最难忘的事：1．去中国科学院院士、中南大学校长黄伯云爷爷的国家级实验室参观，看到了“神六”上用的航天材料。因为每班只选15个人，没想到，竟然选中了我，这让我很兴奋。星期天下午，我们就高高兴兴地到了学校的大实验室门口。哇!想不到里面人山人海，好像到了迪斯尼乐园 The most memorable thing: 1. To the Chinese Academy of Sciences, President of Central South University, Huang Boyun grandfather's visit to the national laboratory, saw the “Shenzhou VI” on the use of aerospace materials. Because only 15 people per class, I did not expect, actually selected me, which makes me very excited. Sunday afternoon, we happily went to the school's large laboratory door. Wow, I can not think of the crowds, it seems to Disneyland
