對比法或比較法(comparison & contrast)
將同類的事物按照某種特定的規(guī)則進(jìn)行比較分析是一種常用的思維方法。通過對比,更容易闡述所述對象之間的異同和優(yōu)缺點(diǎn),例如:
The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nicer cells in the human brain. A problem that might take a human being a long time to solve can be solved by a computer in one minute.
在這段文字上, 作者為了突出電子計(jì)算機(jī)運(yùn)行速度之快,首先將它與人腦進(jìn)行了比較, "-- a thousand times faster than --" ;而后,又將這一概念具體到了 "a problem"上,通過對比使讀者從 "-- a long time -- in one minute"上有更加直觀的認(rèn)識。
常用于對本法或比較法上的過渡連接詞有:than, compared with等。
