They became the world39。s first kids to be “taught” by a digital teacher”可知，從新學年開始，新西蘭奧克蘭的小學生將成為世界上第一批被機器人老師教的孩子。之后文章就此展開，由此可推斷出he World39。s First Digital Teacher Appears in Classroom最符合本文的標題。故選B。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科教類閱讀，要求考生在捕捉細節(jié)信息的基礎(chǔ)上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。3．犇犇閱讀理解 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. Yellowstone National Park is a typical example of just how wolves can help repair an ecosystem. An October 2018 study analyzed 40 years of research on large animals inside the park. Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the plexity of biological interactions（互動） in the park, explained Mark Boyce, a professor in the Department of Biological Sciences. We were really surprised at that and we39。d never have seen these responses if the park hadn39。t adopted ecologicalprocess management—allowing natural ecological processes to take place with least human intervention. After the wolves were reintroduced at Yellowstone, willow and cottonwood trees increased in number. The population of bears and bison also rose and what was once a ruling deerwolf interaction is now more diverse. 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. 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. The fear they bring along may be the very angle that helps save them from dying out.（1）What does the underlined word anticipate in paragraph 3 probably mean? A.Expect.B.Understand.C.Notice.D.Accept.（2）For what purpose was a documentary made? A.To introduce how wolves behave in the wild.B.To show how wolves benefit from ecosystems.C.To record how Aaron Wirsing observed wolves.D.To study what good wolves can do to ecosystems.（3）What is the significance of the research? A.It proves wolves feed on hundreds of species.B.It helps prove the importance of protecting wolves.C.It shows the plex relationships between species.D.It provides evidence that wolves are endangered animals.（4）What is the main idea of the passage? A.The fear of wolves is beneficial to ecosystems.B.The fear of wolves put them in danger of disappearing.C.Yellowstone National Park owes its healthy ecosystems to wolves.D.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】本文是一篇說明文，研究表明人類以及其他動物對狼的恐懼對維持健康、平衡的生態(tài)系統(tǒng)是有益的，其中黃石公園灰狼的引進就是一個典型的例子。 （1）考查詞義猜測。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。故選A。 （2）考查細節(jié)理解。根據(jù)第五段中的“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 biologic
