Since learning a language is about communication, it is important that students are able to ask and answer questions. When practicing a basic question or sentence structure, model dialogues might sound a bit unnatural so consider using interview type activities instead. Once students have reached a more advanced level, they will be able to have conversations that more closely resemble those of native speakers. With increased vocabulary, conversations will flow more easily and students will be able to come up with a wide variety of answers even when asked simple questions. Never forget the importance of speaking practice in ESL classes.
A question may be either a linguistic expression used to make a request for information, or else the request itself made by such an expression. This information is provided with an answer. Questions are normally put forward or asked using interrogative sentences. However they can also be formed by imperative sentences, which normally express commands: "Tell me what two plus two is"; conversely, some expressions, such as "Would you pass the salt?", have the grammatical form of questions but actually function as requests for action, not for answers, making them allofunctional. (A phrase such as this could, theoretically, also be viewed not merely as a request but as an observation of the other person's desire to comply with the request given.)
