补充回答: and now i would like very much to introduce my family to you.there are 4 members in my family,including my parents,my younger brother and i.my father is a busineman,he is always busy.he is a person who never over-expresses himself,but he is very concerned about us.he usually makes himself as an example to us.he is a hard-working man,and he concentrates on his career.when he comes back home with the tired body ,i worry about him,so i tell myself that i should work hard at my study as my father and repay him with my good performance.
my mother is a house-wife,she is a kind-hearted and hardworking.she is attentive to my brother and me,so sometimes i consider that she is so bored but when i come back home from school,there is always food prepared for me.my brother is 3 years younger than me ,he is a smart and naughty guy.
my family is very happy ,i love my family.i make up my mind to work hard on my study and get a bright future to repay my parents.
