看了有关中国和美国基础教育水平高低比较的帖子，颇有感概。根据我的经验，我知道有很多美国小学一年级的学生能够顺利地回答以下10个问题：
1）蜘蛛属于昆虫吗？什么是昆虫最主要的特征？
2）蝴蝶生命周期中的几个主要阶段是什么？
3）你观察过Salmon从鱼卵到成年的生长过程吗？
4）你能解释什么是Mammal，Fish，Bird吗？
5）你知道Reptiles包含哪几种动物吗？
6）什么是star?什么是planet?
7) 你知道什么是Saturn ring吗？有没有通过天文望远镜观察过？
8）你能从夜空 |

英国苏格兰的圣安德鲁斯大学(St Andrews University)海洋哺乳生物研究机构(

澳大利亚也有研究发现，公海豚为了展现权威，会压在其他同性身上，造成血腥斗

美国海豚通讯计划(the Dolphin Communication Project)的海洋学者格雷格(

通群众当中的影响力，也算得上是纪录片的佼佼者。不过，大致由原班人马于六年后（

尽管这部片子展示了更为广泛的生物种类和时间跨度。毫无疑问，不正确地囊括了翼龙
鱼龙蛇颈龙等等的恐龙大家族，是人类影视当中一个经久不衰的主题，上个世纪三十年
