BILL:Do you know that people's life is getting better,more of them will buy cars?
When more people buy cars,cars will become cheaper.
LUCY:Why is that?
DU HUI:As more and more people have cars,
there will be fewer people wanting to buy cars,then cars will become cheaper.
LUCY:I don't agree with you two.People will always want cars.
When their car becomes old,they prefer to buy a new one rather than repair it.
