【文章內容簡介】 B.To reward them for their participation.C.To hide the intention of the experiment.D.To avoid the distraction during the game.【答案】 （1）B（2）C（3）C 【解析】【分析】本文是一篇說明文，介紹了外交宴席的心理學，研究表明，從中間菜采取的“家庭式”餐，可以大大改善后續(xù)談判的結果。 （1）考查細節(jié)理解。根據第二段中的“They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition. However, they also reasoned that it could instead lead people to bee more aware of others39。 needs and drive cooperative behavior as a result.”他們形成了一套理論，認為一方面，與他人一起吃飯可能表明糧食短缺，并加強了競爭的概念。然而，他們還推斷，這種方式可能會導致人們更加了解他人的需求，從而推動合作性的行為?？芍猣amilystyle指的是與別人一起用餐，故選B。 （2）考查細節(jié)理解。根據第二段中的“However, they also reasoned that it could instead lead people to bee more aware of others39。 needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.”然而，他們還推斷，這種方式可能會導致人們更加了解他人的需求，從而推動合作性的行為。 出于好奇心，他們做了一系列實驗。可知選C。 （3）考查細節(jié)理解。根據第三段中的“As a cover for the experiment, all participants were told this snack was to be consumed before the game began.”作為實驗的掩護，所有受試者都得告在游戲開始前就要吃完這些零食?？芍xC。 【點評】本題考點涉及細節(jié)理解題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，并結合題目要求，從而選出正確答案。4．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 biologically diverse and healthy.”可知，拍攝紀錄片的目的是了解狼是如何對生態(tài)有益的。故選D。 （3）考查細節(jié)理解。根據最后一段中的“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，這項研究再次證明了為什么保護這些食肉動物不僅對狼這個物種很重要，而且對生態(tài)系統(tǒng)的各個層面的物種都很重要。故這項研究的意義在于它有助于證明保護狼的重要性。故選B。 （4）考查主旨大意。本文主要講述了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，因為食草動物不會過度繁殖，從而保護了植物的生長。故選A。 【點評】本題考點涉及細節(jié)理解，詞義猜測和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。5．閱讀理解 It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his worldshaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them. But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life. Besides sharpness of brain and experience, here is another thing that is very importan
