下面老师给大家举一个例子。来看看你能分辨出下面的段落说了几个重要信息吗?
Ok, a lot of people think of earths orbit around the sun as being perfectly circular, as smooth and as regular as, say, the way that hands move on a well-made watch, but it just doesnt work that way. You are probably aware that the earths orbit around the sun, it is not shaped like a perfect circle. It is more of an oval, it is elliptical. But the shape of this orbit isnt consistent; it varies over time, over a period of about a thousand years. Sometimes it is a little more circular, sometimes it is more elliptical. And when earths orbit is more elliptical, earth is actually closer to the sun during part of the year. Which makes earth, and in particular, the northern hemisphere, warmer. And why is that important? Well, because most of the planets glaciers are in the northern hemisphere, and if it gets too warm, then glaciers will stop forming. And weve already talked about how that affects earths overall temperature。
其实别看这个段落这么长,其实它只传达了三个重要信息,也就是说归纳起来只有三个重点,其余的部分都是对重点的解释。
第一个信息:地球绕太阳的轨道是椭圆形的。原文用了5句话来反复解释这个信息,而且虽然出现了相对生僻的单词oval,但出题者怕考生听不懂又用了一个比较常见的elliptical来解释。如下:
