Dear editor,

       Yang fan is one of the best students in our school , who is excellent at his studies , especially at English . He has been awarded many times by out school . He is always ready to help others and has a strong will and self-confidence.

       Unfortunately, he has been refused several times to enter the university he is longing for because of his disability, though he has achieved good results in the examinations . We all think it unfair for the disabled not to have the equal right to go to university. We do hope the whole society can care for them and help them to realize their dreams.

                                                                  Yours
