Dear Teacher,
I meet the sentence in a novel:
"Beverly gave me a smile then, but it had a hard edge to it."
What's the meaning "it had a hard edge to it"? Who does "it" refer to? Please explain.
Another kind of question: How to pronounce all kinds of abbreviations? Could we pronounce their letters one by one? For example, the abbreviation of Maryland is MD, Can we read MD? pp. (pages)? How to pronounce the signs "/" and "&" in sentence? For example: Do you wish to email and/or snail mail? Radio & TV online.
Thanks in advance.
