      A seabird named Lydia recently made a 26-day nonstop(不间断的)journey of about 2,500 mi­les, just to search for food for her baby. She is fitted with a satellite tracking device (卫星跟踪仪). Her trip started on Oct. 18 from Christmas Island in the Indian Ocean. The trip is known as the lon­gest nonstop journey by one of these endangered seabirds.

      Before that, this kind of birds was known only to fly a few hundred miles from where they live, staying away for just a few days at a time. They usually fly over the sea.

      The scientists feel it strange that Lydia made such a long, nonstop journey and flew overland. So the above facts raise some serious questions about efforts to stop the decline(减少)of the birds. The number of the birds has fallen by 10 percent over the past 20 years.

Besides, the scientists are surprised that she was away from her baby for such a long time. They wonder why she needed to go that far. Maybe it shows that fish resources (资源)around Christmas Island are not large enough now. That might explain the slow decline of the bird 一 sea pollution(污染) is serious.

鱼的生长与水中溶氧量密切相关，鱼缸中每升水的溶氧量低于3mg时，鱼就会死亡．过氧化钙（CaO₂）是一种化学增氧剂，其反应原理是2CaO₂+2H₂O=2Ca（OH）2+O₂↑，将14.4g的过氧化钙加和装有1000L水中的鱼缸中．（已知：水的密度为1g/cm³，1L=1000ml=1000cm³）

（1）计算生成氧气的氢氧化钙的质量分别是多少？

（2）通过计算判断：

①生成的氧气完全溶于水时，鱼缸中的溶氧量是否达到最低要求？

②已知20℃时，氢氧化钙的溶解度是0.17g，鱼缸中的氢氧化钙溶液是否饱和？

    黔无驴，有好事者船载以入。至则无可用，放之山下。虎见之，庞然大物也，以为神。蔽林间窥之，稍出近之，慭慭然，莫相知。

    他日，驴一鸣，虎大骇，远遁，以为且噬己也，甚恐。然往来视之，觉无异能者。益习其声，又近出前后，终不敢搏。稍近，益狎，荡倚冲冒，驴不胜怒，蹄之。虎因喜，计之曰：“技止此耳！”因跳踉大阚，断其喉，尽其肉，乃去。
