mMy fFavorite cCountries

Titles need to be capitalized

iIf iI haved the choice iI willould absolutely choose European countries, iI think my reasons are very clear .

1. Since you’re talking about something hypothetical, you have to use the conditional tense
2. Whenever you use the word “I” it must be capitalized
3. European what? If you’re just referring to Europe, you should just say “Europe”, but since you talk about counties in Europe in this passage, you should say “European countries” instead

fFirst, Europe in general is a big union that includinges the biggest and strongest economies in the world.

1. Whenever you’re talking about reasons in a list, a comma should come after the ordinal number
2. When you have more than one adjective describing a noun, you need to add “and” in between them

sSecond, the European uUnion has a beautiful view and a wonderful weather as example. Switzerland, n and New Zeealand, island are examples of this.

1. The word “Union” should be capitalized because it’s part of a name
2. Normally we don’t say “a weather”, it sounds unnatural
3. The last part of your sentence was really confusing so I rephrased it to sound more natural. I’m not sure what you were trying to do with the word “island” though. Were you trying to say “The New Zealand island”?

Sow in my opinion i see, I think that the European uUnion is the best place to travel to.

Some slight re-wording to make it sound more natural

mMy favorite countries

Titles are either in title case "My Favourite Countries" or sentence case "My favourite countries". A title in sentence case is seen as more casual than one in title case.

iIf i have the choice iI will absolutely choose a European country, iI think my reasons are very clear .

The original prompt had this mistake too, but "European" is an adjective, so really needs to be paired with a noun like "country"

fFirstly, Europe in general is a big union including the biggest, strongest economies in the world.

sSecondly the European union has a beautiful viewscenery and a wonderful weather as, for example in Switzerland, new Zeeland, isthe island of Zeeland.

"a beautiful view" would refer to one place with good scenery.

"New Zealand" is the country on an island off the coast of Australia. Did you mean Zeeland, the province in the Netherlands?

I'm not sure if you were calling Zeeland an island (it's more than one island), or if you were referring to Ireland or Iceland with "island".
