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)如果是Gina喜欢volleyball和tennis怎么说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.
