Understanding Dyslexia
1 Dyslexia (诵读困难）is a type of learning disability. A person with a learning disability has trouble processing words or numbers. There are several kinds of learning disabilities; dyslexia is the term used when people have difficulty learning to read，even though they are smart enough and want to learn. Dyslexia is not a disease. If s a condition that you are bom with, and it often runs in families.
2 Research has shown that dyslexia happens because of the way the brain processes information. Pictures of the brain, taken with modem imaging tools，have shown that when people with dyslexia read, they use different parts of the brain than people without dyslexia. These pictures also show that the brains of people with dyslexia don't work efficiently during reading. So that’s why reading seems like such slow， hard work.
3 If you have dyslexia, you might have trouble reading even simple words you've seen many times. You probably will read slowly and feel that you have to work extra hard when reading. You might mix up the letters in a word, for example，reading the word "now" as "won” or "left" as "felt." Words may blend(混合）together and spaces are lost. You might have trouble remembering what you've read. You may remember more easily when the same information is read to you or heard on tape.
4 Although dealing with dyslexia can be tough, help is available. Under federal law, someone diagnosed with a learning disability like dyslexia is entitled to extra help from the public school system. A child or teenager with dyslexia usually needs to work with a specially trained teacher, tutor, or reading specialist to learn how to read and spell better.
