Many people believe that yellowing and wetness are the greatest enemy of stamps. In fact, stamps are afraid of not only wetness, but also light and dirty things. People protect their stamps in several different ways.

 To protect stamps,we should never touch the stamps with our hands.This avoids moving dirty things onto them. Stamp tweezers (镊子) should be used in all conditions.

 Stamps are printed things. The colour will slowly disappear if the stamps are put in the light for a long time. So we should not put stamps in the light for long. Direct sunlight must be avoided as well.

 Wetness is an important  problem for stamps. Some  collectors  will put stamps  in separate plastic (塑料) bags. However, it is possible that some stamps have taken in some water from the air before they are put into the plastic bags.Stamps yellow easily and rapidly after they take in wet air.To protect the stamps, some people also put the stamps into a special room which has a machine to  keep the air cool and dry. However, not many people can afford that.

 To keep stamps, stamp collectors usually put them under plastic covers. It is a common and simple way. This helps because the plastic cover keeps the stamps off the wet air. It also stops the fingersfrom touching te stamps.

 Some  collectors  prefer  to  store  stamps  inside  a  plastic  box  with  desiccants  (干燥剂).However, we should take care not to let the stamps. touch the desiccants. On top of that, don't  take your stamps out on a wet day.

    范进不看便罢，看了一遮，又念一遍，自己把两手拍了一下，笑了一声，道：“噫！好了！我中了！”说着，往后一交跌倒，牙关咬紧，不省人事。老太太慌了，慌将几口开水灌了过来。他爬将起来，又拍着手大笑道：“噫！好！我中了！”笑着，不由分说，就往门外飞跑，把报录人和邻居都吓了一跳。走出大门不多路，一脚踹在塘里，挣起来，头发都跌散了，两手黄泥，淋淋漓漓一身的水。众人拉他不住，拍着笑着，一直走到集上去了。众人大眼望小眼，一齐道：“原来新贵人欢喜疯了。”老太太哭道：“怎生这样苦命的事！中了一个甚么举人，就得了这个拙病！这一疯了，几时才得好？”娘子胡氏道：“早上好好出去，怎的就得了这样的病！却是如何是好？”众邻居劝道：“老太太不要心慌。我们而今且派两个人跟定了范老爷。这里众人家里拿些鸡蛋酒米，且管待了报子上的老爹们，再为商酌。”

    当下众邻居有拿鸡蛋来的，有拿白酒来的，也有背了斗米来的，也有捉两只鸡来的。娘子哭哭啼啼，在厨下收拾齐了，拿在草棚下。邻居又搬些桌凳，请报录的坐着吃酒，商议他这疯了，如何是好。报录的内中有一个人道：“在下倒有一个主意，不知可以行得行不得？”众人问：“如何主意？”那人道：“范老爷平日可有最怕的人？他只因欢喜狠了，痰涌上来，迷了心窍。如今只消他怕的这个人来打他一个嘴巴，说：‘这报录的话都是哄你，你并不曾中。’他吃这一吓，把痰吐了出来，就明白了。”众邻都拍手道：“这个主意好得紧，妙得紧！范老爷怕的，莫过于肉案子上胡老爹。好了！快寻胡老爹来。他想是还不知道，在集上卖肉哩。”又一个人道：“在集上卖肉，他倒好知道了；他从五更鼓就往东头集上迎猪，还不曾回来。快些迎着去寻他。”
