What did the scientists find about the blue whale?
For the first time ever, scientists have recorded the heart rate of the world’s largest creature: the blue whale. To get this reading, they attached an electrocardiogram device to the body of a whale. They found that the mammal’s heart rate can slow to just two beats a minute as the animal searches for food below the surface of the ocean. The highest heart rate they recorded was 37 beats a minute after the whale returned to the surface for air.
选项
A、It is now on the verge of extinction.
B、Its heart rate can be measured very accurately.
C、Its heart rate slows down when it is underwater.
D、It is the world’s largest living mammal.
答案
C
解析
题目问关于蓝鲸,科学家们发现了什么。 新闻开头提到科学家有史以来第一次记录到了世界上最大的生物——蓝鯨的心率。“They found that the mammal’s heart rate can slow to just two beats a minute as the animal searches for food below the surface of the ocean”,即科学家发现当蓝鯨在海面以下寻找食物时,它的心率可以减慢到每分钟两次。由此可见,当蓝鯨在水下的时候,它的心率减慢,故选C。
