(16) The socks that people wear on their feet are not very exciting but several interesting English expressions are made from them. One such expression is "pull up your socks". (14) It means "try to do better" or "improve your performance". Imagine a basketball team near the end of an important game. The players are lousy and they are so tired that even their socks look tired. The tops of their socks are falling down their shoes. The coach calls a time-out to talk to his team. "Take a deep breath," he tells them. "Get organized. If you pull up your socks, you can win the game." He is telling them they can win if they start playing better. A newspaper once reported that a political leader told the members of his party that they needed to pull up their socks and get back in the game. Another expression is "sock the money away". (15) It means "to save some money" instead of "spending it". A friend of mine tells you, for example, that she is socking some money away for a holiday trip. Word experts say the expression probably came from people hiding their savings in a sock instead of putting it into a bank. Questions 14 to 16 are based on the passage you have just heard.
