In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock tra

2、ining and medical treatment are helping to rescue these big birds.In the late 1980s, the last few condors were taken from the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.Electrical lines have been killing them off. “As they go in to rest f

3、or the night, they just dont see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once.So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the

4、birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other a

5、nimals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that

6、 removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011. Rideouts team thinks that the California condors average survival time in the wild is now just under eight years. “Although these me

7、asures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them. ”1.California condors attract researchers interest because they _.A. are active at nightB. had to be bred in the wildC. are found on in CaliforniaD.

30、Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work.The reason why any of us take any risks at all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. 17 As the quality of ri

31、sk-taking was passed from on generation to the next, humans ended up with a sense of adventure and a tolerance for risk.So why arent we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one Killed. A few daring survived, though, along with a few stay-in-

32、the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. 18 No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years.19 To help you do that, your brain increases your hunger for new experiences.
