Look at these sentences:
I need some new summer clothes.
People need regular exercise to stay healthy.
I don't need to go home.
I needn't go home.
So what's the difference between 'I don't need to go home' and 'I needn't go home'?
Why do we think it sounds strange to say 'needn't'?
Feifei will explain how to use the word 'need' as a regular verb and as a modal in this programme.
