老师：Hello, boys and girls. Nice to meet you. I'm Miss Liu from Hongguan Middle School. Welcome to this lesson. Today we are going to learn Unit 4, Life on Mars, revision. Boys, girls, we are living in a vast universe. The earth is our home. Mars is the nearest planet as Earth's neighbor. Mars has a similar environment. For years, humans are exploring the Red Planet and hope to live on it one day. China just launched a major Mars mission called Tianwen 1. It is China's first solo mission to Mars.
老师：And volunteers of training camp wanted. Do you want to try? Let's go. In this unit, we know lots of items for traveling in space. Look at hobo and Eddie. What items did Eddie take? Are they necessary or not? They take helmets and food. They are necessary because Eddie cannot breathe without helmet and they cannot live without food. What about the ours? What items do we need? We may need I tank, tent, dried food, space helmet, special boots, computer power pack, sleeping bag and space a suit. What other items might we use? Read this passage and fill in the blanks.
老师：Welcome to the Mars shuttle. You will find a few unusual things in the back under your seat. You can use them during our trip. After we arrive, please take out your bag now and learn to use the items in it. Your air tank will allow you to breathe outside on Mars. See the hotness on the tank? You use it to carry the tank on your back. The tube coming out of the tank will carry air to your helmet. Inside the helmet you can find a microphone. If you go out of your house on Mars, you can talk to your family members with it. And these special space boots will allow you to walk a month. You also have a pair of special sunglasses for the trip. This will protect your eyes from the strong sunlight. Use your space timer instead of a normal watch. Time passes differently on Mars and you don't want to miss the shuttle. Back in the bag, there are some vitamin pills for you if you feel sick on the trip. Lastly, remember to wear this temperature controlled suit. It will help your body adjust to the temperature on Mars. Boys, girls, what items can you find on the mouse shuttle? Can you circle them? Air tank, microphone, space boots, sunglasses, space timer, vitamin pills, suit. Very good.
老师：Of all the things, which three are the most important when you live on Mars? Why? In my eyes, special suit, boots and power pack are the most important items. Because I can breathe with special suit, walk with special boots and work with a power pack. And I believe you have your own ideas, too. In the reading part, we know Mars. Now fill in the blanks.
老师：The earth is becoming more and more crowded and polluted because of the rapid increase in population. It is hoped that people could start all over again on Mars
