    There is not enough oil in the world now. 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 to run our cars,but first we must make the electricity!Some countries have coal (煤) 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 (祸轮机) and make electricity more easily and cheaply.
