What's the difference between a limited duration, a temporary action and the current trend?
"She is learning English." (Limited and temporary)
"She is working in a bank." (Meaning temporarily but isn't it also limted?)
"They are living in poverty.' (current trend as one of my books says)
Does the first sentence express a limited duration and isn't it also a temporary action? Does the third sentence express the current trend only?
"The current trend" was mentioned in my book "English Grammar in Context" by Michael Vince.
