问题 单项选择题

通常认为左撇子比右撇子更容易出事故。这是一种误解。事实上,大多数家务事故,大到火灾、烫伤,小到切破手指,都出自右撇子。
以上哪项最为恰当地概括了上述论证中的漏洞

A.对两类没有实质性区别的对象作实质性的区分。

B.在两类不具有可比性的对象之间进行类比。

C.未考虑家务事故在整个操作事故中所占的比例。

D.未考虑左撇子在所有人中所占的比例。

答案

参考答案:D

解析:题干只比较了右撇子出事故的人数比左撇子出事故的人数多,就确认左撇子不比右撇子更容易出事故,这个比较显然是不对的。
怎样来比较左撇子与右撇子哪个更容易出事故呢关键是要比较左撇子的事故率和右撇子的事故率。
左撇子的事故率=左撇子出事故的人数/左撇子的总人数
右撇子的事故率=右撇子出事故的人数/右撇子的总人数
只有考虑左撇子在所有人中所占的比例,才能确定左撇子和右撇子的总人数比,进而才能确定左撇子和右撇子哪个更容易出事故。
如果左撇子在所有人中所占的比例明显低于右撇子,那么就不能根据大多数家务事故都出自右撇子,就否定左撇子比右撇子更容易出事故。可见,D项概括了上述论证中的漏洞。

阅读理解

Reading is a good habit, but the problem is, there's too much to read these days, and too little time to read every word of it. There are hundreds of skills to help you read more in less time. Here are two skills that I think are especially good.

Preview--if it's long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.

Here's how to preview.

●Read the first two paragraphs and the last two paragraphs carefully.

●Then read only the first sentence of the other paragraphs.

Previewing doesn't give you all the details. It keeps you from spending time on things you don't really want--or need--to read.

Skim--if it's short and simple. Skimming is a good way to get a general idea of light reading --like popular magazines or the sports and entertainment of your daily paper.

Here's how to skim.

●Get your eyes to move fast. Sweep them across each line.

●Pick up only a few key words in each line.

Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we'll get a similar idea of what it's all about.
