knowledge 用不定代词代替时用it还是they
▼优质解答
答案和解析
knowledge  是不可数名词,只能用表示单数的代词指代.人称代词用 it 指代,指示代词用 that指代,不定代词可以用 one 指代.
 
例如:

He has a wide knowledge of natural history and it has been obtained from his practice.她具有广博的自然史知识,这些知识都是通过他的实践获得的.【人称代词 it 指代知识本身】

He has a wider knowledge of natural history than that of common sense of life.他具有的自然史知识比生活常识更广博.【指示代词 that 指代与上文同类的知识】

He has a wide knowledge of natural history,one that has been obtained from his practice.

她具有广博的自然史知识,即通过实践取得的知识.【不定代词 one 是 knowledge 的同位语】
