But since childhood, she had been dreaming of working closely with animals in Africa. “All through my childhood people said you cant go to Africa. Youre a girl,” Goodall says. “But my mother used to say, if you really want to, theres nothing you cant do.” In 1957, the 26-year-old Goodall journeyed to Kenya to work as a secretary. She also arranged to meet the famous scientist Louis Leakey, who was so impressed by her enthusiasm that he hired her as his assistant. She went with him on many trips to the African jungle and in 1960 Leakey sent Goodall to live among chimpanzees (黑猩猩) in a remote animal preserve (禁猎地), recording the animals behavior and interactions. For three months Goodall made little progress. But she says, “1 never came close to giving up.” Her breakthrough came one day when she saw a male chimpanzee stick a blade of grass into a termite (白蚁) hill, then put the grass in his mouth. Afterward she approached the hill and did the same. Pulling the grass out, she discovered dozens of termites clinging to it. The discovery that some animals use tools was unknown to most scientists at the time. Goodall saw chimpanzees exhibit human-like emotions, such as jealousy and love. But she also discovered they were capable of violent attacks against each other. Goodall received her Ph. D in the study of animal behavior at Englands Cambridge University. Now she travels around the globe raising money to preserve wildlife. “I love being in the forest with the chimps,” she says. “Id much rather be there than traveling around from city to city.”(1).What was Goodalls childhood dream? _.A.She dreamed of going to college.B.She dreamed of studying animals in Africa.C.She dreamed of
