Can you imagine the very first modern Olympics in 1896 with no landing mats(海绵垫), no stopwatches and no photo finishes?In fact, cameras and stopwatches were not used until the 1932 Olympic Games in Los Angeles, USA．Thanks for technology, Olympics have been developing at an unbelievable speed．
Today technology has completely changed sports．Take sports equipment for example．Electronic eyes hanging at the starting lines, together with digital cameras, could catch correct race time and also help to catch runners who “jump the gun”．As runners cross the finishing line, special digital cameras can also easily decide the winner．The days of “dead heats” are gone．
Technological developments are also good for athletes．New sports suits, which get less wind effects, can help cut up to one-tenth of a second from runners’ race time．Top athletes, like Liu Xiang, are even provided with hand-made sports shoes．These shoes are made to fit the athlete exactly－and there are some more changes in the shoes that meet each runner’s personal needs．
Technology has also changed the way of many sports．Take one example－the pole vault．The landing mat makes a big difference to the vaulting style as athletes no longer need to worry about hurting themselves as they fall．Without these worries, athletes could jump higher．New swimming pools have been used to help swimmers swim with easier effort and sports scientists have worked out a new swimming style to improve the speed．
The increasing technological developments have led many sportsmen to suggest that the “Olympic spirit” is being lost in a rush to break records and win medals．Many developing countries say that technology has become too important in sport and that athletes from developing countries are disadvantaged．There are no easy answers but one thing is sure－we cannot turn back times．Technology cannot go backwards．

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．
