I have just watch movie in which I think that they should built the digestive system of that toy , after watching the movie how can I express that sentence like I express it as

They should have made intelligent digestive system of Rand

Which Past tense this is and am I expressing it right ?

  • This is confusing because you use two different phrases to say the same thing; one in your question and another in the highlighted part. It is also difficult to understand exactly what you want to know.

It's a strange example, but assuming OP knows what he means by "intelligent digestive system", and thinks the movie would have been better if "Rand" had one, the correct syntax would be...

They should have made an intelligent digestive system for Rand

...or perhaps more idiomatically,...

They should have given Rand an intelligent digestive system

In the context of fictional characters in books/movies, the author/director effectively plays a god-like role, so he can give attributes to characters as he sees fit. Using make more strongly implies the "Creator" deciding and explaining in detail to the audience exactly how the "intelligent digestive system" works, which wouldn't always be considered necessary.

You could call should have [done something] a past irrealis conditional construction. In this link, it's called a "past conditional affirmative" (as opposed to "past conditional negative" you shouldn't have done that).


What you are saying in your highlighted part is somewhat correct but it's not past tense. If you want to say that in past tense, it would be something like this..

"They had made an intelligent digestive system." - It's past perfect tense...

  • no they didn't made , I want them IF they made it , that thing make more interest in the movie

  • In that case, you cannot say it exactly. All you can do is you can show the assumption that something like that built in past. Like this, "They could have made an intelligent digestive machine" Commented Sep 25, 2014 at 13:20
  • something like that should be build with that robot in the movie
