My father is a manager,he works in　a company. I admire him very much, he is the centre of our family.[这句不太恰当。如果你想说他是一家之主，最好用he's the man in our family.]My mother does not work , she is a housewife. She does all the cooking and cleaning .Sometimes ,she likes[既然是likes,表示喜好，就不能用sometimes,如果用sometimes就要把likes去掉，把cooking改为一般时态。] cooking　nice　food　with her friends .My sister is a college student ,she is now studying at a university.有点废话。I am a　student [too],I study at [建议改为attend]NO.5 Primary School.
　　I will always love my family, because they are my dear lative[这个词什么意思？有点不妥。].

 

总体错误比较少。加油。
