boomer。婴儿潮（baby boom）这个词首次出现，主要是指,美国,第二次世界大战后“4664”现象-从1946年至1964年，这间婴儿潮人口高达7800万人。在世界上大多数国家都有此现象。在,日本,，称呼此时期出生人为“,团块世代,”団块世代。新中国成立后共出现过三次婴儿潮，值得注意是：当前人口众多“80后”一代也已长大，陆续成家立业。在二十一世纪前，中国将迎来新一轮“婴儿潮”。以这类推，每次,“婴儿潮”平均都会有20-30年周期。,38/42,撒哈拉沙漠(英文名为：Sahara Desert)世界上阳光最多地方，也是世界上最大和自然条件最为严酷沙漠。,撒哈拉沙漠是世界最大沙漠，几乎占满非洲北部全部。东西约长4,800公里(3,000哩)，南北在1,3001,900公里(8001,200哩)之间，总面积约8,600,000平方公里(3,320,000平方哩)。撒哈拉沙漠西濒大西洋，北临阿特拉斯山脉和地中海，东为红海，南为萨赫勒一个半沙漠乾草原过渡区。撒哈拉沙漠是世界上除,南极洲,之外最大,荒漠,，位于,非洲,北部，气候条件极其恶劣，是地球上最不适合生物生长地方之一。,阿拉伯语,撒哈拉意即“大荒漠”。,39/42,40/42,1.世界最严寒之极 南极洲年平均气温在28，大陆内部年平均气温在4060，,最低气温达89.6,2.暴风雪最强之地 南极沿海地域年平均风速为1718米/秒，阵风可达4050米/秒。最大风,速到达100米/秒，被喻为“世界风极”，“风暴杀手”。,3.最干旱大陆 南极大陆年平均降水量为55毫米，伴随大陆纬度增加降水量显著降低，大陆,中部地域年降水量仅有5毫米。在南极点附近，年降水量近于零，比非洲撒哈,拉大沙漠降水量还稀少。所以，南极是世界上最干旱地域。其主要原因是固,态冰雪降落在大陆后形成巨大冰盖，加之极端严寒气候和极少日照量，,冰盖累积量还略大于消融量，形成干燥“白色沙漠”。,4.最荒凉孤寂大陆 南极大陆是世界上至今唯一没有常住居民大陆。只有一些南极考查国家科学考查人员短期在南极工作，每年约人左右。,41/42,42/42,
