    Dear Earthmen(地球人)，
    I enjoy my stay on your interesting planet(星球).
    I think I know the life on Earth now and I would like to tell you my ideas.
    First of all you live in boxes. Every morning you leave your boxes and get into smaller boxes on wheels(轮子). All these small boxes run around and around, and finally stop to rest. You leave these boxes on wheels and go to very large tall boxes.
    After resting all day, you get back in your little boxes. There you sit and look at very small glowing boxes with moving pictures in them.
    There is only one thing I don’t know. Some angry boys fought for a little round (圆的) ball. Everyone shouted(大声喊) but they kept fighting. They were angry, because they had to stay in boxes all day, I think.
    Thank you for this chance(机会) to get to know you.
    Yours,
    The man from Mars(火星)

    阅读下面有关“光合作用的发现”的资料，重温科学家的研究过程，回答下列问题：
    资料一：1771年英国人普利斯特利发现，将薄荷枝条和燃烧的蜡烛放在一个密封的钟罩内，蜡烛不易熄灭；将小鼠与绿色植物放在同一钟罩内，小鼠也不易窒息死亡。
    资料二：1864年德国的萨克斯把一株盆栽植物放在黑暗处一昼夜，然后把其中一个叶片一半曝光，一半遮光，过一段时间后用碘蒸气处理叶片，发现遮光那一半没有发生颜色的变化，曝光的那一面则成深蓝色。
    资料三：1880年德国恩吉尔曼把载有水绵和好氧细菌的临时装片放在没有氧气的黑暗环境里，然后用极细的光束照射水绵。通过显微镜观察发现好氧细菌只集中在叶绿体照光部位附近。如果上述临时装片完全暴露在光下，好氧细菌则集中在叶绿体所有受光部位周围。
    （1）普利斯特利的实验都是在_____________条件下进行的，这时钟罩内的小白鼠不易窒息死亡的原因是__________________________________________________。
    （2）萨克斯将一个叶片一半遮光，一半曝光的目的是________________。]
    （3）由恩吉尔曼的实验可得出的结论是：光合作用的场所是______________。
    （4）绿色植物的光合作用对于维持生物圈中的_____________平衡起着重要作用，因而绿色植物被称为“空气净化器”。
    （5）根据科学家研究发现的光合作用原理，在农业生产中可以采取何种有效措施以提高农作物的产量？答：____________________________________。
