TAG QUESTIONS Question tags are grammatical elements that are placed at the end of a sentence in the form of a short question and whose structure is opposed to the previous sentence. That is, if a sentence is affirmative, the question tag that accompanies it will be negative, and vice versa. For example, in: Your son is growing up so fast, isn't he? The first sentence states that the son is growing very quickly, while the final question is phrased in a negative way. The two main rules for forming question tags are that when a sentence is affirmative, the question is negative. While when a sentence is negative, the question is positive. Affirmative sentence + negative question tag. You like ice cream, don´t you? Ana plays the piano, doesn´t she? You work very hard, don´t you? We don´t have classes, do we? She ate lobster, didn´t she? I turned off the projector, didn´t I? She is an artist, isn't she?
