文档简介
Passage 1
The study of bird brain evolution has long been a fascinating yet challenging area of research. Scientists have been eager to understand how bird brains transformed from their dinosaur - like ancestors. (1)____ This discovery has shed new light on this evolutionary journey.
The fossil, named Navaornis hestiae, was in an excellent state of preservation. (2)____ By creating computer images of its brain and inner ear structures, scientists could analyze its unique features.
(3)____ Its bill and eye shape resembled those of modern birds. However, its brain presented a mix of modern, ancient, and intermediate elements. For example, the size of its cerebellum was more like that of Archaeopteryx, while the connection between its brain and spinal cord was similar to modern birds and humans.
Navaornis also had a special characteristic. (4)____ This might have given it enhanced balance, which could be related to its flying ability.
Although Navaornis lived during the Cretaceous period and didn't survive the asteroid strike, its discovery is crucial. (5)____ It helps us piece together the complex puzzle of bird brain evolution.
A. Its inner ear organ for balance was larger than in any other known bird.
B. It provides valuable insights into the development of bird brains.
C. The discovery of a well - preserved skull fossil in Brazil was a game - changer.
D. Scientists were able to conduct in - depth research on it.
E. The Navaornis skull had some interesting features.
F. Bird brain evolution is a complex process that requires more research.
G. The fossil was found in the southeastern Brazilian state of Sao Paulo.
答案：(1)C (2)D (3)E (4)A (5)B
Passage 2
The evolution of bird brains from their dinosaurian origins is a mystery that has intrigued scientists for years. (1)____ The newly - discovered Navaornis hestiae fossil is a significant step forward in this research.
The Navaornis fossil was found in Brazil in 2016. (2)____ This allowed scientists to create detailed computer images of its brain and inner ear, providing a window into its neural and sensory capabilities.
When examining the Navaornis skull, scientists noticed distinct features. (3)____ This combination of features indicates an interesting stage in bird evolution.
(4)____ This larger inner ear could have been an adaptation for better balance during flight. Scientists believe, based on the examination of the remains, that Navaornis was a good flyer.
(5)____ Even though it didn't directly lead to modern birds, it gives us a better understanding of the parallel evolution of bird - like features.
A. Its brain showed a combination of modern and ancient traits.
B. The fossil's excellent condition was a boon for scientific study.
C. The discovery of this fossil is a major milestone in the field.
D. Navaornis had a unique characteristic in its inner ear.
E. Scientists have been working hard to uncover the secrets of bird brain evolution.
F. The Navaornis lived during the Cretaceous period.
G. The study of this fossil can help us understand the past better.
答案：(1)E (2)B (3)A (4)D (5)C
Passage 3
Scientists have long been puzzled by the evolution of bird brains from their dinosaur - like forms. (1)____ The Navaornis hestiae fossil, discovered in Brazil, is helping to solve this mystery.
The Navaornis fossil was in remarkable condition. (2)____ This enabled scientists to study its brain and inner ear structures in detail.
(3)____ Its brain was smaller relative to skull size compared to modern birds but larger and more complex than Archaeopteryx's. Also, the cerebellum was different from modern birds, yet the brain - spinal cord connection was similar to modern species.
Another interesting aspect of Navaornis was its inner ear. (4)____ This might have been an important adaptation for its lifestyle.
(5)____ Although it didn't survive the asteroid strike, it provides valuable information about the independent development of bird - like features.
A. The inner ear organ for balance was unusually large.
B. This fossil discovery is a key piece in the puzzle of bird brain evolution.
C. It was a significant find that could answer many questions.
D. The well - preserved state of the fossil was a great advantage.
E. The Navaornis skull had a mix of old and new features.
F. The study of bird brain evolution is full of challenges.
G. The Navaornis lived side - by - side with different dinosaurs.
答案：(1)F (2)D (3)E (4)A (5)B
