Unit 21 Yellow Submarine? 黄色潜水艇
The class loaded into the submarine. "Be careful," said their teacher Mrs. Teller. The class was going on to a school field trip under the ocean. Everyone was very excited. When everyone was in and the doors were locked the submarine started to move.
The captain was at the front. There were many windows in the submarine and the students looked out the window at all the interesting things. "Look over here," one boy shouted. "It's an octopus! Wow. It is so big." All the students ran over to where the boy was standing.
The octopus was bigger than the sub. It s long legs could have wrapped around it. The sub kept going deeper into the water. "Look at the school of fish," said another student as the sub sailed through a school of thousands and thousands of fish.
The students looked out and the fish looked in. At the bottom of the ocean the students saw something very interesting. It was a sunken warship. The teacher told them it was from World War 2.
And then it was time to go home. When they got back to school the students wrote a paper about their adventure under the sea.
