I am writing quiz questions and need two more 'blank fill' questions. I am having the students fill in the blanks with certain words from a list, each word can only be used once, so each question has to be worded so there can be only one possible correct answer. I am stuck on the words "didn't" and "doesn't". The exercises are all in the question form. The words "didn't" or "doesn't" can be located either at the beginning or in the middle of the questions, preferably not at the end; I am doing another section on tag questions.

My problem is that every question I think of can have either word interchanged, depending on the tense. I don't want to get tenses involved in this worksheet.

examples:
Didn't she like his little dog? ("doesn't" also works here)
Which one doesn't she like? ("didn't" also works here)

I'm just drawing a blank here, maybe someone else, some fresh eyes, can come up with a couple suitable questions. Emotion: smile

You can avoid specifying the tense by adding suitable adverbials. You can possibly avoid the affirmative/negative problem by giving more context.

He (buy) the car he wanted because it was too expensive.
Paul (buy) a car last Thursday so he could give it to his son as a birthday present on Saturday.
She (buy) a new handbag every week. I don't know how she can afford such extravagance.
Newspapers have become very expensive, so I (buy) them any more these days.
Mary (buy) special food for her cat; she just feeds it her leftovers.
I (buy) three or four CDs a week now I have a steady job.

hmmm, not option to edit my own post? Really? That makes no sense in this day and age, it is the 21st century after all.

Anyway, after reviewing what I have written so far in my quiz, I found a couple questions that can have two possible answers, and I don't want that. So, here are the words I am using for the blank-fills - do, don't, does, doesn't, did, didn't - and I want 6 blank-fill questions in question form, written so that each of those words can only be used once. I am racking my brain on some of these. I don't want to specify any particular tense, if at all possible.

examples:

1) Do you like little dogs? ("Don't" and "Did" and "Didn't" can also be used here)
2) Does Amy like the white table or the black table? ("did" can also be used here)
3) You didn’t like ice cream when you were a child? ("did" can also be used here)
4) Did you get a new car? ("Didn't" can also be used here)
5) You don’t like them because they’re too sweet? ("Didn't" can also be used here)
6)

The more I look at this the more I think I have no choice but to specify the tense. Emotion: sad

Thanks for the tip. I think I have the questions figured out. Here is what I came up with -

Use the appropriate word to make questions – do, don’t, does, doesn’t, did, didn’t – use each word only once

1) Hey Jim, you do like little dogs, don’t you?
2) Well, she does like the round diamond better, but should I get her a bigger one?
3) He doesn’t like that so why are you trying to give it to him?
4) They did buy that new house, didn’t they?
5) You don’t like them anymore because they’re too sweet?
6) He didn’t buy that car because he thought it was too small?

Of course the bold words will be replaced by blanks on the quiz.

If anyone finds any inconsistencies let me know, I want there to be only one possible answer for each question.
