Нужен перевод , пожалуйста помогите! Disabled people want equal treatment not charity. Indeed the idea that people with disabilities are weak and helpless is simply not correct. They just can't do some things other people are able to do .But there are many things they do mush better than others. For example there are some amazingly strong and telented personalities including writers and sportsmen who are blind and actors even composers who are deaf. One example is Eduard Asadov . He was no different from his classmates when they had their last school party. The Great Patriotic War began a week after they had granduated from secondry school.Despite his age Ednard became a soldier on the second day of the war . But in 1944 he was badly injured abd became completely blind . However Eduard didn t give up . He entered the Institute of Literature and soon his poems became very popular . He wrote about people and their feelings , love ,friendship and betrayal , and other aspects of life . his poems were pure and encouraging . They helped people cope with their troubles and hore for the best . Ever strong and optimistic Asadov helped oter people see the beauty of the world , though his own eyes were blind .
