【正文】 腦的敏捷更重要，人們通常會發(fā)現(xiàn)一個人在他一生的晚期才達到頂峰。根據(jù)對愛因斯坦所的發(fā)現(xiàn)可知，他的偉大的發(fā)現(xiàn)是在2025歲之間，更是印證了人類大腦在20年代初達到了巔峰，可推斷出，本段主要研究人類大腦巔峰期，故選B。愛因斯坦在20到25歲之間做出了所有震驚世界的發(fā)現(xiàn)。根據(jù)第一段“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, ... 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.” 人們發(fā)現(xiàn)，16歲以后，我們的腦細胞數(shù)量開始以每年幾百萬的速度減少。人們要用智慧來決定做什么才是最好的。. is always a waste of time to make plans about the future is human nature to make attempts on what looks impossible should always challenge the impossible to push the society forward has to use wisdom in deciding what is the best thing to do【答案】 （1）B（2）A（3）D（4）D 【解析】【分析】本文是一篇說明文，介紹了人類的大腦在20歲左右于巔峰，在以后的成就多數(shù)是因為需要豐富的經(jīng)驗。 . helps to avoid various mistakes contributes to one39。 and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human nature。 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. 4．閱讀理解 故選A。 （4）考查主旨大意。故這項研究的意義在于它有助于證明保護狼的重要性。 （3）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 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A。 （1）考查詞義猜測。Yellowstone National Park owes its healthy ecosystems to wolves.D.The fear of wolves is beneficial to ecosystems.B.It shows the plex relationships between species.D.It proves wolves feed on hundreds of species.B.To record how Aaron Wirsing observed wolves.D.To introduce how wolves behave in the wild.B.D.C.B. 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. 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.d never have seen these responses if the park hadn39。 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.3．犇犇閱讀理解 根據(jù)最后一段中的Actually. AI is still no match for human qualities.可知，人工智能仍無法與人類素質(zhì)相匹敵，由此可知，在不久的將來，人工智能新聞主播不會取代人類新聞主播，故選C。 t always change according to the content. As a result, her expressions look anything but human.可知，真正的難點在于第三技術(shù)，使辛曉萌的面部表情根據(jù)新聞報道的內(nèi)容而變化，事實上，辛曉萌的表情不總是隨著內(nèi)容而變化，她的表情一點也不像人類，由此可知，第三技術(shù)還遠遠不夠成熟，故選D。 （3）考查推理判斷。根據(jù)第二段中的Unlike previous news robots though, Xin does not read news like a cold machine。s why many news anchors were worried: Will AI replace us in the near future?可知，擔心將來自己的工作會被人工智能取代的新聞主播一定不愿意透露下面這個消息：上周日，新華社新聞主播辛曉萌成為世界上第一位女性人工智能新聞主播，由此可知畫線詞詞義為不愿意的，故選B。根據(jù)第一段中的Xin Xiaomeng began working as the world39。Xin Xiaomeng s expressions vary so naturally that they are true to life【答案】 （1）B（2）A（3）D（4）C 【解析】【分析】本文是一篇說明文，上周日，新華社新聞主播辛曉萌成為世界上第一位女性人工智能新聞主播，作者介紹了人工智能背后的技術(shù)，并指出在不久的將來，人工智能新聞主播不會取代人類新聞主播。Al news anchors won39。human news anchors should learn from AT anchors to save their jobsB.This technology remains at the theoretical stageD.This technology is very perfect so farB.They could interview sports starsD.They read news without expressions.B.D.C.B.t always change according to the content.
