讲座
1. What is the main purpose of the lecture?
To show why synurbization is a growing problem
To explain the genetic differences between rural and urban animals
To discuss some of the ways that animals change when living in urban environments
To point out the factors that limit an animal’s ability to thrive in urban environments
2. What does the professor imply when she discusses rural and urban populations of
a species of mouse?
The synurbic mice are unlikely to evolve into a new species.
There are no significant behavioral differences between the rural mice and the synurbic mice.
Researchers are concerned that the synurbic mice may be a danger to the environment.
Not all researchers are convinced that the synurbic mice are evolving into a new species.
3. According to the professor, why do some synurbic species no longer migrate? （多选题）
They face fewer predators in cities.
Urban development has destroyed many of the geographic cues they needed in order to migrate.
They are able to find warm areas in cities in winter.
Food in cities is often available year-round.
4. Why does the professor mention feeding pigeons in the park?
To give an example of behavioral change in a synurbic animal
To explain why some animals are only partially synurbic
To suggest a reason why most synurbic animals have a long life span
To explain how a research study was done
5. Why does the professor discuss the peregrine falcon?
To give an example of a species that failed to become synurbic
To show that synurbization has been used to conserve endangered species
To show that both predator and prey animals have synurbic properties
To warn about the problems species face when they become synurbic
6. According to the professor, what problem might occur as a result of some species
having become successful at synurbization?
People might underestimate the danger that some animals pose to humans.
People might overlook the impact of urban growth on species diversity.
Population growth in some species might become difficult to control.
Unnatural behavior in some species might become more common.
