Nowadays many new and useful inventions have come into use. If I were a scientist, I would have my own invention―a magic door, a door that can take me to every part of the world.

Since our life is getting busier and busier,my magic door is really needed. The population of the world is rising day by day,and the number of cars is getting larger. So traffic jam becomes a big problem for people in both poor and developed countries. Mo?reover, by using a large number of cars,people have to face another problem—-the pollution of the air. All those reasons lead to the need for such an invention like a magic door. It can take the place of ways of transportation.

Magic doors have many advantages(好处).First,you can go wherever you want in a minute. Just open the door and go through it,you can stand in another place. Two parts of the door are two parts of the world. Thus,magic doors can meet the need for dis?covering new places for people. Second, magic doors sometimes can even make people safe. Magic doors can be used in everyday life. If you dropped into a river by accident?for example,people would go there at once to help you get out of danger by using magic doors.

All in all,people can benefit (得益)a lot from magic doors. If magic doors were invented and came into use widely,not just imagination,there would be a big change in our life!
