There was a lt f news related t artificial intelligence, r AI, and machine learning. Amng the stries were tw dealing with direct cmpetitins between humans and machines.
In ne cmpetitin, machines that used AI perfrmed better than human beings in a high-level reading test. Tw natural language prcessing tls beat human in the experiment. One f the tls was built by the American technlgy cmpany Micrsft. The ther was created by Chinese nline seller Alibaba Grup.
In anther cmpetitin, a cmputer tk n humans in live, public debates. The event demnstrated hw AI-pwered cmputers are increasingly being develped t think and sund like humans. The rganizer f the debates, US technlgy cmpany IBM, annunced split results. It said a majrity f thse watching said they felt the machine had dne mre t imprve their knwledge f the subject. But, the human gt mre praise fr cmmunicating their ideas.
This year, we als explred the many ways AI and machine learning are nw being used. Fr example, sme US judges use machine learning systems t help them decide when, and fr hw lng, criminals shuld be jailed. The system uses cmputers t examine data frm thusands f curt cases.
One fast-grwing area f AI is facial recgnitin, which is increasingly being used fr security purpses. Recently, Atlanta's Hartsfield-Jacksn airprt became the first in the US t permit passengers t use facial recgnitin technlgy t get n flights. A Chinese cmpany shwed an AI system develped t recgnize individuals by bdy shape and walking mvements. The system is already being used by Chinese plice in Beijing and Shanghai.

While every dg wner knws their dgs can read their mds perfectly, scientists have always been a little dubtful. Nw thanks t sme researchers at the University f Veterinary Medicine in Vienna, Austria, we finally have sme cnvincing evidence.
Fr their study, bilgist Crsin Müller and his team expsed eleven selected dgs t digital images f wmen that were either angry r happy. Half the dgs were rewarded fr tuching the screen when shwn a happy face, while the ther half gt their treat fr selecting thse that appeared angry.
Interestingly, the dgs were nt prvided with the entire face. Sme dgs were shwn nly upper halves while the thers bserved lwer halves. That's because the scientists believe humans shw their emtins n their entire face.
After sme training like hw t recgnize small differences like the wrinkles between the eyes r the changes in their shape that accmpany the happy r angry expressins, the dgs were mstly able t identify the crrect expressin nt nly n a familiar face but n a strange face. The researchers cncluded the dgs were smart enugh t read human emtins.
They als fund thse being trained t read angry expressins tk a lnger time t learn. They guess it may be because dgs find angry faces disgusting, causing them t withdraw quickly. Hwever, nce the smart dgs realized they were getting rewarded, the trepidatin seemed t disappear. In fact, the dgs had such a gd time playing the cmputer “game” that scientists had a hard time keeping them away frm the tuch screens after the study was cmpleted.
The researchers als nticed nly dgs with a male wner had a harder time understanding the expressins crrectly. Since the tuchscreen mdels were all females, this cnfirmed what has been bserved in previus dg studies—dgs are mre efficient at reading facial expressins f peple that are the same gender as their wner.
1.Hw did the scientists cnduct the experiment?
A. By leaving dgs t wmen wh are either happy r angry.
B. By mixing the selected dgs tgether.
C. By rewarding nly half f the dgs tuching the screen.
D. By shwing digital pictures f wmen's happy r angry faces.
2.Which f the fllwing statements is TRUE?
A. The dgs were nt all prvided with the entire face.
B. Accrding t their size, the dgs were given either upper r lwer halves.
C. The dgs culd read even small changes that accmpany facial expressins after sme training.
D. The dgs culdn't read strangers facial emtins.
3.The underlined wrd “trepidatin” in Paragraph 5 prbably means _____.
A. hrrr B. curisity C. excitement D. dubt
4.Hw might the results change if the dgs with female wners are shwn pictures f male faces?
A. They culd nly tell emtins n partial faces rather than n entire faces.
B. They fund it hard t tell the mds n the faces f a different gender.
C. They fund it easy t tell the emtins n the entire face.
D. They wuld be scared away at the sight f the pictures.

The study als shwed that men and wmen have similar feeling patterns as they grw lder.
Hwever, wmen at all ages reprted mre sadness, stress and wrry than men.
Researchers say they d nt knw why happiness increases as peple get lder. One thery is that, as peple grw lder, they grw mre thankful fr what they have and have better cntrl f their feelings. They s spend less time thinking abut bad experiences.
Prfessr Stne says the emtinal patterns culd be cnnected t changes in hw peple see the wrld, r maybe even changes in brain chemistry.

【点评】考查七选五，本文是一篇故事类阅读，要求在理解细节信息的基础上，着重考查对上下文的理解和推理判断能力。
36.根据空前“I experienced an earthquake with my friend and clleague Dawa Chhiri Sherpa last Saturday.”上周六，我和我的朋友兼同事Dawa Chhiri Sherpa一起经历了一次地震；以及空后“But we were lucky enugh t survive it.”但我们很幸运能活下来。可知，上文提到作者和同事经历了一次地震，后文提到他们活了下来，可推测本句承接上文说明对地震的感受。B. It was a hrrible experience.“这是一次可怕的经历”符合语境，故选B。
37.根据空前“It was quite a usual mrning at first. That mrning, Dawa and I had breakfast ut with his sn Snam.”起初，这是一个很平常的早晨。那天早上，Dawa和我和他的儿子Snam一起出去吃早餐，可知，上文提到了作者他们在吃早餐，故本句应承接上文说明早饭之后他们的活动，F选项中breakfast对应上文中breakfast。F. After breakfast, Dawa tk me back t my htel.“早饭后，Dawa送我回旅馆”符合语境，故选F。
38.根据空前“We managed t slwly make ur way t pen grund and struggled t even stand at times. There was a mment when I felt the htel and all the buildings wuld cme dwn, but they didn't.”我们设法慢慢地向开阔地前进，有时甚至要挣扎着站起来。有那么一刻，我觉得酒店和所有的建筑都会倒塌，但它们没有；以及空后“I wanted t find them.”我想要找到他们，可知，后文提到了作者想要找到某些人，可知本句应是在具体说明找到谁，后文them指代G选项中Dawa and his sn。G. After the first shck I became wrried abut Dawa and his sn.“第一次地震之后，我开始担心Dawa和他的儿子”符合语境，故选G。
39.根据上文“Sadly, just walking in that area was a challenge. The street was blcked.”遗憾的是，光是在那个区域行走就是一个挑战。街道被封锁了；以及空后“After walking arund the area fr 45 minutes I decided t make my way back t the htel. I waited n the pen grund at the htel. Luckily, I gt a call frm Dawa, saying they were safe. Fur hurs after the first earthquake, they gt back t the htel.”在附近走了45分钟后，我决定回到酒店。 我在旅馆的空地上等着。幸运的是，我接到了Dawa的电话，说他们很安全。第一次地震发生四小时后，他们回到了酒店。可知，上文提到街道封锁了，后文提到第一次地震发生四小时后，Dawa他们回到了酒店，可推测作者一开始在街道上没有找到Dawa或Snam。D. There was n sign f Dawa r Snam.“没有Dawa或Snam的迹象”符合语境，故选D。
40.根据空后“The first fur days after the earthquake were bad —n water, fd, electricity r infrmatin, as every three hurs we wuld be rcked by tremrs. By Wednesday, things were starting t g well. Dawa and I decided t g ut and help peple. And we did that n the fllwing three days as well.”地震后的头四天很糟糕，没有水，没有食物，没有电，也没有信息，因为每三个小时我们都会被余震震动。到周三，事情开始进展顺利。Dawa和我决定出去帮助别人。 我们在接下来的三天里也这样做了。可知，本段主要是在描述地震之后的生活艰难，C选项中after the earthquake对应后文中after the earthquake。C. Life after the earthquake was terrible.“地震后的生活很可怕”符合语境，故选C。

V. 语法填空.
【答案】 taking；little；aged；ut；appears；surveyed；injury/injuries；which；average；high；t have；achieved；in；wh/that；prbably
【解析】本文是一篇说明文，新的研究表明和运动太少的效果一样，青少年运动太多也会对他们的健康产生消极影响。每周大约14小时的体育运动，健康得分最高，但是超过14小时的体育运动健康得分较低。
（1）考查非谓语动词。句意：青少年一直被告知积极参加体育活动对他们的健康有好处。 and 为并列连词，根据前文的 being，所以后面 take 也用 ding 的形式。故填 taking .
（2）考查形容词。句意：新的研究表明和和运动太少的效果一样，青少年运动太多也会对他们的健康产生消极影响。little修饰不可数名词sprt 。t much与t little相对应。故填 little .
（3）考查形容词。句意：美国卫生与公众服务部建议6至17岁的年轻人每天至少锻炼60分钟，每周7小时。aged为过去分词作形容词作后置定语修饰 peple。故填aged .
（4）考查副词。句意：美国卫生与公众服务部建议6至17岁的年轻人每天至少锻炼60分钟，每周7小时。wrk ut 表示外出锻炼的意思。符合句意。故填ut .
（5）考查主谓一致。句意：然而，超过14个小时似乎对他们的健康有害。分析句子可知，本句为一般现在时，主语为14 hurs 是一个整体，所以谓语动词是单数appears 。故填appears .
（6）考查非谓语动词。句意：为了得出他们的研究结果，研究人员对1245名青少年进行了调查。分析句子可知，本句涉及have sth/sb dne的用法。 teenagers在逻辑上与survey在逻辑上是被动关系，且作teenagers的宾语补足语。所以用过去分词，填surveyed。
（7）考查名词。句意：所有参与者都被要求回答有关身高、体重、体育锻炼、运动伤害和健康的问题。根据逗号和 and 并列可知，都是相同的词性，为名词，injure 的名词形式为injury/injuries。sprts为名词修饰名词injury/injuries。故填injury/injuries.
（8）考查定语从句。句意：他们的健康是用“世卫组织健康指数”这个词来衡量的，该指数的得分在0到25之间。分析句子可知，Wrd Health Organizatin (WHO) Well-being Index为先行词，在后面的非限制性定语从句中作主语，所以关系代词为which。故填which .
（9）考查名词。句意：所有参与者的总体平均健康得分为17分。 verall为形容词修饰名词average且符合句意。故填average.
（10）考查形容词。句意：研究人员将运动参与者分为低、平均、高和非常高四类。由前文的 lw/average/very high，可知中间是高。故填high .
（11）考查非谓语动词。句意：研究人员发现，与平均水平组的参与者相比，低活动组和高活动组的参与者的健康得分更可能低于13分。be mre likely t d固定短语，“很有可能做某事”，故填t have。
（12）考查时态语态。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。研究表明最高的健康值达到，表示达到用 achieve，并且与主语the highest well-being scres是被动，所以用achieved。故填 achieved .
（13）考查介词。句意：研究人员发现，每周进行14小时体育活动的参与者的健康得分最高，但超过14小时的参与者的健康得分较低。result in “导致”符合句意。故填in .
（14）考查定语从句。句意：研究人员建议，关心青少年的医生应该检查他们的体育锻炼水平。dctrs为先行词在后面的定语从句中作主语，所以关系代词为wh/that。故填 wh/that .
（15）考查副词。句意：青少年可能需要更紧密地跟踪他们的健康状况。prbably为副词修饰动词need。故填prbably.
【点评】本题考点涉及非谓语动词，形容词，副词，主谓一致，名词，定语从句，时态语态以及介词等多个知识点的考查，是一篇健康类阅读，要求考生在理解细节信息的基础上，进一步根据上下文的逻辑关系，并结合相关语法知识，进行分析推理，从而写出正确的单词形式。

【解析】本文是一篇记叙文，讲述作者当老师的经历。作者作为志愿者去农村当老师．当作者看到孩子们时，他们给了作者最热烈的欢迎，作者很喜欢作他们的老师，尽力教他们，与他们的一起玩游戏等。
（1）考查时态。句意：上周，我很荣幸地体验了教学。根据时间状语last week，可知谓语动词用一般过去时，故have 改为had。
（2）考查名词。vlunteer是可数名词，其前有sme修饰时要用复数形式，故vlunteer改为vlunteers 。
（3）考查定语从句。分析句子结构可知这是一个限制性定语从句，先行词kids在从句中作主语，用关系代词wh/that，故which改为wh/that 。
（4）考查形容词。句意：当我见到那些孩子时，看到我他们那么高兴，认真听我说。be动词后用形容词作表语，故happily改为happy 。
（5）考查副词。句意：受到他们最热烈的欢迎，我很高兴成为他们的老师。因此我尽力教他们，和他们一起玩游戏。后一句是前一句的结果，用副词therefre，故Hwever改为Therefre 。
（6）考查代词。句意：回到学校，我非常想念我的学生。此处指作者的学生，故ur改为my。7
（7）考查连词。句意：他们很喜欢我，有些人甚至和我保持联系。前后句是顺承关系，不是转折关系，因此but改为and。
（8）考查冠词。keep in tuch with固定短语，“与保持联系”，故去掉in后的the。
（9）考查介词。句意：作为一个老师，我感到非常自豪。be prud f固定短语，“为感到骄傲”，故在prud后加f。
（10） 考查非谓语动词。make up ne's mind t d sth．固定短语，"下定决心做某事"，后接动词不定式，故realizing改为realize。
【点评】本题考点涉及时态，名词，定语从句，形容词，副词，代词，连词，冠词，介词以及非谓语动词等多个知识点的考查，是一篇故事类阅读，覆盖面广，综合性强，难度较大，区分度高。
