Complete the story with past simple, past calontinuous, or past perfect forms of the verbs in (brackets). Did you see that? It happened (happen) when I was on a sailing trip with my school. I (sit) on the boat when a dolphin suddenly jumped out of the water. My classmates and I were thrilled because we (never / see) one before. The dolphin (swim) next to our boat, so everyone decided to take a picture. Unfortunately, someone had put a bag next to my feet and I (not/ notice). So, when I stood up to take the photo, I (trip) over the bag and (fall) into the water. Our boat (move) really fast, but luckily the captain stopped it for me. However, when I got back on the boat, the other students (not / seem) as happy as me: the dolphin (disappear) and everyone (miss) an opportunity to take the photo of a lifetime!

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
