每句都认真看了,我从语法和语言习惯两个方面给你进行了修改,希望及时采纳.
My mother has been doing a lot of things for me不符合语言逻辑,改为过去式即可.
most importance humans改为most important people in my life.英语中基本不会用in my heart这样的短语,它和中文不一样.
she is forty years old,and she is a worker.建议整合为一句.she is a 40 years old worker.
改My mother is every beautiful.中every为very.
Now her hair is long and straight.这样符合习惯用语.
英语中不要每句开头都用My mother,适当用she代替.food之后的一句就可以改为watching soap opera with me is her hobby.
去掉后面and we watch soap opreas every day.
But I think they are（改为it's） very boring!
My mother does breakfast for me every day放在cook delicious food一句之后,这样连贯.
In order to provide with hot breakfast she has to get up early every morning.
.and she is every care about my study整句话都错了,is是多余的,改为and she cares about my study very much.
.She often help(helps) me (改为in) study
She is very strict(with me)!
My mother do(did) lots of things for me but I never do(did) anythings for her.
!So I make(i've made) a decision
.I am going to help my mother to(去掉to) do the dishes .
,I only want to say(这句改为 all I want to say is);" Mom,I love you !"
