My English teacher
My English teacher is Miss Zhang.She lives in Jiawang.She has the（把这个the去掉,不需要说two.用上the表示特指,这里说她有…,就不用了） big eyes,（这里把逗号去掉加上and she,因为前面已经有一个动词has了,用and,并列）is very beautiful.On the class（这里改为In class,同样也不用加the）,her talk is full of humour.We are very like her.（最后一句改为We all like her very much.因为like作为喜欢的意思时,本身就动词,不用is）
修改之后：
My English teacher
My English teacher is Miss Zhang.She lives in Jiawang.She has big eyes and she is very beautiful.In class,her talk is full of humour.We all like her very much.
三年级写成这样很不错!
