People use their mouths for many things. In the English language, there are many expressions using the word "mouth". But some of them are not so nice.

    Sometimes, people say something to a friend or a family member. Later they regret because it hurts that person's feelings. Or they tell the person something they didn't mean to tell. The speaker might say: "I really put my foot in my mouth this time."

    Sometimes when one person is speaking, he says the same thing that his friend is going to say. When this happens, the friend might say: "You took the words right out of my mouth!" Sometimes a person has a bad or sad experience with another person. He might say that experience "left a bad taste in my mouth." Or the person possibly has a very frightening(可怕的）experience, like having an angry dog running after him. He might say: "I had my heart in my mouth."

    Some people have lots of money because they were born into a very rich family. You might say the person "was born with a silver spoon (银勺) in his mouth". He is the opposite of a person living from "hand to mouth". This person is very poor and only has enough money for the most important things in life, like food.
