(2)D
【解析】(1)德國科學家魏格納在偶然翻閱世界地圖時發(fā)現(xiàn):大西洋的兩岸﹣﹣歐洲和非洲的西海岸遙對南北美洲的東海岸,輪廓非常相似,這邊大陸的凸出部分正好能和另一邊大陸的凹進部分湊合起來,他堅信這不是巧合,便順著這條思路研究下去,后來提出了大陸漂移假說,選項ABD敘述正確,不符合題意。故選:C。(2)圖中海牛生活在熱帶淺海環(huán)境中,鴕鳥生活在陸地上,且不會飛,根據(jù)它們分布在大洋兩岸的現(xiàn)象,可以說明很久以前兩塊大陸連在一起。故選:D。

Who is the greatest teacher in Chinese history? Many people would think of Confucius(孔子), whose birthday was September 28. Although he lived over 2, 000 years ago, people still remember and respect him for his contribution(貢獻) to the education today.
Confucius lived in the Kingdom of Lu, which lies in Shandong Province. He lived during the Spring and Autumn Period. He had a hard childhood. His father died when he was only 3.
