All right 好的(表示同意) e.g. -Would you pass that bottle to me?-All right! That's all right 没事的,还行(表示原谅) e.g. -I'm sorry that I broke your glass.-That's all right That's right 是的,没错(表示判断) e.g. -Did you stay with the Smiths last night-That's right That's ok/It's ok(是没关系)常常用于回答别人的道歉,如别人在某件事情上向你道歉:I'm sorry~!你回答:That's ok!
all right 可以作口语,没什么特别意思,意为好的 that's all right 用来回答sorry,意为没关系 that's ok ,it's ok 意为没事,好的,可以,和all right可以通用,没什么大分别,都是口语用语 that's right 对的,正确的,用来回答判断正误的时候
