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：____________________________________。

A young girl sits at her desk, reviewing her homework for the evening. English: Read three chapters and write a report. Math: Complete 30 problems. Science: Do a worksheet, front and back. French: (A) Study new words for tomorrow’s test. It’s going to be a long night.
This happens to students in America. Now it’s time to start a homework revolution(变革).
Do students in the United States receive too much homework? According to the National Education Association, a student should be assigned (布置) no more than 10 minutes per grade level per night. For example, a first grader should only have 10 minutes of homework, a (B)  grader, 20 minutes, and so on. This means that a student in my grade—seventh—should have no more than 70 minutes of work (C) each night. Yet this is often doubled, sometimes even worse!
It’s no good giving students too much homework. According to research, kids are developing more illness at school, such as stomachaches, headaches and sleep problems than before.

Some people have different ideas, saying that homework prepares kids for doing better in high school, better in college, and (F) 今后找到更好的工作. But too much homework is sapping students’ strength, curiosity（削弱学生的个性和好奇心), and most importantly, their love of learning, is that really what teachers and parents want?
