Question

I know a little about Chinese history.(改为一般疑问句)

Answer 1

Do you know a little about Chinese history?
方法：陈述句改成一般疑问句，首先要看句子的动词，假如动词为实义动词，则要借助助动词，并将助动词提到句首；例如，该句子中的Know就是实义动词，而且主语是第一人称，所以就借助Do.
若句子中有情态动词，例如will，would，can等，则只需将情态动词直接提到句首即可。例如：I will visit my friend tomorrow. 改成一般疑问句： Will you visit your friend tomorrow?

PS：学英语是一定要懂语法的，建议你早日掌握它，那样你未来的英语求学之路会好走些。
