情态动词could的用法
【教材原句】

情态动词could 构成的问句用于向对方委婉地提出请求或征求对方的许可，语气比can委婉，但不
表示过去，答语没有固定形式，符合语境即可。
1.委婉地请求他人可用“Could you do...?”“Could you please do...?”提问，若对方同意请求可以说
“Certainly./Of
course./With pleasure./No problem./Yes./Sure.”；若对方不同意请求可以说“No,I can't./Sorry,I can't.”。
2. 委婉地请求别人允许自己做某事可用“CouldI do...?”提问.
若对方同意，可以说“Yes,you can./Certainly./Sure.”；若对方不同意，可以说“No,you can't./Sorry,I'm afraid
you
can't.”。注意回答中用can,而不是could.
