2．阅读理解
In 1953, a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest (珠穆朗玛). It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模拟)10w-, medium-, and high-altitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.
Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that bar-headed geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds.
The wind tunnel experiments showed that when the concentration of oxygen was at its lowest-like the 7% found on top of Mount Everest versus 21% at sea level—the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their blood-the measured blood temperature dropped so it could take in more oxygen, the researchers report today in eLife. This cooling likely helps compensate for the very thin air, the team says.
Although well trained, the birds were only willing to stay in the air a few minutes-or less when wearing their backpacks and flying at 6ihigh" altitudes. So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.（1）Why did the researchers raise 19 bar-headed geese and train them?
A. To test the flying height and speed of them.
B. To confirm they could fly over Mount Everest.
C. To observe them flying through the wind tunnel.
D. To see how many calories they burned per hour.
（2）What can we learn from the wind tunnel experiment?
A. It was carried out at very high altitude.
B. The geese managed to breathe less when their blood decreased.
C. The geese could live through the lowest concentration of oxygen.
D. It shows the geese could fly at high altitude for long.
（3）What still puzzles scientists about the geese?
A. Whether they have super hearts and lungs.
B. Whether they have muscles pumped more oxygen to.
C. Whether they are willing to wear backpacks and face masks.
D. Whether they can manage to fly 8 hours to climb over Mount Everest.
（4）Where does the text most probably come from?
A. A science fiction.
B. A climbing guide.
C. A travel brochure.
D. A science report.

【解析】【分析】本文是一篇说明文，登山者报告说看到一只长颈鹅翱翔在珠穆朗玛峰的顶峰，为了确认其真实性，研究人员养了18只这种鹅，在大型风洞中训练它们飞行。

结果发现这种鹅可以在氧气极低的情况下飞行，但停留时间只有几分钟，因此能否飞过珠峰尚不明确。

（1）考查推理判断。

根据第一段中的"In 1953, a mountain climber reported seeing a bar-headed goose soar over the peak of Mount Everest. It was thought impossible." 报道说，一名登山者看到一只斑头鹅飞过珠穆朗玛峰。

人们认为这是不可能的；以及" Now researchers who raised 19 of the geese-named for the black stripes on the backs of their heads-have shown the birds really fly so high."现在研究人员饲养了这种鹅，他们发现这些鹅真的飞得很高。

再根据最后一段中的"So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest."但是否能让这种鹅飞8小时爬上珠穆朗玛峰尚不清楚。

由此可推断出研究人员饲养这种鹅是为了证实这种鹅是否能飞过珠峰。

故选B。

（2）考查推理判断。

根据第四段中的"The wind tunnel experiments showed that when the concentration of oxygen ...the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped....the researchers report today in elife. This cooling likely helps comp"可知风洞实验表明，当氧气浓度最低时，鹅的心率和翅膀搏动频率保持不变，即使它们的新陈代谢率下降。

研究人员今天在《伊利费》杂志上报道说，...这种降温可能有助于补偿空气的稀薄；第五段中的"Although well trained, the birds were only willing to stay in the air a few minutes-or less ..." 尽管训练有素，但这些鸟只愿意在空中呆上几分钟。

这两处综合推断出，鹅可以在最低浓度的氧气中生存。

故选C。

（3）考查推理判断。

根据最后一段中的"So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest." 可知，目前尚不清楚的是，只有这些适应性变化能否可以飞行8小时爬上珠穆朗玛峰。

故选D。

（4）考查推理判断。

第一段中提到登山者报告说看到一只长颈鹅翱翔在珠穆朗玛峰的顶峰。

为了证实是否可能，研究人员养了18只这种鹅，并在大型风洞中训练它们飞行。

结果发现这种鹅可以在氧气极低的情况下飞行，但停留时间只有几分钟，因此能否飞过珠峰尚
不明确。

由此可知本文属于科普文章。

故选D。

3．阅读理解
A few years back I worked in a university building that also housed a department full of psychologists, all of whom seemed to see us as perfect guinea pigs(豚鼠) for their latest theories. If an eager graduate student showed up in my office bearing desserts and asked me to pick one, I'd cast a careful glance and ask "Why?" before grabbing the apple pie.
So one day, when someone from the Psychology Department posted instructions in the bathroom persuading all of us to "Think about five things for which you're grateful every day for a week!" my response was frankly doubtful. I did the math. Five things a day for seven days is a lot of brainpower to expend without so much as the promise of an apple pie.
I wandered into the office of Heidi Zetzer, the director of our school's Psychological Services Clinic. "What's with the gratitude thing?" I asked. You don't ask an academic question－even a simple one unless you're prepared for a long answer. Heidi came alive, and I sat down. That's when I first heard the term "positive psychology". The gratitude thing, as I had called it, was but one small and simple element of the practice. "Kind of like training the brain to focus on joy," my friend Heidi explained. "It's only a week," she urged. "Try it." I did. And guess what? It worked. Every day for a week, I found five distinct things for which I was thankful. They had to be different every day. I couldn't get away with just being grateful for my wonderful husband. But I could, suggested Collie Conoley, another positive psychologist, express my gratitude for specific aspects of a certain person each day. He's a great cook. He always puts our family first.
Life will never be perfect. I still see new stories that annoy me. The traffic in my city is maddening. I wish I could speed up my recovery. But with just one simple exercise, I'm rediscovering the peace of that old saying: accepting the things I can't change, working without complaint to change what I can, and being wise enough to know the difference.
And all it took was a little gratitude.
（1）What's the author's attitude toward the student with desserts?
A. Cautious.
B. Respectful.
C. Indifferent.
D. Supportive.（2）Why was the author doubtful about the instructions?
A. Because she thought it wasn't worth the effort.
B. Because she didn't like expressing thanks often.
C. Because she needed to ask her friend to do it first.
D. Because she could do five things every day easily.
（3）What does Collie Conoley suggest the author should do?
A. Be grateful to her wonderful husband.
B. Be thankful for things but not people.
C. Be a great cook and put her family first.
D. Be specific about what she's thankful for.
（4）What's the best title for the text?
A. Don't Be Bothered by Small Things
B. We Can Change Everything If We Want
C. Practicing Gratitude Changed My Life
D. Being Grateful to One Good Person
【答案】（1）A
（2）A
（3）D
（4）C
【解析】【分析】本文是一篇夹叙夹议文，在一个星期的时间里，作者坚持每天都能发现五件她特别感激的事情，而且每天都有所不同。

生活永远不会完美。

但通过这么一个简单的练习，作者重新发现了那句老话的平和：接受我不能改变的事情，毫无怨言地去改变我能改变的，并且足够明智地知道两者的区别。

这只需要一点感激之情。

（1）考查推理判断。

根据第一段中的“If an eager graduate student showed up in my office bearing desserts and asked me to pick one, I'd cast a careful glance and ask ‘Why?’ before grabbing the apple pie.”如果一个心急的研究生拿着甜点出现在我的办公室，让我挑选一种，在抓苹果派之前，我会仔细地看一眼，然后问“为什么?”可知，作者在抓苹果派之前，会仔细地看一眼，然后问“为什么?”。

4．阅读理解
You're probably used to the regular upgrades in our cell-phone networks. There was 2G, which came along in 199l, replaced with 3G in 2001, followed by 4G in 2009. Now we're hearing about the coming of 5G.
But 5G is a much bigger leap than before. 5G, of course, is much faster than 4G in the real world and a 5G phone in a 5G city will enjoy Internet speeds between 9 and 20 times as fast. The
arrival of 5G also means enormous leaps forward in capacity－so much that every cell-phone plan will offer cheap, truly unlimited Internet access. "The consequences of that are huge," says Sherif Hanna, Qualcomm's director of 5G marketing. For example, apps will no longer degrade (降低) your video quality or postpone downloading when you're out of Wi-Fi range. In fact, you'll probably prefer to do your downloads when you're on cellular (使用流量) because 5G will be much faster than whatever service you've got at home or work.
"However, not everyone is excited by the 5G development. The new standard gets its speed partly by using existing transmission(传输) frequencies more efficiently and partly by using the millimeter wave range. That's a big, juicy line of radio frequencies that are currently underused because millimeter wave is really hard to use," Hanna says.
These frequencies are much higher than anything we've used for the cellular, which means they can offer unbelievable speed－but at the cost of range. Millimeter wave cellular towers have to be about 500 feet apart. Cell carriers not only will have to upgrade all their cell transceivers (called small cells) but will install(安装) a lot more of them as well.
That's why the millimeter wave flavor of 5G, the superfast coverage, will be available only in densely populated cities such as New York and San Francisco. In suburban and rural areas, 5G will bring a speedup of "only" nine times faster.
（1）What advantages does 5G have over previous networks?
A. 5G is much faster and more convenient.
B. 5G allows users to download more videos.
C. 5G can provide better service and news at home.
D. 5G cell-phone plans are expensive but more accessible.
（2）Hanna's words in paragraph 3 reflect .
A. popularity of the coming of 5G
B. easy access to the 5G development
C. concern about the 5G development
D. excitement about the 5G development
（3）What can we learn about 5G according to the text?
A. It requires more cellular towers.
B. It won't be available in rural areas.
C. It won't show speed improvements in suburbs.
D. It makes some populated cities even more crowded.
（4）Where is the text most likely from?
A. A tour brochure.
B. A science newspaper.
C. A medical magazine.
D. An experimental textbook.
【答案】（1）A
（2）C
（3）A
（4）B
【解析】【分析】本文是一篇说明文，介绍了5G网络的一些基本情况。

（1）考查细节理解。

根据第二段中的“But 5G is a much bigger leap than before. 5G, of course, is much faster than 4G in the real world and a 5G phone in a 5G city will enjoy Internet speeds between 9 and 20 times as fast.”但5G的发展比以前大得多。

当然，在现实世界中，5G比
4G快得多，5G城市中的5G手机将享受9到20倍的网速。

可知，5G手机的网速将大幅度提高。

由此可知，与以前的网络相比，5G更快、更方便。

故选A。

（2）考查推理判断。

根据第三段中的“‘However, not everyone is excited by the 5G development…That's a big, juicy line of radio frequencies that are currently underused because millimeter wave is really hard to use,’ Hanna says.”汉纳说:“然而，并不是每个人都对5G的发展感到兴奋……这是一个巨大的、有趣的无线电频率线，目前还没有得到充分利用，因为毫米波真的很难使用。

”可知，汉纳认为并不是每个人都对5G的发展感到兴奋，这种无线电频率线，目前还没有得到充分利用。

由此推知，汉纳在第3段中的话反映了对5G发展的担忧。

故选C。

（3）考查细节理解。

根据第四段中的“Cell carriers not only will have to upgrade all their cell transceivers (called small cells) but will install(安装) a lot more of them as well.”手机运营商不仅要升级他们所有的手机收发器(称为小型小区，还要安装更多的收发器）可知，5G不仅需要手机运营商升级他们所有的手机收发器，还要安装更多的收发器。

可推知，5G需要更多的手机基站。

故选A。

（4）考查推理判断。

根据第一段中的“There was 2G, which came along in 199l, replaced with 3G in 2001, followed by 4G in 2009. Now we're hearing about the coming of 5G.”1991年出现的2G, 2001年被3G取代，2009年又出现了4G。

现在我们听到了5G的到来。

可知，本文主要介绍了5G网络的一些基本情况。

5G网络的发展属于科技进步，结合选项可知，本文应该来自科学报纸。

故选B。

5．阅读理解
For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents' point of view, the only cause of their fight is their adolescents' complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I'll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrel on unimportant things. Examples include the color of the teen's hair, the cleanness of the bedroom, the preferred style of clothing, the child's failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn't matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and
teens continue to assume that they know more than the other, they'll continue to fight these battles forever and never make any real progress.
（1）Why does the author compare the parent teen war to a border conflict?
A. Both can continue for generations.
B. Both are about where to draw the line.
C. Neither has any clear winner.
D. Neither can be put to an end.
（2）What does the underlined part in Paragraph 2 mean?
A.The teens blame their parents for starting the conflict.
B.The teens agree with their parents on the cause of the conflict.
C.The teens accuse their parents of misleading them.
D.The teens tend to have a full understanding of their parents.
（3）Parents and teens want to be right because they want to__________.
A.give orders to the other
B.know more than the other
C.gain respect from the other
D.get the other to behave properly
（4）What will the author most probably discuss in the paragraph that follows?
A.Causes for the parent-teen conflicts
B.Examples of the parent-teen war
C.Solutions to the parent-teen problems
D.Future of the parent-teen relationship
【答案】（1）B
（2）A
（3）C
（4）C
【解析】【分析】本文是一篇说明文，对于父母来说，抚养一个十几岁的孩子就像是打一场持久战，但是是一场没有赢家的持久战。

（1）考查细节理解。

根据第一段中的“Like a border conflict between neighboring countries ,the parent-teen war is about boundaries: Where is the line between what I control and what you do?”可知和邻国之间的边界纷争一样，两代人之间的战争是关于界限的：我所能控制的和你所做的之间的界限。

选B。

（2）考查句义猜测。

根据第二段中的“From the parents' point of view, the only cause of their fight is their ado lescents' complete unreasonableness.”可知，从父母的观点来看，他们之间斗争的唯一原因就是他们的青春期的孩子的完全不讲道理。

划线句子意为:青少年也正好是同样的方式看待的，只是正好相反的，也就是在孩子们看来，斗争的原因完全是他们的父母蛮不讲理。

选A。

（3）考查细节理解。

根据最后一段中的“Third , needing to be right ,It doesn't matter what the topic is –politics. The laws of physics ,or the proper way to break an egg –the point of these arguments is to prove that you are right and the other person is wrong , for both wish to be considered an authority—someone who actually knows something —and therefore to command respect”可知，他们争论的话题是什么不重要，重要的是他们要证明自己是对
的，而对方是不对的，从而赢得尊重。

选C。

（4）考查推理判断。

根据由最后一段中的“In this article, I'll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap.”可知，在这篇文章中，作者将描述三种通常会引起青少年和父母之间斗争的情形，然后提出几种解决的方法。

最后一段介绍了三种情形，所以接下来讨论的该是解决的方法了。

选C。

6．阅读理解
People who sleep fewer than six hours a night are more likely to die early, researchers in University of Warwick have found in a recent study. They discovered that people who slept for less than six hours each night were 12% more likely to die before the age of 65 than those who slept the recommended six to eight hours a night.
The researchers pointed out that previous studies had shown that the lack of sleep was associated with problems like heart disease and high blood pressure. However, the researchers also found that sleeping too much was linked to an early death. Those who slept for more than nine hours a night were 30% more likely to die early, as an article in the latest Sleep suggested. That directly contradicts another passage in the same journal last month suggesting that people who slept for ten hours or longer a night were more likely to live to 100. This was thought to be because people who lived into extreme old age were healthier and therefore slept better.
However, the authors of the latest research contradicted this and suggested that long sleep was a sign of underlying illnesses such as depression and low levels of physical activity. Professor Francesco Cappuccio at the University of Warwick said: "While short sleep may represent a cause of ill-health, long sleep is believed to represent more an indicator of ill-health."
He also mentioned: "Modern society has seen a gradual reduction in the average amount of sleep people take, and this pattern is more common among full-time workers, suggesting that it may be due to social pressures for longer working hours. On the other hand, the worsening of our health is often accompanied by an extension of our sleeping time."
"Consistently sleeping six to eight hours per night may be good for health. However, whether to achieve the goal depends on various factors such as the environment as well as measures of public health aimed at favourable changes of the working environments," Professor Francesco Cappuccio added.
（1）What did researchers in University of Warwick find?
A. People who sleep fewer than 6 hours each night die before 65.
B. Sleeping for more than 9 hours a night does good to one's health.
C. Six to eight hours' sleep can be appropriate for people.
D. People at an old age are healthier because they sleep longer.
（2）What is Professor Francesco Cappuccio most likely to agree with?
A. Long sleep is what causes our health problems.
B. Modern people sleep less because they work longer.
C. Our health becomes worse because we sleep less.
D. How long we sleep depends on our education.
（3）What did the researcher think may help people have proper sleep?
A. Social pressure.
B. Longer working hours.
C. Extension of sleeping time.
D. Changes of working environments.
（4）What can be the best title for this passage?
A. How Long Should We Sleep
B. Longer Sleep Makes Better Health
C. Time to Sleep Early
D. The Importance of Sleep
【答案】（1）C
（2）B
（3）D
（4）A
【解析】【分析】本文是一篇说明文，研究发现，每晚睡眠不足6小时的人死亡风险更大。

每晚睡6至8小时最合适。

（1）考查推理判断。

根据第一段中的"They discovered that people who slept for less than six hours each night were 12% more likely to die before the age of 65 than those who slept the recommended six to eight hours a night."可知，研究者们发现，每晚睡眠不足6小时的人在65岁之前死亡的可能性比那些每晚睡足6至8小时的人高出12%。

由此可知，每晚睡足6至8小时是比较合适的。

故选C。

（2）考查推理判断。

根据倒数第二段中的"Modern society has seen a gradual reduction in the average amount of sleep people take, and this pattern is more common among full-time workers, suggesting that it may be due to social pressures for longer working hours"可知，Professor Francesco Cappuccio认为：现代社会中，人们的平均睡眠时间逐渐减少，这种模式在全职工作者中更为常见，这可能是由于长时间工作的社会压力造成的。

故选B。

（3）考查细节理解。

根据最后一段中的"Consistently sleeping six to eight hours per night may be good for health. However, whether to achieve the goal depends on various factors such as the environment as well as measures of public health aimed at favourable changes of the working environments"可知，能否实现每晚睡足6至8小时这个目标取决于环境的改变以及针对工作环境变化的公共卫生措施等多种因素。

由此可知，工作环境的改变是帮助人们获得适当睡眠的方法之一。

故选D。

（4）考查主旨大意。

第一段点明研究结果：每晚睡眠不足6小时的人在65岁之前死亡的可能性比那些每晚睡足6至8小时的人高出12%。

下文针对这一研究结果，分析了导致这种结果的原因，解决方法等。

8．阅读理解
When you live in total messiness—cookies in your pants draws, and some old New Yorkers or apple seeds in your bed—it's hard to know where to look for when you lose your keys. The other day, after two weeks of searching, I found my keys in the refrigerator. I can't say I was surprised. But I was surprised when I was diagnosed with ADHD(多动症), when I was a junior at Yale.
According to a new study, 11% of school-age children have received an ADHD diagnosis, a 16% increase since 2007. And rising diagnoses mean rising treatments—drugs like Adderall are more accessible than ever. However, the consequences of misuse and abuse of these drugs are dangerous.
Yet also harmful are the consequences of ADHD undiagnosed, an all-too-common story for women like me, who have symptoms, like disorganization and forgetfulness, which look different from those typically expressed in males.
Dr. Ellen, author of Understanding Girls with ADHD, has found around 4 million females with ADHD are not diagnosed. "The main reason is that the diagnostic criteria were developed based on those hyperactive（过度活跃）young boys taken to clinics, making it difficult for girls to be diagnosed unless they behave like hyperactive boys." Ellen says.
Besides, the idea that young women actually have ADHD often causes skepticism. As a top student, I didn't believe my diagnosis at first. My friends were also confused, and rather certain my doctor was misguided.
"Often, if girls are smart or in supportive homes, symptoms are masked," Dr.Ellen says. "Girls will hide their inability to meet social expectations. They see their trouble organizing, and concentrating as character flaws(缺陷)."
These years, I am both embarrassed and exhausted by my struggles to keep track of objects, but drug has helped it and made it more bearable.
