Thank you very much. I still have a few more sentences to check.

1)I hate doing shopping (“the shopping”?) and eating Chinese food. I attended the primary and middle schools in Italy. I’ve got a pimply face with a pimply nose and a normal mouth.
2) I’ve got small brown eyes like a Chinese with brown eyebrows. I do some football (better I play football).
3) I like reading war and car books (better: war books and car magazines) and collecting model cars.
4) I dress normal. Better: I wear casual/plain clothes. I live in the country. In the front of my house there is a courtyard with many flowers and trees.
5) In front of and next to my house there are two vineyards while behind there is a field and on the right there is a street.
6) I can see all my town from here (there?) . It’s a very hot and sunny place in the summer. I go to school in London/to London.I have four goldfish (?). I have a cat called Tex. It is like the fourth member of our family.

Merlin told Arhur that if someone wore it,he would never bleed.
But "when someone wore it, he never bled".

Choose 3 or 4...

1) The sentence structure and grammar in these sentences seems mostly correct, with just a few minor changes needed:

- Instead of saying "doing shopping," it is more common to say "going shopping."
- Instead of saying "eating Chinese food," it is more natural to say "I don't like Chinese food."
- Instead of saying "I attended the primary and middle schools in Italy," it would be clearer to say "I attended both primary and middle school in Italy."
- Instead of saying "I've got a pimply face with a pimply nose and a normal mouth," it would be better to say "I have acne on my face and nose, but my mouth is normal."

2) The sentence structure and grammar in this sentence also seem mostly correct, with just a few minor changes:

- Instead of saying "I've got small brown eyes like a Chinese with brown eyebrows," it would be clearer to say "I have small brown eyes and brown eyebrows, similar to those of a Chinese person."
- Instead of saying "I do some football," it would be better to say "I play football."

3) The sentence structure and grammar in this sentence seem correct, but a minor change is needed:

- Instead of saying "I like reading war and car books," it would be clearer to say "I like reading books about war and cars, and I also enjoy collecting model cars."

4) The sentence structure and grammar in this sentence seem mostly correct, with just a minor change needed:

- Instead of saying "I dress normal," it would be better to say "I dress casually."

5) The sentence structure and grammar in this sentence seem correct, but a minor change is needed:

- Instead of saying "on the right there is a street," it would be clearer to say "to the right, there is a street."

6) The sentence structure and grammar in this sentence seem mostly correct, with just a few minor changes needed:

- Instead of saying "I can see all my town from here," it would be better to say "I can see my entire town from here."
- Instead of saying "It's a very hot and sunny place in the summer," it would be more accurate to say "It becomes a very hot and sunny place in the summer."
- Instead of saying "I go to school in London/to London," it would be better to clarify whether you attend school in London or travel there.
- Instead of saying "I have four goldfish (?)," it would be better to say "I own four goldfish."
- Instead of saying "It is like the fourth member of our family," it would be more natural to say "It has become like the fourth member of our family."

Regarding your last sentence, "Merlin told Arthur that if someone wore it, he would never bleed." The sentence is grammatically correct, but if you want to express a general statement, it would be more accurate to say "When someone wears it, they never bleed."
