Are these three sentences true? What's the difference?
1. The world is worth it.
2. The world is worth.
3. The world is worthy.

Question

Answer

There is a difference between the word, "worth" and "worthy".

You can measure a persons "worth" by the amount of money and property that he owns.
A person is "worthy" if you think he deserves your time, respect and care. A poor person can still be "worthy".

The world is worth a great deal. It has great value in resources like water, minerals and clean air.
Caring for the earth is a worthy cause. It is a project that deserves our time and serious attention.

Hope this helps

Answer

They are not true or false sentences.  The second statement is not a complete sentence.
1. The world is worth it (what)?
2. The world is worth (what)?
3.  The world is worthy (of what)?

Answer

#2 is grammatically wrong...
#1.  值得
#3.  偉大, 賢達

Answer

Honestly, I think all of them sound kind of awkward. Maybe you mean to say "The world is precious"? Or "sacred"?
