I think they can be used interchangeably. For instance, if you're trying a new recipe you could say, "I'm giving it a try" or "I'm going to try it out" Or if you're trying to encourage someone to do something. "Give it a try!" "Try it out!" The only difference I can see is for "try outs" That's when you compete to make a team. "She wants to try out for cheerleading." "He tried out for basketball."

I'm not very familiar with the medical term, but "bosom" generally refers to a persons chest. So I would guess that "hematocele in bosom" is blood collected inside the chest cavity.

Sometimes people add the phrase "thank you very much" to the end of sentences when they think the statement is obvious. For example the Dursley's were obviously normal and it didn't need stating, but because it was stated the author added "thank you very much" to show how they might be offended in having to tell you they were normal. "I'm not conceited, thank you very much." "I know how to change a light bulb, thank you very much." It's a little similar to the word "duh". "I know what a stop sign is, duh!" Except "thank you very much" is more polite and less juvenile.

introducing myself

Hi. Me name is Melina and I'm 13 years old. I'm Iranian and I LOVE learning English.
I've studied English for 7 complete years but still I think I'm not good enough in speaking and writing. I really want to speak it fluently and write it without mistakes.
I tried my best but after a while I found that I'm tired of reading grammer and vocabulary books. When I found italki, I realized that it is really perfect and enjoyable and I really like it!

Your written English is very good. 

I agree, grammar and vocabulary books can be boring.  What helped me to improve my written English when I was younger was reading stories that I liked.  It was helpful with learning new vocabulary and figuring out grammar.  italki is good too.  :)  Have fun with your language learning!

I speak English well, but when an English speaking person talks to me in my restaurant it's difficult to understand him. I want an accent like the boys in London have. And, of course, I would like to have a correspondence with an English speaking person from London.

 

Good luck!  I hope you find a language partner from London.

China and porcelain use different techniques in manufacturing, but basically they are the same thing. They are both ceramics.
