Example: "It will be sunny in London today."
By using London as the subject and removing the it-dummy-subject it could be rephrased into: "London will be sunny today."
This can rarely be done in german so it sounds very confusing.
The sentence we had a debate about was really odd, though.
"Four people can sleep in this tent."
My prof rephrased that into: "This tent sleeps four people."
So, native speakers, I need your help. Does this sentence sound weird to you as well? Do you think it is grammatically correct? And most importantly, would you say that?
