The document discusses how to form sentences in the past simple negative tense in English. It explains that to make sentences negative in the past simple, we use "didn't" plus the infinitive verb, except for the verb "to be", where we use "wasn't" and "weren't". Examples are provided such as "Last year, I didn't travel to South Africa" and "Twenty years ago, I wasn't a child". The key points are that past simple negative uses "didn't" plus the infinitive verb form, except for the verb "to be" which uses "wasn't" and "weren't".
