填充剂
填充剂（英文名称filler）又名填料、填加剂、填充物（additive；addition agent；stuffing bulking agent）。加入物料中可以改善物料性能，或能增容、增重，降低物料的成本的固体物质。通常不含水、中性、不与物料组分起不良作用的有机物、无机物、金属或非金属粉末等均可作为填充剂。常用的工业填充剂有高岭土、硅藻土、滑石粉、石墨、炭黑、氧化铝粉、玻璃粉、石棉粉、云母粉、石英粉、碳纤维、粉末状软木、金刚砂等。在化工生产的塑料加工、橡胶加工、纸张、涂料、农药、医药等产品中大量使用各种填充剂，不但改善了这些产品的性能，也大大降低了生产成本。

请阅读 Passage 2，完成第 26~30小题。Passage 2 The common cold is the world's most widespread illness， which is plague that flesh receives.The most widespread fallacy of all is that colds caused by cold.They are not， They are caused by viruses passing on from person to person.You catch a cold by coming into contact， directly or indirectly， with someone who already has one.If cold causes colds， it would be reasonable to expect the Eskimos to suffer from them forever.But they do not.And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.During the First World War soldiers who spent long periods in the trenches， cold and wet，showed no increased tendency to catch colds.In the Second World War prisoners at the notorious Auschwitz concentration camp， naked and starving， were astonished to find that they seldom had colds.At the Common Cold Research Unit in England， volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time.After taking hot baths， they put on bathing suits， allowed themselves to be with cold water， and then stood about dripping wet in drafty room.Some wore wet socks all day while others exercised in the rain until close to exhaustion.Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.If， then， cold and wet have nothing to do with catching colds， why are they more frequent in the winter? Despite the most pains-taking research， no one has yet found the answer， One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times， and this makes it easier for cold viruses to be passed on.No one has yet found a cure for the cold.There are drugs and pain suppressors such as aspirin， but all they do is relieve the symptoms.The passage mainly discusses ____.
