Thank you so much. I wrote just a part of my examples. By the way, what does mean ''break sounds natural''? I couldn't find in Longman or on the Internet.
Sorry, the phrase isn't "break sounds natural". It is "I don't think that your sentence break / sounds natural". I meant that I would not have broken it into two sentences. So the "sentence break" was the point at which you put a full stop and chose to start a new sentence. Please note that I have no idea if that is proper terminology - I might have made it up!
