Animals(动物) need it too.Most of the salt in our country comes from the sea(大海). People dig(挖) great pools and let sea water in. When the sun dries up (晒干) the water, people can get salt from the ground. The salt is white, clean and beautiful.There are a lot of salt wells(井) in Sichuan. A salt well is much like a water well. People bring the well water up to the ground and then dry it in big jars over fire. In this way, they get salt.We can also get salt mines(矿). Some years ago people in Jiangxi found(发现) a big salt mine and soon opened it. People there no longer (不再) need salt from other places(地方).In the northwest(西北) of our country, there are many salt lakes(盐湖). Some of these lakes are very big.

Sea WaterCWhen you watch TV and play video games, you make environment worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases (温室气体). This means that every time you use electricity you help make global environment worse!Cars are also making global warming worse, and send lots of greenhouse gases into the air. Global environment may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help! Why not try one of these top ideas?▲ Try to use less electricity. Turn off lights, your television, and your computer when you've stopped using them.▲ Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air.▲ Don't throw away your rubbish, but try to recycle it. If rubbish is not recycled, it is put on the ground. There it rots(腐烂) and makes a greenhouses gas called methane(甲烷). So try to recycle cans, bottles, plastic bags and newspapers.They will make you feel great! And they will help the earth.63.

As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles.In the Second World War, some people didn't use gas made from petroleum(石油) in their cars. They made gas from wood and plants instead. The car didn't go fast, but they ran, so this was better than nothing. However, in the future, we can't cut down all our trees to make gas; we need our trees for other things, too.Besides different types of gas, we can also use electricity(电) to run our cars, but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.Which of these ways will be used to run our cars in the future?68. When might people have to go back to using horses and carriages?A. When they are poorB. When they run out of oilC. When they need more exerciseD. When there aren't any big trees in the world69.
