英语 帮我修改一下语法 .
My mother’s whole life is really not easy!My grandmother died when my mother was 9 years old.My grandfather's health was very poor while mom’s two older sisters are married.So only my mom took care of my grandfather at home.Young mother is over her carefree childhood at this time,began to provoke the family.Mother is a very smart and very hardworking student at school,the examination often gets full marks,but the family is too difficult to allow her to continue the study,so my mother had to leave school in tears,that year,she was ten!
.Because all the mothers in the world,their own children will always be the most lovely and most precious!So I have been like a fish in my mother's deep river of the love,so happy to swim.
