chest 胸,胸膛
Put the idiom on one's chest into Chinese,and you will see for the word chest,the Chinese equivalent is a word meaning “heart”. If something is on your chest, you had better get it off your chest.
Chest also means a large box. For instance, a chest of drawers is a large box with drawers for clothes. But the community chest isl not a box. It is the money raised by the community for charitable purposes.
把on one's chest(心中有事,闷闷不乐)的习语译为中文,你就会看出chest一词相当于中文的“心”字。如果你心中有事,你最好把心事倾吐出来(get it off your chest)。
chest还可以指大箱子、大柜子呢,例如a chest of drawer,就是放衣服的五斗柜。但community chest却不是箱子或柜子,它是用于慈善事业的社区基金。
