50、償了這一缺陷，鴕鳥每小時(shí)可以奔跑 70 公里。鴕鳥的腿長(zhǎng)而健壯，它的雙翼卻很小。由于它們象駱駝那樣，可以在熱帶沙漠中奔跑，所以它們被稱做“鴕鳥”。鴕鳥的翅膀確實(shí)小，但它跑得快，快得如同飛起來一般。有一句諺語叫“一只把頭埋在沙子里的傻鴕鳥”， 來描述鴕鳥的傻乎勁， 但鴕鳥真的那么傻嗎？來看看這篇文章吧。 Thelargestbirdthatcannotflyalsohappenstobethelargestlivingbirdintheworld.ThisisthehugeNorthAfricanostrich.Whenthemale,orcock,isfullygrown,hereachesa
