题目内容
6.An oral drug,named ERDRP-0519,was invented.It is specifically designed to protect people who got infected measles(麻疹) from spreading the virus to others.Like the flu,measles spreads through the air by breathing,coughing or sneezing.There is typically a time,about two weeks,between becoming infected with the virus and the beginning of symptoms like skin rash(皮疹),runny nose,heavy cough and high fever."This therapy application determines the desired characteristics of the drug,which are orally available,cost-effective manufacture and high stability,"Richard Klemperer,professor of Georgia State University,told reporters last Wednesday.
"With these criteria in mind,we have developed a small drug that blocks the measles virus over the past years,which is essential for copy of the virus."
The researchers tested the drug in rats infected with canine distemper virus(犬瘟病),which is a close relative of measles virus.They found that all of the infected rats treated with the drug survived the deadly infection,showed no clinical signs of disease and developed a strong protective immune response.
The drug could be used to treat friends,family and other social contacts of a person infected with measles virus,which have not developed symptoms yet but are at risk of having caught the disease,Klemperer said truthfully.
"The emergence of strong antiviral immunity(抗病毒免疫力) in treated animals is particularly encouraging,since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population,"Klemperer said.
The researchers emphasized the drug is not intended as a substitute for vaccination,but as an additional weapon to get rid of the measles.They planned to test the drug's safety in larger animals,before moving into clinical trials in humans.
"If our next series of studies confirms that the human situation mirrors what we have seen in rats,then this drug may make a major contribution to getting rid of measles by preventing local outbreaks"Klemperer said.
Despite the existence of an effective vaccine,annual measles deaths worldwide have remained constant at around 150,000since 2007.The reasons for this are the highly infectious nature of the virus,in the developing world largely due to issues of resources,and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.
58.If a boy got infected by measles virus,he might NOT show the symptom likeD.
A.runny nose
B.bad cough
C.high fever
D.sick stomach
59.From what Klemperer said,we know that the drugC.
A.is only intended as a substitute for vaccination
B.can only save those infected individuals from disease
C.is cost-effective and high stability for curing measles
D.has the same effect on human as on larger animals
60.The best title of the passage isA .
A.the Introduction of a New Oral Drug
B.the Desired Characteristics of Drugs
C.the Common Symptoms of Getting Measles
D.the Application of Post-exposure Therapy.

点评 做阅读时经常犯错的主要原因是,仅凭读过文章后残留在脑海中的一丝印象来勾选答案,这样便很容易掉入出题人故意设布下的题目陷阱.所谓阅读理解,对于题目的理解一定要忠实于原文,因此,每一道题都应该与原文作全面的对比与核查,再得出答案.也就是说,阅读理解的每一道题目,在原文都应该有明确的出处,我们把这一出处叫做原文相关句,(1)排除与原文相关句主题不一致的选项(2)排除与原文相关句态度相反的选项 (3)排除用于过于极端或负面的选项(4)注意结合文章主旨和主题去排除.
