Robinson was a sea - loving man. Once, he went on a sea journey. Unluckily, the ship hit a rock and sank. Robinson was the only one who survived (幸存). He swam to a lonely island. At first, he had nothing. But he didn't give up. He used his cleverness and courage to build a house, make tools, and grow food.
He also saved a native man from the hands of cannibals (食人族). He named this man Friday. Friday became Robinson's good friend and helper. They lived together on the island for many years.
Finally, after 28 years, Robinson was saved by a passing ship and returned to England. His story became very famous. People were amazed by his strong will and survival skills. The book *Robinson Crusoe* is not only an exciting adventure story but also gives us a lot of inspiration (启示). It tells us that no matter how difficult the situation is, we should never lose hope and always try our best to overcome (克服) difficulties.

②Cl2与KI反应的化学方程式　　 　，其中　 　是氧化剂．
③已知Cl2可与H2O反应生成两种酸，其化学反应方程式为：Cl2+H2O═HCl+HClO，则Cl2与NaOH溶液反应的化学反应方程式为 　
【答案】铁；Cl2＞Br2＞I2；Cl2+2KI═2KCl+I2；氯气；2NaOH+Cl2═NaCl+NaClO+H2O
【解析】还原反应及其应用。
（1）由于铁元素的化合价有0→+2，而铜元素由+2→0，因此铁是还原剂；
（2）①由题意可知，活动性较强的非金属可把活动性较弱的非金属从其盐溶液中置换出来，由Cl2+2NaBr=2NaCl+Br2；Br2+2KI=2KBr+I2可以判断出Cl2、I2、Br2活动性由强到弱的顺序是Cl2＞Br2＞I2．
②由题意可知，Cl2能把I2从其盐溶液中置换出来，反应的方程式是：Cl2+2KI═2KCl+I2．由于氯元素的化合价有0→﹣1，而碘元素由﹣1→0，因此氯气是氧化剂；
