八年级英语冀教版下Book4 Unit2 lesson11 Amazing Plants

维纳斯捕蝇草面包树俗名面包树、面包果，原产于马来半岛以及波利尼亚，如今因人类传播而分布玻里尼西亚，印度南部，加勒比地区等热带地区。果实可食用，风味类似面包，因此而得名。一般高10多米，最高可达40多米。树干粗壮，枝叶茂盛，叶大而美，一叶三色。雌雄同株，雌花丛集成球形，雄花集成穗状。在它的枝条上、树干上直到根部，都能结果，结果的时间一年内有9个月。每个果实是由一个花序形成的聚花果，果肉充实，味道香甜，营养丰富，含有大量的淀粉和丰富的维生素A和B及少量的蛋白质和脂肪。人们从树上摘下成熟的面包果，放在火上烘烤到黄色时，就可食用。面包树在非洲生长着一种会发光的奇树，又名照明树、魔树。在白天看上去与一般普通的树没有什么两样，可是到了夜晚，从树干到树枝都发出明亮的荧光，把树的周围照得雪亮，远远望去犹如“火树银花”，非常好看。夜晚，当地居民可以在树下看书读报，甚至能做精细的针线活。魔树的发光奥秘在哪里呢？科学家经过研究发现，在树皮里含有大量的磷，当磷与氧接触时便会发出亮光。然而，树中这么多的磷是从哪里来的呢？这还有待于科学家去研究和探索，才能揭开这个谜。发光树Lesson11AmazingPlants
