Brainly is a question-and-answer website. Its stated purpose is to give homework help, but unfortunately, many visitors don't use it that way. Most questions are posted by elementary-, middle-, or high-school students, and most of their questions come from their homework assignments. Responses to the questions are posted by a wide variety of volunteers, from other students to professional adults. Some of the responses do include helpful explanations. Sadly, many don't. Far too many of the responses consists of only an answer, with no explanation. Others consist of a wrong answer accompanied by a wrong or unhelpful explanation. Finally, the site is characterized throughout by an ominous fact: After more than a year in its existence, not a single ad has appeared yet. No website can exist indefinitely without some revenue, and it's doubtful that this one can survive much longer without some major changes. The "elephant in the room" is the question: <em>Should</em> it ?
Auxiliary verbs form the mood or tense of the other verbs in the sentence. There are three primary auxiliary verbs in the English language and these are: be, have and do.
