It seems impossible today, but by the year 2314, we will be able to live on Venus. Here is a guide to what I think life on Venus will be like.

　 First of all, the temperature on Venus is too high to support life. However, scientists will try to find a way to build spacesuits and space houses to keep us cool and safe from the heat. It will use the power of the sun. Everything will be very expensive on Venus because they are from Earth. On Venus, the food will be very dry and tasteless. If you have a lot of money, you can buy the food that comes from Earth every week.

　 The best thing about life on Venus is the transport. Because there are fewer people on Venus than on Earth, there is more space and fewer cars on the road. Also, high-speed electronic trains connect people’s homes to everywhere else. You can go to school, go shopping, go to work fast, safely and conveniently, just within minutes.

C：

Even if you are a good high jumper, you can jump only about seven feet off the ground. You cannot jump any higher because the earth pulls you hard. The pull of the earth is called gravity. You can easily find out the pull of the earth. If you weigh yourself, you will know how much gravity is pulling you.Since there is gravity, water runs down hills. When you throw a ball into the air, it falls back down. Because of gravity, you do not fall off the earth as it whirls(旋转) around.

Then, can we get away from the earth and go far away into the space? Now you can do it, because the spaceships have been invented. The spaceship will go so fast that it can escape the earth gravity and carry you into space.
