）

掌握两个要点突破托福阅读压轴题（上）为我们讲解了托福阅读解析总结句，话不多说，掌握两个要点突破托福阅读压轴题（下）又为我们讲解了什么呢？我们一起来看看新航道老师的托福阅读干货分享吧。

解析段落首二末

在核心段落中，分论点一般会出现在段落的第 一句话、第二句话、或者是最后一句话，也就是所 谓的‘首二末’三句话才是我们应该去直接阅读的内容。

当然，在实际的阅读过程中，我们要通过自 己敏捷的思考，快速找出首二末这三句话中最能代 表段落主旨的一句话并进行归纳概括。

1、以 He Development of Steam Power  一文举个例子，我们择出文中第二段：

As this early energy crisis grew worse, Britain looked toward its abundant and widely scattered reserves of coal as an alternative to its vanishing wood. Coal was first used in Britain in the late Middle Ages as a source of heat. By 1640 most homes in London were heated with it, and it also provided heat for making beer, glass, soap, and other products. Coal was not used, however, to produce mechanical energy or to power machinery. It was there that coal's potential wad enormous.

句话交待的很清楚，英国期待使用 coal 作 为 wood 的替代物。直接再看最后一句话，coal 的潜 力很大。因此，第二段的核心主旨即可概括为 coal 可以取代 wood。

2、再看该文的第三段

As more coal was produced, mines were dug deeper and deeper and were constantly filling with water. Mechanical pumps, usually powered by hundreds of horses waling in circles at the surface, had to be installed. Such power was expensive and bothersome. In an attempt to overcome these disadvantages, Thomas Savery in 1698 and Thomas Newcomen in 1705 invented the first primitive steam engines. Both engines were extremely inefficient. Both burned coal to produce steam, which was then used to operate a pump. However, by the early 1770s,many of the Savery engines and hundreds of the Newcomen engines were operating successfully, though inefficiently, in English and Scottish mines.

句话说矿井被挖的越来越深，我们再看最后 一句话，出现了2个人发明的engine可以用来挖矿， 虽然效率很低。两句话相结合，这一段的主旨应该是 为了满足挖矿的需要，Savery 和 Newcomen 发明了效 率低的 engine。

3、我们接着看第四段

In the early 1760s, a gifted young Scot named James Watt was drawn to a critical study of the steam engine. Watt was employed at the time by the University of Glasgow as a skilled crafts worker making scientific instruments. In 1763: Watt was called on to repair a Newcomen engine being used in a physics course. After a series of observations, Watt saw that the Newcomen's waste of energy could be reduced by adding a separate condenser. This splendid invention, patented in 1769, greatly increased the efficiency of the steam engine. The steam engine of Watt and his followers was the technological advance that gave people, at least for a while, unlimited power and allowed the invention and use of all kinds of power equipment.

这段话句说瓦特开始研究 steam engine，最 后一句话的意思是瓦特的蒸汽机取得了很大的突破， 给我们带来了无穷的能量和其他设备的发明。中间的 内容无需多看，我们也可以知道这段话重点是瓦特改 良了蒸汽机，取得了成功。 熟练掌握直接看段落首二末的方法，可以在读文 章和解题的时候，帮我们节省大量的时间，也是快速 解决文章总结题的关键所在。

以上就是我对托福阅读文章总结题的理解，希望大家能在托福阅读考试的备考上能够做到有的放矢，多加积累，取得理想的成绩。
