26、学习如何与他人互动，行为正直等。空处需用连接词引导宾语从句，根据空后“right or wrong”和句意可知，whether“是否”，引导宾语从句，符合题意。故填whether。【20题详解】考查连接词。句意同上。此处表示“如何与他人互动”，所以空处需用how+动词不定式作动词learn的宾语。故填how。第二部分：阅读理解（共两节，38 分）第一节（共 14 小题；每小题 2 分，共 28 分）阅读下列短文，从每题所给的 A、B、C、D 四个选项中，选出最佳选项，并在答题纸上将该项涂黑。AUSA TODAY 10Bests Readers Choice Awards are current

C【解析】【分析】这是一篇说明文。一方面，人们在努力促进塑料的回收利用，减少塑料的使用，一方面石油与天然气如果需要获得更多利润，需要生产更多塑料，而塑料的回收意味着利润的减少。【24题详解】细节理解题。根据第一段中的“But the truth i
45、s that the vast majority of all plastic produced cant be or wont be recycled. In 40 years, less than 10%of plastic has been recycled.”可知但事实是，绝大多数生产的塑料不能或不会被回收利用。在40年里，只有不到10%的塑料被回收。所以百分之百回收塑料的这个目标是不现实的。故选D项。【25题详解】推理判断题。根据第三段中的“But the more plastic is recycled, the less money the industry will make
46、by selling new plastic. And those profits have become increasingly important. Companies have told shareholders（股东）production overall is now expected to rise three times by 2050,”可知回收的塑料越多，这个行业通过销售新塑料赚的钱就越少。然而这些利润变得越来越重要。公司对股东说在未来几年随着电动汽车的使用，交通运输业中石油和天然气的需求减少，利润会下降。行业领袖预计，未来10年，化工行业对石油和天然气的需求将远远超过运输行
47、业。由此推断，在交通运输业利润减少的情况下，石油和天然气公司为了获取利润，会生产更多塑料。故选C项。【26题详解】词义猜测题。根据划线词所在句子Efforts to reduce plastic use are mounting nationwide可知减少塑料使用的努力正在全国范围内mounting。 根据前文“The plastics industry officials said the industry is providing money for new technology that they believe will get recycling plastic up to sca
48、le.”和“the industry is spending money on advertisements and public relations to promote plastic recycling.”可知塑料产业和石油天然气行业都在促进塑料的回收利用，所以由此推断，减少塑料使用的努力正在全国范围内“增加”，mounting与A项（increasing）意思相同，故选A项。【27题详解】主旨大意题。根据文章最后一句话“Efforts to reduce plastic use are mounting nationwide, but any plan to slow the grow
49、th of plastic will face an industry with billions of dollars of future profits to lose.”可知减少塑料使用的努力正在全国范围内展开，但任何减缓塑料增长的计划都将面临某个行业未来会损失数十亿美元利润的局面。而文章也是围绕着这个写的，第一二段着重强调了人们为回收利用塑料所做的努力，第三段提出石油与运输行业利润的减少需要生产更多塑料赚钱，塑料生产的减少意味着利润的损失。第四段总结全文再次强调是要利润还是减少塑料的这个困境。故C项（回收塑料还是卖更多？）最能够概括文章大意。故选C项。CNew App Helps Pe
50、ople Remember FacesLarge gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn peoples names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.The app, called SocialRecall, conne
51、cts names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody,” says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.After
52、 receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendees face, the app ident
53、ifies the individual, displays the persons name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the apps creators say it automatically deletes users data after an event.Ann Cavoukian, a privacy expert who runs the Privac

She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in ano

To use this app, a person first acquires an image of so

59、sures.【答案】28. B 29. D 30. A【解析】【分析】本文是一篇说明文。文章主要介绍一款新的应用程序帮助人们识别面孔，但也有可能泄露隐私。【28题详解】推理判断题。根据文章第二段“The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions.(这款名为SocialRecall的应用软件可以通过智能手机摄像头和面部识别功能将名字和
60、人脸联系起来，从而避免了正式介绍的必要)”可推知，SocialRecall是用来识别人的。故选B。【29题详解】细节理解题。根据文章最后一段“To use this app, a person first acquires an image of someones face, from either the smartphones camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered infor
61、mation is displayed. The collected data are stored only on a users phone, according to the team behind the app.(要使用这款应用程序，用户首先要从智能手机的摄像头或照片上获取某人的面部图像，然后给它贴上一个名字。当摄像头在现实生活中发现同一张脸时，之前输入的信息就会显示出来。该应用程序的研发团队表示，收集到的数据只存储在用户的手机上)”可知，SocialRecall通过在识别人脸时显示此人的信息来帮助脸盲症患者。故选D。【30题详解】推理判断题。根据文章第四段中的“She cautio
62、ns, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you.”(然而，她警告说，当人们选择在这款应用上分享个人信息时，他们应该知道，“这些信息在另一种情况下使用，可能会
63、带来意想不到的后果，最终可能会反过来伤害到你。”)”可推知，SocialRecall这款应用程序可能会危及人们的隐私。故选A。DFollowing the outbreak of the novel coronavirus pneumonia (NCP), also named COVID-19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing the NCPs
64、 symptoms are similar to the common cold or the flu, but its potentially more dangerous.Viruses could be deadly, like HIV and Ebola. But what are viruses? How can they cause so much trouble?Viruses are non-living organisms (有机体) approximately one-millionth of an inch long. Unlike human cells or bact
65、eria, they cant reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.Viruses can infect every living thing from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human life. So
66、metimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger no noticeable reaction.Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once inside, the
67、y try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. “Tracing the origins of viruses is difficult”, Ed Rybicki, a virol
68、ogist (病毒学家) at the University of Cape Town in South Africa, told Scientific American, “because viruses dont leave fossils and because of the tricks they use to make copies of themselves within the cells theyve invaded”.However, there are three main hypotheses (假说) to explain the origin of viruses.
69、First, viruses started as independent organisms, then became parasites (寄生者). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.For the time being, these are only the
70、ories. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.31. What can we learn a
71、bout viruses from the text?A. Viruses have nothing to do with the common cold.B. Viruses are really small living organisms.C. Viruses cant reproduce unless they find a host cell.D. Viruses enter our bodies mainly through the mouth, nose and hair.32. Which of the following might explain the origin of
72、 viruses?A. They evolved from the fossils of large organisms.B. They evolved from parasites into independent organisms.C. They evolved from the T-cells in animals.D. They evolved along with their host cells.33. The underlined word “plausible” in the last paragraph probably means _.A. reasonableB. co
73、mmonC. creativeD. unbelievable34. What can we conclude from the text?A. Viruses live longer in human host cells than in animals.B. Viruses will become more like bacteria as they evolve.C. It may take a long time to understand the origin of viruses.D. The author is optimistic about future virus resea
74、rch.【答案】31. C 32. D 33. A 34. C【解析】【分析】本文是说明文。文章介绍了关于COVID-19新型冠状病毒肺炎的传播途径、病毒起源的研究情况。研究表明病毒自身无法传播，是通过宿主细胞来感染的；目前关于病毒起源的解释有三种主要的假说，但都还处于理论阶段。【31题详解】细节理解题。根据第三段中“Unlike human cells or bacteria, they cant reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread an
75、d take over. （与人类细胞或细菌不同，它们不能自己繁殖。相反，它们侵入生物体的细胞来繁殖、传播和接管）”可知，病毒自身不能繁殖，只有找到宿主细胞才能繁殖。故选C项。32题详解】细节理解题。第七段是关于病毒起源的三种假说。其中第三种假说是“Third, viruses co-evolved with their host cells, which means they existed alongside these cells.”可知，研究认为病毒与宿主细胞共同进化，并且与这些细胞共存。故选D项。【33题详解】词句猜测题。第七段中提到“there are three main hyp
76、otheses (假说) to explain the origin of viruses.”，以及第八段中“these are only theories”。可知，关于病毒的起源，现在都只是处于理论阶段。现在的技术和数据对于病毒的起源还无法作出“合理的”解释。因此可以猜测plausible意思为“合理的”。故选A项。【34题详解】推理判断题。根据最后一段中“Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含
77、糊不清的) than it now appears.（后续的研究可能会给我们提供更清晰的答案。或者未来的研究可能表明，答案甚至比现在看起来的还要含糊不清的。）”可以推断，要找到病毒的起源还需要很长一段时间。故选C项。第二节 （共 5 小题:每小题 2 分，共 10 分）根据短文内容，从短文后的七个选项中选出能填人空白处的最佳选项，选项中有两项为多余选项。Are you a bookworm?

The width
88、 of a cracker. Its also the amount that the Atlantic Ocean is expanding every year.Now when youre talking about an ocean that is 4,830 kilometres (3,000 miles) wide at its largest point, 4 centimetres (1.6 inches) is not much. But it is happening. So naturally, scientists want to know why.Thanks to
89、a new study, researchers think that they have the answer why. You could even call it a hot take. As in hot magma, or molten rock, deep under the ocean floor!The study suggests that the expansion is being caused by magma(岩浆) bubbling up from under an underwater mountain range called the Mid-Atlantic
90、Ridge. Lets start with what that ridge is.Basically, the Mid-Atlantic Ridge is the seam between some very large tectonic plates. The ridge is also known as a plate boundary. As weve discussed before here, tectonic plates are essentially the platforms that our continents rest on. They are large piece
91、s of the crust that are always moving in slow motion.This movement is what causes earthquakes, for example. And the areas where the plates meet are where we tend to find things like mountains and volcanos, as well.In this case, as the magma bubbles up from the mantle(地幔) below the crust, it is pushi
92、ng the edges of both plates out of the way. As a result, the ocean is slowly getting wider.This is a new finding. Before the study, scientists thought that the plates were being pulled apartthey were being dragged away from the ridge by forces occurring on either side of the ocean, not from in the m
93、iddle.Scientists still believe that this pulling motion is happening. It is just that now, they feel that the bubbling magma is an important force as well. There is push and pull.The scientists behind this study have been quick to point out that their research is only looking at a small cross-sectio

But it is still really useful informationand how they got it is pretty cool.Back in 2016, a research ship traveled to a very quiet spot directly over
95、the ridge. Over five weeks, the crew dropped 39 seismometers on to the ocean floor. These devices allow them to listen to the activity of the tectonic plates and what was beneath it. Its like what a stethoscope does with your heartbeat, but for the planet. A year later, they retrieved the devices an

102、e version)【解析】【分析】本文是一篇说明文。文章主要讲述一项新的研究揭示了地球第二大海洋为什么膨胀了的原因。【40题详解】考查细节理解。根据文章第五段“The study suggests that the expansion is being caused by magma(岩浆) bubbling up from under an underwater mountain range called the Mid-Atlantic Ridge. Lets start with what that ridge is.（这项研究表明，这种扩张是由海底“山脉”(即中大西洋脊)下涌出的岩浆
103、造成的。让我们从山脊开始。）”可知，这种扩张是由海底 (即中大西洋脊)下涌出的岩浆造成的。故答案为The expansion is being caused by magma bubbling up from under an underwater mountain range called the Mid-Atlantic Ridge.。【41题详解】考查词义猜测。根据上文“Basically, the Mid-Atlantic Ridge is the seam between some very large tectonic plates. The ridge is also known
104、 as a plate boundary. As weve discussed before here, tectonic plates are essentially the platforms that our continents rest on. They are large pieces of the crust that are always moving in slow motion. （基本上，中大西洋洋脊是一些非常大的构造板块之间的接缝。这个山脊也被称为板块边界。正如我们之前讨论过的，构造板块本质上是我们大陆所依托的平台。它们是地壳的大块，总是在缓慢移动。）”由此可推断这种运
105、动就是指板块的移动，故答案为The slow motion/movement of the crusts of the earth (tectonic plates).。【42题详解】考查细节理解。根据文章第五段“This is a new finding. Before the study, scientists thought that the plates were being pulled apartthey were being dragged away from the ridge by forces occurring on either side of the ocean, n
106、ot from in the middle.（这是一个新发现。在这项研究之前，科学家们认为板块是被拉扯开的它们被大洋两边的力量从洋脊上拖走，而不是被洋脊中间的力量拖走。）”由此可知科学家们仍然相信这种“拉”运动正在发生。只是现在，他们觉得沸腾的岩浆也是一股重要的力量。因此“Scientists find that it is the magma below the crust that is pushing the edges of both plates out of the way to cause the ocean to slowly get wider（科学家发现它是地壳下面的岩浆，
107、将这两个板块的边缘拉扯导致海洋慢慢宽）”这一部分是正确的；后半部分 “but not the forces occurring on either side of the ocean pulling the plates apart.（但不是海洋两侧的力量将板快分开。）”不符合文意，故答案为Scientists find that it is the magma below the crust that is pushing the edges of both plates out of the way to cause the ocean to slowly get wider, but n
108、ot the forces occurring on either side of the ocean pulling the plates apart. According to the passage, scientists still believe that this pulling motion is happening. It is just that now, they feel that the bubbling magma is an important force as well. There is push and pull.【43题详解】考查推理判断。根据文章最后一段“
109、Then it was back to the lab to try and piece together what they learned. In the end, they have added to our understanding of how and why the Earths surface constantly moves.（然后回到实验室尝试拼凑他们所学到的东西。最后，它们增加了我们对地球表面如何以及为什么不断移动的理解。）”由此可知这一发现对于科学家们研究地球科学有帮助意义，并且为以后地球的可持续发展作出贡献，故答案为In my opinion, this findin
