Speaking:
Exercise 1 Listen to a class presentation about Mars and complete the notes.

Right, today I'm going to talk abut Mars,the "red planet". Mars, named after the Roman god of war, is called the Red Planet because, as you can see in this photo,it actually looks red. But Mars is not only an extremely beautiful planet.For a long time this question has interested us-"Is there life on Mars?" Well, first I'd like to talk about the planet itself.
In many ways, Mars is our next-door neighbour. Venus is actually nearer but has a very tough environment, covered in clouds of poisonous gas and with temperatures of up to 500C. Mars is cooler, has an atmosphere made up of carbon dioxide and its gravity is a third of that on Earth. Mars has two moons,and its surface is covered with valleys and huge volcanoes. The valleys were probably made in the past by water on the planet.
