Brad: 大家好，我是Brad.

　　Nick: 在生活中，大家有时候做事就做到无用功，就是说做了跟没做一样，浪费时间。或者说话，有时候说了跟没说一样。举个例子，你想去打球，但是你的朋友在做作业，而且他不爱打球，你叫他打球，一般都是白费口舌对吧，说了没有用。或者说一个人很固执，也不爱学习，很多人都劝过了，但他从来不听。你呢，还跑去劝，可能这也是白费口舌，对吧这么多人都劝不听，你劝有什么用呢？那在这里，白费口舌用美语怎么说？

　　Nick: hey Brad. I wanna write a letter to Scarlet Johansson's agent.

　　Brad: For what? Are you serious?

　　Nick: Yeah you saw that video on? A high school kid just recorded a video, imitating La LaLand and sent it to Emma stone, asking her to attend his graduation prom!

　　Brad: And you know he failed, right? Emma turned him down. To be honest, this is kinda silly.

　　Nick: Well. You never know. I'd like to give it a shot!

　　Brad: He was beating the dead horse, man.

　　Nick: Um.. I think you are right. I'll just give it up.

　　beat the deadhorse就是白费口舌的意思，但是呢要注意，这个词有更宽的用法。它不仅仅是说说话的时候，也可以用在做事情，do something that is a waste of time。在我举的例子里，我是想说，一个人录视频邀请emma stone，然后他失败了。我也想做一个视频，邀请scarlet，然后Brad说这件事情就是无用功，不会有效果的，就是beat the dead horse."打死了的马"是没有用的。 So this is pretty much it for this time, I'll see you guys next time. Bye
