　　 Most of us use oil in some way, and it is difficult to 　1 　the modern world without oil. But oil is not easy to find and get 　2 　the earth. Men must 　3 　the rocks carefully. When they think that the rocks in a 　4 　place may contain oil, a metal tower is built.

　　 A 　5 　in the tower gradually cuts a narrow hole 　6 　the ground . As the 　7 　is made, a steel pipe is pushed down to 　8 　the sides from falling in , and to keep our water. At last , if the men have judged correctly, the hole reaches the 　9 　. Usually the oil rushes up the pipe with 　10 　by the pressure of the gas in the top of the layer of rock, and it streams high into the 　11 　. If this oil 　12 　a light, there would be a terrible fire. A kind of lid is 　13 　the top of the pipe, and the oil is allowed to flow out 　14 　through taps.
