English translation might be either
"The strawberry has a sweet aroma"
"Strawberries have a sweet aroma"
Given the context of "Stroberi" (Strawberries have...) in the example sentence I would assume All Strawberries...have a sweet aroma. And the shorthand might be that "Strawberries smell sweet" or "Strawberries have a sweet smell".
This one is completely unnatural, although I can't explain why...
It's because strawberry should be plural.
Strawberries have a sweet smell is not right ?
