A new study tells us about two sea animals: orcas (虎鲸) and dolphins (海豚). They work together to find salmon (鲑鱼) near Canada's coast.
This is not common (常见的) in the animal world. Scientists first found it by accident (偶然). *Later, they used small flying cameras and tags to watch them.
How do they do it? Dolphins swim deep and use sound (声音) to find fish. Orcas follow quietly and listen to the sounds. First, orcas catch a big salmon. Then, they break it into parts for their family. Dolphins eat the small pieces (碎块).
What a great team! This way, both of them get food easily.

答案

1 T 由第一段中的“They work together to find salmon near Canada’s coast.”可知,虎鲸和海豚一起合作寻找鲑鱼。故该句与原文相符。
2 F 由第二段中的“This is not common in the animal world.”可知,这种现象在动物界并不常见。故该句与原文不符。
3 F 由第二段中的“Scientists first found it by accident. Later, they used small flying cameras and tags to watch them.”可知,科学家一开始是偶然发现这种现象的,之后才用小型航拍相机和电子跟踪器观察它们,并不是科学家用小型航拍相机发现了虎鲸。故该句与原文不符。
4 T 由第三段中的“Dolphins swim deep and use sound to find fish.”可知,海豚会游到深处,利用声音来寻找鱼。故该句与原文相符。
5 T 由第三段中的“First, orcas catch a big salmon. Then, they break it into parts for their family. Dolphins eat the small pieces.”可知,海豚会吃虎鲸剩下的鱼肉小碎块。故该句与原文相符。
