Do (Present Simple) animals have (Present Simple) any unexplained powers we are (Present Simple) unaware of? For many years
pet owners and scientists have reported (Present Perfect) examples of unusual behaviour
in animals. They say (Present Simple) that pets can (Present Simple) anticipate (Infinitive) their owners leaving for
trips or returning home. These animals somehow know (Present Simple) when they are going (Present Cont)
to be fed (Infinitive) or taken for a walk. Does (Present Simple) this mean (Present Simple) anything or is (Present Simple) it just a
coincidence? Maybe it has (Present Simple) nothing to do (Infinitive) with psychic powers, maybe pets
just understand (Present Simple) enough language to get (Infinitive) the message? Surprisingly, little
research has been done (Present Perfect) on these phenomena.
