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.”

Online courses are a terrific way for busy people. 71 You might have a full time job with a packed schedule and need to study at irregular times. You might want to benefit from the quality of education in another country. In this article you will learn about what it takes to succeed in online courses.
72 Time management is an important skill to develop. First, calculate how much time you will need to study every day. Then, allot（分配）a specific time in your schedule for studying. If you are busy during the day, then separate a few hours at night for studies. If you do not schedule study time, chances are you will not get any.
Then, the good place to study can be different from student to student. Some prefer to study in complete silence. Others need some kind of soft music around them to concentrate. 73
It can be easy to get distracted（分散）when it is time to study. One of the most common mistakes students of online courses make is leaving their chat and email accounts open while studying. This may seem like a small distraction, but it can end up wasting a lot of your time. 74
In conclusion, it takes hard work and concentration to succeed in online courses. 75 The more effort you put into learning the course material, the better equipped you will be to succeed in your professional career.

B. There are many reasons you might want to take online courses.
C. In order to succeed in online learning, you have to have some specific skills. D. Remember online courses are designed to give you the knowledge to succeed. E.
