1 . The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams（欺诈）. We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it’s too little, too late. By the time these ＂solutions"（解决方案）become widely available, scammers will have moved onto cleverer means. In the near future, it’s not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you’re hearing is actually real.

That’s because there are a number of powerful voice manipulation ( 处理 ) and automation technologies that are about to become widely available for anyone to use. At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.

These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches（数据侵入）of personal information has led to a situation where scammers can easily learn your mother’s name, and far more. Armed with this knowledge, they’re able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller’s, tricking you into "confirming" your address, mother’s name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.

We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications — using apps like FaceTime or WhatsApp, which can be tied to your identity.

Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

Which of the following would be the best title for the passage?

A．Where the Problem of Robocalls Is Rooted

B．Who Is to Blame for the Problem of Robocalls

C．Why Robocalls Are About to Get More Dangerous

D．How Robocalls Are Affecting the World of Technology

2 . Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December: Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario（情景）this century”.

A survey of scientists found that extreme weather events, food insecurity, and freshwater shortages might create global collapse. Of course, if you are a non-human species, collapse is well underway.

The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world’s most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.

The international scholars’ warning letter doesn’t say exactly what collapse will look like or when it might happen. Collapseology, the study of collapse, is more concerned with identifying trends and with them the dangers of everyday civilization. Among the signatories（签署者）of the warning was Bob Johnson, the originator of the “ecological footprint” concept, which measures the total amount of environmental input needed to maintain a given lifestyle. With the current footprint of humanity, “it seems that global collapse is certain to happen in some form, possibly within a decade, certainly within this century, ” Johnson said in an email.

Only if we discuss the consequences of our biophysical limits, the December warning letter says, can we have the hope to reduce their “speed, severity and harm”. And yet messengers of the coming disturbance are likely to be ignored. We all want to hope things will turn out fine. As a poet wrote,

Man is a victim of dope（麻醉品）

In the incurable form of hope.

The hundreds of scholars who signed the letter are intent（执着）on quieting hope that ignores preparedness. “Let’s look directly into the issue of collapse, ” they say, “and deal with the terrible possibilities of what we see there to make the best of a troubling future. ”

What can we learn from this passage?

A．The signatories may change the biophysical limits.

B．The author agrees with the message of the poem.

C．The issue of collapse is being prioritized.

D．The global collapse is well underway.

3 . Quantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor.

For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype ( 炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of dollars are now potentially available to quantum computing researchers.”

As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum.

After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum.

The company, he says, is closer than any other firm “by a very large margin ( 幅度 )” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparing what we are doing with others.”

Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson.

Regarding Johnson’s concerns, the author feels ________.

A．sympathetic

B．unconcerned

C．doubtful

D．excited

4 . Early fifth-century philosopher St. Augustine famously wrote that he knew what time was unless someone asked him. Albert Einstein added another wrinkle when he theorized that time varies depending on where you measure it. Today’s state-of-the-art atomic (原子的) clocks have proven Einstein right. Even advanced physics can’t decisively tell us what time is, because the answer depends on the question you’re asking.

Forget about time as an absolute. What if, instead of considering time in terms of astronomy, we related time to ecology? What if we allowed environmental conditions to set the tempo (节奏) of human life? We’re increasingly aware of the fact that we can’t control Earth systems with engineering alone, and realizing that we need to moderate (调节) our actions if we hope to live in balance. What if our definition of time reflected that?

Recently, I conceptualized a new approach to timekeeping that’s connected to circumstances on our planet，conditions that might change as a result of global warming. We’re now building a clock at the Anchorage Museum that reflects the total flow of several major Alaskan rivers, which are sensitive to local and global environmental changes. We’ve programmed it to match an atomic clock if the waterways continue to flow at their present rate. If the rivers run faster in the future on average, the clock will get ahead of standard time. If they run slower, you’ll see the opposite effect.

The clock registers both short-term irregularities and long-term trends in river dynamics. It’s a sort of observatory that reveals how the rivers are behaving from their own temporal frame (时间框架), and allows us to witness those changes on our smartwatches or phones. Anyone who opts to go on Alaska Mean River Time will live in harmony with the planet. Anyone who considers river time in relation to atomic time will encounter a major imbalance and may be motivated to counteract it by consuming less fuel or supporting greener policies.

Even if this method of timekeeping is novel in its particulars，early agricultural societies also connected time to natural phenomena. In pre-Classical Greece, for instance, people “corrected” official calendars by shifting dates forward or backward to reflect the change of season. Temporal connection to the environment was vital to their survival. Likewise, river time and other timekeeping systems we’re developing may encourage environmental awareness.

When St. Augustine admitted his inability to define time, he highlighted one of time’s most noticeable qualities: Time becomes meaningful only in a defined context. Any timekeeping system is valid, and each is as praiseworthy as its purpose.

The author raises three questions in Paragraph 2 mainly to________.

A．present an assumption	B．evaluate an argument
C．highlight an experiment	D．introduce an approach

5 . My name is Alice. Early last year, I was troubled by an anxiety that crippled ( 削弱 ) my ability to do anything. I felt like a storm cloud hung over me. For almost a year I struggled on, constantly staring at this wall that faced me. My perfectionist tendencies were the main root of this: I wanted to be perfect at whatever I did, which obviously in life is not possible, but it consumed me.

One day, I attended a presentation by wildlife conservationist Grant Brown at my high school. His presentation not only awed and inspired me, but also helped emerge an inner desire to make a difference in the world. I joined a pre-presentation dinner with him and that smaller setting allowed me to slowly build up my courage to speak one-on-one with him—an idea that had seemed completely impossible. This first contact was where my story began.

A month later, Brown invited me to attend the World Youth Wildlife Conference. Looking back, I now see that this would be the first in a series of timely opportunities that my old self would have let pass, but that this new and more confident Alice enthusiastically seized. Shortly after I received his invitation, applications to join the Youth for Nature and the Youth for Planet groups were sent around through my high school. I decided to commit to completing the applications, and soon I was a part of a growing global team of young people working to protect nature. Each of these new steps continued to grow my confidence.

I am writing this just six months since my journey began and I’ve realised that my biggest obstacle ( 障碍 ) this whole time was myself. It was that voice in the back of my head telling me that one phrase that has stopped so many people from reaching their potential: I can’t. They say good things come to those who wait; I say: grab every opportunity with everything you have and be impatient. After all, nature does not require our patience, but our action.

What can we learn from this passage?

A．Practice makes perfect.	B．Patience is a cure of anxiety.
C．Action is worry’s worst enemy.	D．Everything comes to those who wait.

9 . Hi! My name is Adam and I’m a freshman at senior high school. Going from junior high school to senior high school is a really big challenge. The first week was a little confusing.

First, I had to think very carefully about which courses I wanted to take. The school adviser (辅导员) helped me choose the suitable ones: maths, English, chemistry, world history, and Chinese. I know that Chinese is a very difficult language, but I hope to be fluent (流利的) when I graduate. My adviser recommended (建议) that I should sign up for advanced literature (文学) because I like English and I’m good at it.

I had to choose extra-curricular activities, too. I tried to join the school football team, but the coach told me that I didn’t play well enough. Obviously, I was unhappy, but I won’t quit (放弃). I’ll find a way to improve on my own so that I can make the team next year. I joined a volunteer club instead. Every Wednesday, we work at a soup kitchen (流动厨房) and hand out food to homeless people in the community.

I know I’ll have to study harder as a senior high school student and get used to being responsible for a lot more. I’m a bit worried about keeping up with the other students in my advanced course, and it’ll be quite difficult to get used to all the homework. Still, I’m happy to be here. Studying hard isn’t always fun, but I’ll be well prepared for university or whatever else comes in the future.

10 . Born with severe hearing loss, Li has found her way to communicate with the world—through painting.

Before learning to paint, Li always felt lonely in a silent world. She knew she was different from her peers because she could not hear. But a painting class in primary school opened for her a door to creativity and a way of expression.

“I still remember my first mural, which was to help a kindergarten to design and paint its wall,” Li says. “The project made me realize how happy I was immersing myself into painting.”

To pursue her passion for art, Li went to study advertising design at a vocational and technical school. “Painting brushes can help me create a colorful world in my imagination, telling my thoughts on paper, instead of through voices,” Li said.

Graduating from college in 2005, Li got a job as a typist at a public institute. But she could not communicate well with her other colleagues. Her husband understood how she felt because he lost his hearing due to medication when he was 1 year old. He is also an art lover. In March 2016, under her husband’s suggestion, Li quit her job and joined her husband’s company, which specializes in 3D wall and ground paintings.

Wall painting is a demanding job because it requires people to work outdoors, whether in extremely cold or hot weather. As all the people are hearing-impaired in their company, communication with clients is the most common challenge that the team faces.

Now in many parks and scenic spots, the couple have created large-scale murals and interactive pavement painting that make onlookers a part of the drawings.

“My husband and I want to introduce painting to more people like us and help them find their own way to make a living,” Li says. Now Li has an apprentice who just graduated from college. While coaching the newcomer, Li is exploring her own style and hopes to become an illustrator and open her own exhibition one day.

“They’re energetic young people with a passion to create new things, and you can feel that in their paintings,” one of their clients said. “They’re also a professional, dedicated team, often working late into the night on the designs for us.”

Li hopes that their stories can encourage more hearing-impaired people to build their own careers and achieve their goals, regardless of how tough it may be.

What does the passage mainly tell us?

A．One is never too old to learn.

B．Failure is the mother of success.

C．Accepting what you have makes you happy.

D．Nothing is impossible to the man who will try.
