The concept behind "would" has always been difficult for my students to grasp. They can memorize the rules of the second conditional well enough, but the hypothetical aspect always seems to be puzzling. The following activity has clarified the topic greatly, amid a lot of laughter. I presented two pictures of remote places, Antarctica and Namibia. I wrote on the board: If you were there… The first question was:" …what would you feel?" That seemed a reasonable question to the pupils.
