26、believe that they are either born with a talent for something or they dont have it completely. What can they do?Some answers come from the work of Paul OKeefe.

27、he capacity to cultivate new interests outside their normal fields. _15_ (consider) arts students looking at a piece about science, or “techy” students reading an article on literary criticism(文学评论). _16_ the students have very little initial curiosity about the subject, with the growth mindset, the

29、 about black holes, people had to read a challenging academic paper on the subject.

32、考查时态。句意：在过去的十年里，研究人员已经证明，有些人倾向于把自己的能力视为“固定的”他们认为自己要么天生就有某种天赋，要么根本就没有这种天赋。根据“In the past ten years ”可知，本句为现在完成时，主语为the researcher，助动词用has。 故填has demonstrated。【14题详解】考查连接词。句意：在他的心态理论中，激情的最基本的基础是对你正在做的事情产生强烈的兴趣。in后接宾语从句, 从句缺少主语，再结合句意可知，空处填连接词whatever/what。 故填whatever/what。【15题详解】考查祈使句。句意：思考一下正在看一篇关于科学的

34、ther“是否”。故填whether。【18题详解】考查动名词。句意：在一个实验中，在播放了一段关于黑洞的视频后，人们必须阅读一篇关于这个主题的具有挑战性的学术论文。after为介词后接动名词,且people与show在逻辑上是被动关系。故填being shown。【19题详解】考查形容词比较级。句意：具有成长思维的人保持着他们的兴趣：尽管很难掌握技术资料，但他们更愿意了解黑洞。根据句意表示“他们更愿意了解黑洞 ”，所以空处填比较级more willing。故填more willing。【20题详解】考查介词。句意：奥基夫说：“在七分钟的时间里，他们从说“这很有趣”变成了说“不，我看不懂”。f

37、 the 39-year-old man became an internet celebrity.

38、n of American artist Andy Warhols work in Stockholm. This prediction has, in many respects, come true in an era when there are so many channels by which an individual might _23_ fame (although it is the type of fame which may not endure for very long). You could be one post away from becoming the ne

39、xt celebrity. Sometimes this fame can open doors to other opportunities, but sometimes it can be cruel and frightening.Unlike Cheng and his _24_ fame, more people are using online platforms such as Weibo and Bilibili to become “intentional” celebrities.

47、：与程云福偶然成名不同，越来越多的人通过微博、哔哩哔哩等网络平台成为“有意”名人。根据unlike和intentional可知，此处是指程云福的偶然成名。所以应用形容词accidental表示“偶然的”作定语修饰名词fame。故选J。【25题详解】考查副词。句意：KOL通常是“在特定领域拥有专业产品知识和影响力”的人。根据后文“He or she is “trusted by relevant groups” and has “a significant effect on consumer behavior.”(他或她“受到相关群体的信任”，“对消费者行为有显著影响”。)可知，此处是指KOL

48、通常是“在特定领域拥有专业产品知识和影响力”的人。所以应用副词typically表示“通常”修饰be动词作状语。故选B。【26题详解】考查名词。句意：说到网红，Papi酱和李子柒只是少数，因为成功比乍看起来要难得多。根据“as success is much harder to achieve than it would appear at first glance”可知，Papi酱和李子柒只是少数。所以应用名词minority表示“少数”作介词in的宾语。故选C。【27题详解】考查形容词。句意：你必须知识渊博和有趣，并有能力制作高质量的视频，并定期发布新的。根据“You have to be

Reading Directions: Read the following three passages. Each pa

67、ssage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D.

68、gnal that is bounced（反弹） or “echoed” off the sea floor and then recorded on board the ship. The speed of sound in water is 1,500m per second, four times faster than the speed of sound in air. By carefully measuring the round-trip time of the sound waves and taking into account the variables of tempe

69、rature and salinity （盐度）, the depth of the water and the distance to another object can be measured accurately.Taking soundings this way is time-consuming, especially in deep water. Today most depth measurements are made using an echo sounder. Instead of dropping a weight, a pulse （脉冲） of sound ener

70、gy is transmitted （发射） electronically toward the bottom. The time it takes the pulse to travel to the bottom and be reflected back up to the surface is measured. From this time interval （间隔）, the depth of the water can be calculated. When pulses are sent out and received in quick speed, an almost co

71、ntinuous recording of the ocean depth called a bottom profile may be obtained.The sedimentary rocks （沉积岩） that exist on the ocean bottom are much younger than any similar rocks found on the continents. The central part of mud and rock brought back by deep-sea drilling ships vary greatly in age, but
