crude和raw的区别?
crude和raw到底有什么区别呀?我指的是在“原始的,未经加工的”这层意思上有什么区别.raw还有阴冷的意思就不用说了.
似乎经常搭配的是：crude oil和raw data, raw material, raw meat
可是好像也看过raw oil的搭配.另外,到底是raw fact还是crude fact啊?还是都行?

在“原始的,未经加工的”这层意思上,crude与raw是近义词,试比较两者的英文解释：
Crude substances are in a natural or unrefined state,and have not yet been used in manufacturing processes.
Raw materials or substances are in their natural state before being processed or used in manufacturing.
可见二都几乎没有什么区别,通常都用于作定语,而crude oil则比较常用.
另外,对raw还有如下解释：
Raw food is food that is eaten uncooked,that has not yet been cooked,or that has not been cooked enough.
因此有raw meet
Raw data is facts or information that has not yet been sorted,analysed,or prepared for use.
据此,应为raw fact.
……
总之,raw的用法多于crude,具体建议参考Collins COBUILD Dictionary,内有非常明了的用法解释.

a)rude b)crude c)raw d)coarse的区别 crude和raw在表示“天然的”的意思时,是同义词吗? crude和rude有什么区别? primitive man,crude oil,raw material这几个搭配都对吗? cough coarse crude做“粗糙”时,有什么区别呢?不想要拷贝的, rough ,coarse,crude有什么区别?最好举几个常见的搭配, rude和crude在表示“粗鲁的,粗俗的”时候有什么不同? 求Crude Oil Processing和Oil and gas processing的PDF原文相机的RAW 是什么意思呀? 英语raw的意思是什么 Raw deal的中文意思是? raw material is what we are badly in need of .和raw material
