As population increased in large cities in the 19th century, building subway lines was a way to move people from one area of a city to another quickly．The first main subway system, the London Underground, started in 1863 using steam trains．Subway developed quickly in London and the system then had more lines．As of 1896, it strated to use an electrical system．Today's subways around the world now work on electricity．
Two of the world's earliest subways were built in Paris and New York．When the Paris Metro opened on July 19,1900 citizens were pround of the beautifully decorated station entrances that have been a landmark ever since．Although the first New York subway consisted of only 14.6 kilometers of track in 1904, today it is the world's largest subway system．
Subway trains run in tunnels dug far below the ground．Passengers enter the stations and then take lifts or moving stairs to get on the trains．The deep underground stations of the London and Moscow subways served as safe bomb shelters(防空洞)during World War Ⅱ．Today some cities are building new subways and they dig deep for a different reason．In Athens, Greece, for exmple, the city planners don't want to damage the ancient monument(纪念碑)above the ground．
Today, subways are still popular with passengers．The Moscow subway is the busiest in the world with 3.2 billion riders a year．Close behind are subways in Tokyo(2.7billion), Soul(1.6billion), and Mexico City(1.3billion)．Systems that got started early in London, New York and Paris transport millions of riders, and so do subways in Osaka, Hong Kong, and St．Petersburg．

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．
