生活中的新事物越来越多，人们聪明的智商总能发明出一些好点子，这些发明都让我们的生活更加便捷，比如在1928年的美国，一个来自密歇根的人就发明了一个切面包片的机器，人们就被惊艳到，于是再也不用手切面包片了，那今天的习语跟面包片到底有啥关系？咱们听听Joy and Chris的对话吧！

C: Hi guys. I’m Chris.
 
J: And I’m Joy. Today we will be talking about the idiom: the best thing since sliced bread. It’s used when something is extremely good and interesting, usually describing a new product or a new invention. You can use it like this:

It’s the best thing since sliced bread. / It will be the best thing since sliced bread.

C: The literal meaning of this idiom is about the convenience of the invention of sliced bread. So a long time ago, people made bread by hand. Each time you wanted a sandwich or a piece of toast, you had to get out a knife and slice a piece of bread for yourself. And that all changed in 1928. Someone in America invented the world’s first bread-slicing machine. Then the companies began to use it to create prepackaged sliced bread, which was advertised as “the greatest forward step in the baking industry since bread was wrapped.” That advertising slogan led to the now-famous phrase “the best thing since sliced bread”. Now let’s use this idiom in a conversation:

 

 
J: Hey Josh. How’s your new car handling?
 
C: It’s pretty sweet. It’s got the auto park function. Man, it’s the best thing since sliced bread. I’ve never been good at parallel parking anyway.

 
 
J: So do you think our channel is the best thing since sliced bread? Haha just kidding.
 
C: And guys, if you enjoy our content, remember to share it with people you know! Talk to you next time! Bye!
