Oil is so important that it is sometimes called “black gold”. Almost half our energy      from oil. We use it to run our cars and factories and to      our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you      your hands with might also be made from oil. Children’s plastic toys are made from oil.

Oil is        to find, because it is deep under the earth. Today, however, we have many      to find oil. One tool measures (测量) the pull of gravity (重力). Places where gravity is weaker are more likely to have oil.      tool measures sound waves. Sound waves travel      different kinds of rocks at different speeds. We can use      to find the rocks that have oil in them.
