I've been working hard. I need some R-and-R.
R-and-R直译过来就是："R和R"其实，这个词原本是源于军队术语，它的全称是rest and recreation或者rest and relaxation，这个短语的正确意思是：“休息和放松”。因此，当美国人说"I've been working hard, I need some R-and-R."时，他/她要表达的意思就是:"I have been working hard. I need to relax myself."、"I have been working hard. I need to have a good rest."。
