—Would you give me a hand，Ricky？

—Sure!What do you want me to do？

——里奇，你能不能帮我一个忙？

——没问题!你要我帮你做什么？

解析：Sure．也可以说成Certainly．，表示欣然同意或赞成。英语中表示完全同意对方的看法或意见，可以用Certainly．／Sure．／Of course．／Good idea．／Great！如：—Shall we go for a walk？— Good idea．；如果表示一般同意，可以用Yes，please．／That's true．／All right．／OK．／I agree with you．；若只表示附和，常用I think so．/I'm afraid so．；表示不同意常用No，I don't think so．／I'm afraid not．/I really can't agree with you．。
