The program is called the Whale Translation Project(WTP)，whose meaning is to know what whales are saying.Its goal is clear but very difficult to achieve.Understanding the communication of whales and other animals could inspire conservation efforts.For example，the discovery that humpback whales sing to each other in the 1960s led to successful conservation activities and laws. The WTP started when Gruber，a biologist at Harvard University，turned to a computer scientist for help about dealing with a large amount of data on whale sounds.They thought of applying machine learning，used for improving human language translations，to whales.The sound of click，similar to a binary code(二进制)，is easy for AI to analyze. Scientists once presented the sounds of a whale using a series of lines to show the number of clicks per second.Now，with the help of AI，Gruber can quickly turn the thousands of whale sounds from hours of recordings into a new kind of pictures that look like musical notes.This method helps to find tiny differences in the sounds.Gruber can use AI to analyze the differences and the specific context，like the behavior of moving to the surface and hunting for food，and thus understand the meaning of the whale sound easily.He can also discover how whales interact，getting 99% right in predicting(预测) the next click. This kind of work isn’t limited to whales.Suresh Neethirajan，a computer science and agriculture professor，studies how farmers can use real-time observation to explain animal behaviors.He collects data，such as body temperature，paired with recorded sounds and videos，to understand whether animals are comfortable or not.With AI，he can recognise sick animals quickly，improving their well-being. 1．What is the purpose of mentioning the discovery in the 1960s? A．To show the success of protecting the environment. B．To explain the difficulty of saving humpback whales. C．To stress the value of studying animal communication. D．To introduce the challenge of understanding whale language. 2．How can AI help according to paragraph 4? A．It records whale sound quickly. B．It processes sound data effectively. C．It reads musical notes correctly. D．It promotes whale interactions directly. 3．What can we learn about AI according to the last paragraph? A．It cures diseases of animals. B．It improves farmers’ well-being. C．It aims to change animal behavior. D．It helps to understand animals’ needs. 4．What is the main idea of the passage? A．Scientists develop machine learning. B．Scientists discover a new whale sound. C．AI creates a unique type of musical note. D．AI unlocks the secrets of animal language. 语法填空 A team of Chinese researchers has made a significant breakthrough in the field of artificial intelligence(AI) by developing a new technology，Social Behavior Atlas(SBeA)，according to the Shenzhen Institute of Advanced Technology(SIAT) under the famous Chinese Academy of Sciences.This 1. (advance) technology greatly improves the correctness of detecting(检测) and analyzing(分析) animal social behavior. The most difficult part of multi-animal social behavior analysis is to recognize the difference between animals that look very similar at 2. same time.The SBeA technology is capable 3. identifying similar-looking animals with more than 90 percent correctness,4. is achieved without the need to define social behavior categories(类别) ahead of time.As a result，the technology allows researchers 5. (discover) new and previously undefined aspects of animal social behavior.Besides，the SBeA technology can also 6. (effective) process a large amount of data.Therefore it can 7. (apply) to cross-species studies. The 8. (message) of this groundbreaking study were recently published in the journal Nature Machine Intelligence,9. (stress) the potential(潜在性) of AI in advancing our understanding of animal behavior.This research not only opens new ways in the study of animal social behavior but also 10. (show) the great abilities of AI in scientific research. 高一年级英语必修2 Unit3校本作业 第1页·(共 25 页) 学科网（北京）股份有限公司 $
