2023職稱英語(yǔ)理工類閱讀理解必備基礎(chǔ)練習(xí)題
Treatment for Dengue Fever
There is no vaccine to prevent dengue and no specific medicine to treat it, so the only defense is eradication of the mosquitoes that carry it and measures to protect people from mosquito bites.
The small white animals with pink eyes are kept in a special isolated room so that they will not be exposed to any bacteria or germs that might infect them. They have been altered to be susceptible to human diseases.
By infecting these humanized mice with strains of the dengue virus, investigators can study how the disease takes hold and what factors might cause the more serious and often deadly dengue hemorrhagic fever.
Lab workers infect the mice artificially with the virus, keeping precise records of how much virus and what type of virus is used. But natural transmission of dengue by mosquitoes involves certain proteins the insects inject into the skin, something that Rico-Hesse says is missing when mice are artificially infected in the lab.
Rico-Hesse and her colleagues are breeding mosquitoes in the laboratory to test various strains of the dengue virus transmitted to the mice by mosquitoes.
Which statement is correct according to Paragraph 1
B.Strong effect of certain medication can cure dengue fever.
D.Scientists have invented a vaccine that can prevent dengue fever
解析:問(wèn)題問(wèn)的是：根據(jù)第一段，正確的是哪一項(xiàng)?第一段中提到，沒(méi)有疫苗和藥物能預(yù)防或治愈登革熱，只有消滅所有攜帶病毒的蚊子才能防止被感染。由此可見(jiàn)，C選項(xiàng)正確
A.have red eyes.
C.are put in the room with lots of mosquitoes.
正確答案:D
According to the report, the virus strains that cause the more severe dengue and hemorrhagic fever are actually
B.from a special mosquito.
D.killable with a specific genetic variant
解析:問(wèn)題問(wèn)的是：能夠?qū)е赂訃?yán)重的登革熱和出血熱的病毒株實(shí)際上是什么?第六段最后一句中提到這兩種病毒株其實(shí)是屬于同一種基因變異體。因此選A。容易引起混淆的是D選項(xiàng)，其中提到了特殊變異體，只是該選項(xiàng)的意思是說(shuō)病毒可以被病毒的特殊變異體殺死，顯然不對(duì)。注意killable，是kill 和able組成的合成詞，意為可殺死的
A.Lab workers inject into the mice the fever virus with a syringe .
C.The artificial infection of virus has exactly the same effect as the natural one.
正確答案:A
What is the authors attitude to the future of the researchers work
B.Pessimistic.
D.Sarcastic
解析:問(wèn)題問(wèn)的是：作者對(duì)該項(xiàng)研究的前景持何種態(tài)度?縱觀全文，作者始終非常客觀的敘述試驗(yàn)的細(xì)節(jié)及進(jìn)展情況，包括最后對(duì)前景的展望都是引用研究人員的原話。因此，他的態(tài)度應(yīng)該是客觀的。C選項(xiàng)正確
