Unit 17,A cuckoo in the nest,lead-in,动物界的十大坏妈妈:布谷鸟 cuckoo 布谷鸟准备产蛋了，但它却不会自己筑巢,它会来到像那些比它小的鸟类的巢中，移走原来的那窝蛋中的一个，用自己的蛋来取而代之。相对于它的体形来说，它的蛋是偏小的，而且蛋上的斑纹同它混入的其他鸟的蛋也非常相似，所以不易被分辨出来。如果不是这样，它的蛋肯定会被扔出去。 布谷鸟的鸟蛋比其他鸟蛋早孵化。幼鸟出来后，会立刻把其他的蛋扔出巢外。它之所以这样做， 是因为它不久就会长得很大，需要吃光养母所能找到的全部食物。 一只布谷鸟的幼鸟正在由它的养母-一只比它小得多的刺嘴莺喂食。它需要的食物相当于3-4只其养母亲生的幼鸟本来需要进食的总量。 趁其他鸟没看见时，布谷鸟在它们的巢中产蛋。它必须非常迅速地做完这件事。它的蛋有着特别厚的外壳，这样在落入巢中时就不会碎掉了。,lesson 33,Lets learn some new words and expressions: cuckoo n. 杜鹃，布谷鸟 nest n. 鸟窝，巢 engineer n. 工程师 enthusiastic adj. 很感兴趣的 birdwatcher n. 观鸟者 appear v. 出现 install v. 安装 webcam n. 网络摄像机 invite v. 邀请 log on v. + adv. 登录 enthusiastically adv.
