1. When a parallel structure is used, words make a pattern because the same structure is repeated. For example, sometimes a noun is repeated: ‘My favourite cities are London, New York and Edinburgh.’ In this example, the parallel structure comes from having three nouns (London, New York and Edinburgh) repeated. Sometimes a verb (in the same tense) is repeated. For example, ‘Don’t eat and talk at the same time!’ In this case, the parallel structure comes from repeating two bare infinitives (‘eat’ and ‘talk’).
2. Look at this example from The Cook (Chapter 2) can you find examples of parallel structures?
