In my 18 years of life,there have been many things.University days are the best part of them.I can never forget the days when I stepped into my university.I was impressed by its garden-like campus,its enthusiastic students and especially its learning atmosphere.I at once fell in love with it.
After the arduous military training,I get absolutely absorbed in my studies.The classes given by the teachers are excellent.They provide us with information not only from our textbooks but from many other sources as well.They easily arouse my insatiable desire to take in as much as I can.
Frankly speaking,at first I had some difficulty following the teachers.However,through my own efforts and thanks to my teachers' guidance,I made remarkable progress.Now I've benefited a lot from lectures and many other academic reports.

at 13 years of age,my parents and i visited an eye surgeon (外科医生).as i sat in the examining chair,the doctor looked into my eyes,shining a bright light."she did inherit(经遗传得的) it," he said with coldness."there is no cure."
my father carried a gene (基因) causing blindness.i’d gotten the gene since my birth.he gradually lost his eyesight and so did i.at last we were both completely blind.at that time,he was 57 years old,but i was only 30.
my world fell apart (***) as the darkness fell,destroying the dreams my husband and i had for us and for our three little boys.but when i tried to find some hope and strength,my eyes were opened to a new realization.
my father had given me not just failing eyesight,but an example of determination in the face of trouble as well.we were all living in bolivia in 1964 when he decided to move the family to america.he and mom worked tirelessly to win the right of living in the us.
alone in the states,he overcame his helplessness and lack of fluency in english to rent a small apartment,and buy airline tickets for my mom,my brother and me.
decades later,as an american citizen,i looked back at what he’d taught me.he set an example proving that determination is crucial to success.his journey taught me valuable lessons for dealing with my blindness.
i did the same as i stepped into a dark world.my father’s example made me gain confidence and learn to be thankful for what i had.in this way,now know how to continue life as a wife,mom,sunday school teacher,spanish court interpreter,inspirational speaker and writer.
what i inherited from my father helped me to see my life with a more meaningful glow.
