Mae JemisonImagine you are lying on your back, strapped into a chair, with your knees bent in front ofyou. You feel your heart beating with excitement as you hear a voice on the earphone inside your helmet counting down slowly,” Three, two, one,” Then, beneath you, a deep rumble start as rocket fuel ignites in the huge engines. You① feel a lurch as the docking mechanisms let go, and your rocket begins to rise. This is the moment Mae Jemison has been waiting and working for since 1987. The firstAfrican-American female astronaut-in-training at the National Aeronautics and Space②Administration (NASA) , Jemison is scheduled to “fly” in September 1992. She is to serve as a specialist on Spacelab—J, a joint Japanese—American research project.Mae Jemison was thirty-three when she was selected for NASA’s astronaut training program. Astronaut candidates must have science degree. They must be fit and healthy with normal blood pressure and good eyesight. They must stand between five feet and six feet four inches tall. They must complete a one-year training program that includes water-survival lessons and weightless walks in a huge antigravity tank. On the 1991 mission, astronaut Jemison says that her “responsibility are to be familiar with the shuttle and how it operates, to do the experiments once you get③ into orbit, to help launch the payloads or satellites, and also to do extra-vehicular activities, or space walks.”How did Mae Jemison grow up to become such a special person? Science —especially astronomy—fascinated her from childhood.She also had a strong desire to help other people. Born in Alabama, but raised in Chicago,she studied chemical engineering and African—American culture and history at Stanford University. To help others, she decided to become a doctor. While still a medical student, she went to Cuba and Kenya on study trips, then worked in④a refugee camp in Thailand. She spent three years in West Africa as a doctor with the Peace Corps. When Dr. Jemison finally returned to the United States, she settled in California to practice medicine. And it was then that she decided to reach for the stars.Mae Jemison’s first application to NASA was not successful. Then, in 1986, the⑤Challenger space shuttle exploded, killing all aboard . NASA did not take in any new astronauts for about a year. When it finally reopened its application process, Mae Jemison was ready, and so was NASA. After being selected as a minority astronaut, Mae Jemison received a good deal of attention from newspaper and television. She explained to reporters that the space program and other fields in high technology offer promising careers for African-Americans and other minorities who study hard⑥ and make the most of their opportunities .1.The first paragraph is about ______.A.how excited Mae Jemison was when she became an astronautB. how Mae Jemisonbecame an astronautC.how the people usually feel when the rocket they take begins to riseD.what Mae Jemison did after she was able to fly a rocket2.Which of the following statements is true?A.Mae Jemison had a strong desire to become famous.B.Mae Jemison was brought up in Alabama.C.Mae Jemison studied astronomy at Stanford University.D.Mae Jemison studied medicine.3.When did the Challenger space shuttle explode? A. Before Mae Jemison became a doctor.B.Shortly after Mae Jemison graduated from Stanford University.C.About a year before Mae Jemison was selected as an astronaut.D.About a year after Mae Jemison became famous all over the world.4.Mae Jemison believed that _______.A.men and women were not equalB.women were better paid than men wereC.American blacks were unable to find satisfactory jobs no matter how hard they studiedD.American blacks were able to find satisfactory jobs if they studied hard and made gooduse of their chance5.What is the attitude of the writer towards Mae Jemison’s achievements?A.JealousB.UpsetC. NegativeD. PositiveNotes:①lurch v. : To roll or pitch suddenly or erratically. 突然倾斜,突然地或者无规则地倾斜或坠落。
