“to have knowledge of”是一个常用的英语短语,核心含义是“了解;知道;对……有(某种程度的)认识/知识储备”,强调主体对某一事物、领域或情况具备一定的信息或认知。
表示“拥有关于某事物的知识”,可通俗理解为“知道/了解某事”,但比普通的“know about”更强调系统性或一定深度的认知(而非仅仅“听说过”)。
该短语的核心结构是:
其中:
修饰词:可加形容词(如`some/basic/good/thorough`等)表示认知的程度;
宾语:需是名词、代词或名词性短语(因为“of”是介词,后接名词性成分)。
以下通过不同场景的例子说明其用法:
She has a good knowledge of French literature.(她对法国文学有很好的了解。)
Do you have any knowledge of computer programming?(你懂一点计算机编程吗?)
As a teacher, you should have basic knowledge of child psychology.(作为教师,你应该具备基本的儿童心理学知识。)
The police have knowledge of the suspect’s escape plan.(警方掌握了嫌疑人的逃跑计划。)
I don’t have any knowledge of that accident—can you tell me more?(我对那起事故一无所知——你能详细说吗?)
We were surprised to learn that he had knowledge of our secret project.(我们惊讶地发现他知道我们的秘密项目。)
Researchers must have thorough knowledge of relevant studies before starting a new project.(研究者在启动新项目前必须全面了解相关研究。)
This job requires candidates to have advanced knowledge of data analysis.(这份工作要求候选人具备高级数据分析知识。)
have a knowledge of:更常见(加不定冠词`a`),强调“某一方面的知识”,可与程度词搭配(如`a good/thorough knowledge of`);
have knowledge of:更侧重“存在某种知识”,可加`some/any/no`等限定词(如`have some knowledge of`“有一些了解”,`have no knowledge of`“一无所知”);
know about:更口语化,强调“听说过/知道基本情况”,不如“have knowledge of”正式或强调深度;
be aware of:侧重“意识到/注意到”,而非“具备知识”(如`I’m aware of the problem, but I don’t have knowledge of how to fix it.`“我意识到问题,但不知道怎么解决”)。
不可说“have knowledge to do sth”,需用“have knowledge of how to do sth”(知道如何做某事):
✖️ I have knowledge to repair a bike.
✔️ I have knowledge of how to repair a bike.(我知道怎么修自行车。)
否定形式常用“don’t have any knowledge of”或“have no knowledge of”(一无所知):
He has no knowledge of what happened last night.(他完全不知道昨晚发生了什么。)
“to have knowledge of”是表达“对某事物有认知/知识”的正式短语,适用于口语和书面语,核心是强调“拥有某方面的信息或知识储备”,常与程度词搭配以说明认知深度。
