I ............ (see/seeing) Julia in the hallway. Want me to get that file from her? [Summit 2, pp. 11, Joan Saslow and Allen Ascher]
I don't know why the answer is only 'see' and 'seeing is wrong. Is 'see' a stative verb?
What about 'I am seeing Julia in the hallway....' in this example?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
VERY generally, we do tend to say "I see a ship on the horizon" not "I am seeing a ship on the horizon."
VERY generally, we do tend to say "I hear music coming from that room" not "I am hearing music coming from that room."
VERY generally, we do tend to say, "I smell something amazing! What's for dinner?" not "I am smelling something amazing..."
If we use the progressive tense, it suggests a temporary situation (Okay, now I'm seeing the ship... no, it's out of focus again... okay, now I'm seeing it clearly) or something otherwise unusual (I'm smelling something foul... let's find out where it's coming from.)
You will be taught first that these verbs are not used in the progressive (for the present) and then you will learn the exceptions.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
So, the general rule says the simple present tense talks about an action that happens always. The present progressive tense talks about an action that is happening now (future plan is not our issue here.)
Sense verbs are not usually used in progressive sense, when you are talking about ongoing actions: I see a ship on the horizon; I listen to music; I smell a nice smell.
An exception: If you use the progressive tense, it suggests a temporary situation that is coming and going, OR something strange.
