Put each of the words on the left in Exercise 1 above in the correct space in the following conversation.​

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.
