在超市用英语怎么说

在超市用英语可以说 "at the supermarket"。来源方面，超市这个词是由英文 super（意为超级的）和 market（市场）两个词组合而来，所以就成了超市这个词。
例句：
I need to go to the supermarket to buy some groceries.
There's a sale at the supermarket this weekend. You should check it out.
Do you want to come with me to the supermarket? I need to pick up a few things.
