Welcome to English in a Minute!

A mile is a unit of measurement equal to about 1.6 kilometers.

And a minute is equal to 60 seconds.

a mile a minute 飞快

Anna: I've been thinking about your birthday...

Jonathan: Uh-oh. What have you been thinking, Anna?

Anna: A party. A big party. With 10 kinds of pizza. And balloons. Maybe a clown, and definitely chickens all over...

Jonathan: Slow down, Anna. Your mind's going a mile a minute! How about we start this party idea with something small, like a cake.

The expression "a mile a minute" means that something happens very quickly.

We started using the phrase in the mid-1900s when 60 miles per hour,

or a mile a minute, was considered a very fast speed.

And that's English in a Minute.
