There is a place on our earth where hot water and steam come up from under the ground．It is a large island in the Pacific Ocean．The island is North Island，in New Zealand．

The planet on which we live is a ball of very hot rock．It is a good thing for us that the outside shell is cold．If it were hot，no one could live here．What if our earth were only as big as an egg? Then the outside part would be as deep as the egg's shell．

The earth's shell has cracks in it in some places．In New Zealand this shell seems to have more cracks than in other places in the earth．There are spots where the ground is so hot that it burns the bottom of your shoes．In some places，hot water shoots into the air from time to time．At other points，you can see steam coming up from pools of hot water．

The people who live in these places make use of the heat coming from inside the earth．

Some of them cook in the hot pools They put food into a basket and place it in the water．Washing clothes is done in the same way．

Many people bring the hot water from below the earth into their homes．They do this by putting a pipe（管子）a hundred feet or more into the ground．In this way they get hot water and steam for cooking and washing，and for healing their homes．

For most of us，the heat under our feet is too far away to us．We must make our heat by burning coal，oil or gas．The people who get heat from inside the earth are lucky．It doesn’t take money to buy for coal，oil or gas．

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.
