Form Forming a sentence in the Past Simple is easy. To form a declarative sentence, all you need is the subject of the sentence (e.g. I, you, he, a dog) and the past form of your verb (e.g. was, talked, swam). Questions and negative sentences are only a little more difficult, because they require an auxiliary verb.
