2014年5月，我国科学家成功试验了世界上第三个封闭试验系统﹣﹣“月宫一号”，“月宫一号”内有动物、植物等十几种生物，它是能与地球媲美的“微型生物圈”，使人类在月球等外太空长期生存成为可能．

在“月宫一号”，人、动物等呼吸作用产生的二氧化碳可供给植物进行光合作用；植物产生的　　气体可供给其他生物进行呼吸作用，植物主要通过　　（填器官名称）的蒸腾作用产生水，经处理后可用于生活用水．

答案

氧气；叶．

题目分析：植物的光合作用是在叶绿体里利用光能把二氧化碳和水合成有机物，释放氧气，同时把光能转变成化学能储存在合成的有机物中的过程；呼吸作用指的是细胞内有机物在氧的参与下被分解成二氧化碳和水，同时释放能量的过程．蒸腾作用是指植物体内的水分通过叶片的气孔以水蒸气的形式散发到大气中去的一个过程，可见叶片是蒸腾作用的主要部位，其次叶柄和幼嫩的茎也能蒸腾少量的水分，也能进行一定的蒸腾作用，因此植物蒸腾作用的主要器官是叶片．

所以人、动物等呼吸作用产生的二氧化碳可供给植物进行光合作用；植物产生的氧气气体可供给其他生物进行呼吸作用，植物主要通过叶）的蒸腾作用产生水，经处理后可用于生活用水．

The rain was coming down heavily and I was going to be late for an important conference. Dressing up quickly, I called for a taxi,        that it would be faster than the subway.
It wasn't.

As the       came out, I wanted to take them back. The wrongness of my       to the driver shocked me. Why did I let out the shout?
The driver      me and we continued the journey. Eventually I got out of the taxi and
    to the office. As I ran, I understood that, though it wasn't my duty to take the time to help others, I shouldn't have        the driver's stopping. I should have been able to see beyond my impatience to notice what was most inerrant (不会错的). Whenever I think of this incident, this is my   : I am not a       self-centered person, but I still feel
of being self-centered. Living a busy life in a fast-paced big city, do we still need to stop to help those who are in need of help?
