问题 问答题

试述教师的角色冲突。

答案

参考答案:教师在履行工作角色时常产生角色冲突。教师在工作中,要将许多角色加以融合和组织,也常常遇到两个角色同时为他提出两种相反的角色行为的情况。这是教师在日常教育工作中普遍遇到的大量的冲突。教师在多种工作角色之间冲突时,一时很难在对立中找到统一,只有否定一个才有可能满足另一个,只有否定一面才能肯定另一面。教师作为一个具体的“人”,有他自己的原来面目,教师作为一个社会角色,也有他进入这个角色后的扮演。作为一个教学情境中的“我”,尽管不完全是自然中的“我”,但要是一个真实的“我”。如果一个教师以“超等教师”这一角色来约束自己,就不会与自己的教育对象融为一体。

California Condor’s Shocking Recovery

California condors are North America’s largest birds, with wind-length of up to 3 meters. In the 1980s, electrical lines an d lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training 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 for the night, they just don’t 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 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 animals 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 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.

Rideout’s team thinks that the California condors’ average survival time in the wild is now just under eight years. “Although these measures 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. ”

A.are active at night
