Sample ；
In my opinion, the ball-point pen is one of the most useful inventions during the 20th century. It was invented by an American tanner named John Loud in 1888. It was used for writing faster. And it really helps us write faster than pen，so it makes our life easier. And we can buy it at a low price. Students like it very much. But sometimes the ball-point pens leak and need refilling.
Ball-point pens are becoming; smaller and lighter. They are widely used in our lives，they are popular with students，teachers and office workers.
