The manufacture of plastics requires a large quantity of heavy machines as well as knowledge of science. Today the greater part of plastics is manufactured by the world's great oil refineries and chemical works. Chemical works are factories which produce chemicals—a manmade liquids, gases and solid materials. The refineries and chemical works produce many different kinds of raw plastics, which are then taken to the tens of thousands of factories which made plastic products. Machines for making plastic objects are very different from those used for manufacturing articles of wood or metal or other natural materials. For raw plastics must first be softened by heat and then pressed into moulds. It is the moulds which give plastic objects their shapes. These moulds can be of any shape or size. And the same mould can be used over and over again. In fact one mould can produce many thousands of articles before it wears out. This is one of the reasons why plastic things are so cheap.

国际空间站的设计初衷是作为一个向其他星球发送航天器的平台。不过，这一使命后来转变成了一个绕地球运行的实验室，对人类和其他生物体在太空环境下的表现进行试验，希望藉此对基本生命功能有更多的了解、发现新的医疗方法。在很多试验中，需要有人类进行或参与。

不同的人对退休持不同的态度。有些人认为退休后可以好好享受晚年的生活。但真的退下来了，他们则有点失望。看到自己就要被抛到废物堆里，他们不甘认命，设法另找事干来发挥自己的余热，以继续得到收入。另一些人则对一生中这样一个重大变动早有准备。他们一生为工作操劳，现在筋疲力尽了，渴望退休后能放松拉紧的弦，好好休息。由于不再需要每天早晨去赶公共汽车了，不再要为晋级忧虑，就可以有足够的时间去追求童年时的梦想，如写写书、画画图、种种花、周游各地。总的说来，女的要比男的欢迎退休。她们退休后完全过一种家庭生活，没有像男的一样感到可怕。

我们大家生活在同一个星球上，因此我们要共同对付人类生存与发展面临的挑战。生态环境恶化，贫困失业，人口膨胀，疾病流行，毒品泛滥，国际犯罪活动猖獗，以及妇女儿童权益得不到保障等等，都是事关人类生存与发展的全球性问题。发达国家对其在工业化，现代化过程中造成的生态环境恶化是欠了债的，理所当然地应对环境保护做出更大的贡献。这些全球性问题的逐步解决，不仅要靠各国自身的努力，还需要国际上的相互配合和密切合作。
