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(材料). 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.
We need
oil, and we are using up the oil wells(井) we know about.
we must find new ways of looking for this “black gold”. Can you do anything for it?
