【文章內(nèi)容簡(jiǎn)介】 portedly developing AR glasses to assist — or perhaps even replace — smartphones. Ericsson stated at February39。s Mobile World Congress how smart glasses could bee faster and lighter with a 5G connection, because instead of being weighed down with ponents, the glasses could rely on hardware for processing power. But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.（1）What does the author want to stress in Paragraph 1? A.The lightingfast speed of 5G.B.The expectation of 5G world.C.The difference between 4G and 5G.D.The internetconnected devices in our life.（2）What does the underlined word emblem in Paragraph 2 mean? A.Exhibition.B.Success.C.Symbol.D.Explanation.（3）We can infer from the text that ________. A.5G world won39。t e without AR glassesB.5G helps to create the artificial intelligence vehicleC.Apple pany is developing AR glasses worldwideD.Tech panies will face the fact that smartphones may be replaced（4）What will the author probably tell us next? A.How to fully expand 5G coverage.B.Smart glasses will bee faster and lighter.C.Why 5G isn39。t concentrated in big cities.D.The importance of infrastructure construction.【答案】 （1）A（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了我們離5G世界越來越近了。 （1）考查段落大意。根據(jù)第一段中的“Slowly but surely, we39。re moving closer and closer to 5G world.”緩慢但肯定的是，我們離5G世界越來越近了。可知，作者在第一段想強(qiáng)調(diào)“5G光速快?！惫蔬xA。 （2）考查詞義猜測(cè)。根據(jù)第二段中的“and that is to say, it is a sign of tim”也就是說，這是時(shí)間的標(biāo)志，”可知，劃線詞的意思是“標(biāo)志，象征”。故選C。 （3）考查推理判斷。根據(jù)第三段中的“This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.”這一點(diǎn)值得注意，因?yàn)閾?jù)報(bào)道，蘋果(Apple)等公司正在開發(fā)增強(qiáng)現(xiàn)實(shí)眼鏡，以幫助——甚至取代——智能手機(jī)?！?可知，我們可以從文中推斷，科技公司將面臨智能手機(jī)可能被取代的事實(shí)。故選D。 （4）考查推理判斷。根據(jù)最后一段中的“But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.”但是不要太激動(dòng)。與此同時(shí)，仍有很多工作要做，包括各種試驗(yàn)，以確保收音機(jī)能很好地配合硬件和基礎(chǔ)設(shè)施建設(shè)，這樣5G就不會(huì)只集中在大城市?！笨芍?，作者接下來可能會(huì)告訴我們“如何全面擴(kuò)大5G覆蓋?！惫蔬xA。 【點(diǎn)評(píng)】本題考點(diǎn)涉及段落大意，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科普類閱讀，要求考生根據(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。5．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(dòng)） 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(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
