Today we will talk about expressions that use vegetables and fruits. For example, a cucumber is a long, green vegetable that people often eat in salads. You might say a person is as cool as a cucumber(黄瓜) if he never seems to worry about anything and stays calm in a stressful situation.
If two people are very similar, you might say they are like two peas in a pod. There are several expressions about beans. If someone is very energetic, you might say she is full of beans. If you say something does not amount to a hill of beans, you mean it is of little importance. I might say you don't know beans about a subject if you do not know anything at all about it. But if you spill the beans, you tell something that was supposed to be a secret.
Potatoes are a popular food in many areas. But something is considered small potatoes if it is not important. You probably would not want to hold a hot potato in your bare hands. This also means a problem or issue that no one wants to deal with. Someone might call you a couch potato if you sit and watch television all day and get little or no physical exercise.
Farmers have to separate the valuable parts of their crops from the waste. So separating the wheat from the chaff means keeping what is valuable and rejecting(去除) what is worthless.
