"in front of you" should also be acceptable, no?
This sentence is simply too long to be used in timed practice - I could hardly type this in English in the time available!
perhaps a bad sentence to use in a lesson? Is the tall woman in front of me or am I speaking about her apples first? Dinaintea indicates the latter but still.
I would prefer sentences that are useful in certain situations. But this!
Not really idiomatic English here, since 'I am speaking' is not acceptable, and that's actually how a native English speaker would say it.
