蜜蜂是靠太阳来辨别方向的。在一天中,蜜蜂舞蹈的方向是随着时间不同而变化的。蜜蜂是依靠蜂、采蜜地点和太阳三个点来定位的。蜂是三角形的顶点,而顶点角的大小是由两条线来决定的:一条是从蜂到太阳,另一条是从蜂到采蜜地点的直线,这两条线所夹的角叫“太阳角”,是蜜蜂的“方向盘”。蜜蜂向左先飞半个小圈,又倒转过来向右再飞半个小圈,飞行路线就像个“8”字。可是,蜜蜂有时从上往下飞,有时从下朝上飞,而飞行直线同地面垂直线的夹角,相等于太阳角。蜜蜂正是从这种角度的大小来确定采蜜地点和方向的。
如果蜜蜂跳“8”字舞时,头朝上直飞,太阳角是零度,意思是说:“朝太阳方向飞去,就是采蜜的方向。”
如果蜜蜂跳“8”字舞时,头朝地直飞,太阳角是°,意思是说:“背太阳方向飞去,就是采蜜的地方。”
如果蜜蜂跳“8”字舞时,飞行直线同地面垂直线的左面夹角是15°角,意思是说:“向左太阳角60°方向飞去,就是采蜜的地方。”
有趣的是,不同地方的蜜蜂,“舞蹈语言”也不同。奥地利的蜜蜂跳“8”字舞,而意大利的蜜蜂还会跳圆形舞和一种弯弯的“镰刀形舞”。
如果碰上坏天气,阴云密布,没有太阳,也看不见空中的极化光,蜜蜂就失去了辨别方向的能力。

英语作文:我最爱的人(父母,老师等)
Father's LoveMother's love wins people's praises for its selflessness. In fact, father's love is as great as that. They bury their love in the deep bottom of their hearts and will never show it. My father is of this kind. I remembered once I felt ill. Mother wasn't at home at that moment. Father acted as a father and as a mother as well. When he came home from work, he would cook dinner for me first. The way he fed me made me think of my kind and tender mother. His eyes were full of love and expectation. I did feel a father's love at that time.人们经常赞美母爱的无私。
其实,父爱同样是伟大的。
他们把爱深藏在内心,而不轻易显露。
我的父亲就是这样的。
有一次,我病了,妈妈又不在家,爸爸又当爸又当妈。
他下班回家的第一件事就是给我做晚饭。
他喂我吃饭的样子让我想起了善良温柔的妈妈。
他的眼中布满着爱怜和期待。
彼时彼刻,我真的感受到了父爱。
