有错改正：my brother（don’t like summer ），（because it‘s）hot

don't --doesn't

my brother does't like summer because it's hot.

My brother doesn't like summer,because it's hot.

my brother doesn’t like summer ，for it' s hot

my brother doesn't like summer, because it is hot .
brother是单三，所以在加否定词要用单三形式，do,does都是助动词，加not变否定词

don’t不对 应该是doesn’t
