Today we’ll talk about reading．When we read a text，our eyes move across a page in short，quick movements．We recognize words usually when our eyes still fixate(停留，凝视)．Each time they fixate，we see a group of words．This is known as the recognition span or the visual span(视幅)．The length of time for which the eyes stop varies from person to person．It also varies within any parson according to his purpose in reading and his familiarity with the text．In addition，it can be affected by such factors as lighting and tiredness.

Unfortunately，in the past，many reading improvement courses have concentrated too much on how our eyes move across the page．As a result of this misleading emphasis(强调)on the purely visual aspects of reading，many exercises have been designed to train the eyes to see more words at one fixation．For example，in some exercises，words are flashed on to a screen for a tenth of a second．One of the exercises has required students to fix their eyes on some central point，taking in the words on either side．Such word patterns are often formed in the shape of pyramids(金字塔)，so the reader takes in more and more words at each successive（连续的）fixation．All these exercises are very clever，but it' s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently.Reading requires the ability to understand the relationship between words．Consequently，for these reasons，many experts have now begun to question the usefulness of eye training，especially since any approach which trains a person to read isolated(孤立的)words and phrases would seem unlikely to help him in reading a continuous text．

No one knows exactly how many disabled people there are in the world，but estimates suggest the figure is over 450 million．The number of disabled people in India alone is probably more than double the total population of Canada．

In the United Kingdom，about one in ten people have some disability．Disability is not just something that happens to other people：as we get older，many of us will become less mobile，hard of hearing or have failing eyesight．

Disablement can take many forms and occur at any time of life．Some people are born with disabilities．Many others become disabled as they get older．There are many progressive(逐渐的)disabling diseases．The longer time goes on，the worse they become. Some people are disabled in accidents．Many others may have a period of disability in the form of a mental illness．All are affected by people’s attitude towards them．

Disabled people face many physical barriers．Next time you go shopping or to work or visit friends，imagine how you would manage if you could not get up steps，or onto buses and trains．How would you cope if you could not see where you were going or could not hear the traffic?But there are other barriers：prejudice(偏见)can be even harder to break down and ignorance represents the greatest barrier of all．It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through，so it is important to draw attention to these barriers and show that it is the individual person and their ability，not their disability，that counts．
