One afternoon little David was playing with his friends in the street when he was hit by a motorcycle．He fell and broke his arm．And he was immediately taken to a hospital．There a doctor operated on his arm and put it in a cast(石膏)-David couldn't move it at all．
“
You must keep your arm in the cast for a month,”the doctor said．“That will give your arm a chance to become healthy again．”
At the end of a month David went back to the hospital．The doctor cut the cast and took David's arm out of the cast．
“
Can you move your arm, David?”he asked．
David tried to move his arm．At first it was difficult, but soon he could move it easily．
“
Yes, it's fine,”he said．“Thank you very much．”
“
In a few days it will be as good as new,”the doctor said．“Just exercise it a little．”
“
Will I be able to play the violin?”David asked．
The doctor smiled．“Of course you will,”he said．“You'll have no problems．”
“
That is good news,”David said happily．“Because I couldn't play it at all before．”

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．
