My mother is the greatest mother in the world, she takes care of all the family chores and she never complains. I know she it is not easy for her to do so, for she gives up her career when she has me, so I am so thankful to her. On this mother’s day, I just want to show her my gratitude and let her know that I love her so much. 
我的母亲是世界上最伟大的母亲,她照料了所有的家庭琐事,她从不抱怨。我知道她是不容易的,因为她放弃了她的事业,当她有了我的时候,所以我很感谢她。在这个母亲节里,我只是想告诉她我的感激之情,让她知道我是如此爱她。

修改后：

My mother is the greatest mother in the world, she takes care of all the family and does the chores by herself, but she never complains. I know it is not easy for her to do so, for she gave up her career when she had me. I am so thankful to her. On this mother’s day, I just want to show her my gratitude and let her know that I love her so much.
