Watch and learn 3 ways to use ‘pick up’

Hi, this is Kee from BBC Learning English.
Today I’m going to tell you three different
ways of using the phrasal verb ‘pick up’.
First, we use ‘pick up’ to describe learning something.
So, for example, I can say:
Children pick up languages very quickly.
And so can you at BBC Learning English!
Second, we use ‘pick up’ informally
to describe buying something.
For example:
I often pick up some milk on my way home.
Third, we use ‘pick up’ to describe getting an illness.
I think I picked up a cold.
So, we can pick up languages,
pick up some milk and pick up a cold.
