在人类即将跨入新世纪之际,不同的技术岗位上活跃着不同肤色的科学技术人员与行家里手。但是,20世纪初期,在白人至高无上的美国,黑人的社会地位极低,更不用说参与技术性工作了。就是在这种社会背景下,依然有一些自强不息的黑人发奋图强,努力奋斗,创下了可歌可泣的业绩。贝丝·考莉曼(Bessie.Coleman)就是其中的杰出代表。 As human beings are about to enter the new century, scientific and technological personnel and experts who are active in different technical positions are active in different colors. However, in the early twentieth century, in the supremacy of the white Americans, the blacks had very low social status, let alone engaged in technical work. It is in this social context that there are still some self-improvement black people working hard and making concerted efforts. Bessie.Coleman is one of the outstanding representatives.
