考点 1 逻辑推理
1．A few years ago, Charles Barkley got into a lot of trouble for making the observation that sports figures didn’t need to be role models. Thousands of fans and professional journalists were
cross at this attack on the fundamental principle that the person who jumps highest must aim highest and the person who handles the running back must also be able to deal with life’s
problems with grace as well.
The problem is not that we look to these people for perfection when they take off their
uniforms. It’s that we expect anyone to be our representatives for perfection. That’s stupid and it makes the rest ofus down here lazy.
I get the importance of having heroes, the people who inspire us to cultivate the best
potential within us and nurture our better angels. I personally have many heroes, from my mother, Lucy, to my favorite law professor, Howard. But these are personal contacts, people who
have-actually touched my hand and my heart, and who occupy a pedestal (基座) built of my own experiences and aspirations. To look at an athlete or an actress with high salary and demand that he or she match our dreams is not only a waste of time, but it’s dangerous. The danger comes in how this type of hero worship dehumanizes both the object of affection and the person who
blindly adores. That was Barkley’s point, not that we should give public figures a pass for being faulty but that we shouldn’t abandon our own moral compasses and look to them for true north.
Recently on a television program I participated in, the discussion turned to Kathleen Kane. Someone suggested that the fact that the first female attorney general (首席检察官) in
Pennsylvania was really messing things up could have unfortunate consequences for women

seeking elected office. I offered the opinion that Kane was unquestionably criticized and that it
was not hatred towards woman but incompetence at the root of the attacks. After the show aired, I had people emailing to tell me that I was either a traitor (叛徒) for publicly attacking a fellow
female when we need to stand together behind this “role model”, or a fool for not going a step
further to say that this incompetent lawyer had made it harder for all women to move to the next level.
How depressing! Why should the inferior performance of one woman lead to such diverse but passionate views in people The answer is obvious: Kane has stopped being an attorney
general but has instead become The First Female Attorney General. She can’t just make a mistake and pay the normal consequences.
If we stopped trying to live our lives through the accomplishments of public figures, many of
whom look and sound like us, we’d learn how to recognize the heroic character of those we might actually know, and the heroic potential within ourselves. Or, perhaps, the honesty to accept our
ordinary humanity.From the passage we can infer that Kathleen Kane was .
A ．unfairly criticized due to being female B ．the first female attorney general in the US
C．less qualified than the public had expected D．a role model for women seeking elected office
2 ．My fingers trembled as I signed the pre-medical application form. The watercolor
brushes on my desk stared back at me like abandoned friends. I’m Lora, an 18-year-old who
secretly drew brain diagrams on napkins while classmates drew cartoons. “Art feeds the soul but starves the body,” Mom always said. Her words haunted me as my biology textbooks slowly
buried my drawing pads.
Then came the school career fair that changed everything. Dr. Eleanor Whitman from
Harvard asked us to list our “hidden skills”. My hand shook as I wrote “observing
details”—something I’d learned from painting flower petals. “That’s medical research’s most
needed skill!” she exclaimed, sharing how a student turned microbiology notes into textbook
illustrations. My lab partner whispered, “Remember our photosynthesis (光合作用) comic ” For the first time, my two worlds didn’t feel so separate.
The real surprise came during hospital volunteering. Watching surgeries, I noticed
something—the steady hands of doctors reminded me of my brushwork. When a boy struggled to describe his pain, I drew a fire-breathing dragon on his cast. “You made medicine speak,” the
试卷第 2 页，共 11 页
nurse said. Slowly, my drawing pads filled with cells that looked like colored-glass art and X-rays arranged like abstract paintings.
Mr. Dawson, our career counselor, helped connect these dots. On his whiteboard, my
medical knowledge and art skills overlapped in a bright yellow circle labeled “Medical
Illustration”. He showed me job listings I never knew existed—graphic designers for science apps, 3D modelers for anatomy (解剖) classes. “Your ‘impractical’ skill makes you stand out,” he said, pointing to my dragon drawing now used in pain management workshops.
Today, my microscope and paintbrushes share the same desk. The same hands that once hesitated between them now create 3D models of viruses for vaccine education. Sometimes I teach young patients to draw their feelings instead of describing them. My story isn’t about heart and reality

A ．a plus. B ．a leisure. C ．a distraction. D ．a burden.
3．When the need for information technology service arises, it can be a stressful moment — the user is locked out of their computer, or a program isn’t working properly. But if you ask
anyone in the MIT departments of Chemistry and Physics, or the News Office — the Institute
divisions that are fortunate enough to have Greg Walton as their IT service provider, they’ll
acknowledge that not only is Walton the best, but whatever the issue is, he will see it through until all involved are satisfied with the outcome. Walton usually arrives on the scene with endless
positive energy that transforms a technical annoyance into an enjoyable interaction, regardless of how many other IT fires he has already put out that day.
The qualities that make him a star employee extend far beyond the campus. After spending his early years in foster care, Walton lived with his great-grandmother, but mostly, he was left to support himself. While many children might, understandably, lie flat under such unsupervised
circumstances, Walton excelled academically and athletically at high school. He became the first person in his family to graduate from high school, and enrolled in college.
Walton seized the chance to enroll in Year Up, a program aiming to close the “opportunity divide” by providing young adults with the skills, experience, and support that will empower them to reach their potential through professional careers and higher education. Walton remains an
active ambassador for the organization.
试卷第 3 页，共 11 页
In June of 2007,armed with shining recommendations, Walton was hired as a temp (临时工) at MIT. He eventually worked his way up to where he is today — an invaluable asset (不可或缺的人) to three departments.“I do feel lucky to work at MIT,” he says.“I’ve had the ability to
tour the country sharing my story in hopes that some people may be inspired and employers may see young adults with tough backgrounds differently.”
In addition to Year Up, he is involved with a number of organizations committed to helping young adults overcome their troubled pasts. This desire to have a positive impact on people’s lives extends seamlessly into his work at MIT. “Giving back is very important to me,” Walton says. “So many people have invested their time and energy into helping me, so I feel it would be an injustice not to do so.”
What can we conclude from Walton’s story
A ．One good turn deserves another.
B ．Opportunities favor the prepared mind.
C ．Education is a powerful weapon to change the world.
D ．One’s future is defined by his efforts, not by his origin.
考点 2 观点态度
4．Not too long ago, on a cold winter night, there was a teenager who wanted more screen time and a parent who said no. The teenager was advocating for her right to scroll (翻屏) for an
extra 30 minutes. The parent argued that none of her friends’ parents let them have screens after 9 o’clock. “I thought, in this family, we don’t compare ourselves with other people, Dad ” the
teenager replied. The parent — who was me, by the way —just got served. Since they were
young, I have told my kids not to compare themselves with other people. I have argued countless times that comparisons are the “thief of joy”.
Although my daughter didn’t win, she did help expose one of the worst pieces of advice I have ever given. In my defence, I did what we’ve all done before, which is to repeat received
wisdom without exploring the nuances. But now is the time to set the record straight, which starts with questioning the idea that all social comparison is unhealthy.
Social comparisons do, of course, often get us into emotional trouble. But they can be
harnessed (利用) for our betterment if we understand how they work. The social comparisons we
试卷第 4 页，共 11 页
make — ones that lead us to feel good or bad about ourselves — are vital to our ability to thrive (成长). Science provides a guide we can use to harness the way we perform these comparisons to reduce their negative emotional impacts.
Comparing yourself with someone who is outperforming you could result in feelings of envy if you focus on the things they have and you don’t, or it can be energizing and inspiring if
you use these comparisons as a source of motivation, for example, “If they can achieve that, so
can I.” Comparing yourself with someone who is doing worse than you could result in fear and
worry if you think about how you could fall into similar circumstances, or it can draw out feelings of gratitude and appreciation if you use that comparison to broaden your views — for example,
“Wow, things could be much worse; I’m doing great.”
What I wish I taught my daughter earlier are these nuances. How we feel about ourselves rests not just on whom we compare ourselves with but also on how we think about that
comparison. That’s something we all have control over.
How did the author feel about his daughter’s argument
A ．Excited. B ．Inspired. C ．Energized. D ．Relieved.
5 ．The notion that we live in someone else’s video game is irresistible to many. Searching the term “simulation hypothesis” (模拟假说) returns numerous results that debate whether the
universe is a computer simulation — a concept that some scientists actually take seriously.
Unfortunately, this is not a scientific question. We will probably never know whether it’s true. We can, instead, use this idea to advance scientific knowledge.
The 18th-century philosopher Kant argued that the universe ultimately consists of
things-in-themselves that are unknowable. While he held the notion that objective reality exists, he said our mind plays a necessary role in structuring and shaping our perceptions. Modern sciences
have revealed that our perceptual experience of the world is the result of many stages of
processing by sensory systems and cognitive (认知的) functions in the brain. No one knows
exactly what happens within this black box. If empirical (实证的) experience fails to reveal reality, reasoning won’t reveal reality either since it relies on concepts and words that are contingent on
our social, cultural and psychological histories. Again, a black box.
So, if we accept that the universe is unknowable, we also accept we will never know if we live in a computer simulation. And then, we can shift our inquiry from “Is the universe a computer
试卷第 5 页，共 11 页
simulation ” to “Can we model the universe as a computer simulation ” Modelling reality is
what we do. To facilitate our comprehension of the world, we build models based on conceptual metaphors (隐喻) that are familiar to us. In Newton’s era, we imagined the universe as a clock. In Einstein’s, we uncovered the standard model of particle (粒子) physics.
Now that we are in the information age, we have new concepts such as the computer,
information processing, virtual reality, and simulation. Unsurprisingly, these new concepts inspire us to build new models of the universe. Models are not the reality, however. There is no point in
arguing if the universe is a clock, a set of particles or an output of computation. All these models are tools to deal with the unknown and to make discoveries. And the more tools we have, the more effective and insightful we can become.
It can be imagined that comparable to the process of building previous scientific models, developing the “computer simulation” metaphor-based model will also be a hugely rewarding exercise.
As for Kant’s argument, the author is .
A ．appreciative
B ．doubtful
C ．unconcerned
D ．disapproving
6 ．Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly
self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be
noted, isn’t leading the way panies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars (and
rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce
试卷第 6 页，共 11 页
traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy — or even worsen — the traffic of today with driverless cars Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks
to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing (叫车) services.
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon
emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施)
and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services,
considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people
become comfortable with the technology.
Policymakers should start thinking now about how to make sure the appearance of
driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to
develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
What is the author’s attitude to the future of self-driving cars
A ．Doubtful.
B ．Positive.
C ．Disapproving.
D ．Sympathetic.

8 ．By the end of the century, if not sooner, the world’s oceans will be bluer and greener
试卷第 8 页，共 11 页
thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called
phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create
colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to
the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a
climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model
projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean
changing.” she said, “but the type of phytoplankton is changing.”
And why does that matter Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said,
“but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
What is the main purpose of the passage
A ．To assess the consequences of ocean colour changes.
B ．To analyse the composition of the ocean food chain.

C ．To explain the effects of climate change on oceans.

9．Vast underwater meadows (草甸) of gently waving sea grass cover hundreds of miles up and down the West Coast. These blue-green fields perform a variety of important services. They
protect the shoreline from erosion, clear pollutants from the water and provide habitats for all
kinds of marine animals.
New research suggests sea grass meadows may also mitigate a serious consequence of
greenhouse gas emissions: the steady acidification of ocean waters. The study published in the journal Global Change Biology finds that sea grass forests can raise pH levels in coastal waters. As they perform photosynthesis (光合作用), they remove carbon dioxide from the water,
counteracting the acidifying effect of the gas.
“I think we are all very excited about it,” said lead study author Aurora Ricart, a scientist at the Bigelow Laboratory for Marine Sciences.
Ocean acidification is a side effect of rising carbon dioxide levels in the atmosphere. Some of this CO2 dissolves out of the air and into the sea, causing a chemical reaction that lowers the
water’s pH. Scientists sometimes refer to it as global warming’s “evil twin”—an invisible companion to climate change.
Ocean acidification can have harmful effects on marine organisms like shellfish and coral
by preventing them from properly forming the hard shells they need to survive. It’s a threat both to natural ecosystems and to shellfish fisheries around the world. The study presents a natural way to address the problem.
Researchers analyzed six years of data from sea grass meadows spanning more than 600
miles off the California coastline. It focused on the common eelgrass, one of the most widespread sea grass species on the West Coast. The authors claim it’s the largest, most comprehensive study of its kind.
According to the study, sea grass ecosystems can raise pH levels by more than 0.1 unit,
equivalent to about a 30% decrease in acidity. The effect isn’t constant. It comes in waves and is influenced by temperature, daylight, ocean currents and other factors that affect water chemistry
and sea grass photosynthesis rates. But the tempering influence on acidification can be lasting,
sometimes persisting for up to three weeks at a time. The study also shows that pH is higher in sea
试卷第 10 页，共 11 页
grass ecosystems, compared to nearby areas with no sea grass, about 65% of the time.
The study didn’t investigate the effects of higher pH on marine organisms — that’s a
question for future research. But there’s reason to believe these meadows may have a positive influence on shellfish and other ocean animals.
Why does the author write this passage
A ．To illustrate the serious situation of climate change.
B ．To present the living conditions of the underwater meadows.
C ．To emphasize the importance of research on marine pollution.
D ．To introduce a natural way to solve the problem of ocean acidification.
