To this point we have only worked with information questions that have been formed with
verbs that can be inverted: modal auxiliary verbs, helping verbs, and be as a main verb Now we
will look at information questions that require do There is nothing actually different about these
questions, except that having to insert do adds one more step to the process Let us start again
with the two movement rules:
1 Move the interrogative pronoun to the fi rst position in the sentence
2 Invert the verb and subject
Between these two rules, we need to apply the do insertion rule That is, we insert do before
the fi rst verb and transfer the tense of that fi rst verb to do We then apply Rule 2 in the normal
way Here is an example:
Do insertion: When they did leave.
Trang 3Note that did has picked up the past tense from left, causing left to revert back to its base form,
leave.
Here are several more examples using the do insertion rule:
Do insertion: Where you do want to go (Note that do is in the present tense)
Do insertion: Why they did turn the offer down.
Do insertion: How often you did call them about the meeting.
Exercise 13.9
Change the following statements to information questions using do insertion and the two
move-ment rules
I missed what.
Do insertion: What I did miss.
1 They claimed how much in damages.
2 He demanded to see whom.
Trang 43 The decision depends on what.
4 Your cats reacted to your new dog how.
5 The kids want to do this weekend what.
6 You rented which movie.
7 She got to the offi ce when.
8 Roberta picked whom for the advisory committee.
9 You think that you will pick whose health plan.
Trang 510 They plan to stay in Los Angeles how long.
The way information questions in English are formed differs in two important respects from the way information questions are formed in nearly all other languages Most languages convert
statements to information questions by moving an interrogative pronoun to the fi rst position in
the sentence However, as you know, English also requires that the subject and verb be inverted
and that we insert do if there is no other suitable helping verb to be the tense-carrying verb Thus
English requires two extra steps, both of which are complicated Given that the process of
form-ing information questions in English is both unusual and complicated, it is not surprisform-ing that
mistakes in information questions are among the most common mistakes of nonnative speakers,
even fl uent ones who rarely make other kinds of mistakes In the following examples, the subject
noun phrase is in italics and the helping verb is in bold
Error Standard
X When they will be back? When will they be back?
All of these mistakes result from stopping the process of converting statements to information
questions after doing only Rule 1: move the interrogative pronoun to the fi rst position in the
sen-tence To correct these errors, speakers need to apply the do insertion rule (if necessary) and then,
most critically, apply Rule 2 and invert the subject and the fi rst, tense-carrying helping verb
Exercise 13.10
Correct the errors in the left column and put the corrected form in the right column
Error Standard
1 When the program will start?
2 How I am doing?
3 What we have missed so far?
4 How much they are charging for it?
Trang 65 Why he had so much trouble?
6 How early we could fi nish here?
7 Where we sign up for the program?
8 Whose advice you are going to follow?
9 What song they were singing?
10 How many parts I should order now?
11 What subject you teach?
12 What the problem was with my phone?
13 How they will recognize you?
14 When they should take the test?
15 Why the government requires that form?
Up to this point we have ignored one type of information question: questions in which the
interrogative pronoun plays the role of subject Here are some examples with who playing the role
of subject with all the different types of verbs:
Who will take care of the children?
Who has had lunch already?
Be as main verb: Who is the visitor?
Who was Alfred Smith?
Who answered the phone?
As you can see, these information questions seem to break all the rules: there is no inversion of
subject and helping verb, and in the last pair of examples, do is not used when there is no helping
verb Obviously, there is something special that happens when the interrogative pronoun plays
the role of subject
Basically, the two rules do not apply when the interrogative pronoun is the subject To see why this is the case, let’s start with the following statement and try to apply the two rules:
Who should go next.
Trang 7Rule 1 does not apply because the interrogative pronoun is already in the fi rst position in the
sentence If we apply Rule 2, we will produce an ungrammatical question because we will put the
subject after the verb as though we were trying to create some strange form of yes-no question:
X Should who go next?
Thus, we cannot apply either Rule 1 or Rule 2 when the interrogative pronoun is the subject of
the sentence When the interrogative pronoun plays the role of subject, the underlying
state-ment is already in the correct fi nal form for an information question and no further changes are
needed (or even possible) Since only nouns can play the role of subject, the kinds of interrogative
pronouns that can be subjects are necessarily limited to the following:
Here are some more examples:
Nouns
Who told you the answer?
What do you mean by that?
Which is the right one?
Possessive nouns
Whose computer did you use?
Which train should we take?
A particularly diffi cult problem for native and nonnative speakers alike is choosing between
who and whom in information questions For example, which of the following is correct?
Who did you want to see?
Whom did you want to see?
To determine which one is correct, we have to undo Rule 1 and move the interrogative pronoun
back to where it came from:
By undoing Rule 1 we can see that who is the object of the verb see Since it is an object pronoun,
we must use whom rather than who Thus, the correct form of the information questions is
Whom did you want to see?
