Reading "Let's Go To My House"

Read the text below and answer the questions after it. All the questions have got only one correct answer.

The very first kind of house was a cave. It had walls that kept out strong winds and wild animals. It had a ceiling that kept out the rain. It had a floor on which to sit or curl up and sleep.

In time people learned to build houses. They used different materials they had. In dry places, the houses were made of mud and clay Where there was plenty of wood, people built houses of logs. On grassy places, they built houses of grass. They learned to use mud and clay to stick stones together and they made great towers of stones.

Can there be an igloo in Africa or is that a silly idea? You see, «igloo» is the Eskimo word for house — any kind of house. An igloo can be made of wood, stone, mud, skins, grass or snow. So you could have an igloo in Africa. But not a snow igloo.

In Africa, where it is hot and dry, mud is a good building material. And people in Africa make huts with mud walls. Thick walls help to keep the houses cool.

Today many people still live in houses made of mud, or dry grass, or logs. Others live in houses made of stone and bricks.

No matter where we live, all our houses have walls, ceilings and floors to protect us from rain, snow and wind.
