三、阅读理解
A young boy is crying because his ear hurts. Then a man comes out of the forest. He carries some juice from a white mushroom (蘑菇). Carefully, he puts the juice into the boy’s ear.

Now scientists travel by boat, by air, or on foot to rainforest villages. Then they spend long hours learning from the local doctors about the plants which can be used as cures.
