题目内容
7.There are at least two methods.Induction (归纳法) (as described by Darwin ),or deduction (演绎法)( as described by Einstein).Both methods can produce amazing result.But only when you know which"direction"to go.The steps are the same.They include:
Theory (理论)=Explaining how things work
Experiment=A way to test what's happening
Observation=Something you notice
Together,these are called the scientific method.
Should you start from the"bottom"by collecting information and facts to prove and seeing where chat leads you?That's induction.Charles Darwin (1809-1882 ) supported this method.He spent years observing the appearance and behavior of animals in different places.From this,he created his theory of natural selection:animal and plants can change because of their environment.
Or should you start from the by creating a theory and then seeing how it stands up to real life?That's deduction.Albert Einstein(1879-1955)was king here.He began with brave ideas.These theories often took years to prove by experiment.
A few of Einstein's ideas are still being examined.
In history,scientist have been solving problems using different methods.For example,while studying bacteria(细菌).Fleming found that something on bread could kill bacteria harmful to human health.This led him to discover a new medicine.Newton suggested that all objects attract each other.His idea was proved later.
So which way better?That depends.Some researchers do experiment,and only later consider where their results may lead them.That's induction.But deduction needs you to suggest a theory that may or may not be supported by the information and facts.The best scientists are always ready to change methods when necessary.

分析 短文主要介绍了两种方法归纳法和演绎法,以及它们的步骤,并举了一些例子.最后告诉我们也要使用适当的方法.
解答 答案:56.B 细节理解题.根据第三行句子The steps are the same.They include:这个步骤是相同的.它们包括:Theory (理论)=Explaining how things work.理论=解释它们是如何工作的.Experiment=A way to test what's happening.实验=一种测试正在发生的事情的方法.Observation=Something you notice.观察=你注意的东西.可知是三个步骤.故选B.
57.A 细节理解题.根据倒数第五段句子Should you start from the"bottom"by collecting information and facts to prove and seeing where chat leads you?可知从底层开始.故选A.
58.A 细节理解题.根据倒数第二段句子Fleming found that something on bread could kill bacteria harmful to human health.This led him to discover a new medicine.弗莱明发现,面包上的东西可以杀死对人体健康有害的细菌,这使他发现了一种新药.和最后一段句子Some researchers do experiment,and only later consider where their results may lead them.That's induction.一些研究人员做实验,然后才考虑,其结果可能会导致他们的感应.这是归纳法.可知是归纳法.故选A.
59.C 细节理解题.根据最后一段句子The best scientists are always ready to change methods when necessary.最好的科学家总是准备在必要时改变方法.可知告诉我们使用适当的方法.故选C.
60. A 主旨归纳题.根据这篇文章内容及其第一段句子There are at least two methods.Induction (归纳法) (as described by Darwin ),or deduction (演绎法)( as described by Einstein). 至少有两种方法.感应(归纳法)(如达尔文),或扣除(演绎法)(如爱因斯坦).可知主要说的是归纳法和演绎法.故选A.
