1. Simple sentences often have one subject, one main verb and one object. For example, ‘She went home’. However, if the subject is repeated and one action follows another, we can make use of ellipsis, which means we can avoid repeating the subject when we talk about another action that the same subject does.
Instead of writing ‘She went home and she fell asleep’ (or ‘She went home. She fell asleep immediately.), we can remove the repeated subject ‘she’. As a result, the sentence becomes: She went home and fell asleep immediately
2. From The Janitor (Chapter 5) find some examples of this kind of sentence.
