 阅读理解The bald eagle was once a dying species in the United States. This is because the bird wasn't always held with respect. At the National Book Festival, author Jack E. Davis detailed the bald eagle's "great conservation success story". The bald eagle has faced extinction twice. The first occurred in the late 19th century. "It was then that a bald eagle seen was one to be shot," he said. He explained that the bird had been regarded as a dangerous animal, and considered a threat (威胁). But such threat tended to be overstated (夸大). Throughout the early 20th century, thousands of bald eagles were shot down. Things began to change for the bird in 1940, when the government passed its legal protection—the Bald Eagle Protection Act. However, only five years later, the bird faced its second near extinction when DDT, an environmentally harmful insecticide (杀虫剂), was introduced at the end of World War Ⅱ. In 1963, the bald eagle hit its lowest number—totaling less than 500 nesting pairs across the U. S. "At that time, only about one-third of the nation's water was safe for swimming and fishing," Davis said. "That was eagle habitat, but also our habitat. " "We stepped up. " He mentioned that this situation led a nonprofit organization, Fish and Wildlife, to launch "hugely successful" eagle protection projects. By 2007, the bald eagle was removed from the list as the species regained its health, reaching nearly 11,000 nesting pairs nationwide, and today's number is somewhere around 500,000. For those looking to assist in the ongoing comeback of the bald eagle and other endangered animals, Davis said, almost every state has a center that accepts donations and welcomes visitors and volunteers.  （1） What made the bald eagle almost extinct for the first time? A . The illegal hunting. B . The loose control of guns. C . The attack from other animals. D . The misunderstanding of their threat. （2） What caused Fish and Wildlife to start eagle protection projects? A . The outbreak of World War II. B . The overuse of DDT nationwide. C . The disappearance of eagle habitat. D . The worsening of eagles' living condition. （3） What's the main purpose of the passage? A . To tell a story of a dying species. B . To advertise the book of JackE. Davis. C . To raise the awareness of protecting wildlife. D . To introduce the ways of protecting bald eagles. 答案： D D C
