在探究植物光合作用、呼吸作用和蒸腾作用活动中，某同学设计以下探究方案，请你用所学知识进行分析．
（1）甲图中将植物罩上塑料袋，放在光下3-4小时后，将塑料袋中气体通过①号试管收集后取出试管，将一支带火星的木条伸进①号试管内，结果带火星木条复燃了，由此得出的结论是______．
（2）乙图中将植物罩上塑料袋，放在光下3-4小时后，挤压塑料袋使气体通入2号试管，发现澄清石灰水变浑浊．由此得出结论是______．
（3）甲图和乙图现象的出现有一个重要的条件是______．
（4）甲图的实验过程中，塑料袋内壁上出现水珠，其来源主要是植物的______作用，该作用能促进植物对______的吸收，散失水分的具体结构是______．
（1）甲装置用的是透明塑料袋，放在光下3-4小时后，塑料袋内会由于植物的光合作用而积聚了大量的氧气；因此将塑料袋中气体通过①号试管收集后取出试管，将一支带火星的木条伸进①号试管内，木条会迅速复燃．由此得出的结论是 植物的光合作用产生氧气．
（2）将乙装置放在黑暗处，装置中的植物只进行呼吸作用，不进行光合作用，因此一段时间后塑料袋内会积聚大量的二氧化碳气体，这些气体会使②号试管中的澄清石灰水变浑浊．（3）甲、乙两装置，一个用透明塑料袋，一个用黑色塑料袋，这是以光为变量形成一组对照实验，目的是探究光合作用的条件是光．
（4）水分以气体状态通过叶片表皮上的气孔从植物体内散失到植物体外的过程叫做蒸腾作用；在实验过程中甲装置中的植物通过蒸腾作用散失的水蒸气会凝结在塑料袋的内壁上；因此在实验过程中塑料袋内壁上会出现水珠；这些水分是植物的根从土壤中吸收的，并通过茎内木质部里的导管自下往上运输来的．
故答案为：（1）植物的光合作用产生氧气（或氧气是光合作用的产物）
（2）植物的呼吸作用产生二氧化碳 （或二氧化碳是呼吸作用的产物）
（3）甲图透明的塑料袋，乙图是黑色（不透明）的塑料袋
（4）蒸腾；水（或水分）；气孔
ople believe everything or almost everything they read in newspapers or hear on radio. A few years ago I __36__ a story about a husband and wife who made a __37__ mistake. They had gone shopping and had taken their small baby __38__ with them. After they had finished their shopping, they returned to their car to go home. __39__they reached their car, they put the baby in the plastic baby carrier that __40__ rode in for safety. The couple then __41__ in their car towards home. After they had driven a few miles, they __42__the back seat to see how the baby was. To their surprise, the baby was not there. According to the __43__, the couple had put the plastic seat and the baby on the top of the car but had __44__ to put him inside the car. They had driven away with the baby on the top of the car. 
aby had fallen from the top of the car but had been __48__ by his plastic seat. The __49__couple took their baby home and were always careful after that.
