Writing   (Page 120)
Imagine you are journeying through a desert. Write a couple of paragraphs describing what you see and hear.
Ans. A desert is not a place worth living. It is a nightmare to journey through the Thar Desert. From my personal experience I know how hot the deserts are. I saw end­less expanse of sand and sand dunes. Only here and there I saw a few thorny bushes. There are very few birds. The camel is a common sight. There are only small villages around oases. Life is very hard there. Water is scarce, so is green­ery.
We hear the blowing of hot winds and the howling of sand storms. We can hear the calling of mongooses and the howling of jackals. Now and then we can hear the tinkling of bells round the neck of camels.

sandy with hardly any vegetation or villages. There is neither water nor greenery. Still some animals are found there. For example, gerbils, beetles, snakes, mongooses and camels.

A camel can drink upto 30 gallons of water in just ten minutes. It eats plants. Its humps store fat-food.
