In our program, we explore(探究)the meaning of expressions in American English. We often take terms and examine them from "head to toe"------looking at each and every detail----making sure not to ignore(忽视) anything.

1.While listening to this program, you need to stay on your toes. We will give one example after another. So, you' ll need to listen closely or you might miss something. Staying or keeping on your toes not only means to pay close attention. 2. This expression comes from the fact you are ready to jump off a ball into action. The phrase " keeping on your toes" is different from "tiptoeing around". When you are on your toes, you are ready to take action. 3. If you are not balanced, you are about to fall down. As we can see, "tiptoeing around" has something with being not direct. So, in American English, "to tiptoe around something" means to talk out something in an indirect (不直接的) way.

4. If we have some problems or do something wrong in our lives, our parents or teachers advise us not to avoid them. Instead, we should face them directly and bravely. 5.

And that' s “Words and Their Stories” for this week. Thanks for listening.
