Nowadays more and more people care about the exploitation(开采)of the natural resources, such as oil．Though there're many kinds of resources, with the fast increase of population and the appearance of many more factories, the more we use, the fewer there will be left for the future, Oil is getting less and less year after year．It's said that oil can last for only 50 years．Natural gas perhaps will last about 38 years．
Oil can be used in many ways and it's difficult to imagine what the modern world will be like without oil．But oil isn't easy to find and get out of the earth．Men must study the rocks．When they think the rocks in a certain place may have oil, a metal tower is built．A machine in the tower cuts a hole down into the ground．At the same time, a steel pipe is pushed down to stop the sides from falling in and to keep out water．At last if the men are right, usually the oil rushes up the sides with great force by the pressure of the gas in the top of the rock, and it rushes high into the air．If the oil catches a light, there will be a terrible fire．So a kind of cover is fixed on the top of the pipe, and the oil can run out through taps．
If we make a well near the middle of the oil field, we can also get gas．Such gas is sent through pipes to towns far away and used in houses and factories like coal gas．
Today oil is under pressure as never before．The price of oil keeps rising all the time．In many countries, the governments encourage people to save oil as much as possible．

You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
