前面一个该学校老师参加空间物理研究的例子,再下来是这两句子：  This instance shows（or illustrate, demonstrate） the great significance of XX to our human kind and the great contribution your school have made to our world. It is just this instance that enable me to think of XX discipline as compelling enough to devote my entire life to.  请高人指教，偶心里对这两句话没谱！！！多谢了！
