Hello,everyone!There's a sentence in my teaching book like this: But there wes a man......that made me wonder if he might not have something interesting to tell.Why there's a "not" in this sentence?is there any grammar mistake in it?thank you!
No, the sentence is fine; it's a stylistic variant, and means the same as it would mean if there were no "not"!
This may seem confusing; but consider these two sentences:
1. I wonder if there is a bottle of beer in the fridge.
2. I wonder if there is not a bottle of beer in the fridge.
#1 implies two possibilities: 1) beer in the fridge 2) no beer in the fridge.
#2 also implies two possibilities: 1) no beer in the fridge 2) beer in the fridge.
Thus both #1 and #2 imply the same two possibilities. The only difference is in the emphasis: in #2, on the absence of beer; in #1, on the presence of beer.
(I feel suddenly thirsty.)
