Mågic màgic coat
Oh no, I need my cout I can't ride without a coat in
this cold weather and Aldar
You can have my fur coat instead, and some money,
too said the bai.
I can't sell my coat, said Aldar. My mother made it
for me
The hai really wanted to have the coat. You can have

It was a very cold day in winter. Aldar Kose had a coat,
but it was old and there were holes in it. He was poor.
and he had no money to buy a new coat. Aldar looked
at his horse. The horse was old, too, and it was very
slow
"I need a warm coat, and a faster horse, he thought.
D
Aldar looked at the bai's beautiful white horse. OK
he said. The bai gave him his fur coat, his horse and a
bag of gold. Aldar put on the new coat, took the gold
and jumped on his new horse. Then he turned to the
bai and said: 'I forgot to tell you that this magic coat
only works when I wear it. Goodbye. And he rode off
as quickly as he could!
c
No I'm not. I've got a magic coat."
A magic coat? But your coat has a hundred holes in it!
said the bai.
"They are magic holes. The holes let the cold air out.
and I stay warm.
I want to have a magic coat, too thought the bai. Do
you want to sell your coat to me?" he asked Aldar Kose.
E
Then he saw another rider in the distance. When the
rider got closer, Aldar recognised the local bai. He
had an idea. He opened his coat, took off his hat and
started singing cheerfully.
'Hello, Aldar Kose, said the bai. 'It's so cold today
Aren't you cold?​

Фраза "хорошо подвешен язык" не очень подходит для cover-letter.
"Я считаю, что заслуживаю [...] надежды" тоже не очень понятно на любом языке.
"Я готов начать работать с начала июля, потому что у меня в конце мая... "  тоже не вяжется.

Я перевёл как есть.

Hello!

I am writing to apply for the position of an employee at the "Teaspoon" restaurant. I visit it from time to time. I'd like to work because I need money for some personal affairs.

I am a 16-year-old, average height person. I want to work for you and not the other restaurants, because I support healthy eating.
I have no work experience, however, in the summer in the country, I learned to cook and adapted a little to kitchen. I also have sleight-of-mouth, so I'll keep promoting the restaurant among my friends. I believe that I deserve your trust and hope, but sometimes I'm not patient enough.
I'm ready to start working starting the beginning of July, because in late May I'm done with school and my summer vacation starts then. I hope to work for 2 months.

I’d like to speak about my friend Andrey and his flat.Andrey is fourteen. He lives with his parents not far from our school.Andrey has a lot of hobbies: he likes to play the computer, to read detective stories, to collect matchboxes. He has a large collection of them.Andrey has short, light hair and gray eyes. He is quite short and rather thin. He always manages to be cheerful, energetic and full of life. My friend is also reliable, shy and hard-working. He is helpful and honest.Andrey is very popular. He is a helpful person and every time he tries to do his best to help somebody when he has some problems. Andrey is very attentive to his parents.Of course, he has some drawbacks - sometimes he is a bit stubborn. But I still like him as he has a good sense of humor and pleasant to deal with.He lives in an old flat in the Lefortovo. It is a three-room flat of a typical block of flats with a lift. His flat is on the fourth floor. His flat consists of the living-room, his parent's bedroom and his own room.Andrey use his room as a study and a bedroom. His room is a very comfortable one. It has its advantages, though it is the smallest room in his flat. The only window in his room faces the green park, which is situated near his house. It is so nice to look out of the window in a bright sunny day! The view is really wonderful.The walls of his room are papered in a design of gray and silver stripes and the curtains on the window match the wallpaper perfectly. The built-in furniture doesn't take much space in it. There is a modern writing table with a reading-lamp on it. He always keep there his notes, text-books and pencils. On the little table there is a cassette recorder. You see, he is a fond of music and often enjoy listening to the lovely melody.His bed stands near the standard lamp. There are two water colors and his portrait on the wall above the bed. The floor in Andrey’s room is covered with a thick carpet. Besides, he grows a lot of flowers. You can see them everywhere: on the window-sill, on the bookcase, on the little table, on the walls...To cut the long story short, I should admit that his room is very attractive and I like it very much.
