如何挖掘托福阅读段的主题

托福阅读时，我们可以根据段落中出现的一些信号词(Signal Words)来判断句子与句子之间的关系，掌握段落发展线索，来调整阅读速度，提高阅读质量。下面为您整理托福阅读段中经常遇到的信号词，希望对您有所帮助。 托福阅读信号词1.显示相同信息的信号词

There has been an upsurge of interest in chamber music. Likewise opera is receiving a boost from increased record sales。

“likewise”这一信号词显示了前面所提到的idea后面还要再一次出现。因此，阅读时见到这样的信号词无须放慢阅读速度。这样的信号词还包括：and, furthermore, more, than, that, also, likewise, moreover, in addition, what is more, for instance, for example

托福阅读信号词2.显示思路转折的信号词

I'd like to go but I'm too busy。

“but”前后是完全不同的信息描述，它向读者显示了作者的思路在这里有了转折。阅读时，碰到这样的信号词我们需放慢阅读速度，以准确获取作者真正想要说明的意思。这类信号词还有：

although, however, on the contrary, but, in spite of, otherwise, despite, nevertheless, yet

托福阅读信号词3.显示因果关系的信号词

As a result of the pilots'strike, all flights have had to be cancelled。

All flights have had to be cancelled as a result of the pilots'strike。

托福阅读信号词4.显示顺序的信号词

Internet speeds communication between companies, among co-workers through video-conferences, and among other individuals. First, media companies use the Internet for online news, or to broadcast audio and video, including live radio and television programs, while individuals use the Internet for communication, entertainment, finding information, buying and selling goods and services. Second,the notion of distance disappears thanks to the Internet. People also enjoy instant messaging to exchange text messages or pictures in real time, with real-time video and sound. Finally, scientists and scholars use the Internet to perform research, distribute lecture notes or course materials to students, they communicate with colleagues, and can also publish papers and articles。

抓住了这样的信号词就把握住了作者叙述的顺序，也就分清了相对独立的论据。这样的信号词包括：

first, second, third, and so on, then, after, before, next, last, afterward, finally

托福阅读信号词5.表示结论/总结的信号词

In conclusion, I would like to say how much I have enjoyed myself today。

词组“in conclusion”前面所提到的一些信息将在这里被归纳总结。读到带有这样的信号词或短语的句子时，应格外留心注意，它们往往会向我们提示相关段落的核心信息。表示结论或总结的信号词和短语还有：

as a result, finally, therefore, accordingly, in short, thus, consequently, in conclusion, so, in brief, in a word

在进行托福阅读时，我们不应把每个句子都孤立开来，而是要把所有的句子连成一个整体，通过准确把握句子与句子之间的逻辑关系来挖掘托福阅读段的主题。
