"The study found achievement scores were no higher in classrooms using reading and math software products than in classrooms without the new products". (this is from an artical on CNN.com)
"You're no villager"
I've seen the two above sentences many times,but I wonder if they are grammatically correct? and is it ok if I use this kind of structure in written English?
thanks so much!
They're both fine. However, the structures are different; the first is a negative of a comparative and the second is the negative of a noun.
