How is life in the desert different from other places where people live? Life in the desert is much harder. First of all, it is hard to find water, and people usually move from place to place. What’s more, the weather in the desert is very dry and hot. In other places, people usually have stable homes and enough water. The weather is better than that in the desert. 2. Would you like to visit the Sahara Desert or even live there for a while? Why or Why not? I would like to visit the Sahara Desert. Because I want to see its amazing landscapes, like sand seas and the rocky ground./I don’t want to live there. Because it’s too hot and difficult to find water. 3. What do you think will happen if the Sahara keeps getting bigger? What should we do about it? If the Sahara keeps getting bigger, I think more land will dry up, and people and animals there may lose their homes. We should take effective measures, such as reducing pollution, planting more trees, and saving water.（答案不唯一，仅供参考） 根据文章内容，从方框中选单词并用其适当形式完成短文 The Sahara Desert is a famous natural wonder.
