The US team say the results, published in Nature, are striking and should encourage research efforts. Tests in humans could begin in months. But even if these go well, a licensed vaccine for widespread use to protect those at most risk 173。 such as pregnant women 173。 would still be years away, experts advise. Zika has been spreading across Central and South America and, most recently, Africa. More than 60 countries and territories now have continuing transmission(傳播) of the disease, which is carried by mosquitoes. The virus causes serious birth damages during pregnancy and has been declared a global public health emergency. Now, developing a vaccine for pregnant women to protect their unborn babies is an international research priority(優(yōu)先事項). US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice – one based on bits of genetic(基因的) code from the virus and another that is an inactive (and therefore harmless) copy of Zika. Both worked well, protecting every mouse that was immunised against the virus. In parison, all of the mice not given the vaccine caught Zika after they were exposed to it. Researchers say they will push ahead with developing the needed virus vaccine. There are many existing vaccines for other disease that use this type of technology, while there are relatively few DNA173。based vaccines. Of course, future tests will need to check the vaccine is safe and effective in humans, as well as how long the immunity might last.（1）If the tests in humans go smoothly, . A.a vaccine for use in the laboratory will be still be years away.B.pregnant women in Africa will be the first to benefit from the vaccine.C.a licensed vaccine will still not be accessible in a short term.D.The Zika virus will cause less serious birth defects during pregnancy in months.（2）Which of the following statements is NOT true? A.many countries are actively involved in the research of the Zika vaccine.B.US scientists have tested more than two types of Zika vaccine in mice.C.None of the mice given the vaccine caught Zika.D.It is still unknown whether the vaccine is safe and effective.（3）Which can be the best title for the passage? A.Zika vaccine 39。works very well39。 in miceB.Zika vaccine still has a long way to goC.International researches into Zika have paid offD.More attention has been paid to Zika vaccine【答案】 （1）C（2）B（3）A 【解析】【分析】本文是一篇說明文，介紹了科學(xué)家發(fā)現(xiàn)一種實驗性疫苗可以保護(hù)小鼠免受寨卡病毒侵襲。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的But even if these go well, a licensed vaccine for widespread use to protect those at most risk 173。 such as pregnant women 173。 would still be years away可知，但是，即使這些進(jìn)展順利，一種廣泛用于保護(hù)高危人群的授權(quán)疫苗仍需數(shù)年時間，也就是說如果人體試驗進(jìn)展順利的話，短期內(nèi)仍無法獲得授權(quán)疫苗，故選C。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice可知，美國科學(xué)家在白鼠身上只測試了兩種而不是兩種以上的寨卡病毒，故選B。 （3）考查主旨大意。根據(jù)第一段中的A single dose(劑量) of an experimental vaccine(疫苗) can protect mice against the Zika(寨卡) virus,可知，一種實驗性疫苗可以保護(hù)小鼠免受寨卡病毒侵襲，由此可知，本文主要介紹的是寨卡病毒疫苗對小白鼠非常有效，故選A。 【點評】本題考點涉及細(xì)節(jié)理解和主旨大意兩個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文進(jìn)行推理，歸納，從而選出正確答案。5．犇犇閱讀理解 News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world39。s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession. Unlike previous news robots though, Xin does not read news like a cold machine。 she reads it almost like a human being. The muscles on her face stretch and relaxand her reactions changeas she continues reading. That39。s why many news anchors were worried: Will AI replace us in the near future? To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro electric motors behind her face move to make her expressions seem more human. Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person39。s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs Both the technologies
