1 . Predicting extreme weather events is a tricky business. Changing climate conditions have increased the frequency of severe storms, floods, and heatwaves, along with larger wildfires. As a result, scientists are using artificial intelligence (AI) techniques for more accurate forecasts that help to minimize damage and save lives.

Researchers at Pennsylvania State University have worked together with meteorologists (气象学家) to analyze more than 50,000 weather satellite images to quickly identify storms. They found comma-shaped cloud formations that often lead to severe weather such as hail, blizzards, high winds, and thunderstorms.

Computers were then taught using computer vision and machine learning to automatically detect these clouds from satellite images, with almost 100 percent accuracy, in less than a minute. By refocusing meteorologists’ attention on potential storm cloud formation the AI tool helped predict 64 percent of severe weather events and beat established detection systems.

Expensive supercomputers are often used to process vast amounts of data needed for accurate weather prediction. But powerful Al methods can run on smaller computers. Climate risk and planning company ClimateAI uses a technique to downscale global weather forecasts to a local scale, cutting down on costs and computing power.

It uses a machine learning technique that pits two neural networks against each other. The neural networks - designed to work like neurons connected in the brain-fight and train each other using global weather data until they get a result.

Using this method ClimateAI researchers generate highly accurate and inexpensive local forecasts for hours or days ahead. And because it is not as costly, it allows poorer countries affected by climate change to use forecasts to change the way they farm, build bridges, roads, or homes, and adapt to extreme weather.

Average costs associated with extreme weather events in the United States have increased steadily since 1980. These have costly impacts on cities’ basic services, infrastructure, housing, human livelihoods, and health. AI helps us to calculate that risk and can be used as a preventive measure.

3 . Many of our family traditions centered around food. We’d gather in the kitchen for every birthday and holiday and enjoy delicious food. My grandparents always held Christmas dinner, which included chicken cacciatore, sausage, meatballs and salad. But right before we sat down to eat, my grandmother would pull me aside to show me the dish she made just for me: fresh pasta (意大利面) with tomato sauce.

It was a simple dish, but to me it was warm food that filled me with happiness. But more than that, it made me feel like I belonged. I was a shy kid and, in many situations, I felt ignored. And here was my grandmother, showing me that I mattered.

Years went by; I moved away and got married. I’d visit throughout the years and my grandmother would serve up a plate of pasta.

When my daughter was born in 2020, for the first time in my life I wasn’t about to make the trip back home for Christmas. I cooked my family’s traditional foods and my husband and I had a big meal that included, of course, fresh pasta. I had a video call with my grandmother and showed her the pasta. Shortly after the holidays she passed away unexpectedly.

It seemed so unfair that my grandmother passed away soon after I became a parent. I’d hold my daughter and think about how I could tell her what an amazing great-grandmother she had.

In my sadness I came to an answer: food. Late at night after my daughter had gone to bed, I’d go to the kitchen and learn how to make fresh pasta, cooking my grandmother’s recipes. Before long I started experimenting, making a bit changes to classic recipes. When my daughter got a little older, I began making special dishes for her with my grandmother’s flavors in mind.

I know that no matter how hard I try, my daughter will never have a bowl pasta with sauce exactly like the ones my grandmother would make for me. While that makes me sad, she’ll still get to have my pasta sauce. I know there’re two things she’ll never lack for in this life: pasta and love.

1. What did the author say about her grandmother’s homemade pasta?

A．It was a special birthday gift for her.	B．It brought her a sense of belonging.
C．It was loved by every family member.	D．It took a lot of time and energy to prepare.

D．She didn’t have a chance to eat her grandmother’s pasta.

3. Why did the author learn to make fresh pasta late at night?

A．To honour her grandmother.	B．To give her daughter a surprise.
C．To meet her grandmother’s wish.	D．To be a role model for her daughter.

4. What can we learn about the author’s pasta sauce?

A．It isn’t easy to make.	B．It isn’t to her daughter’s liking.
C．It tastes exactly the same as her grandmother’s.	D．It shows her love for her daughter.

5. What’s the best title for the text?

4 . A recent global study, which surveyed 10,000 young people from 10 countries, showed that nearly 60 percent of them were extremely worried about the future state of the planet. The report, which was published in The Lancet, also showed that nearly half of the respondents said that such distress affected them daily, and three quarters agreed with the statement that “the future is frightening.” This, along with many other studies, shows clearly that climate change is not just a threat to the environment that we inhabit. It also poses a very real threat to our emotional well-being. Psychologists have categorized these feelings of grief and worry about the current climate emergency, a common occurrence among youth today, under the label of “eco-anxiety”.

Eco-anxiety doesn’t just affect young people. It also affects researchers who work in climate and ecological science, burdened by the reality depicted by their findings, and it affects the most economically marginalized (边缘化的) across the globe, who bear the damaging impacts of climate breakdown.

In 2024, eco-anxiety will rise to become one of the leading causes of mental health problems. The reasons are obvious. Scientists estimate that the world is likely to breach safe limits of temperature rise above pre-industrial levels for the first time by 2027.

In recent years, we’ve seen wildfires tear through Canada and Greece, and summer floods ruin regions in Pakistan that are home to nearly 33 million people. Studies have shown that those impacted by air pollution and rising temperatures are more likely to experience psychological distress.

To make matters worse, facing climate crisis, our political class is not offering strong leadership. The COP28 conference in Dubai will be headed by an oil and gas company executive. In the UK, the government is backtracking on its green commitments.

Fortunately, greater levels of eco-anxiety will also offer an avenue for resolving the climate crisis directly. According to Caroline Hickman, a researcher on eco-anxiety from the University of Bath, anyone experiencing eco-anxiety is displaying entirely natural and rational reactions to the climate crisis. This is why, in 2024, we will also see more people around the world join the fight for climate justice and seek jobs that prioritize environmental sustainability. Campaigners will put increased pressure on fossil fuel industries and the governments to rapidly abandon the usage of polluting coal, oil, and gas.

It’s now clear that not only are these industries the main causes for the climate crisis, they are also responsible for the mental health crisis, which is starting to affect most of us. Eco-anxiety is not something we will defeat with therapy, but something we will tackle by taking action.

6 . Artificial intelligence is almost twice as accurate as a biopsy (活组织检查) at judging the aggressiveness of some cancers, experts say. Cancer kills 10 million people globally every year, according to the WHO. But for patients the disease can be prevented if detected instantly and dealt with quickly.

A recent study suggested an AI algorithm (算法) was far better than a biopsy at correctly grading the aggressiveness of sarcomas (肉瘤), a rare form of cancer. Researchers hope AI will improve outcomes for patients by giving doctors a more accurate way of grading tumours (肿瘤). Because high-grade tumours can indicate aggressive disease, the tool could help ensure those high-risk patients are identified more quickly and treated instantly. Low-risk patients could also be spared unnecessary treatments, follow-up scans and hospital visits.

Researchers say the algorithm could be applied to other types of cancer in future. The team specifically looked at retroperitoneal sarcomas, which develop at the back of the abdomen and are difficult to diagnose (诊断) and treat due to their location. They used CT scans from 170 patients with the two most common forms of retroperitoneal sarcoma — leiomyosarcoma and liposarcoma. Using data from these scans they created an AI algorithm, which was then tested on 89 patients in other countries. In grading how aggressive the tumour was, the technology was accurate in 82% of the cases, while biopsies were 44%.

AI could also recognize leiomyosarcoma and liposarcoma in 84% of sarcomas tested, while radiologists were able to identify them in 65% of the cases. Christina Messiou, the study leader, said: “We’re incredibly excited by the potential of this state-of-the-art technology, which could lead to patients having better outcomes through faster diagnosis. As patients with retroperitoneal sarcoma are routinely scanned with CT, we hope this tool will eventually be used globally, ensuring that not just specialist centres can reliably identify and grade the disease.”

Richard Davison, chief executive of Sarcoma UK, said the results looked “very promising”. He added: “People are more likely to survive sarcoma if diagnosed early. One in six people with sarcoma cancer wait more than a year to receive an accurate diagnosis, so any research that helps patients receive better treatment and support is welcome.”

8 . Researchers have long known that the brain links kinds of new facts, related or not, when they are learned about the same time. For the first time, scientists have recorded routes in the brain of that kind of contextual memory, the frequent change of thoughts and emotions that surrounds every piece of newly learned information.

The recordings, taken from the brains of people awaiting surgery for epilepsy (癫痫), suggest that new memories of even abstract facts are encoded (编码) in a brain-cell order that also contains information about what else was happening during and just before the memory was formed.

In the new study, doctors from the University of Pennsylvania and Vanderbilt University took recordings from a small piece of metal implanted in the brains of 69 people with severe epilepsy. The implants allow doctors to pinpoint the location of the flash floods of brain activity that cause epileptic happening. The patients performed a simple memory task. They watched a series of nouns appear on a computer screen, and after a brief disturbance recalled as many of the words as they could, in any order. Repeated trials, with different lists of words, showed a predictable effect: The participants tended to remember the words in groups, beginning with one and recalling those that were just before or after.

This pattern, which scientists call the contiguity effect, is similar to what often happens in the card game concentration, in which players try to identify pairs in a row of cards lying face-down. Pairs overturned close are often remembered together. The way the process works, the researchers say, is something like reconstructing a night’s activities after a hangover: remembering a fact (a broken table) recalls a scene (dancing), which in turn brings to mind more facts, like the other people who were there.

Sure enough, the people in the study whose neural (神经) updating signals were strongest showed the most striking pattern of remembering words in groups. “When you activate one memory, you are reactivating a little bit of what was happening around the time the memory was formed, and this process is what gives you that feeling of time travel,” said Dr Michael J. Kahana.

9 . Nowadays, the world is slowly becoming a high-tech society and we are now surrounded by technology. Facebook and Twitter are innovative tools; text messaging is still a somewhat existing phenomenon and even e-mail is only a flashing spot on the screen when compared with our long history of snail mail. Now we adopt these tools to the point of essentialness, and only rarely consider how we are more fundamentally affected by them.

Social media, texting and e-mail all make it much easier to communicate, gather and pass information, but they also present some dangers. By removing any real human engagement, they enable us to develop our abnormal self-love without the risk of disapproval or criticism. To use a theatrical metaphor (隐喻), these new forms of communication provide a stage on which we can each create our own characters, hidden behind a fourth wall of tweets, status updates and texts. This unreal state of unconcern can become addictive as we separate ourselves a safe distance from the cruelty of our fleshly lives, where we are imperfect, powerless and insignificant. In essence, we have been provided not only the means to be more free, but also to become new, to create and project a more perfect self to the world. As we become more reliant on these tools, they become more a part of our daily routine, and so we become more restricted in this fantasy.

So it is that we live in a cold era, where names and faces represent two different levels of closeness, where working relationships occur only through the magic of email and where love can start or end by text message. An environment such as this reduces interpersonal relationships to mere digital exchanges.

Would a celebrity have been so daring to do something dishonorable if he had had to do it in person? Doubtful. It seems he might have been lost in a fantasy world that ultimately convinced himself into believing the digital self could obey different rules and regulations, as if he could continually push the limits of what’s acceptable without facing the consequences of “real life.”

1. What can we know about new communication tools?

A．Destroying our life totally.	B．Posing more dangers than good.
C．Helping us to hide our faults.	D．Replacing traditional letters.

2. What is the potential threat caused by the novel communication tools?

A．Sheltering us from virtual life.	B．Removing face-to-face interaction.
C．Leading to false mental perception.	D．Making us rely more on hi-tech media.

3. What can be inferred from the last two paragraphs?

A．Technologies have changed our relationships.

B．The digital world is a recipe for pushing limits.

C．Love can be better conveyed by text message.

D．The digital self need not take responsibility.

4. Which of the following is a suitable title for the text?

A．Addiction to the Virtual World	B．Cost of Falling into Digital Life
C．Interpersonal Skills on the Net	D．The Future of Social Media
