Задание:
Выразительно прочитайте стихотворение. Какие предложения по цели высказывания в нем встречаются? Объясните свою точку зрения.
Миг.
Не привыкайте к чудесам -
Дивитесь им, дивитесь!
Не привыкайте к небесам,
Глазами к ним тянитесь.
Приглядывайтесь к облакам,
Прислушивайтесь к птицам,
Прикладывайтесь к родникам, -
Ничто не повторится!
За мигом миг, за шагом шаг
Впадайте в изумленье.
Все будет так-и все не так
Через одно мгновенье.

Somebody special

My grandfather's name is Salvador. He was a farmer but he has retired. He's eighty-six, and he's the oldest of my relatives. Last year my grandmother died, so he came to live with us.

He's very tall and quite fat and he's got grey hair and a beard. He's got blue eyes, and he wears glasses. He usually wears a jacket and trousers, and at weekends when he goes out he always wears a tie.

I think he's wonderful. He's very strong and he's never ill. He's really active, and although he's retired he works hard in our garden and in his fields. He's young at heart and friendly to everyone. People who meet him always love him.

He loves walking in the country and reading. He spends most of his time reading novels and newspapers, and now he's studying French too. When he was young he learnt French in prison during the Civil War and now he wants to remember it again.

When I'm old,I'd like to be like my grandfather. He's a very special person
