I want to be a scientist in the future.

If I become a scientist， I will invent（發(fā)明）a machine to let the air and the water be fresh and clean.

If I become a scientist， I will make a submarine to go into the sea and get to know how deep the ocean is and where the Atlantic is.

If I become a scientist， I will invent a kind of food. If you eat it， you shouldn’t take other food. And I will give this food to poor people.

If I become a scientist， I will invent more things good to the world.
