我可以用could代替can ?

是的, could在这里can用CAN代替。将其更改为can不会更改文本的含义。在某种程度上, can听起来比更自然的could 。但是,它们不一定是可互换的,并且有时could并且can是不可互换的。 can表示can做某事或被允许做某事,但是could用来描述做某事的可能性或做某事的能力。这里有一个例子could和can不能互换。示例: When I was a child, I could do cartwheels! (我小的时候可以做横向投影!)示例: I can knit. (我可以编织。)接下来,让我们看看其中一个例子could和can可以更换。示例: Can you tell me how to get to Times Square? ( Could you tell me how to get to Times Square?能Could you tell me how to get to Times Square? )示例: Could you tell me how to get to Times Square? (您能告诉我如何到达时代广场吗?)
