今天我们来讲一下单选题题干和选项之间的逻辑关系。
我们通常会在题干和选项中发现一些逻辑关系,来帮助我们做一些排除或者是选项的一些选择。下面看例题:
Honey Bees in Australia 8-2-3
21 Where in Australia have Asian honey bees been found in the past?
A Queensland
B New South Wales
Cseveral states
22 A problem with Asian honey bees is that they
Aattack native bees.
Bcarry parasites.
Cdamage crops.
23 What point is made about Australian bees?
A Their honey varies in quality.
B Their size stops them from pollinating some flowers.
C They are sold to customers abroad.
24 Grant Freeman says that if Asian honey bees got into Australia,
A the country's economy would be affected.
Bthey could be used in the study of allergies.
C certain areas of agriculture would benefit.
解析:这篇文章基本上通篇都是在讲Asian honey bee,那我们先来看一下22题,由A、B、C三个选项可以看出来,它是在讲problem,非常消极的东西,也就是说Asian honey bee并不好。那我想让大家猜测一下,24题三个选项哪个是可以排除的。来看A选项说经济将会受到影响,而B选项说他们将会用在过敏学的研究中,而c选项讲的是一些地方的农业将会受益。那大家想一想,排除哪个选项呢?我们由此可以判断是排除C选项,为什么呢?因为人家通篇都在讲亚洲蜂不好的地方,那农业怎么会有收益呢?所以c选项是可以排除掉的。
