Exercise – Present Perfect Or Past Perfect Or Past Simple — Developing Result Now Or Result At A Past Defined Moment?

    hide

    commentary

    For “start” and “end” the actions of the verbs have results at the defined moment “when we got to the stadium”.

  2. Up until that day, he ____________________ (to always be) on time for meetings.

    show answer

    had always been

    hide

    commentary

    At the defined moment “that day” there is a result from the activity of the verb (perfect “on time” record, or considered very dependable, for example).

  3. He ____________________ (to pass) the state exam for law in 2008.

    show answer

    passed

    hide

    commentary

    Past perfect doesn’t fit because there is nothing happening before the moment of passing the exam, so we don’t have something happening before something else. The present perfect also does not fit because while we may sense that we have some kind of result, there’s no context given in which passing that exam is a part of a developing result. So the past simple is the correct tense for this sentence.

  4. While we were in the tip of Argentina, we ____________________ (to run) into a colony of penguins.

    show answer

    ran

    hide

    commentary

    “Run into” has a meaning like to “come across” “encounter” etc. Everything is in the past in this one, with no connection to the present, so the answer will be either past simple or past perfect. The answer is past simple because we don’t have something happening before something else, but one thing happening in the course of, during, in the middle of something else, and therefore, do not have the past perfect condition.

  5. I ____________________ (to work) on this email all this morning. It’s 11:30 already.

    show answer

    have worked

    hide

    commentary

    From the statements made and words used, we know that it’s still morning and that most likely we haven’t finished writing the email. We therefore have a result that is developing at the present moment and should use the present perfect.

  6. That trip was her first time on a plane. She ____________________ (never actually to fly) before that.

    show answer

    had never actually flown

    hide

    commentary

    The first sentence gives us our defined moment, and before this defined moment we have a result (count of flights, travel history biography, the novelty of flying, etc.) that results from her having not flown.

    hide

  7. He ____________________ (to never see) the northern lights, but thinks that they must be a lot more impressive to see in person than in photos or video.

    show answer

    has never seen

    hide

    commentary

    The activity of the verb, “not having seen” has a result (the count of the number of times seen, his things seen biography, the novelty that the experience would still offer him, ect.). The result is now and still developing – the latter, because he presumably can still see them. If he were blind at the time speaking or serving a life sentence in a prison nowhere near where the northern lights phenomenon ever occurred with little hope of being escape or transfer to a prison in close enough proximity, then the past simple would be the more appropriate because in this case, the result would not be developing.

  8. When we got to the theatre, the last performance ____________________ (to just end), so the area was crowded with people leaving.

    show answer

    had just ended

    hide

    commentary

    At a defined moment “got to the theatre” we have a result “crowded area” from a prior action “end”.

    hide

  9. I ____________________ (to not wash) my hair in days, so it’s starting to get noticeably greasy.

    show answer

    haven’t washed

    hide

    commentary

    We have a result now from the verb “wash” not happenning – count of the number of days not washed.

    hide

  10. My hair was starting to get greasy a few days ago because I ____________________ (to not wash) it for days before that.

    show answer

    had not washed

    hide

    commentary

    At a past defined moment “a few days ago” we had a result from the action of a verb prior to that moment “not washing” – the conditions we look for for the past perfect.

  11. ____________________ (to end up) going to the event last night?

    show answer

    end up

    hide

    To “end up” doing something means that you followed through with some plans or intentions. There are no conditions for either the present or past perfect here – no developing result and no result at a defined moment from a prior verb, so we are describing a simple past action and use the past simple.

  12. She didn’t want to think about tenses any more because she ____________________ (to already study) them so many times, but she ____________________ (to find) the right system and the Nth time was the charm.

    show answer

    hide

    had already studied / had found

    commentary

    This, hopefully, is the experience you are having with my learning system. At least this is my intention. “Nth” is a term we us in match to describe the last event or observation in a series. At our defined moment “didn’t want” we have results from the prior actions “study” and “find” (tense fatigue and it being worthwhile to study tenses one more time), so the past perfect, and only the past perfect, fits.

  13. I ____________________ (to have) too much to drink. I think I’m drunk.

    show answer

    have had

    hide

    commentary

    We have a developing result now, which is the amount that I have had to drink, and so should use the present perfect.

    hide

  14. I ____________________ (not to drive) home, but took a taxi, because I’d had to much to drink.

    show answer

    didn’t drive

    hide

    commentary

    The trick in this problem is to see that “not to drive” is for the defined moment – the past perfect part being given later in the sentence (‘d had).
