典例剖析
The ballpoint pen is widely used all over the world now. Let me tell you something about it.
It was invented by an American named John Loud in 1888 and it really helped people write faster and made their work easier. Sometimes the ball-point pen leaked and it needed refilling.
But the ball-point pen has changed a lot. The price is usually low. The ball-point pen is becoming smaller and lighter. It is really useful and convenient in our life.
I think it is one of the greatest inventions in history.
