Double negative (双重否定)A double negative is a grammatical construction (结构) occurring when two negatives are used in the same sentence, like not uncommon, not an unusual sight (Text, Unit 2), etc. In standard English, two negatives are understood to produce a weakened affirmative (肯定语). Thus not uncommon means rather common and not an unusual sight means quite a usual sight. Similarly, the sentence in the text What I learned from my short experiment was actually not too unlike what Miller learned (Para. 8) is also a case of double negative, meaning What I learned from my short experiment was actually quite like what Miller learned.Pick a word from the box below and complete the sentences with a double negative construction.unattractiveunrealisticuninterestingunrelatedunusual1.
