As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger.
Scientists have found out that radiation (辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage done by radiation won’t be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really helpful medicine has been.
Space junk (垃圾) is also thought a great danger to spacemen. It’s reported that there are 9,000 man-made (人造的) things flying in space. About 30% of these are man-made satellites (卫星), 10% are spaceships, and the rest are space junk. An explosion (爆炸) in 1996 made a cloud of 30,0000 fragments, each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and reporting any possible danger all the time. They are working on helpful ways to do with space junk.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.

第1章 化学反应与能量转化
第4节 金属的腐蚀与防护(基础课)
1.通过讨论钢铁腐蚀的现象,认识金属腐蚀的本质,能用电化学腐蚀的原理解释金属腐蚀的现象。
2.通过讨论日常生活中金属腐蚀的危害,能选择并设计防腐措施。
学习任务
1.铁制品锈蚀的过程,实际上是铁与空气中的氧气、水蒸气等发生化学反应的过程。
2.铝与氧气反应生成的致密的氧化铝薄膜,能覆盖铝的表面,从而保护内部的铝不再与氧气反应;而铁与氧气、水等反应生成的铁锈(主要成分是Fe2O3·xH2O)很疏松,不能阻碍内部的铁继续与氧气、水等反应,因此铁制品可以全部锈蚀。
