求问狒狒逻辑 97

A scientific theory is a good theory if it satisfies two requirements:it must accurately describe a large class of observations in terms of a model that is simple enough to contain only a few elements,and it must make definite preictions about the results of future observations .for example ,aristotle's cosmological theory,which claimed that everything was made out of four elements-earth ,air,fire,and water-satisfied the fist requirement,but it did mot make any definite predictions.so it is not a good theory.

if all the statements in the passage are true ,eash of the following must also be true EXCEPT:

A )Prediction about the results of future observations must be made by any good scientific theory

B) Observation of physical phenomena was not a major concern in Aristotle's cosmological theory.


C)  Elements that is simple enough to meet the simplicity criterion of a good theory can be the basis of a scientific model

D) A scientific model that contains many elements is not a good theory.


E) Aristotle's cosmological theory described a large class of observations in terms of only four elements .
答案是B 我同意 但是求问A为什么对呢？ 原文说， it must make definite preictions about the results of future observations 但是反过来是不能证明的啊？？？？

我也感觉A有问题啊。。。对未来现象的预测并不是必须由好的科学理论的出来啊，我瞎预测也可以啊！

我想说所有的理论应该都可以做出prediction呀

我也疑惑 ~  

你说A选项里头的句子到底是该翻译成prediction一定是由good theory得出的还是翻译成prediction必须是由good theory得出的

就好比，我爱着你，你被我爱着

xw909

a推出b，b可以被a推出，是一样的，不是b可能被a推出，是一定

kiddyft

LS 从语法上看貌似是一样的，只是主动变被动，但是意思我始终没理解到哎

xw909 你的意思是说 a推出b 则b可能被a推出吧？ 但是文中是must be made by ，按你的意思的话不应该是can be made by才对么？那个选项中文到底什么意思啊？我觉得应该是我理解错了...

好吧 我是大姐...而且头脑转不过来的那种...

原文是  it must make definite predictions about the results of future observations和答案a的Prediction about the results of future observations must be made by any good scientific theory从语法上说是完全一样的。对的

richardyam15

从语法的角度看，这两句话意思是完全一样的，所以是对的。
