18、ing Comprehension Part A 阅读理解 Part A(共 20 题)Directions:Read the following four texts.Answer the questions below each text by choosing A,B,C,and D.(40 points)说明:阅读下面四篇文章并回答每篇文章后面的问题。(每小题2 分,共计 40分)注意:本题只有一个正确选项。Text 1 Influenza A(H5N1)is an influenza A virus subtype that occurs mainly in birds and is
19、 highly contagious among birds.Outbreaks of highly pathogenic H5N1 among poultry and wild birds are ongoing in a number of countries.H5N1 does not usually infect people,however,a small number of human cases of H5N1 infection have been reported in association with these outbreaks.Most of these cases
20、have occurred from direct or close contact with infected poultry or contaminated surfaces.And while the H5N1 virus does not now infect people easily,infection in humans is very serious when it occurs;so far,about half of people reported infected have died.The avian influenza A(H5N1)epizootic in Asia

24、m human cases in Vietnam and Thailand shows resistance to the antiviral medications amantadine and rimantadine,two of the medications commonly used for treatment of influenza.This would leave two remaining antiviral medications(oseltamivir and zanamivir)that should still be effective against current
25、ly circulating strains of H5N1 virus.Efforts to produce vaccine candidates that would be effective against avian influenza A(H5N1)viruses are under way.However,it will likely require many months before such vaccines could be mass produced and made widely available.Research suggests that currently ci
