范例：
Is there life on Mars? We don't know.Can we land on Mars? It all depends on the development of science and technology.Man has known a little about Mars.There is almost no oxygen on Mars.It might be about 50 degrees above zero at noon and 100 degrees below zero at night, which prevents us from living there.Now that Mars are quite different from our earth, if we are to go to Mars one day, we should have to take along our own oxygen, food and clothing.But it is certain that with the development of science man will land on Mars in time.
