53、 weather has a great effect on how our minds and our bodies work. Maybethat is why there are so many expressions that use the word “cold”.For centuries, the bodys blood has been linked closely with the emotions. Peoplewho show no human emotions or feelings, for example, are said to be cold-blooded.T

54、hey may do brutal things to others, and not by accident.Cold can affect other parts of the body. The feet, for example. Heavy socks canwarm you feet, if your feet are really cold. But there is an expression-to get cold feet-that has nothing to do with cold or you feet.The expression means being afra

55、id to do something you had decided to do. Forexample, you agree to be president of an organization. But then you learn that all theother officers have resigned.

57、houlder 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.

58、cold fish could be cold-hearted. Now a cold-hearted person issomeone who has no sympathy. Several popular songs in recent years were aboutcold-hearted men or cold-hearted women who, without feeling, broke the hearts oftheir lovers.Out in the cold is an expression often heard. It means not getting something thateverybody else got. A person might say that everybody but him got a pay raise andthat he was left out in the cold. And it is not a pleasant place to be.45. If your friend promised to help you, but he didnt do that at all,.A. He was cold-hearted B. He was cold-blooded
