People use their mouths for many things. They eat, talk, shout and sing. They smile and they kiss. In the English language, there are many expressions using the word mouth. But some of them are not so nice.
嘴巴的用途很多，人们用嘴吃饭、谈话、呐喊、唱歌、微笑和亲吻。在英语中，有很多包含嘴这个单词的短语。但其中一些可不太友好。
For example, if you say bad things about a person, the person might protest and say "Do not bad mouth me."
比如，如果你说某人不好的方面，这个人可能会抗议，说“不要说我坏话”

The speaker might say: "I really put my foot in my mouth this time." If this should happen, the speaker might feel down in the mouth. In other words, he might feel sad for saying the wrong thing.
这个发言者可能会说：“这次我真的说错话了”。如果发生这种情况，这个发言者可能会感到沮丧。换句话说，他可能为说错话觉得悲伤。
Another situation is when someone falsely claims another person said something. The other person might protest: "I did not say that. Do not put words in my mouth."
另一种情况是，当有人谎称别人说了什么时。别人可能会抗议：“我没有这样说。不要把这个话强加于我。”
