    When I was ten years old I went to the USA to visit some family friends. I noticed something funny about the way everyone spoke English.

    One moment! I remember very clearly was at the beginning of the holiday, when my friend asked me if I wanted to order “French fries”. I couldn't imagine what they were. She was amazed that I had never tried them and she ordered a portion for us to share. When the waiter brought us some chips, I asked her where the French fries were. She pointed at the plate of chips! Later that week she said she was going to buy some “chips” from the supermarket. She came out with a packet of crisps(薯片)! How come?

    During that holiday we were also offered “biscuits” with our lunch. This was a very strange idea to me, because in England biscuits are sweet. I later realized that “biscuits” in America are salty snacks. What we call “biscuits', they call “cookies”.

    I was also embarrassed when a stranger told me she liked my “pants”. I wondered how she could see them! My mum then told me that they call “pants” what we call “trousers”, the outer clothing that you wear on your legs instead of inside clothing!

    I was disgusted when I saw an “eggplant” pizza on the menu in a restaurant. But I was puzzled how eggs can grow on plants. My dad ordered this pizza and it was covered in aubergines(茄子). “They call aubergines 'eggplant' in America!” he told me.

    I think part of the excitement of learning a language is learning about the differences that exist in how it is spoken in different places.
