In recent years, scientists have been increasingly interested in understanding how urbanization influences animal behavior and survival. One notable study, conducted by researchers from the University of Copenhagen, explored how urban and rural bird populations differ in their problem-solving abilities.
What was the primary purpose of the experiments
A. To analyze how urbanization affects animal diets.
B. To determine how human interaction affects bird migration.
C. To examine cognitive differences between urban and rural birds.
D. To study the social behaviors of birds in varying environments.

Intensity exercises often get praised for their role in preventing illnesses like high blood pressure, heart disease, and Type 2 diabetes-not to mention their mental health benefits. But there’s a common mistake: the more intense the exercise, the better the benefits. A recent research shows that low-to-moderate (低到中等的) intensity exercise,such as Zone 2 training,maybe just as-or even more-effective for improving health and endurance (持久力).

Research-finding pattern
In recent years, scientists have been increasingly interested in understanding how urbanization influences animal behavior and survival. One notable study, conducted by researchers from the University of Copenhagen, explored how urban and rural bird populations differ in their problem-solving abilities.
The researchers focused on a species of small birds known as great tits(山雀).These birds were chosen because they are common in both urban and rural environments,making them ideal subjects for comparison. To test their cognitive abilities, the scientists designed a series of experiments that involved food retrieval. One task required the birds to pull a string to access a treat, while another challenged them to slide a lid off a container. These tasks were designed to simulate real-world challenges, mimicking the need to extract food from complex or unfamiliar objects commonly found in human environments.
The findings revealed that urban great tits consistently outperformed their rural counterparts, demonstrating significantly quicker task resolution times. Researchers believe that this cognitive advantage stems from the adaptability required for survival within urban settings. In cities, birds are often exposed to novel objects and situations, such as trash bins and food wrappers, which they must learn to navigate. This ongoing interaction with human-altered environments likely fosters cognitive development over time, enhancing their overall problem-solving skills.
However, this enhanced cognitive ability is accompanied by a noteworthy trade-off.Urban birds tend to be more easily alarmed and display less cautious behavior, resulting in increased vulnerability to various risks, including predation(捕食)and accidents. For example, urban great tits may venture closer to busy roads or unfamiliar predators-behaviors that rural birds typically avoid due to their more cautious nature. Dr. Anders Johansen, one of the lead authors of the study, emphasized that these differences highlight the significant impact of human-altered environments on wildlife and their behaviors.
As urban areas continue to expand, it becomes vital to understand how animals adapt to these changing landscapes. The study underscores both the benefits and drawbacks of urban living for wildlife, highlighting the necessity for further research into how animals strike a balance between cognitive advancement and survival in increasingly urbanized ecosystems. By gaining insights into these dynamics, conservation efforts can be better directed to support wildlife populations amidst the challenges posed by urban environments.

B
30.Why do urban great tits face higher risks
A. They struggle to adapt to new urban challenges.
B. Their environments lack adequate food resources.
C. Their heightened boldness makes them less cautious.
D. They rely too heavily on human-altered environments.
