小芳用相同溶质质量分数的NaOH溶液、CuSO4溶液和葡萄糖溶液进行葡萄糖与新制的Cu(OH)2反应条件的探究：
①在2mL NaOH溶液中滴加3滴CuSO4溶液，有蓝色沉淀_____________ (填化学式)生成，再加入2mL葡萄糖溶液，加热到沸腾，出现了红色沉淀。
②在2mL NaOH溶液中滴加3滴CuSO4溶液，有蓝色沉淀生成，再加入2mL葡萄糖溶液，没有出现红色沉淀。这说明葡萄糖与新制的Cu(OH)2反应的条件之一是_____________ 。
③在2mLCuSO4溶液中滴加3滴NaOH溶液，再加入2mL葡萄糖溶液，加热到沸腾，没有出现红色沉淀。这说明葡萄糖与新制的Cu(OH)2反应的条件之二是：________________。
①Cu(OH)2；
②加热至沸腾(或“加热”)；
③在碱性溶液中进行(或NaOH溶液过量或CuSO4溶液少、NaOH溶液多)。

| When I was a teenager growing up in France, I wanted to leave school and have my own life. The only way I could do this was to work in the local paper factory in my town, or get married. I was very nervous then I told my 1 I wanted to leave school. I thought he would say, " 2 ! You are going to college." I was very 3 when he said, "OK. Let's go to the paper factory." Two days later, he took me to the factory. I imagined everyone to be friends 4 together and having fun. I even imagined there would be music and singing. I guess I had watched too many movies as a teenager. When we 5 the factory gate, my father spoke to the guard and one minute later we were 6 . I walked around the factory looking at the building, the workers, and listening to the noise. It was 7 . I ran back to my father and said, "I want to go home." He asked me,"What do you think of the factory?" "Too bad," I answered. "And marriage is even 8 !" he said. I went back to school the next day thinking about studying hard 9 I could get into a good college. I 10 studying English, so I decided to major in languages at college. Thanks to my father and our trip to the paper factory, I now work at the United Nations and my father is very proud of me. I married a very good man and my life is much better than it would have been working in the factory! | ||||
