Cold weather has a great effect on how our minds and our bodies work. Maybe that is why there are so many expressions that use the word cold.
For centuries, the body’s blood has been linked closely with the emotions. People who show no human emotions or feelings, for example, are said to be cold-blooded. Cold-blooded people act in cruel ways. They may do brutal things to others, and not by accident.
For example, a newspaper says the police are searching for a cold-blooded killer. The killer murdered someone, not in self-defense, or because he was reacting to anger or fear. He seemed to kill for no reason, and with no emotion, as if taking someone’s life meant nothing.
Cold can affect other parts of the body. The feet, for example. Heavy socks can warm your feet if your feet are really cold. But there is an expression — to get cold feet — that has nothing to do with cold or your feet.
寒冷会影响身体的其他部位。比如脚。如果你的脚真的很冷，厚袜子可以温暖你的脚。但是有一个表达——get cold feet——和寒冷或者你的脚没有关系。
The expression means being afraid to do something you had decided to do. For example, you agree to be president of an organization. But then you learn that all the other officers have resigned. All the work of the organization will be your responsibility. You are likely to get cold feet about being president when you understand the situation.
Cold can also affect your shoulder. You give someone the cold shoulder when you refuse to speak to them. You treat them in a distant, cold way. The expression probably comes from the physical act of turning your back toward someone, instead of speaking to him face-to-face. You may give a cold shoulder to a friend who has not kept a promise he made to you. Or, to someone who has lied about you to others.
A cold fish is not a fish. It is a person. But it is a person who is unfriendly, unemotional, and shows no love or warmth. A cold fish does not offer much of himself to anyone.
Someone who is a cold fish could be cold-hearted. A cold-hearted person is someone who has no sympathy. Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feeling, broke the hearts of their lovers.
Out in the cold is an expression often heard. It means not getting something that everybody else got. A person might say that everybody but him got a pay raise, that he was left out in the cold. And it is not a pleasant place to be.
Out in the cold是一个经常听到的表达。它意味着不能得到其他人都得到的东西。一个人可能会说，除了他以外，每个人都加薪了，他被冷落了。这不是一个令人愉快的地方。
