一、详细释义：

作证，证明 [I,T]


例句：

例句：

二、词义辨析：


assert,affirm,allege,maintain,testify,claim

这些动词均含有“断言，声称”之意。 assert主观意味强，指自认为某事就是如此，而不管事实如何。 affirm侧重在作出断言时表现出的坚定与不可动摇的态度。 allege多指无真凭实据，不提供证据的断言或宣称。 maintain与assert近义，但前者指坚决维护某种主张或观点。 testify多指在法庭作证，庄严地宣称自己所说属实。 claim可与assert换用，但语气弱一些，侧重指行为自己的权利提出要求他人承认。


三、参考例句：

他的朋友们将为他作证。
