A United Effort
One October during the Cold War, two gray whales were swimming near Alaska. It was time for them to go to Mexico for the winter. But these two whales didn’t leave in time, and they were trapped under the ice. Some Inuits, the native people of Alaska, tried to help. They cut large holes in the ice so the whales could breathe. But the ice stretched for kilometers around them. It was too late. Now it was impossible for the whales to escape and move south. The Inuits knew that they needed an icebreaker. An icebreaker is a special boat that can cut a pathway through ice.
An environmentalist contacted the U.S. Coast Guard. But they had only two icebreakers and both were too far away. In the meantime, the whales had been trapped for almost two weeks. The Inuits knew that in situations like this the whales usually died. So the environmentalist sent a message to the Soviet Union. He asked if a Soviet icebreaker could come. The Soviets agreed. One of their icebreakers was nearby. The environmentalist immediately contacted the U.S. government. They quickly cooperated, the Soviet icebreaker was on its way, and the U.S. government sent a team to Alaska to meet it. The Americans gave the Soviets detailed photos of the area and they made a plan together.
Finally, the icebreaker reached the whales. A path had been cleared! It took a couple of days for the whales to make it through to the open sea. But then they were safe. It’s unusual to see countries involved in a Cold War working together, but saving the whales brought the Americans and Soviets together as teammates.
What is this story mostly about
a. Separating. b. Cold wars.
c. Saving whales. d. Finding peace.
Forming Opinions: What Do You Think
A: Guided Writing
1. A student writes his opinion of the story. Find two sentences that don’t belong and put a line through them.
A United Effort
“A United Effort” is a really interesting story. It is about a whale rescue, and it is also about politics. The story happened during the Cold War, when the USSR and the U.S. didn’t get along. I’m really interested in politics and want to be a politician. When each country realized that some whales might die if they didn’t cooperate, they set aside their differences and worked together. I like working with other people because the work goes faster. Sometimes people can see that there are some things more important than politics.
2. Fill in the blank with the best word.
This student thinks ___________ is more important than politics.
a. the Cold War b. the U.S. c. cooperation d. difference
B: Exchanging Your Ideas
I think… I feel…
I’m against… It depends…
1. Why do you think the whales didn’t leave in time
2. Why do you think the Soviets agreed to come and worked together with Americans
In my opinion… I believe…
I don’t think… Because…
