[00:02.97]Speaking: [00:04.41]Exercise 1 Listen to a class presentation [00:08.22]about Mars and complete the notes. [00:11.45]Right, today I'm going to talk abut Mars, [00:14.30]the "red planet". [00:16.05]Mars, named after the Roman god of war, [00:18.53]is called the Red Planet because, [00:20.38]as you can see in this photo, [00:22.10]it actually looks red. [00:23.68]But Mars is not only an extremely [00:25.58]beautiful planet.For a long time this question [00:28.71]has interested us-"Is there life on Mars?" [00:32.75]Well, first I'd like to talk [00:34.54]about the planet itself. [00:36.26]In many ways, Mars is our next-door neighbour. [00:40.02]Venus is actually nearer [00:41.57]but has a very tough environment, [00:43.57]covered in clouds of poisonous gas [00:46.20]and with temperatures of up to 500C. [00:50.67]Mars is cooler, has an atmosphere made up [00:53.84]of carbon dioxide and its gravity [00:56.64]is a third of that on Earth. [00:58.62]Mars has two moons,and its surface is covered [01:02.38]with valleys and huge volcanoes. [01:04.89]The valleys were probably made [01:06.47]in the past by water on the planet. [01:07.91]
