There's an unwritten rule among documentary film-makers—to watch, but not intervene (干涉). But a BBC documentary worker in Antarctica made a hard decision.
In one of the Dynasties series, mother penguins can be seen leaving babies behind when they can't get out from the ravine(深谷). Some babies died from the freezing low temperatures.
After a storm, the workers returned to the area and decided to do something. They built a ramp(斜坡) to help the remaining penguins climb to safety.
"We chose to intervene with the least influence," said the show's director, Will Lawson. "Once we'd dug the little ramp, we left it to the birds. We were excited when they used it."
"It's very rare for the film workers to intervene," he said. "But they realized that they might be able to save some of these birds simply by digging a few steps in the ice."
"It's such an unusual condition to do this," he added. "It wasn't dangerous. You weren't touching the animals and by doing this, they had the chance to get out of the trouble."

1. C 【点拨】根据第二段中“mother penguins can be seen leaving babies behind when they can't get out from the ravine(深谷)”可知，企鹅被困在深谷里。故选 C。
2. C 【点拨】根据第二段中“mother penguins can be seen leaving babies behind when they can't get out from the ravine(深谷)”可知，首先是企鹅妈妈把它们的孩子留下了，所以④排在第一位；根据“Some babies died from the freezing low temperatures.”可知，一些企鹅宝宝死于极低的温度，所以②排在第二位，由此可以排除 A、B、D 项。故选 C。
3. A 【点拨】根据倒数第二段中“save some of these birds simply by digging a few steps in the ice”及最后一段中“It's such an unusual condition to do this”可知，this 指代“在冰面上挖几个台阶”这件事。故选 A。
4. C 【点拨】根据文章内容可知，BBC 纪录片的工作者为了救出企鹅而不得不打破常规。这件事情告诉我们，人们有时不得不打破规则来做正确的事情。故选 C。
