The cost of an item is not a continuous action. It is a present state.
Student or Learner
atm im preparing for the C1 language certificate. I guess/hope i'm quite familiar with the basic structure of grammer, but there is 1 thing i really dont understand:
present simple usage: - general truths, current habits, permanent situations, etc.
present continuous: - actions happening now ( and around now), temporary situations, etc.
Now i had to deal with the following task: Circle the correct word or phrase:
Each song only costs / is only costing 50 cents at the moment because they're on special offer.
No denying, "is only costing" just sounds stupid, but according to my grammar book, its a temporary situation, and there is also the keyword "at the moment" .. so i chose it.
Well, i looked up in the solution: the right answer is "only costs"...
Is there any rule i disregarded? Or can just somebody explane it to me? It's driving me crazy aaaah xD
Thx a lot! simon
Prices may well change, but they're constant for given amounts of time. 'At the moment' is a reference to the current price state.
However, it's still not a temporary change. Once it does change, it's going to maintain that state for a while, which leads to Mike's explanation.
Thank you guys, "I" see things more clearly now.
And thank you teechar for your constructive and theme based contribution.. you got the point ;)
