解答 答案是making；本题考查非谓语动词做结果状语；动词不定式做结果状语表示"出乎预料的、令人沮丧的结果"；现在分词做结果状语表示"顺其自然的或自然而然的结果"；本题中工厂将烟排放到空气中，"很自然的结果"是空气变脏；故答案是making．

The chimp didn’t feel well. She fell over, ignoring the other wild chimps. Finally, the sick chimp crawled over to a bush, picked some leaves and swallowed them. By the next afternoon, the chimp was as good as new!
Biologists watching the chimp were surprised. Somehow, the plant had cured the chimp! Did the chimp know the plant would make her feel better? Or was it just a lucky accident?
Many scientists don’t think it has anything to do with luck. They’re discovering that some animals seem to use plants to cure themselves. And these animals are leading scientists to new plants that could cure humans!
Dr. Richard Wrangham, an anthropologist at Harvard University, agrees that animals may know something we don’t know about forest plants.
Wrangham got to know chimps and their diets while studying them for three years in Tanzania. “You must know a lot about an animal’s feeding habits to know what it doesn’t consider food,” Wrangham explains. Every morning, he saw that most chimps ate fruit near their nests. Later on, they ate on leaves.
When he noticed chimps eating the leaves of a plant they usually ignored, Wrangham thought something interesting was going on---especially when he saw that they’d sometimes walk for 20 minutes to find the plant. Another strange thing that caught his eye was how they ate the bitter leaves.
“They swallowed the leaves whole,” explains Wrangham, noting that chimps usually chew their food well. “They seemed to rub（摩擦）the leaves around the roofs of their mouths. They closed their eyes, wrinkled their noses and swallowed slowly. ”
Wrangham wondered what could be so good about something tasting so bad. He had a chemist analyze the leaves. He discovered that the leaves contain a red oil that kills different viruses（病毒）. Later tests showed that the oil might even fight cancer and the AIDS virus!
Why don’t the chimps chew the leaves? “Rubbing the leaves between the tongue and the inside of the mouth might allow the chemicals to enter the bloodstream directly,” he suggests, “instead of going to the stomach, where they might get destroyed by acids. The chimps seem to know what they’re doing.”
