You are given a set of words.
You are also given some sentences with input boxes, and you are required to use the words to complete the sentences correctly.
You can put your chosen word into the input box by first clicking on the word and then in the input box.

PET - NEVER BEFORE - FIRST TIME
I have never BEEN HERE BEFORE, means two things:
- I am here now, and, this is my FIRST TIME here.
So a sentence using BEEN HERE BEFORE can be transformed into a sentence using MY FIRST TIME.
- I have NEVER eaten snails BEFORE.
- This is THE FIRST TIME I am eating snails.
