Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people’s increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy.
When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陈代谢) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energy-demanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you’re being chased by a tiger, you don’t need to waste energy making immune cells to fight off tomorrow’s cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.
As a result, our immune system evolved to run in maximum amounts when we’re happy, but to slow down dramatically when we’re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, becoming more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.
【1】According to Robert Trivers, when our body needs extra energy, ______.
A. muscles will respond to it by relaxing a little bit
B. organs will speed up metabolic processes to answer it
C. immune system will temporarily shut down to fulfill it
D. brain will satisfy it by sharing optional metabolic output
【2】In paragraph 3 “this relationship” most probably refers to the one between ______.
A. experiences and related knowledge B. happiness and biological evolution

【3】What can be concluded from Robert Trivers’ study?
A. Younger people adopt strategies of handling tense situations from everyday life.
B. Our ancestors evolved their immune systems in fighting against fierce animals.
C. Realizing that their days are numbered, older people prefer being positive.
D. Being negative drains energy from our body, lowering resistance to disease.
【4】Which of the following is the best title of the passage?
A. Brain, muscles and immune system B. Age, health and happiness

(2019·北京高考)What students do at college seems to matter much more than ________ they go.
I was caught in a traffic jam for over an hour, otherwise, I ________ (keep) you waiting for such a long time.
Do you ever feel like you are studying a mad rush of one subject after another? When things happen at such a 1 pace, it is easy to lose sight of what you are learning. It is important to 2 every now and then to think about what you’ve been learning.
Self reflection means stopping the mad rush and 3 yourself so your brain can evaluate what it has already 4 . Some people prefer to do their self reflections 5 ,while others keep a journal. Either method can work, depending on what your own personal 6 is.
School textbooks are often divided into units. This can make it 7 for someone to begin the process of self reflection. Watch for the times when you complete a unit of study. Sometimes you are reminded that the unit is 8 because there is some kind of test or quiz. Use these natural 9 as opportunities to stop and reflect.
You should find a 10 place- anywhere without noise is OK. This can even be sitting at your desk at school when you finish something 11 and the other students are still working. If you are going to take notes, take out your journal. Write down some notes on things that you 12 learned in this unit. Let your mind think about the notes you have written and make some 13 .
Sometimes just pausing to think deeply allows your brain to make connections 14 new information can quickly appear when you 15 it again. Next, think about things you still wonder about. 16 maybe you learned about a certain body system, but you don’t 17 how it works with the other body system. Maybe you learned a new way to solve a math problem, but you’re not sure when to use it. Writing down your 18 will help you remember to continue seeking answers the next time you 19 the same topic.
Self reflection is an essential skill for a 20 student. If you have never taken the time to reflect, try it now.

“Sorry seems to be the hardest word”—that is one of Elton Johns most popular songs. But not every public figure seems to find it so tough to say that powerful five-letter word.
In recent days public figures, from politicians to stars, have all publicly expressed remorse. But with so much remorse, how can we tell a forced apology from a heartfelt expression of remorse?
Specifically, saying sorry should be a realization that something you have said or done has hurt someone and you want to make amends. “People wants the response to be personal to them. They want to feel that they’re being listened to and taken seriously,” says Martin Stone.
Firstly, it is important to show that you understand. It is vital that any group or a person making an apology understands the focus—is it sorry for the way it’s acted or is it sorry that the complainant feels the way they do? Watch out for the speed of response. The quicker the apology comes, the better it indicates that the person making it has felt an immediate sense of guilt.
If sincere, the person making the apology will be looking for clues (线索) to see if he or she is being understood, such as eye contact and facial expressions. Performed apologies always have a sense of being “acted out”, and are often accompanied by too many unnatural gestures.
For a sincere apology, it is also important to avoid promises that can’t be kept. Don’t say that you’ll make sure that this will not happen again if you re not confident that it wont. It could come back to bite you. And do remember that the use of “but” can hugely change the tone (语气) of an apology. As Stone points out, “I’m sorry but...” sounds like you are making excuses and aren’t actually taking any form of responsibility.
【1】What does the underlined word “remorse” probably mean?
A. Feelings. B. Appereciation. C. Regret. D. Sympathy.
【2】Which of the following indicates it’s a performed apology?
A. Swearing it will not happen again. B. Avoiding eye contact with the listener.
C. Showing you understand his /her feelings. D. Paying attention to the listener’s reaction.
【3】What is stressed in the last paragraph?
A. The attitude. B. The tone of voice.
C. The body language. D. The choice of language.
【4】What is the purpose of the text?
A. To explain what a good apology is.
B. To discuss how to give a formal apology.
C. To show why we should apologize in life.
D. To teach us how to tell if an apology is sincere.

WARNING: Holding a cellphone against your ear or storing it in your pocket may be dangerous to your health.
This paraphrases (解释) a warning that cellphone manufacturers include in the small print that is often taken for granted when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters. Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.
If health issues arise from cellphone use, the results are serious. Voice calls—Americans chat on cellphones 2.26 trillion minutes annually—bring in $109 billion for the wireless carriers.
Devra Davis, who has worked for the University of Pittsburgh, has published a book about cellphone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cellphones arrived. But the average covers an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable (易受伤害的) to radiation than adults, Ms. Davis and other scientists point out. Radiation that enters the brain of an adult only five centimeters will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cellphone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should send text message rather than call, she said, and pregnant women should keep phones away from the abdomen (腹部).
| Topic | Keep a certain (71) from cellphones. |
| Several (72)_____ | A (n)(73) in brain cancer in the 20-to-29 age group. Low-energy radiation could (74) cells possibly leading to cancer. Children are more (75) to radiation. Rats to radiofrequency radiation had damaged DNA in their brains. A (n)(76) in brain cancer in the 20-to-29 age group. Low-energy radiation could cells possibly leading to cancer. Children are more (77) to radiation. A (n)(78) in brain cancer in the 20-to-29 age group. Low-energy radiation could (79) cells possibly leading to cancer. Children are more (80) to radiation. |

Electric cars are dirty. In fact, not only are they dirty, they might even be dirtier thantheir gasoline-powered cousins.
People in California love to talk about “zero-emissions vehicles”, but people inCalifornia seem to be clueless about where electricity comes from. Power plants mostly use fireto make it. Aside from the new folks who have their roofs covered with solar cells, we get ourelectricity from generators (发电机). Generators are fueled by something—usually coal, oil,but also by heat generated in nuclear power plants. There are a few wind farms andgeothermal (地热)plants as well, but by far we get electricity mainly by burning something.
In other words, those “zero-emissions” cars are likely coal-burning cars. It’s justbecause the coal is burned somewhere else, it looks clean. It is not. It’s as if the CaliforniaGreens are covering their eyes—“ If I can’t see it, it’s not happening.” Gasoline is anincredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But whenyou take that gas (or another fuel) and first use it to make electricity, you waste a nice partof that energy, mostly in the form of wasted heat—at the generator, through the transmissionlines, etc.
A gallon of gas may propel your car 25 miles. But the electricity you get from that gallonof gas won’t get you as far — so electric cars burn more fuel than gasoline-poweredones. If our electricity came mostly from nukes or geothermal, or hydro or wind or solar, thenan electric car truly would be clean. But for political, technical, and economic reasons, wedon’t use much of those energy sources.
In addition, electric cars’ batteries which are poisonous for a long time will eventuallyend up in a landfill. And finally, when cars are the polluters, the pollution is spread acrossall the roads. When it’s a power plant, though, all the junk is in one place. Nature is verygood at cleaning up when things are too concentrated, but it takes a lot longer when all thegarbage is in one spot.
【1】What is the main idea of the text?
A. Electric cars are far from being clean.
B. Electric cars are better than gasoline-powered ones.
C. People cast doubts on electric cars’ batteries.
D. Gasoline is an efficient way to power a vehicle.
【2】The electricity we get from a gallon of gas may make our car run.
A. no less than 25 miles B. as far as 50 miles
C. less than 25 miles D. as far as 25 miles
【3】According to the text, electric cars.
A. are more environmentally friendly
B. burn more fuel than gas-powered ones
C. are very good at cleaning up when things are not too concentrated
D. are poisonous for a long time and will eventually end up in a landfill
【4】It can be inferred from the text that.
A. being green is good and should be encouraged in communication
B. electric cars are the dominant vehicles compared with their gas-poweredcousins
C. zero-emissions vehicles should be chosen to protect our environment
D. electric cars are not clean because we get electricity mainly by burning something

Directions: Read the passage carefully. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Many people know that trash is a big problem on planet Earth. What many people don’t know is that trash has become a problem in outer space too. 【1】
Statistically, there are more than 22,000 pieces of junk in space around the earth. And these are just the items that we can see from the surface of the earth by telescopes or radars. 【2】
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to people, particularly astronauts. If the tiniest piece of junk crashed into a spacecraft, it could damage the vehicle. That’s because the faster an object moves, the greater the impact if the object collides with something else.
To help minimize additional space junk, countries around the world have agreed to limit the time their space tools stay in orbit to 25 years. Each tool must be built to fall safely into the earth’s atmosphere, or the mass of gases that surround the earth, after that. 【3】
Many scientists are also proposing different ways to clean up space junk. The Germans have been planning a space mission with robots that would collect pieces of space trash and bring them back to Earth so that they can be safely destroyed.
"In our opinion the problem is very challenging, and it's quite urgent as well," said Marco Castronuovo, an Italian Space Agency researcher who is working to solve the problem. 【4】 Many of these objects are tools that help people use their cell phones or computers.
"The time to act is now; as we go farther in time we will need to remove more and more fragments," he says.
A. One reason that it’s urgent is that countries are sending more and more objects into space.
B. There are also millions of smaller pieces of junk that we can’t see.
C. Blowing up older satellites with a missile may create thousands of smaller pieces!
D. In the upper parts of the atmosphere, it will burn up.
E. When two objects in space collide, the two objects break into many smaller pieces.
F. Years of space exploration have left tons of “space junk” in orbit around the planet.
If you are not reading this on a screen then you hold in your hands one of humanity’s world-changing inventions. Yet that power has not been matched by fame: paper delights in self-modesty, pointing you to the words on its surface and so acting only as a stage for ideas and arguments that have changed history.
Without that stage, the written and printed word would have attracted only a small audience.All the alternatives to paper commonly used throughout our pre-digital history have been too rare, too heavy, too expensive or too inconvenient to deliver words to a wide number of people,let alone a mass readership
Paper has enabled writers to reach unprecedented(前所未有) numbers throughout history.Among them were the Buddhist missionary translators from South and Central Asia who brought their religion to China almost two thousand years ago. The paper age has its outstanding personalities: Lev Nikolayevich Tolstoy and Johann Wolfgang von Goethe, whose collected works when combined fill more than 200 volumes.
For many of us, it has only been the rise of digital media that has finally opened our eyes to papers striking existence everywhere. Of course, paper has found thousands of roles for itself,writing aside. Your bedside lamp glows through a paper cover and the cups in the office coffee machine are made from paper. It can be as common and practical as a bus ticket or it can be treasured and expensive as the carrier of the worlds best-loved painting.
It is clear that many predictions of paper's extinction have been premature-and greatly overstated. Much of the 400 million tons of paper produced annually is absolutely necessary to our way of life. The bigger question, of course, concerns the one role paper has had that has been transformative for the world. namely as the carrier of written or printed text. Already,it is leaving much of the difficult work of words to digital media, and many of its centuries-old roles have already been largely transferred to the screen. There is also a sense in which paper has itself become a subject, rather than simply a medium. This began to become clear in art several decades ago. as paper became not simply the backdrop (背景) for art but, in a few cases, the stuff of the art itself.
This doesn’t mean that papers uses as a vehicle for words will end, but it does signal a slowing down. More than that, it signals that paper's greatest virtues are no longer good enough.Those virtues enabled unprecedented periods of cultural expansiveness. just as they encouraged knowledge, beliefs and ideas to move further down the socio-cconomic ladder. Yet such transformative qualities are shared by paper's digital opponent(对手), and paper can no longer compete on speed of delivery, scale of information immediately available, or ease of access.
Paper's historic dynamism(活力)has received its first great challenge and, in many aspects,it appears to be losing Nostalgia(怀旧)simply dismisses paper to a museum piece. But there are reasons to think that the dynamism that paper has exhibited over some 20 centuries will not be transferred totally to digital media. There are a few practical reasons. Electric power is always needed for digital media, of course. More importantly, anything online can, potentially, be hacked into. Your own reading choices can be viewed from the other side of the world. Even what you write can be viewed and changed or deleted. But it is the ownership of knowledge that matters most. As Amazon recently reminded a kindle reader who had lost the text of a book he was reading. you do not "own" your books on Kindle, as you own a physical book. You simply have the right to access them.
The digital revolution certainly provides unprecedented access to knowledge. But it is access only. Text that you can hold, shelve and own, due to paper, will always have a magic all its own.
【1】Why does paper not have well-deserved fame?
A. Much information is available on a screen.
B. It takes great delight in being modest.
C. Only a small crowd enjoys the benefits of it.
D. It always guides readers to focus more on itself.
【2】The underlined part in Paragraph 4 implies that the digital media .
A. ignores the existence of paper
B. promotes the wide use of paper
C. replaces the functions of paper
D. helps us realize the roles of paper
【3】One reason why paper won' t come to an end is that .
A. it is being mass-produced
B. it is more than a medium
C. it has a centuries-old role
D. it is a well-known invention
【4】What’s the purpose of mentioning the best virtues of paper in Paragraph 6?
A. To show its fast development.
B. To prove its unchanged strength.
C. To indicate its loss of competitiveness.
D. To bring back its past brilliance.
【5】What is the biggest problem the digital media face?
A. It depends on electric power.
B. Personal privacy is easy to leak.
C. Users only have the right to use.
D. The joy of reading is hard to feel.
【6】What is the best title for the passage?
A. The History of Paper
B. The Power of Paper
C. The Development of Paper
D. The Application of Paper
The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.
That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.
“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.
For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.
In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.
25. What does the underlined word “that” in paragraph 2 refer to?
A. Increased length of green lights. B. Shortened traffic signal cycle.
C. Flexible timing of traffic signals. D. Smooth traffic flow on the road.
26. What does Kevin Balke say about adaptive signals?
A. They work better on broad roads.
B. They should be used in other cities.
C. They have greatly reduced traffic on the road.
D. They are less helpful in cities seriously jammed.
27. What can we learn from Bellevue’s success?
A. It is rewarding to try new things. B. The old methods still work today.
C. I pays to put theory into practice. D. The simplest way is the best way.
