18.Tamiflu does not kill but prevents H1N1from further proliferation (繁衍) till the virus limits itself in about 1-2weeks (its natural cycle).H1N1,like other Influenza A viruses,only infects the upper respiratory tract and proliferates (only) there.The only way of entry are the nostrils(鼻孔) and mouth/throat.In a global epidemic of this nature,it's almost impossible not coming into contact with H1N1.
Contact with H1N1is not so much of a problem as proliferation is.
While you are still healthy and not showing any symptoms of H1N1infection,in order to prevent proliferation,some very simple steps can be practiced:
1.Frequent hand-washing.
2."Hands-off-the-face"approach.Resist all temptations to touch any part of face (unless you want to eat or bathe).
3.Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt).H1N1takes 2-3days 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 preventative method.
4.Similar to 3above,clean your nostrilsat least once every day with warm salt water,Which is very effective in bringing down viral population.
5.Strengthen your natural immunity with foods that are rich in Vitamin C.If you have to supplement with Vitamin C tablets,make sure that it also has Zinc to boost absorption.
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 ways to prevent,within means of most households,and certainly much less painful than to wait in long queues outside public hospitals.

57.What part of a person's body do H1N1flu viruses mainly infect?B
A.one's lung            B.the upper respiratory tract

You are entering a world far different from the one my generation entered.My generation grew up with no MTV, no college loan,no $175 sneakers,no underwear worn in public and very little jewelry worn on the tongue.Yet somehow we broke through and,achieved all these things,and more.I believe that your generation is far more elegant and caring than my own.You ask questions: "What is the meaning of life?" "How can I make a fortune with almost no money down?" "Why do we have to sit round in the hot sun listening to an opening speech? "

I do not recall who it was that spoke at my own graduation.Whoever it was,I know I looked to him for wisdom and guidance,just as you now look to me.I suppose if there is one single suggestion I'd like to leave with you,it is like this: concentrate on what you are doing.If you have decided to do it well,you will be successful,no matter how hard your situation is.

Act bravely.Do not fear making mistakes; if you make one,look out.

Make a contribution to our society.Even though 70 percent of you will be lawyers,still I say to you: Try to do something useful with your life,if only in your spare time.

In a very real sense,your graduation here today is not an ending but a commencement.If I may say so,this is,in fact,the first day of the rest of your lives.I realize it is a bit shocking to look at graduation this way,but I believe we must.Thank you,and lots of luck.You'll need it.
