I want to ask you a few short questions...
1. What is difference between "a pirat" and "a Rover"?
2. What are analogues of the word "think" can I use?
3. Can I say "The sun AMONG" the sky"? Or I must to use "IN" (sky)?
4. Can I say "I was walking near the river"? Or I have to use "ALONG"?
5. What is difference between "must' and "have to"?
