* Simple questions
* Modal verbs ("will", "would", etc.)
* Interrogative adverbs ("how?", "when", "why?", etc.)
* Interrogativepronouns ("who", "whom", "what", etc.)
* "Which", "which one"
Simple questions (that is, questions to which one can respond by a simple "yes" or "no") may be formed in threedifferent ways:
1. "Do": one precedes an assertion with "do" or "does" (or "don't" or "doesn't" for a negative expression, or "did", "didn't" for the past):
* Do you want to go to the movies?* Does she work at IBM?
* Don't you travel quite a bit?
* Do they answer questions quickly?
* Didn't they want to eat?
But: One never places "do" or "does" before the verb "to be" orbefore modal verbs in questions; in this case it is preferable to invert the subject and verb:
* Are you coming to the reception?
* Was the meeting boring?
* Weren't you hungry?
2. Inversion: with certain verbs (especially the verbs "to be", "to do", "to have", and modal verbs) questions are formed by inverting the subject and object. (In the case of the verb "to have,"which is usually combined with "do" in interrogatives, inversion signals a literary style.)
* Is Jack home?
* Have you nothing to declare?
* Would you like to go to the movies?
*Will they ever come to visit?
* Can the employees talk to the boss?
* Won't you sit down?
3. Modal phrases: If a modal verb is used in a sentence, or if it is strongly implied, a modalphrase can be used to make an interrogative form. The modal phrase is typically an inversion of the subject and verb, in the negative, repeated at the end of the sentence:
* It's time to go, isn'tit?
* He'd like to come with us, wouldn't he?
* You would like to go with us, wouldn't you?
* You can understand that, can't you?
In the case of a negative question, the modal...
