How can "she's an apple" be correct?
To translate "Elle a une pomme" I wrote "she is an apple" which makes no sense in English but was deemed incorrect by duolingo who said it had to be "she's an apple". Still not valid English, since there is no gender designation to objects in English. And even is there were, why is "she's" correct but "she is" wrong. I teach ESL and they are the same
I speak British English (I am from the UK), but we would only contract "she has" to "she's" when we use the present perfect tense. So, we would say something like "she's gone out with her friends" or "she's done her homework for history". We would never contract it to mean "she has" when talking about possession. In that case, we would say it as a whole (she has).
