洪恩朗文3L看听学英语第三册 Lesson 35:Television Day: Mass-production

TV Commentary:Henry Ford built the world's first mass-production car in 1908.
Before 1908 cars were very expensive. Look at these two cars.
Which is the older? That's an easy question. Of course, the car
on the left is older than the one on the right. The car on the
left was expensive, difficult to drive, and it wasn't very
reliable. Only a few people could buy a car like this. The
car on the right is cheaper, lighter, faster and easier to drive.
Millions of people can buy a car like this. Why are mordern
cars so cheap and reliable? Because the makers build millions
of cars and make them all exactly the same. We call this
“mass-production”. Mass-produced things are usually cheap.
