【正文】 the century. However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg? A.To study a newly discovered ecosystem.C.To explore the geography of the Larsen C ice shelf.（2）What do the underlined words this one in the fourth paragraph refer to? A.Climate change in Antarctica.C.The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text? A.It is part of an ice shelf in the Arctic.C.It has uncovered an unknown ecosystem in Antarctica.（4）What can we infer from the last paragraph? A.The ice sheets in Greenland and Antarctica are melting at a steady rate.C.By 2100, the sea level will have risen to a much higher level than now.【答案】 （1）B（2）C（3）D（4）D 【解析】【分析】本文是一篇說明文，南極地區(qū)的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。 （1）考查細(xì)節(jié)理解。故選B。根據(jù)第三段中的“The calving of A68 provides us with a unique opportunity to study marine life...”可知A68冰山的形成為科學(xué)家提供了研究海洋生物的獨(dú)一無二的機(jī)會(huì)，所以Professor David Vaughan認(rèn)為科學(xué)家要果敢地抓住這次機(jī)會(huì)，故this one指的是A68冰山和它下面的生態(tài)系統(tǒng)。 （3）考查細(xì)節(jié)理解。 （4）考查推理判斷。s oceans will be, on average, at least 60cm higher by the end of the century.”按目前的速度，世界的海洋到本世紀(jì)末平均至少升高60厘米，選D。2．犇犇閱讀理解 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。 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. 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。. A.pregnant women in Africa will be the first to benefit from the vaccine.C.The Zika virus will cause less serious birth defects during pregnancy in months.（2）Which of the following statements is NOT true? A.US scientists have tested more than two types of Zika vaccine in mice.C.It is still unknown whether the vaccine is safe and effective.（3）Which can be the best title for the passage? A.works very well39。Zika vaccine still has a long way to goC.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(shí)驗(yàn)性疫苗可以保護(hù)小鼠免受寨卡病毒侵襲。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。 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(shí)間，也就是說如果人體試驗(yàn)進(jìn)展順利的話，短期內(nèi)仍無法獲得授權(quán)疫苗，故選C。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。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(shí)驗(yàn)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。3．犇犇閱讀理解 But where do these phonemes e from and why do they shift over time?

But neither can it be reduced to the purely physical, as our inability to understand or even to recognise foreign languages makes clear. The food we eat shapes our jaws, and our jaws in turn shape the sounds of our language. The ease with which we eat probably shapes our thought too, as anyone who has suffered toothache could testify. What we eat may have shaped the sounds of our language, but how we eat changes how we feel and what we use language to express. A family meal is very different from a sandwich at the office desk, even if the calorie is the same. Food has purposes and meanings far beyond keeping us alive and pleasing the Palate (味覺).（1）Compared with adults, babies could more easily create significant noisesB.understand the Greek languageD.Lips and teeth.Jobs and habits.Age and regions.Food and thinking.（3）The reason for farmers39。.
