   Most N95 respirators are designed to filter 95% particulates of 0.3μ, while the size of H1N1 virus is about 0.1μ. Hence, dependence on N95to protect against H1N1 is like protecting against rain with an umbrella made of mosquito net.
   Tamiflu does not kill but prevents H1N1 from further proliferation till the virus limitsitself in about 1—2 weeks (its natural cycle). H1N1, like other Influenza A viruses, only infects the upper respiratory tract and proliferates (only) there. The only portals of entry are the nostrils and mouth / throat. In a global epidemic of this nature, it’salmost impossible not coming into contact with H1N1 in spite of all precautions.
   Contact with H1N1 is not so much of a problem asproliferation is.
   While you are still healthy and not showing any symptoms ofH1N1 infection, in order toprevent proliferation, aggravation of symptoms and development of secondary infections,some very simple steps—not fully highlighted in most official communications—can be practiced (instead of focusing on how to stock N95 or Tamiflu):
   1. Frequent hand-washing (well highlighted in all official communications).
   2. “Hands-off-the-face” approach. Resist all temptations to touch any part of face (unless you want to eat or bathe).
   3. Gargle twice a day with warm salt water (use Listerine if you don’t trust salt). H1N1 takes 2-3 days after initial infection in the throat / nasal cavity to proliferate and show characteristic symptoms. Simple gargling prevents proliferation. In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one. Don’t underestimate this simple, inexpensive and powerful preventativemethod.
   4. Similar to 3 above, clean your nostrils at least once every day with warm salt water. Not everybody may be good at Jala Neti or Sutra Neti (very good Yoga asanas to clean nasal cavities), but blowing the nose hard once a day and swabbing both nostrils with cotton buds dipped in warm salt water is very effective in bringing down viral population.
   5. Boost your natural immunity with foods that are rich in Vitamin C (Amla and other citrus fruits).
   6. Drink as much of warm liquids as you can. Drinking warm liquids has the same effect as gargling, but in the reverse direction. They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm.
   7. All these are simple waysto prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals.
  
   N95口罩是用来阻隔95%的0.3μ微粒,而H1N1病毒的大小是0.1μ左右。 所以,靠N95口罩防H1N1就像用蚊帐来挡雨。
   克流感不是用来杀死H1N1病毒,它只能抑制病毒在其 1-2周的自然生存周期中繁衍。H1N1跟其它A型流感的病毒一样,感染部位只限于上呼吸道,并在那里繁殖。它的唯一入侵途径是口鼻喉,这种全球性的流感,几乎无人能置身事外。
   但接触到H1N1病毒,并不像H1N1传染的问题那么严重。
   当你身体健康,尚未出现H1N1感染症状时,你可以用以下几种间单的方式来 避免少量的H1N1病毒在你体内(如果有接触到的话)繁殖、出现病症、及恶化 成二期感染:
   1. 常洗手。
   2. 手绝不碰脸,除非是洗脸。
   3. 每天用温盐水(或漱口水)漱口二次。 H1N1在鼻喉腔内经过 2-3天才开始增生并出现症候,简单的盐水漱口可以抑制病毒繁衍,等于是健康人 的克流感,千万不要小看这简单的步骤。
   4. 同上,每天用温盐水清洗鼻孔至少一次,吸口气用力将鼻内物质喷出,最后以棉花棒沾温盐水清洁鼻孔。这对降低鼻中的病毒量非常有效。
   5. 多吃维生素C含量高的食物以增强免疫力。
   6. 多喝温开水或热汤,功效和漱口一样,只是方向相反。冲到胃里的病毒是无法生存的。
   7. 这些都是在家里就做得到的简便预防法,远比痛苦地在医院候诊好得多。

人们对允许学生虚构想象进行作文,不必拘泥于写真人真事的做法,有的赞成,有的反对,众说不一。应该说,旨在提高学生写作能力的任何尝试,都是有益的,都有助于研究探讨中学生作文的一般过程及其规律。但也毋需讳言,并不是任何一种做法,都尽善尽美,就不同的观点展开讨论,进行研究,对于逐步引导学生走向作文的“自由王国”,有效地提高中学生的写作能力,无疑是有意义的。基于这种认识,本文就中学生作文能否虚构,谈几点浅见
