A game for language learners by John and Muriel Higgins
The program shows a short piece of English in which some words or phrases have been altered.
Sometimes the tenses have been changed, or articles inserted or omitted.
Sometimes the style is altered from casual to formal or British to American or vice versa.
You can move a highlight through the text showing you the alternatives at the bottom of the screen.
Pick the one you think the original writer used.
Click Ready when you think you have found all the right choices.
Then compare your answer.
