Example
A: What do you know about the natural features of a desert ?
B: Oh, yes. As we known, desert is a hot, dry and sandy place. It’s very hot during the day but it’s very cold at night.
A:
Although the rainfall is very little, the sunshine is too much.
B: As a result, very few trees and animals exist in a desert. Only cactus and camel exist in a desert for long.
A: And very few people can live there except for in Oases.
B: In sum, life in a desert is extremely severe because of lack of water and food.
Task 3: Work in groups. You are going on an expedition across a desert with some of your friends. Discuss and choose the five most important things you should bring along with you. Explain your choice.
a knife
a box of match
water
a gun
a car
a mosquito net
a horse
a camel
a cell phone
food
a blanket
a walkman
Example
A: What should we bring with us when we across a desert?
B: First of all, we need to have camels. We can’t use a car or any means of transportations because it’s difficult to move in the desert and we can’t store enough petrol for a expedition.
C: In my opinion, we’ll bring a lot of food and water. They can help us to survive in the desert if we get lost.
D: To me we should bring knives to cut food or fruits.
A: And a box of matches is very necessary for us to make a fire at night.
B: Well, I think these things are enough for our expedition.
