18.Although we already know a great deal about flu,and although the World Health Organizations is constantly collecting detailed information from its chain of flu reference laboratories throughout the world,it is extremely difficult for epidemiologists,who study infectious diseases,to predict when and where the next flu epidemic will occur,and how serious it will be.There are three kinds of flu virus,know as A,B and C.Flu C virus is relatively stable and causes mild infections that do not spread far through the population.The A and B types are unstable,and are responsible for the epidemics that cause frequent concern.Following any virus attack,the human body builds lip antibodies (抗体) which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection.Variability (可变性) is less developed in the flu.B virus,which affects only human beings.As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards,since nearly everyone Jill have built up antibodies and will be immune.The flu A virus,which affects animals also,is extremely unstable and is responsible for some of the worst outbreaks of the disease,such as the world epidemic,of 1918 &1919,when about half the world's population were infected and about twenty million people died,some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria.Accurate prediction is difficult because of the complication of the factors.A particular virus may be related to one to which some of the population have partial involved immunity.The extent to which it will spread will depend on factors such as its own strength,or virulence (病毒性),the ease with which it can be transmitted and the strength of the opposition it encounters (遇到).Scientists,however,have a reliable general picture of the world situation.
57.Which of the following is the most appropriate title for the passage?D
A.Symptoms of Flu
B.Variability of Flu Virus
C.The Major Organization against Flu Virus
D.Man Vs Flu Virus
58.What does the author say about the Flu B virus?C
A.B Virus is relatively stable and causes mild infections that do not spread far through the population.
B.B virus is extremely unstable and is responsible for some of the worst outbreaks of the disease.
C.B Virus is unstable,and is responsible for the epidemics that cause frequent concern.
D.B virus has a very developed variability,and it affects only human beings.
59.Which of the following is NOT mentioned as a factor contributing to the extent to which a virus spreads?C
A.The strength of the virus.
B.The ease with which the virus can be transmitted.
C.The immunity the virus can bring about.
D.The strength of the opposition.
60.This article is quite probably _A.
A.a special science report B.a piece of news
C.an introduction to a book D.a scientific fiction.
分析 这是一篇科普文.介绍尽管我们对于流感病毒了解很多,世界卫生组织也定时发布流感信息,但是流行病学家却不能预测下一次流感什么时候发生,有多么严重.人们已经知道有三种流感病毒,它们有各种不同的特点,病毒的传播取决于它本身的强度,毒性,它被传播的难易程度,和它遇到的抗体的强度.但是科学家相信他们对世界形势有可靠的了解.
解答 57.D.主旨大意题.根据首段可以知道尽管我们对于流感病毒了解很多,世界卫生组织也定时发布流感信息,但是流行病学家却不能预测下一次流感什么时候发生,有多么严重.有因为后段中对于三种流感病毒的解释以及人类对于这种病毒的反应和抵抗,所以中心词是人类和流感病毒,因此答案是D.
58.C.细节题.根据第二段中The A and B types are unstable,and are responsible for the epidemics that cause frequent concern可以知道AB两者病毒是不稳定的,是流行病频繁发生的原因,因此答案是C.
59.C.细节题.根据末段中的The extent to which it will spread will depend on factors such as its own strength,or virulence (病毒性),the ease with which it can be transmitted and the strength of the opposition it encounters (遇到).可以知道病毒的传播取决于它本身的强度,毒性,它被传播的难易程度,和它遇到的抗体的强度,这里没有提到C项,所以答案是C.
60.A.推理判断题.根据上文可以知道这是一个科普文,所以答案是A.a special science report,指特别的科学报告.
