She once said to her father, “That isn’t my only dream. I want to know more 6 things.” Her father answered, “Don’t worry! I 7 to help you all the time.”
Mae studied science and African history in 8 . After she finished her study here, she became a doctor and went to work in Africa to help the 9 . She often treated them for free, so people there thanked her a lot.
When Mae went back home in America, she still 10 to visit space. She applied (申请) twice and 11 was picked to fly in space. Along with six others, Mae set out 12 the spaceship, and soon they were in space. They needed to stay there to help and then flew back to the earth after weeks. The 13 was challenging (有挑战性的). Mae knew the space travel was not easy and she had to 14 to keep her body strong for another visit to space.
Mae was now the first African-American spacewoman after 15 many difficulties. Her story sets an example for many girls to go for their dreams.

请结合两个电极上的电极反应式说明用镉氧循环法实现过度充电保护的原理： 。
五、解答题
20．实验小组探究铝片做电极材料时的原电池反应，设计下表中装置进行实验并记录。
【实验1】
装置 实验现象
左侧装置电流计指针向右偏转，灯泡亮右侧装置电流计指针向右偏转，镁条、铝条表面产生无色气泡
（1）实验1中，电解质溶液为盐酸，镁条做原电池的 极。


化学方程式:Al2O3＋6HCl===2AlCl3＋3H2O、2Al＋6HCl===2AlCl3＋3H2↑
(2)铝、氧化铝与NaOH溶液反应
化学方程式:Al2O3＋2NaOH＋3H2O===2Na[Al(OH)4]、2Al＋2NaOH＋6H2O===2Na[Al(OH)4]＋3H2↑
(3)两性氧化物
既能与酸反应生成盐和水，又能与碱反应生成盐和水的氧化物，如：Al2O3。
3．氢氧化铝
Al(OH)3是不溶于水的两性氢氧化物(既能和酸反应生成盐和水，又能和碱反应生成盐和水的氢氧化物叫做两性氢氧化物)，既能与强酸反应：Al(OH)3＋3H＋===Al3＋＋3H2O，又能与强碱反应：Al(OH)3＋OH－===[Al(OH)4]－。
