From Kenneth Beare, English: Know your Auxiliary Verbs! Auxiliary verbs are conjugated depending on the subject of a sentence. Here are a few examples of auxiliary verbs: Tom has lived in Boston for twenty years. Knowing correct auxiliary verb usage is key to tense usage. Every tense takes an auxiliary form of the verb. There are three exceptions to this rule: Simple present positive: She works at a bank. Yes / No answer short forms: Question tags: Positive agreement / inclusion: Here is a quick overview of auxiliary verb usage: DO / DOES Used simple present question and negative forms: What time does he get up? DID Used in simple past question and negative forms: When did they arrive yesterday? IS / ARE / AM Used in present continuous and for the future with 'going to': They are working hard at the moment. WAS / WERE Past continuous: I was watching TV when you arrived. HAVE / HAS Present perfect and present perfect continuous: How long have you lived here? HAD Past perfect and past perfect continuous: He had eaten by the time I arrived. WILL / WON'T Future with 'will': What will the weather be like tomorrow? If you don't understand all of these tenses, don't worry. This overview chart shows the positive, negative and interrogative (question) forms of all the principle tenses in English with a brief description of the principle usage. The timeline tenses chart provides a handy visual reference sheet to English tenses and their relationship to the past, present and future. Included you will find active, passive, simple and continuous forms positioned according to their occurrence in time.
