Cách sử dụng
"If need be" is an expression used to say that something will happen only if it is necessary or required. It can be used when you are talking about a situation where there may be a possibility that something will need to be done or used, but it's not certain. It's often used to indicate a backup plan if the original plan doesn't work out. For example, "We will take the bus to the station, but if need be, we can call a taxi."
