Almost everyone in the world uses oil in some way. Cars, buses, planes and many trains and ships also need oil. Even our bicycles need oil. Indeed the whole world would stop if there was no oil. Today there is a growing need for oil in the world. So people are looking for it everywhere. They look for oil in deserts, in the mountains and under the sea. Quite often they find nothing, but the search for oil always goes on. Who are the largest oil producers in the world? The U.S., the former Soviet Union, and the countries of the Middle East. But China is catching up fast. Before liberation we used to buy nearly all our oil from the U.S. Many foreign people said China was "oil-poor". But since liberation oil has been found in many parts of the country. Today everyone agrees that China is rich in oil. Our oil will not only meet the great need in our country, but also be sold to other countries.
