【正文】 Then there are the asyetunknown jobs that will be created by AI. The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks—provided the task is in one field with a lot of data—it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so. In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards39。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和主旨大意三個(gè)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，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。本文主要講述了人類以及其他動(dòng)物對(duì)狼的恐懼對(duì)維持健康、平衡的生態(tài)系統(tǒng)是有益的，因?yàn)槭巢輨?dòng)物不會(huì)過(guò)度繁殖，從而保護(hù)了植物的生長(zhǎng)。故選B。根據(jù)最后一段中的“The research is one more piece of evidence for why protecting these top predators is important not just for wolves as a species, but for hundreds of species at every level of an ecosystem.”可知，這項(xiàng)研究再次證明了為什么保護(hù)這些食肉動(dòng)物不僅對(duì)狼這個(gè)物種很重要，而且對(duì)生態(tài)系統(tǒng)的各個(gè)層面的物種都很重要。故選D。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的We were really surprised at that可知，黃石公園在意想不到的方面從重新引入狼中獲益。The introduction of wolves in Yellowstone National Park is a success.【答案】 （1）A（2）D（3）B（4）A 【解析】【分析】本文是一篇說(shuō)明文，研究表明人類以及其他動(dòng)物對(duì)狼的恐懼對(duì)維持健康、平衡的生態(tài)系統(tǒng)是有益的，其中黃石公園灰狼的引進(jìn)就是一個(gè)典型的例子。The fear of wolves put them in danger of disappearing.C.It provides evidence that wolves are endangered animals.（4）What is the main idea of the passage? A.It helps prove the importance of protecting wolves.C.To study what good wolves can do to ecosystems.（3）What is the significance of the research? A.To show how wolves benefit from ecosystems.C.Accept.（2）For what purpose was a documentary made? A.Notice.Understand.Expect. To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy. In this documentary, biologist Aaron Wirsing explored why wolves and other top predators （捕食者）were needed for diverse ecosystems to develop. Using a simple video camera, Wirsing is gaining a unique view point on predatorprey relationships and changing the way we think about wolves.t adopted ecologicalprocess management—allowing natural ecological processes to take place with least human intervention. Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the plexity of biological interactions（互動(dòng)） in the park, explained Mark Boyce, a professor in the Department of Biological Sciences. We were really surprised at that and we39。 Wolves strike fear into the hearts of many species, humans included. Our fear of them has brought them to the edge of dying out, as we have cruelly killed them as petitors and troublemakers. But researchers are discovering that the very fear they put into prey（被捕食者）species is exactly what helps make ecosystems（生態(tài)）healthy. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科研類閱讀，要求考生準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。由此可知。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （3）考查細(xì)節(jié)理解。由此推斷出劃線詞所在的句子意思是我們所吃的食物給環(huán)境帶來(lái)了巨大代價(jià)。caused greenhouse gas emissions.
