For a long time, people believed humans were different from all animals. They thought only humans could make tools and have real conversations. Then came Jane Goodall. As a child, Jane loved watching animals in her garden. She would sit for hours observing (观察) how birds built nests and squirrels collected food. This early love for nature stayed with her. At the age of 23, she went to Africa for the first time to realize her dream. Though she never went to university, she learnt much about animals from books. With help from scientist Louis Leakey, Jane began studying chimpanzees (黑猩猩) in Gombe forest. Her study method was different from that of other scientists — she gave the chimpanzees names like David Greybeard and Flo, treating them as individuals (个体). For months, the chimpanzees ran away when they saw her. But Jane stayed patient, watching from a distance every day. Jane's patience brought amazing discoveries. She discovered that humans aren't the only animals who use tools. She saw David Greybeard use a grass stem to catch termites (白蚁) — the first proof that animals could make and use tools. She also discovered that chimpanzees feel emotions and have families, having seen them hug when sad, hold hands, or have their mothers teach them to find food. Later Jane realized that studying animals wasn't enough to protect them. She saw forests getting smaller and chimpanzees becoming fewer. So she started traveling worldwide, speaking to governments, schools, and communities. She told everyone that we must protect forests and the animals living in them. In 1991, Jane created Roots & Shoots to help young people make a difference. Students in this program clean up parks, plant trees, and help animals in their communities. One group in Tanzania built a safe place for birds. Another in Canada raised money to protect bear habitats (栖息地). Though Jane passed away recently, her work continues. She taught us that every person — including you and me — can help make our world better. As she often said, “Every day, each of us can make a difference.” 1.  When did Jane go to Africa for the first time? _______________________________________________________________________ 2.  How was Jane's way of studying chimpanzees different from that of other scientists? _______________________________________________________________________ 3.  What were Jane's discoveries about chimpanzees? _______________________________________________________________________ 4.  What did Jane create in 1991? _______________________________________________________________________ 5. Why do people see Jane Goodall as a great scientist? Please list two reasons based on the passage. _______________________________________________________________________ 五、阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 The Chihuahuan Desert in West Texas is larger than any other desert in North America. The winters there are cool and summers are very hot. This area is also home to a mysterious phenomenon (现象) called the Marfa Lights. The Marfa Lights are bright lights that appear in the night sky all of a sudden and then fly to faraway places and disappear. They are about the size of basketballs and are often described as white, blue, yellow, red, or other colours. The lights sometimes even get close to people's houses. One woman who lived on a farm told the story of what she experienced one night. She was in bed and suddenly she saw the lights shining through her bedroom window. She watched them change colour for a few minutes. Finally, they went away. Pilots who used to train in the desert in the 1940s also reported that they once saw these mysterious lights. What causes this phenomenon? People have different opinions on this. A popular interpretation is the lights might have something to do with headlights from cars on the road nearby. Scientific research also suggests that some of the lights are caused by the refraction (折射) of light between layers (层) of air that have different temperatures. However, not all of them can be explained so easily. Anyway, people will continue to study the lights to find out where they come from. No matter what these lights really are, they are as mysterious today as when they first appeared. But it is certain that the mystery behind them will be solved one day. ( )1.
