37、. withbiganimalslikehorses. 蚯蚓是改良土壤的能手。蚯蚓能使土壤形成团粒结构，这是农业上最好的土壤结构，系钙离子和腐殖质胶结土粒所形成的土团，遇水不易松散，抗压性较强，疏松多孔，透气性好。一般蚯蚓吞食有机物和泥土， 经过砂囊研磨、 体内消化酶和微生物的作用， 消化分解后合成钙盐，连同蚯蚓钙腺排出的碳酸钙可形成粘粒结构。这种团粒结构土壤具有很强的保水性胶质及水溶性养料，有利于植物生长。达尔文在 1881 年写道：“这种低等动物对地球历史起的重要作用，恐怕是其它任何一种动物所比不上的”。 Theearthwormisausefulanimal.Outoftheground

50、偿了这一缺陷，鸵鸟每小时可以奔跑 70 公里。鸵鸟的腿长而健壮，它的双翼却很小。由于它们象骆驼那样，可以在热带沙漠中奔跑，所以它们被称做“鸵鸟”。鸵鸟的翅膀确实小，但它跑得快，快得如同飞起来一般。有一句谚语叫“一只把头埋在沙子里的傻鸵鸟”， 来描述鸵鸟的傻乎劲， 但鸵鸟真的那么傻吗？来看看这篇文章吧。 Thelargestbirdthatcannotflyalsohappenstobethelargestlivingbirdintheworld.ThisisthehugeNorthAfricanostrich.Whenthemale,orcock,isfullygrown,hereachesa
