21、Some people get worried when faced with simple math problems. And they may rely more heavily on certain brain circuits than people who do not experience such math anxiety. That’s the finding of a new study. Using a different mental approach might help explain why people with math anxiety struggle more with complex problems.
To figure out what was going on, researchers placed adults in a brain-scanning device. Called a functional magnetic resonance (磁共振) imaging machine, it measures blood flow in the brain. This lets researchers see which brain regions are active at a particular point in time. For the new study, the study recruited (招募) people with and without math anxiety. All of the adults were asked to answer whether simple math problems were correct or not. Both groups had similar response time. Each group also was equally accurate. The brain scans, however, turned up some differences.
In people who weren’t anxious about math, there was less activity in one brain region. It is called the frontoparietal (额顶的), attention network. It is involved in working memory and the solving of problems.
People who relied on this circuit less were probably getting ahead by automating simple math, said Hyesang Chang. She’s a cognitive neuroscientist who works at the University of Chicago in Illinois. She reported her team’s findings on March 25 here at the annual meeting of the Cognitive Neuroscience Society.
People who get anxious over math showed more varied brain activity overall. That led Chang to consider that these people might be handling math problems in a different way. Their brains might be using a variety of approaches—and in ways that use more brain resources. This general approach works fine for simple math, she said. But the brains of those with math anxiety might get maxed out when the math is more challenging.
【1】According to the text, people who experience math anxiety may ________.
A. have better working memory
B. solve math problems inaccurately
C. suffer more injuries in face of complex problems
D. have more activity in the frontoparietal attention network
【2】Researchers did the study with the help of ________.

A. How to learn math better
B. How does people’s brain react to math problems?
C. What researchers find about people’s brain
D. What should people do to avoid math anxiety?
22、 We all agree, surely – memorizing poetry is a good thing, and children ought to do it. But people do object. At least, they object to the idea that children should be forced to learn poetry. They tend to be people like Michael Rosen. Rosen has more practical objections to children having to learn poetry by the government’s order. Actually, Rosen is all for learning poetry, “when it feels right”, which is, he says, “one of those vague phrases much hated by people in authority and yet it is at the heart of good teaching”.
He’s onto something about the timing, but that doesn’t mean policymakers are wrong to insist on pupils learning poetry. The problem is that some influential educationists have come to see learning by heart as a waste of time when tomorrow’s adults will want skills more than information.
Let’s come to the most important objectors–children. Their objection tends to come in the least offensive form. It comes in the question: “Why are we doing this?” It’s a worthwhile inquiry. I teach at Sherborne School, where boys do learn poetry; and luckily there’s time in our lessons to answer that question.
Here’s one of the answers I give. There’ll be one time when your good friend is going to introduce you to someone with whom he wants to spend the rest of his life. There’ll be a ceremony to honour this union, and words will be very important. You’re likely to be the one who has to stand up and say, “Let me not to the marriage of true minds/ Admit impediment…” And when you do that, you’re going to be speaking for everyone in the room. Now, everybody breathes sigh of relief.
Learning poetry and reciting poetry forces us to think of it in this public way. However mysterious and intimate poetry seems, we need to remember it’s something we also share, and offer each other. So take some, and pass it on.
【1】What does the underlined word “it” in the first paragraph refer to?
A.The right timing.
B.The poetry with vague phrases.
C.The government’s order.
D.The natural way to learn poetry.
【2】Which of the following would be favored by some influential educationists?
A.To guide children how to recite poetry.
B.To instruct children on how to get information.
C.To teach students real life skills for the future.
D.To force children to obey the government policy.
【3】As for the children’s question, the teacher should _______.
A.consider it offensive B.take it seriously C.dismiss it as worthless D.discuss it after class
【4】What’s the writer’s attitude towards poetry learning?
A.Objective. B.Supportive. C.Critical D.Disapproving.
23、Reshaping the world for a fossil fuel-free future means working quickly. Climate scientists say carbon emissions must stop by 2025 to minimize environmental damage. And by designing computational materials together with makers who can build and test them quickly, scientists can rapidly develop technologies like more powerful solar cells and car batteries.
Michael is the name of a supercomputer devoted to just one task―discovering the ultimate battery system. Researchers at University College London will use Michael to digitally build and test prototypes (原型) in every new material and type of cell possible to improve battery life, performance and price.
Finding a resilient (弹性的) design for solid-state batteries would be a huge breakthrough for electric vehicles and energy storage. Lighter, longer-lasting and cheaper solid-state technology could vastly improve vehicle range and charging time. And the energy from solar and wind power could be more efficiently stored until ready for use.
Scientists working in the US and the UK led the way in the 1970s in developing the lithium-ion (锂离子) battery used in today’s electric cars, laptops and cameras, But commercial units were only developed once the Japanese electronics giant pushed the technology forward for mass production. Partnerships between companies and universities could ultimately crack solid-state battery design. Oxford University and some companies are looking to win the international race to create a durable product. But they are only one among many.
Replacing liquid used in lithium-ion batteries with a solid conductor may take large digital processing. Electric vehicle makers are working with a computer giant to find successful designs that may include cheap and plentiful materials found in seawater. An electric vehicle maker is partnering with NASA to open a solid-state battery plant that uses no rare or expensive metals. The plan is to create a large database of materials that can be mixed and matched for the best combinations.
But computational materials may be needed in virtually every industry. And by rapidly classifying millions of substances on their ability to conduct electricity, their toughness, or the way they reflect light, AI and supercomputers can speed up the process of creating materials for just about anything.
【1】What message does paragraph 1 convey?
A.It’s too fast to design computational materials.
B.It’s too late to reshape the fossil fuel-free world.
C.Developing green energy can reduce carbon emissions.
D.Developing technology can speed up carbon emissions.
【2】What are solid-state batteries expected to be like?
A.Heavy and solid.
B.Light but breakable.
C.Less-costly and workable.
D.Expensive but efficient.
【3】Why does the author mention Oxford University in paragraph 4?
A.To show the weakness of mass production.
B.To show the good trend of the cooperation.
C.To show the difficulty of the battery design.
D.To show the development of British technology.
【4】What can be the best title for the text?

B.Companies and NASA Will Push Technology Forward
C.Electric Vehicle Makers Are Struggling to Solve Air Pollution
D.Supercomputers and AI Can Create Future Low-carbon Industries
24、Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt—including the beds (though you’ll sleep on regular mattresses (床垫) and blankets).The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.
Green Magic Nature Resort
Where: Vythiri, India
How much: About $240 a night
Why it’s cool: Ridding a pulley(滑轮)-operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window—there is no glass!—you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast—the hotel will send it up on the pulley-drawn “elevator”.
Dog Bark Park Inn B&B
Where: Cottonwood, Idaho
How much: $92 a night
Why it’s cool: This doghouse isn’t just for the family pet. Sweet Willy is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side. You can relax in the main bedroom, go up a few steps of the loft in Willy’s head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant outside.
Gamirasu Cave Hotel
Where: Ayvali, Turkey
How much: Between $130 and $475 a night.
Why it’s cool: This is caveman cool! Experience what it was like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool, about 65℉in summer.(Don’t worry—there is heat in winter.)

25、Many early approaches to language technology — and particularly translation — get _________ in a conceptual dead end: the rules-based approach. In translation, this meant trying to write rules to analyze the text of a sentence in the language of _________, breaking it down into a sort of abstract “interlanguage” and rebuilding it according to the rules of the target language. These approaches showed early _________. But language is full of ambiguities and exceptions, so such systems were hugely complicated and easily _________ when tested on sentences beyond the simple set they had been designed for.
Nearly all language technologies began to get a lot better with the application of _________ methods, often called a “brute force” approach. This relies on software scanning vast amounts of data, looking for patterns and learning from precedent. _________, in parsing language (breaking it down into its grammatical components), the software learns from large bodies of text that have already been parsed by humans. It uses what it has learned to make its best _________ about a previously unseen text. In machine translation, the software scans millions of words that have already been translated by humans, again looking for patterns. In speech reorganization, the software learns from a body of recordings and the transcriptions made by humans.
Thanks to the growing power of processors, falling prices for data storage and, most crucially, the explosion in available data, this approach eventually _________. Mathematical techniques that had been known for decades came into their own, and big companies with _________ to enormous amounts of data were ready to benefit.
The final advance, which began only about five years ago, came with the arrival of deep learning through digital neural networks (DNNS). These are often claimed to have qualities similar to those of the __________: “neurons” are connected in software, and connections can become stronger or weaker in the process of learning. __________, Nils Lenke, head of research for a language technology company, explains matter-of-factly that “DNNs are just another kind of mathematical model,” the __________ of which had already been understood for decades. What changed was the hardware being used.
Almost by chance, DNN researchers discovered that the graphical processing units (GPUs) __________ to produce graphics in applications like video games were also brilliant at handling neural networks. The technique has already produced big leaps in quality for all kinds of deep learning, including decoding handwriting, recognizing faces and classifying images. Now they are helping to improve all manner of language technologies, often bringing enhancements of up to 30%. That has shifted language technologies from being __________ in a pinch to being really rather good. But so far no one has quite __________ what will move it forward from being merely good to reliably great.
