МНЕ НУЖНО ЧТОБЫ ВЫ МНЕ ПЕРЕВЕЛИ ТЕКСТ.
Sally was 7 years old. She lived in a big house with
her parents. They loved her very much. She had a
beautiful room and many toys. She had good friends
and liked playing with them. But Sally was not happy.
She had a secret.
Sally didn’t do her homework. She didn’t know the
letters of the alphabet, she couldn’t read and write. And
all other pupils in her class could do it very well. When
there was an exam Sally didn’t go to school. She told
her parents that she was ill.
She didn’t want to tell her parents and friends about
her sad secret. She thought: “They will say I’m a bad
girl. They will stop loving me!”
One day, Sally's teacher asked the girl to write on
the board. Sally couldn’t do it. After the lesson the
teacher asked Sally to tell her the truth. Sally said, "I
don’t do my homework. I don't know how to read and
write. I’m sorry!”
The teacher listened to her. She wanted to help
Sally. She told her: "That's ok. I will help you."
So Sally and her teacher met every day after classes.
Sally worked hard.
Soon she could read and write! And she learned a
very important lesson: “There are a lot of good people
who can help you.
