Hey Yuri,

Here are my responses to your questions.

I thought that Nick didn’t like the people he mentioned.
I didn’t understand that he was interested in listening to some of them.

There is another meaning for that sentence. This sentence is too early in the novel to know how Nick feels about the people. This 2nd meaning could be the one that Nick is referring to.

Another meaning:
Curious Natures could refer to interesting wild animals. Nick could imply that these people are similar to watching monkeys in the jungle or at the zoo. Nick could feel that he is better then these animals and sometimes finds them interesting.

Do you speak like people in the story?

The people in The Great Gatsby are high rich society. Most of us do not speak like that. We speak exactly the way we write in this forum, simple and direct.

What’s the difference in English between 20th and 21th century?
I just thought that Fitzgerald was modern enough.
If I write English in his way, if it was possible to me, would I sound like very old?

English is not different between 20th and 21st Century. Fitzgerald wrote about rich people in this book, so they talk like rich people. You would sound very educated if you write English that way.

Most Asians are smart. (50-99% of Asians)
The Asians are smart. (50-99% of Asians)
Asians are smart (50-99% of Asians)  

Do you mean these three have the same meaning?

Same meaning.
