The document appears to be notes about elliptical constructions in English. It provides examples of how to use words like "too", "so", "either", and "neither" to combine two similar sentences that share the same action or activity. It discusses the use of these words with sentences using verbs, modal verbs, the auxiliary verbs "have" and "has", and when an additional verb like "do" or "does" is needed. Several examples are given for positive and negative sentences.
