1．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year, it was revealed last night, according to The Daily Express.
The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen "at risk" patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: "I am so excited about this form of technology." Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. "I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a completely new example in the way we manage healthcare."
The technology is the brainchild of Dr Vishal Nangalia, a consultant at the Royal Free Hospital in London. He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 years. Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.
He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy. Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die. "This gives us the opportunity not only to save lives but to prevent serious illness, making the health service not only safer but more efficient." Prof Young said, "Instead of waiting for people to get worse, we will be able to treat them earlier."
（1）What does the underlined phrase "screen" in Paragraph2 mean?
A. comfort
B. treat
C. spot
D. nurse
（2）How do supercomputers help save lives?
A. By storing blood samples.
B. By analyzing patients' cases.
C. By observing changes in blood cells.
D. By assisting doctors with their operations.
（3）Why did Professor Young mention the Industrial Revolution?
A. To show the influence of AI.
B. To stress the importance of health care.
C. To introduce the topic of supercomputers.
D. To present the achievement he has accomplished.
（4）What do we know about the new technology?
A. It helps patients recover earlier.
B. It has helped save thousands of lives.
C. It will promote the health service greatly.
D. It is intended for patients with kidney diseases.
【答案】（1）C

2．犇犇阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.
For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.
Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.
After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.
They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to
disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
（1）How did the scientists conduct the experiment?
A.By leaving dogs to women who are either happy or angry.
B.By mixing the selected dogs together.
C.By rewarding only half of the dogs touching the screen
D.By showing digital pictures of women's happy or angry faces.
（2）The underlined word "trepidation" in Paragraph 5 probably means ________.
A.fear and hesitation
B.curiosity and eagerness
C.excitement and happiness
D.doubt and sadness
（3）According to the last paragraph, dogs with female owners ________.
A.are fond of the male faces
B.are uninterested in telling the emotions on the entire faces
C.have difficulty telling the moods on the faces of males
D.can only recognize emotions of females
（4）What is the best title for this passage?
A.Mood Changes Influence Dogs
B.Dogs Identify the Moods
C.dogs and Their Owners
D.Dog's Mood Research
【答案】（1）D
（2）A
（3）C
（4）B
【解析】【分析】本文是一篇说明文，最新的实验发现，即狗能够识别人的面部表情的变化。

（1）考查细节理解。

根据第二段中的"For their study biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy."可知，实验人员通过屏幕向这些狗展示了一组女性面部表情的照片，这些表情中既有快乐的，也有愤怒的。

故选D。

（2）考查词义猜测。

根据第五段中的"They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly"以及"However"可知，与前面意思相反，以及划线词后的"disappear"可知"once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear.…"此句为，狗看到生气的表情后会感到厌恶，并由此退缩，
但是一旦聪明的狗意识到会有奖励之后，它们的恐惧以及退缩就会消失。

由此可判断出A 符合题意，故选A。

（3）考查推理判断。

根据最后一段中的"......this confirmed what had been observed in previous studies―dogs are more efficient at reading facial expressions of people that are the same gender as their owner"可知，狗擅长辨别与自己主人性别相同的人的表情，由此推断，让主人是女性的狗来辨别男性面部表情的图片是比较困难的。

故选C。

（4）考查主旨大意。

第一段提出文章的主旨即“每个狗的主人都知道他们的狗狗能很好地读懂他们的情绪，但科学家们一直有点怀疑。

现在，有证据表明这是正确的”，接着在下文用硬实证明了这一点。

因此本文的最好的题目就是“狗能识别人的情绪”。

故选B。

3．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

When hospital staff are in full scrubs (手术衣), their faces are almost completely covered by their caps and face masks, and we can only see their eyes and eyebrows. In order to solve the problem, a doctor in Sydney, Australia, called Rob Hackett launched a campaign named "Theatre (手术室) Cap Challenge"-encourage hospital staffs to write their' names and roles on their caps. At first, his colleagues didn't take it seriously. However, with time going on, it has been adopted around the world with studies from the US and UK reporting how this simple idea can decrease human errors in healthcare.
"I went to a theatre where there were about 20 doctors and nurses in the room," Dr. Rob Hackett said. "I struggled to even ask to be passed some gloves because the person I was pointing to thought I was pointing to the person behind them, because I don't know their names." said Rob. As we all know, doctors are a stressful profession. When faced with life and death, they need to save the patient's life for a second. At the moment, effective communications are important.
"The 'Theatre Cap Challenge' is in response to concerns about how easily avoidable mistakes and poor communication are contributing to rising harmful events for our patients." said Rob. "We need to develop systems which reduce mistakes and misunderstanding without causing harm. For this to happen, we need to let everyone know we're human." he added On the other hand, from the patients' viewpoint, caps with names on them can make patients more unworried. When everyone appears the same, it is extremely difficult to distinguish who is who. Knowing them relaxed.
（1）What can we learn from paragraph 1?
A. Hospital staff are asked to cover their faces in hospitals.
B. Rob is in favor of writing names and roles on caps.
C. Rob wanted to be a professional doctor.
D. Rob's idea can increase human errors in healthcare.
（2）What can we know about the "Theatre Cap Challenge" from the text?
A. It can make the caps more fashionable.
B. It is strongly opposed to by all the doctors and nurses.
C. It aims to avoid mistakes and poor communication.
D. It can help people pass some gloves in a theatre.
（3）Which of the following best explains "were human" underlined in paragraph3?
A. We're generous.
B. We're negative.
C. We're satisfied.
D. We're kind.（4）What's the patients' attitude towards the campaign?
A. Supportive
B. Disapproving
C. Doubtful
D. Uncaring
【答案】（1）B
（2）C
（3）D
（4）A
【解析】【分析】本文是一篇说明文，在手术室里，医生和护士都戴着手术帽和口罩，只露出眼睛和眉毛，这让周围的人认不出他们，导致在交流过程中产生误会。

于是，一位澳大利亚的医生Rob提出在手术帽上写上名字和职位，这一想法逐渐得到了全世界很多国家的认可。

（1）考查推理判断。

根据第一段中的“In order to solve the problem, a doctor in Sydney, Australia, called Rob Hackett l aunched a campaign name‘"Theatre (手术室) Cap Challenge’-encourage hospital staffs to write their' names and roles on their caps.”Rob提出在手术帽上写上名字和职位，由此可知他是支持这一想法的。

故选B。

（2）考查推理判断。

根据第二段中的例子和第三段中的"The 'Theatre Cap Challenge' is in response to concerns about how easily avoidable mistakes and poor communication are contributing to rising harmful events for our patients. "可知，Theatre Cap challenge活动是为了应对不断增加的病患相关不良事件，而这些事件常是由一些很容易避免的错误和沟通障碍引起的。

所以这项活动目的是尽量避免错误和交流中的误解。

故选C。

（3）考查词义猜测。

根据第三段中的“ We need to develop systems which reduce mistakes and misunderstanding without causing harm.”可知,他们想建立一种在不造成伤害的情况下尽可能减少错误和误解的系统，而要达到这个目的，首先要让每个人知道医生是人类，是有人情味的。

只有病人也感觉到医生的善良，才能减少病患之间的误解。

故选D。

（4）考查观点态度。

全文最后三句是站在患者角度阐述这个活动的意义。

从其中的"unworried（不担心的，不着急的）"和"relaxed（松懈的，放松的）"两个词可以知道，这个活动能让病人心情放松，病人对这一做法是很支持的。

故选A。

【点评】本题考点涉及推理判断，词义猜测和观点态度三个题型的考查，是一篇科教类阅读，要求考生根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。

4．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

Boomerang children who return to live with their parents after university can be good for families, leading to closer, more supportive relationships and increased contact between the generations, a study has found.
The findings contradict research published earlier this year showing that returning adult children trigger a significant decline in their parents' quality of life and wellbeing.
The young adults taking part in the study were "more positive than might have been expected about moving back home—the shame is reduced as so many of their peers are in the same position, and they acknowledged the benefits of their parents' financial and emotional support. Daughters were happier than sons, often slipping back easily into teenage patterns of behaviour, the study found.
Parents on the whole were more uncertain, expressing concern about the likely duration of the arrangement and how to manage it. But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities.
The families featured in the study were middle-class and tended to view the achievement of adult independence for their children as a "family project". Parents accepted that their children required support as university students and then as graduates returning home, as they tried to find jobs paying enough to enable them to move out and get on the housing ladder. "However", the study says, "day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates".
Areas of disagreement included chores, money and social life. While parents were keen to help, they also wanted different relationships from those they had with their own parents, and continuing to support their adult children allowed them to remain close.
（1）What is the finding of the previous research?
A. Boomerang children made their parents happier.
B. The parents were looking forward to their children's return.
C. The parents' quality of life became worse than before.
D. Boomerang children never did any housework.
（2）The underlined word "trigger" in Paragraph 2 may be best replaced by ________. A. cause B. defeat C. arise D. allow
（3）What is the attitude of the college graduates towards returning home?
A. They are ashamed of turning to their parents for help.
B. They are glad that they could come back.
C. They are doubtful about whether they should return.
D. They are proud to be independent from the family.
（4）What can be inferred as the reason for the "boomerang children" phenomenon?
A. The children want to keep in closer touch with their parents.
B. The parents are willing to provide support to their children.
C. It is harder for the children to secure a satisfying job.
D. There is more house work needed to be done by the children.
（5）What is the side effect of the boomerang children phenomenon?
A. Both parents and children enjoy a more harmonious relationship.
B. Neither parents nor children want to do the chores at home.
C. Not only parents but also children want to be independent.
D. There are occasional quarrels between parents and children.
【答案】（1）C
（2）A
（3）B
（4）C
（5）D
【解析】【分析】本文是一篇说明文，一项研究发现，“回巢族”子女在大学毕业后回到父母身边生活对家庭是有好处的，他们会与父母建立更亲密、更具支持性的关系，并增进两代人之间的联系。

而这一发现与今年早些时候发表的一项研究结果相矛盾，该研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著下降。

父母和孩子对于独立的紧张情绪会导致父母和子女之间偶尔的争吵。

（1）考查推理判断。

根据第二段中的“The findings disagree with the research published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing.”这一发现与今年早些时候发表的一项研究结果不一致，早些的研究显示，返乡的成年子女会导致父母的生活质量和幸福感显著恶化。

可知，以往的研究显示，返乡的成年子女会导致父母的生活质量和幸福感比之前更差，故选C。

（2）考查词义猜测。

根据第二段中的“The findings disagree with the r esearch published earlier this year showing that returning adult children trigger a significant worsening in their parents' quality of life and wellbeing. ”通过新旧研究对比，以往的研究表明，返乡的成年子女会导致父母的生活质量和幸福感显著下降。

即可推理划线部分单词trigger意为“导致，致使”，与cause意义一致。

故选A。

（3）考查细节理解。

根据第三段中的“The young adults taking part in the study were‘more positive than might have been expected’about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their parents' financi al and emotional support.”参与这项研究的年轻人对于搬回家“比预期的更积极”——他们的羞愧感减少了，因为他们的许多朋友都处于同样的处境，而且他们承认父母在经济和情感上的支持是有好处的。

）可知，大学毕业生对回家的态度是积极的，很高兴能够回家，故选B。

（4）考查推理判断。

根据第四段中的“But they acknowledged that things were different for
graduates today, who leave university with huge debts and fewer job opportunities.”但他们承认，如今的毕业生情况有所不同，他们毕业时背负着巨额债务，工作机会也更少。

由此推断出，孩子们很难找到一份满意的工作，故选C。

（5）考查细节理解。

根据倒数第二段中的"‘However’, the study says, ‘day-to-day tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict”可知对于实现不同层面独立前景的日常紧张情绪，是大多数家长和略多于一半毕业生经历的特征。

在少数极端情况下，这种紧张情绪接近冲突。

可知回巢族孩子现象的副作用是在少数情况下，紧张情绪会导致父母和孩子之间偶尔发生争吵。

故选D。

5．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.
A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only one-twelfth of a tea spoon of me.
The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.
Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return.
（1）What does "me" refer to in the passage?
A. The flower
B. The bee
C. Water
D. Honey
（2）What is the 2nd paragraph mainly about?
A. Bees' special talent
B. Bees' hard work.
C. Bees' living environment.
D. Bees' social behavior.
（3）What is the purpose of the passage?
A. To appeal for help for honeybees.
B. To talk about the history of a treasure.
C. To put forward techniques for gardeners.
D. To argue against the control of chemicals.
【答案】（1）D
（2）B
（3）A

6．犇犇阅读理解
A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.
Shining iridescent color, which changes depending on the angle from which it's viewed, is favored by everything from birds to beetles and blossoms to butterflies.
"And in our research group we are of course interested in why this vivid metallic color is so widespread in nature." Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. " Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates." But iridescence also shows up in situations where reproduction is not an issue. " So what we are studying now is whether natural selection imposed by predation(捕食行为) could explain the occurrence of iridescence in prey animals."
The idea that eye-catching colors could be used as a cover-up isn't a new one." The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing-Coloration in the Animal Kingdom, already in 1909, that 'brilliantly changeable or metallic colors are among the strongest factors in an animal's concealment'. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal's
concealment？"
"In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition." Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. "It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish." As for making use of this method for hiding in plain sight, "Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize." The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird's-eye view.
（1）According to the passage, iridescence is not made use of by animals to ________. A. live a little longer by escaping their predator(捕食者) B. catch the attention of their mates C. conceal themselves when in danger D. catch sight of more colorful preys （2）From the study in the last paragraph, we can learn that ________.
A. Bees can always tell the difference between a circle and an oval
B. Bees are creatures that are fascinated by sweet things that are iridescent
C. If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding it
D. Bees are likely to prefer circles to ovals, whether they are iridescent or not
（3）What will be talked about in the following paragraph?
A. Whether there are any differences between bees and birds.
B. Some industries that have great interest in camouflage.
C. Why birds are not effected by iridescent insects.
D. Which camouflage theory applies more to birds.
（4）Which of the following might serve as the best title of the passage?
A. A famous camouflage strategy
B. Metallic iridescent as the best disguise
C. Colors unique to animals
D. Shining colors as a sexual strategy
【答案】（1）D
（2）C
（3）C
（4）B
【解析】【分析】本文是一篇说明文，介绍了彩虹色有助于生物隐藏。

（1）考查细节理解。

根据第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被动物用来通过逃离捕食者而活得更久，排除A；根据第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在这里我想指出的是，在某些物种中，尤其是那些表现出强烈两性差异的物种，比如天堂鸟、孔雀，甚至在某些蝴蝶
或鱼类中，彩虹色的出现很可能是由性别选择所驱动的。

可知动物用彩虹色引起同伴的注意，排除B；根据倒数第二段中的“The idea that eye­catching colors could be used as a cover­up isn't a new one.”引人注目的颜色可以用来伪装，这种想法并不新鲜，排除C，故选D。

（2）考查细节理解。

根据最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我们的目标上惊人的彩虹表面在视觉上打破了原本可以辨认的目标形状，这使得它们很难区分。

故选C。

（3）考查推理判断。

根据最后一段说研究人员目前正在对鸟类进行实验，这些鸟类的饮食中经常含有彩虹色的昆虫。

实验目的是看看鸟类的视角是否能提供帮助。

由此推断接下来一段会谈论为什么鸟类不受彩虹色昆虫的影响，故选C。

（4）考查主旨大意。

第一段中的“Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle p redators, which allows colorful prey to survive another day.”有时，最好的伪装其实是最耀眼的伪装，因为研究表明，闪光的金属彩虹色能在视觉上迷惑捕食者，这让五颜六色的猎物能够再存活一天，是全文的主题句，结合全文内容，可知这篇文章主要讲了彩虹色有助于生物隐藏，故选B。

7．阅读理解
A new study suggests a link between exposure to greenery and reduced desires for alcohol cigarette and junk food.
The study is the first to investigate the possible relationships between exposure to nature and desires and negative emotions. Researchers at the University of Plymouth's School of Psychology surveyed 149 respondents (应答者) aged 21 o 65 about the proportion( 比例 )of green space in their neighborhood, the presence of green views from their home, their access to a garden and how often they use public green space. The study also asked questions about experiences with depression and anxiety, as well as desires for things like caffeine, alcohol and nicotine. Participants rated the intensity( 强度), imagery, and intrusiveness(侵扰性) of their desires on an 11-point scale.
Researchers found the presence of visible green space contributed to decreased desires for junk food. The effect was particularly noticeable when more than 25 percent of a respondent's view was greenery.
Previous scholarship(学术研究) has dealt mostly with exercise in nature: A 2015 study out of the University of Michigan found 90- minute group nature walks were effective at combatting depression and relieving other mood disorders. But for people who struggle with accessibility or don't have time for a 90-minute walk, this new study suggests just looking out a window at a tree can help fight off a bad habit.
"It has been known for some time that being outdoors in nature is linked to a person's well-being," lead author Leanne Martin said in a statement." But for there to be a similar association with desires from simply being able to see green space adds a new dimension to the previous research."
A 2018 study from Denmark's Aarhus University for example, found that. Having access to green space throughout childhood decreased a person's risk of developing mental health problems as an adult.
（1）What does the second paragraph mainly talk about?
A.The results of the new study.
B.The purpose of the new study.
C.The significance of the new study.
D.The content of the new study.
（2）What does the underlined word "combatting" in paragraph 4 probably mean?
A.Reducing.
B.Developing.
C.Understanding.
D.Encouraging
（3）According to the passage, the new study _____.
A.mainly referred to exercise in nature
B.has enriched the previous research to some degree
C.was carried out by the University of Michigan
D.found exposure to greenery helped cure mental problems
（4）n which section of a newspaper may this passage appear?
A.Entertainment
B.Business World
C.Tech &Science
D.Environment
【答案】（1）D
（2）A
