Mouth is an important part of our body. When we eat food, talk with others, sing and smile, we use our mouth. Also, when learning English, we can find the word "mouth" in many sentences.
In everyday life, if someone says something bad about us, we can say "Do not bad mouth me" to talk back. Sometimes, if we say bad things that make others feel sad, we can say, "Sorry, I really put my foot in my mouth this time." We can also use "I am down in the mouth" to tell others our unhappiness. Sometimes when we talk with a friend and we have the same ideas with him, we can say, "You take the words right out of my mouth!" If some people have lots of money because of their rich families, in English, we can say, "They were born with a silver spoon in mouth." But a person who lives "from hand to mouth" is very poor and only has money to buy some cheapest things in need.
From the above examples, we can see that even the same English word can be used in different situations (情形)to tell others different feelings. English is a great language, isn't it?
