The controversy statement that American's airport left far away from other countries' airports

America's airports are awful

After selected as the USA president, Donald Trump proved his controversy statement that American's airport left far away from other countries' airports, albeit it is tremendously right. Although the USA is the most powerful country in the world, Skytrax's data revealed that several well-knew airports such as New York JFK and Los Angeles ranked 59th and 91 the respectively in the world. Meanwhile, the best airport is Changi Airport, which has achieved such prestigious reward over the last three years.

Lincoln, I think that you need to learn more about collocation. Your sentence structure seems quite confusing due to inappropriate collocation that you put carelessly in the summary. For instance, when you write the word "right" it is not supposed to be collocated with "tremendously". The appropriate adverbs that can be collocated with the word "right" are absolutely, dead, exactly, just, quite , almost, more or less, nearly . Apart from those lists, you cannot put ANY adverbs before the word "right". It might look simple but it becomes one of the essential grading criteria in an IELTS test.

When it comes to grammatical range and accuracy, I think you have forgotten your high-school English subject about Gerund. If you still remember, your former teacher definitely said that "if you put a verb after preposition, its form will definitely change into an -ing form". For example, in your summary you wrote "After selected as..." it should be "After being selected as..." as simple as that.
