Revision Write an email or a postcard to a friend telling him about the place where you are on holiday. The place I would like to visit would be Mars. I only know that it is the closest planet to the Earth, and it is the most similar to the Earth. Although Mars is the fourth closest planet to the sun, it is still much colder than the Earth. Like the satellites pictures showed that Mars has lots of craters, and scientists speculate that perhaps Mars used to be like the Earth billions of years ago. I think there is more to Mars than what the scientists believe. I believe there is life on Mars. Perhaps the definition of life on Mars is different from the Earth. It could be that the life there does not need oxygen, but other kinds of gases. I would imagine that life may not be active, because Mars has been hit by meteorites and the surface has been very much bombarded. So I presume the life that still exist would not be like life on Earth. I have no idea what the weather would be like, but I can presume it would be very cold, since Mars is much further from the sun than the Earth. As for its special features, I think if one stands on the surface of Mars, we can see the whole universe clearer than on the Earth. And perhaps it’s a million times more beautiful than the Earth. I hope one day we can have more exploration on Mars and solve the mystery.
