They want to look worldly or cool. But not everyone is impressed by this idea, though.”可知，不需要眼鏡的人有時戴眼鏡只是為了時尚，他們想顯得酷一些，但并不是每個人都對這個想法印象深刻，可知，對于那些追求時尚而戴眼鏡的人來說，人們的態(tài)度是既有人支持也有人反對，故選C。根據(jù)第四段中的“A number of studies have found people who wear glasses are seen as smarter, hardworking and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses soften their appearance.”可知，許多研究發(fā)現(xiàn)，戴眼鏡的人被視為更聰明、更勤奮、更誠實，眼鏡使他們看起來更溫和，許多律師利用這個想法來幫助他們贏得官司，可知，一些律師讓他們的當(dāng)事人在法庭上戴眼鏡是因為戴上眼鏡有助于塑造一個道德的形象，故選A。根據(jù)第三段中的“Just because something is connected to something else does not mean one of those things caused the other.”可知，僅僅因為某物與其他事物相聯(lián)系并不意味著其中一個事物導(dǎo)致了另一個事物，這是對畫線詞的解釋說明，因此此處是說重要的是要記住這些都是沒有被證實的原因的聯(lián)系，科學(xué)家稱之為相關(guān)性，由此可知畫線詞詞義為“相關(guān)聯(lián)、聯(lián)系”，故選B。根據(jù)第二段中的“The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses.”可知，研究表明，智力與身體特征有關(guān)，其中一個特征就是視力，在10個更聰明的人中，他們需要眼鏡的幾率更高，也就是說戴眼鏡與高智商有關(guān)，故選D。Indifferent.【答案】 （1）D（2）B（3）A（4）C 【解析】【分析】本文是一篇說明文，介紹了研究發(fā)現(xiàn)戴眼鏡和高智商有關(guān)，文章還指出有些人只是為了追求時尚而戴眼鏡。MixedNegative.Positive.Because it can prove the clients39。 qualities.Because it can mislead the witnesses.C.Because it can create a moral image.D.C.B.Wearing glasses is associated with higher IQ.（2）What does the underlined word in Paragraph 3 mean?

Justin Bieber is just one highprofile fan of fashion glasses.（1）What does the new study show? A. t found guilty. s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure. The scientists studied the genes of thousands of people between the ages of 16 and study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health. 7．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(hù)狼的重要性。 （3）考查細(xì)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(jì)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.6．犇犇閱讀理解 根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識別物體和成像形狀及體積的準(zhǔn)確性，故選B。檢查行李總是需要人力，我們希望開發(fā)一種互補(bǔ)的方法來減少人力，可推知選A。s in airports. Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.” （3）考查推理判斷，根據(jù)第五段中的“In large public areas, it39。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的“The detection system analyzes what happens when wireless signals go through and bounce off objects or materials.”這個檢測系統(tǒng)分析信號在物體和材料上穿透和反射時會發(fā)生什么。Examining.【答案】 （1）B（2）D（3）A（4）B 【解析】【分析】本是一篇說明文，介紹了研究人員發(fā)現(xiàn)，WiFi可用于可用于安檢。C.Improving.To research dangerous objects.（4）Which of the following can replace the underlined word “ameliorating in the last paragraph?

In large public areas, it39。 When it was tested on a backpack, the accuracy rate topped 95 percent. But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools, the team said, noting its design can inspect bags or luggage without being an exposure to privacy. Research suggested that WiFi can now be used to estimate the volume of liquids such as water, acid, alcohol a
