Это только вариант возможного описания, можно написать и больше или сократить, если захочется.
In this picture we can see a family in the weekend. Little girl play with a dog. She threw a ball to it and wait when the dog will catch it. It seems they are having a great fun. Her elder brother plays basketball. I suppose he is a sportsman. Their mother lay in the chair. She is reading the book. Near her we can see a glass of water. Also I can say that weather is fine: the sun is shining, there are no clouds in the sky, it is not windy.
1The girl and the boy are playing with the ball.
2The cat is sleeping in the grass.
3The boys are building sandcastles in the sandpit.
At 11 o'clock he has a school break.
At 3 o'clock pm he comes back home from school.
At 5 o'clock pm he does his homework.
At 8 o'clock pm he watches TV and has dinner.
Kind, friendly, helpful. Третье слово возможно hello. Не уверена...
