Alice was very worried about her dad. For some time now she had noticed he was 1 his hair. One day, she asked him, “Daddy, every day you have less hair.2 is that?” Her father smiled and said, “It's the hair thief. He visits my head during the night when I'm 3. One by one he 4 out my hair, as much as he likes.”

    This worried Alice but she was 5 to help her father. That very night she stayed 6 as long as she could. When she was 7 her dad and mom had fallen asleep, she took a hammer and went straight to their bedroom. She walked carefully in order not to make any 8. She didn't want the hair thief to hear her. Then she began carefully 9 her father's head. When she arrived at her father's side, she began looking at his head,10to catch the hair thief as soon as he appeared. Before long, she saw a shadow on it and 11 all her strength, she swung the hammer down.

    Thwack! Her father 12a loud cry. The lump(肿块) on his head was big and growing.13 with shock, he turned the light on and saw Alice waving her hammer in the 14 with her hands. “Daddy, I 15 got him. I thought I 16 him, but it looks like he escaped!” said Alice. At the same time, the mother woke up. She 17laughing when she knew what had happened.

    So Alice's father had to 18to her that the hair thief didn't exist, and that losing hair is something that just happens 19 to most daddies. And Alice still worried about her daddy, but she no longer waited for the hair thief.20 , she bought her daddy a very nice sleeping hat.

他们俩没有什么共同之处，可是他们彼此相处得很融洽。

关于反应：2Mg+CO₂C+2MgO，以下说法错误的是（　　）

实验一：采用差速离心法将一份叶片制备叶绿体（假设制备叶绿体时不考虑叶绿体的破坏），均分为4组，分别置于不同浓度的KHCO₃溶液中，在适宜光照、20℃恒温条件下，分别用氧电极测定其O₂释放速率．

实验二：将另一份叶片切成约1.0mm×1.0mm小块（假设小块叶片的大小、形状不影响光合速率，光合速率只与叶绿体数量有关．），均分为4组，其他步骤与“实验一”相同．

实验结果如图，请据图回答下列问题：
