Passage A

Source 1.1

1 Leatherback turtles are large turtles that live in the oceans. They are called leatherback turtles because their shell is soft, not hard. They travel from warm waters to cold waters each year to find food.

2 What do leatherback turtles do? Where do they go? How do they find food? Scientists came up with a way to find out more about these turtles. With help from some fishermen, the scientists attached cameras to the backs of some turtles. Then they watched.

3 Leatherback turtles can weigh between 500 and 2,000 pounds. Their favorite food is jellyfish. Turtles need a lot of food, so they dive down deep to search for their meals. They usually dive around 300 feet for about 20 minutes. However, some can dive down 4,000 feet and stay there as long as 85 minutes!

4 The cameras gave a lot of information that was previously unknown. They showed that the turtles made shallower dives in cold water. They also found that they got most of their food on their way up from the dive. Scientists believe they can see the jellyfish easier as they look upward because the jellyfish look darker against the sunshine.

Passage B

1 Yogi Berra was one of the best baseball players of all time. He was a catcher for the New York Yankees and played for 17 years.

2 Yogi was born in 1925 in Missouri, and he grew up playing sports. His family had money problems, so he dropped out of school in the eighth grade to help them. A few years later, he started playing for minor league baseball teams. In 1946, the New York Yankees discovered his talent. He became the starting catcher for the team.

3 Yogi was a very good catcher and liked to distract the batters. He also liked to talk a lot during games. When a good hitter came to the plate, he started chattering. He hoped to break the batter’s concentration so he would make a mistake. Ted Williams, a great batter, once told him to be quiet so he could work!

4 As a batter, Yogi was terrific. He struck at almost any pitch, no matter how bad it was. But he very rarely struck out.

5 As famous as Yogi Berra is for baseball, he may be better known for things he said, such as “It ain’t over ’til it’s over.” He also said: “A nickel ain’t worth a dime anymore” and “Nobody goes there anymore. It’s too crowded.” One sports reporter thinks Yogi’s funniest saying of all time was, “If you don’t know where you are going, you might wind up somewhere else.”
