这句话有没有语法上的错误,怎么改正?

Gina,her grangma and her parents are in her family.（缺少连词）
She likes playing volleyball and tennis for sports.(play sth.for sports)
Pink and blue are colors she likes.(宾语是colors)
再问： 如果是Gina喜欢volleyball和tennis怎么说
再答： 一般说喜欢某项球类运动，而不是喜欢球本身。 所以应该用 like playing volleyball 而不是 like volleyball 但 tennis 可用于表示 网球运动。 所以改为这样： She likes tennis and playing volleyball.
