Wh - Questions
Wh- Questions allow a speaker to find out more information about topics. They are as follows:
Other words can also be used to inquire about specific information:
The "grammar" used with wh- questions depends on whether the topic being asked about is the "subject" or "predicate" of a sentence. For the subject pattern, simply replace the person or thing being asked about with the appropriate wh-word.
For the predicate pattern, wh- question formation depends on whether there is an "auxiliary" verb in the original sentence. Auxiliary or "helping" verbs are verbs that precede main verbs. Auxiliary verbs are italicized in the following sentences.
I can do it.
They are leaving.
I have eaten my lunch.
I should have finished my homework.
To make a question using the predicate pattern, first form a yes/no question by inverting the subject and (first) auxiliary verb. Then, add the appropriate wh- word to the beginning of the sentence.
If there is no auxiliary and the verb is "be," invert the subject and verb, then add the appropriate wh- word to the beginning of the sentence.
If there is no auxiliary and the verb is not "be," add do to the beginning of the sentence. Then add the appropriate wh-question word. Be sure to "transfer" the tense and number from the main verb to the word do.
