They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine. The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. According to a recent study, a new genetically modified rice can prevent infections of HIV, the virus responsible for the disease AIDS. 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。即他認(rèn)為這些搜索數(shù)據(jù)可以有助于設(shè)定保護(hù)目標(biāo)。 （4）考查細(xì)節(jié)理解。s Wikipedia interest closely related to changes in nature”可知Mittermeier看到人們對維基百科的興趣是與大自然的變化密切相關(guān)的，感到非常興奮和意外。 （3）考查細(xì)節(jié)理解。即第三段的寫作目的是為了進(jìn)一步支持研究結(jié)果。 （2）考查推理判斷。根據(jù)第一段中的“Their online species searches follow the patterns of seasonal animal migrations (遷徙).”可知關(guān)于物種搜索，研究人員發(fā)現(xiàn)了他們遵循季節(jié)性動物遷徙的模式。它還展示了一種新的方式來了解人們有多關(guān)心自然，以及哪些物種和地區(qū)可能是最有效的保護(hù)目標(biāo)。他們的在線物種搜索遵循季節(jié)性動物遷徙的模式。s not getting close to nature.（4）Why does Richard think such search data is useful? helps to aim at conservation targets. increases interest in big data approaches. keeps track of trends in biologists39。s service. about Wikipedia behavior. at people39。 Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help.（1）What have researchers found about species searches? strengthen ties among people. affect the animal movements. differ in language backgrounds. reflect animal migration seasons.（2）What is the purpose of writing Paragraph 3? summarize the research process. further support the research findings. show the variety of species searches. present researchers39。re not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people39。 Mittermeier is encouraged by the search results.

That migratory behavior is acpanied by some human behavior. In Englishlanguage Wikipedia (維基百科), the online searches for migratory species tend to increase in spring when those birds arrive in the United States, said the lead author John Mittermeier. 【點評】本題考點涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。從而可以推斷出，千足蟲是擁有多種防御機(jī)制的物種。然而，它們也會釋放出有害 的 （3）考查推理判斷。t have to fax anyone a death certificate.

Researchers using lobsters (2f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don39。 The graceful sea hare is plain in taste in the first place, so it39。 Millipedes are tricky.

Even if they keep getting attacked, they won39。 Opossum (負(fù)鼠) Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomitedon dead bodies puts of most predators. Throwing up allows the vulture to fly away more quicklyand the vomit can hurt the aggressor39。 While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭氣) too. 【點評】本題考點涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇環(huán)境類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案。根據(jù)最后一段中的“…At the current rate, the world39。根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達(dá)一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng)，可知選D。故選C。 （2）考查詞義猜測。根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知，科學(xué)
