《牛津词典》

supplement

to add something to something in order to improve it or make it more complete

scholarship

1 [countable] an amount of money given to somebody by an organization to help pay for their education

2 [uncountable] the serious study of an academic subject and the knowledge and methods involved

根据词典对supplement的释义，supplement表示给宾语补充内容，使之改进或更加完善。因此，我赞同黎老师的解答，即在法律事务所兼职的目的是补充学识（to improve it)。

如果将scholarship理解为奖学金，则与supplement的语义不符，因为兼职并不能improve the scholarship(奖学金）。

原句：To supplement his scholarship, he has a part-time job in a law firm downtown.  

找到的翻译：除了奖学金以外，为了增加收入，他在市区的一加律师事务所兼职。

疑问：“To supplement his scholarship”是指“为了补充他的奖学金”，感觉不通，奖学金怎么补充？这里supplement怎么理解？

【答】这里的 scholarship 是一个不可数名词，意思是“学问，学识，学术研究”，不是“奖学金”。To supplement his scholarship 是动词不定式短语，作目的状语，即用来表示谓语动词动作发生的目的。句意：为了增加学识，他在市区的一家律师事务所兼职。

解答入下

以上为“动词不定式”作目地状语，即用来表示谓语动词动作发生的目地。

To supplement his scholarship, he has a part-time job in a law firm downtown. He has a part-time job in a law firm downtown to his supplemencholarship.
