Dear Li Ming，
This week in school, we discussed transportation. We learned about trains, planes, bicycles, cars and rockets.
The teacher asked us to think about the future of transportation. What types of transportation will people use a hundred years from now on? We had to think of an invention and present it to the class.
Today Danny gave his presentation. He put on an old backpack. He called it “Flying Donuts”. He got on a chair and jumped down. Then he said, “Did you see me? I flew!” We all laughed.
I would like to invent a clean car, but I don't know how. Do you have any ideas?

Dear Jenny,
That sounds like a fun project!
You're right about cars. They are very bad for our environment. People should walk or ride bicycles more often.That way, our air would be a lot cleaner. You can go far on a bike. Today I rode across the city.I pedalled for more than an hour!
Oops! I haven't answered your question yet. You can't pedal a car! Have you thought of a new fuel for cars?
In the future, cars will probably use water or sun energy to power them.
I hope your presentation goes well.
Li Ming
