大家好，我是小夏，我来为大家解答以上问题。crude和rude的区别，crude很多人还不知道，现在让我们一起来看看吧！

1、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：

2、 Crude substances are in a natural or unrefined state, and have not yet been used in manufacturing processes.

3、

4、Raw materials or substances are in their natural state before being processed or used in manufacturing.

5、 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。

6、 另外，对raw还有如下解释：

7、 Raw food is food that is eaten uncooked, that has not yet been cooked, or that has not been cooked enough.

8、 因此有raw meet

9、 Raw data is facts or information that has not yet been sorted, analysed, or prepared for use.

10、 据此，应为raw fact.

11、 ……

12、

13、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。

本文到此讲解完毕了，希望对大家有帮助。
