我是个初一的学生,请各位大神看一下我的英语作文有没有错误.
Hello,everyone!Do you know me?My name is Yu Jiale.I’m 12 and my birthday is on August 23rd.I’m a Chinese boy and I live in Chongqing with my family.Do you want to know my family?Now,let me tell to you about my family.
I have a small family.There are four people in my family.They are my grandmother,my parents and I.My parents has gray hair.She always cooks some delicious food to me.My father is an engineer.He is tall and thin.Sometimes,he is too stern but he is usually kind to me.My mother is a housewife and she helps with my study.I’m a Grade 7 student of No.8 Middle School and I’m my parents’ only child.So they love me and I love them very much,
This is my family.I like it very much.

答案

let me tell to you about my family.应该是tell you,也可以说成talk about my family
has gray hair-->have gray hair
She always cooks some delicious food to me-->...for me
he is too stern but he is usually kind to me这句是正确的,但后面的he is可以省略以避免重复
I like it very much这也是对的,不过按习惯会把family当成其成员,这里用them指代.
