She was dispatched to the southern Chinese island of Hainan to study how malaria threatened human health. Ancient Chinese texts inspired Tu Youyous search for her Nobel-prize

4、 winning medicine. Mission 523 pored over ancient books to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, over 240 000 compounds around the world had already been tested, without any success. Finally, the team found a brief reference to one substa

7、 mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. “As the head of the research group, I had the responsibility,” she explained to the Chinese media.

8、ace. This dream began to seem possible when high-flying rockets were built in the early 1900s. In 1903 a Russian teacher named Konstantin Tsiolkovsky figured out how to use rockets for space travel. His plan was the first one in rocket science to use correct scientific calculation. About 30 years la

9、ter, a U.S. scientist named Robert Goddard built the first rockets that could reach high altitudes. During World War II, German scientists built large rockets that could travel very far and carry dangerous explosives. After the war, scientists from Germany went to the United States and the Soviet Un

10、ion to help those countries build space rockets. These two countries were soon racing to get to space first. Each of these countries wanted to prove that it was stronger and more advanced than the other one. Both countries also had powerful bombs. People in the United States were worried when the So

11、viets were first to launch a space satellite, which was called Sputnik. The Soviets were also first to send a person into space. Yury Gagarin orbited the earth in the Vostok I spaceship in 1961.,The US government set a goal for its space program to be the first country to put a person on the Moon. T

12、he U.S. space program built a series of Apollo spaceship. These vehicles were powered by huge Saturn 5 rockets. In 1969 Apollo II took three men to the moon successfully. Nell Armstrong became the first person to walk on the Moon. The Soviets may have lost the race to fly people to the Moon, but the

13、y built the first space station in 1971. The United States also built a space station. The space stations allowed people to live and work in space. Then the Soviet Union and the United States cooperated to hook two spaceships together in space. This action ended the space race. Today a much larger s

14、pace station, built by several countries together, orbits Earth. Another new way to go to space is by space shuttle. A space shuttle, first made in the United States in 1981, looks like an airplane. Astronauts who fly spaceships have used shuttles to help put satellites into space.,二、圈划关键句,难以取舍?,以结果
