Can/Culd表请求/允许的用法
情态动词can/culd构成的句型可用于向对方委婉地提出请求或征求对方的许可。它们本身不能作谓语，只能和动词原形一起构成谓语。
1.用于委婉地请求别人做某事
—Culd yu srt these things int bxes? 你能把这些东西分类装进箱子吗？—Yes, sure.好的，当然可以。—Can yu clean the bathrm? 你能打扫浴室吗？—Srry, I can’t. I have t d my hmewrk nw. 抱歉，我不能。我现在必须做家庭作业。
2.用于委婉地请求别人允许自己做某事
— Culd I g t the mvies? 我可以去看电影吗？— Yes, yu can. 是的，你可以。— Can I pen the dr? 我可以开门吗？— I’m afraid yu can’t. It’s t cld! 恐怕不行。天太冷了！
无论是“Culd yu (please) ... ?”还是“Culd I ” ，问句中的 culd 都可用 can 来代替，但是 culd 更委婉。且答语中一般都避免使用 culd 来回答。
culd 的其他用法如下：
(1)culd 为 can 的过去式，表示能力。 He culd ride a bike at the age f five. 他五岁时就会骑自行车了。
(2)表示可能性，指对过去、现在或将来的某种可能的推测。 The bk culd be Lily’s because she likes reading bks. 那本书可能是莉莉的，因为她喜欢看书。(3)表示建议。 Yu culd g there by bus. 你可以乘公共汽车去那儿。
