Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.
Traditional migration paths take birds through countries that are not protecting locations to stop, rest and feed.
The scientists studied the migration, or flight, paths, of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.
The major danger for migratory birds is development. Building and paving has covered over nature where birds stop and feed as they move from one part of the world to another.
For example, a bird called the bar-tailed godwit migrates from its breeding grounds in the Arctic. It flies all the way to the southern hemisphere in Australia and New Zealand. Along the way, the small birds stop at Yellow Sea mudflats in China, North Korea and South Korea.
One of the scientists who worked on the study says "many of these critical sites have been lost to land reuse owing to urban, industrial and agricultural expansion."
5. Why are bird species in danger according to the news report?
6. What do we learn about migratory birds from the news?
7. What is the reason for the lost of critical sites for migratory birds?
选项
A、They change traditional migration paths.
B、They generally live in dangerous areas.
C、They are losing their habitats.
D、Their habitats are not protected.
答案
C
解析
新闻开头提到,因为鸟类的栖息地正在消失(because their habitats,or homelands,are disappearing)。C中的losing与disappearing同义,故正确。A“它们改变了传统的迁徙路线”,新闻只是说在它们的迁徙路线中有许多危险的区域,并没有说鸟类改变迁徙路线。B“它们主要住在危险的地区”中的dangerous areas在新闻中是说鸟类迁徙会经过许多危险区域,不是说它们住在危险区域。D“它们的栖息地未受到保护”,新闻中鸟类危险的直接原因是栖息地的消失,“未受到保护”是后文的阐述,并不是直接原因。
