5 . Until we start to lose our balance, we barely notice that it’s there at all. “It starts for a lot of people with simple stuff,” says Dr Anna Lowe, an expert on healthy ageing and physical activity. “    1     It’s easy to either miss the signs or just put it down to ageing — but it really is something you can affect.”

The key, it is increasingly becoming clear, is to address the decline before it gets serious: and that can happen earlier than you might think.

What is balance? Technically, it’s the complex interaction of several different systems in your body — from muscles, nerves, eyesight and the inner ear to the sensory system that lets you recognise where your body is touching the ground, along with movement receptors within your joints that tell you where your body is in space.     2    

A lack of balance is, globally, associated with serious health problems. Earlier this year, the British Journal of Sports Medicine published the results of a decade-long study involving more than 1,700 middle-aged participants, which concluded that an inability to balance was associated with an almost twofold increase in risk of death.

“    3    ” agrees Lowe, an associate professor researching strength and balance in midlife. “Older women are far less active than older men, and general activity, just moving around and doing stuff, affects balance a lot. Single-legged movements, such as walking lunges, are a great test of dynamic (动态的) balance, but even bilateral movements, like squats (深蹲), can provide a challenge.”

    4     Resistance exercise, whether that means lifting weights or hiking with a backpack, comes with a host of other proven health benefits, from improved bone density to a reduced risk of Alzheimer’s. As Locker puts it: everyone’s told to save money for their retirement, and nobody’s taught to save their balance. But both are difficult to get back once they’re gone.

A．Early interventions are key, so you’ve got to stay active.

B．Perhaps surprisingly, those who deal with it have struggled to settle on a single definition.

C．It’s not something we’re born with, but also it’s not something we learn, but an ability that we gain early and lose over time.

D．For some people. just try to build in an element of balance and muscle strengthening.

E．Maybe you used to be able to quickly stand on one leg to put a shoe on, and you’ve stopped doing that at some point.

F．Whatever activity you choose, the lesson is to work on your balance before you need to, not when it becomes an issue.

6 . Could your dog be prone to a fatal disease? Is your new shelter pup part beagle or boxer? Many pet owners seek answers to these questions, and as a result, direct-to-consumer dog DNA testing is booming.

Human interfering with dog DNA has long been the driving factor behind dogs’ breed diversity — or lack thereof. But a dog’s DNA can also be used to confirm their lineage (血统) or identify their breed, a boon for pet owners on the lookout for breed-specific health or behavioral challenges or those looking to confirm their dog really has the heritage claimed by a breeder or seller. During DNA analysis, labs sequence the dog’s DNA and look for similarities with a dataset of identified dog breeds.

But breed identification isn’t as simple as it might seem. In a study published in the Journal of the American Veterinary Medical Association last month, scientists looked into the accuracy of breed prediction in commercially available DNA tests that required a photo of the dog in addition to its DNA sample. The results were mixed, says Casey Greene, a professor who co-authored the study.

“Most tests could accurately distinguish the breed of purebred dogs,” says Greene. But the analysis suggested that some testing companies might rely on the photo more than the dog’s actual genetics — and revealed big differences between companies’ business practices and the genetic datasets they use to determine dog breeds.

The researchers submitted photos and DNA of 12 purebred dogs to a total of six commercial canine (犬的) ancestry identification services. Since each pup was purebred and possessed extensive American Kennel Club paperwork, the researchers knew their breed conclusively—but in some cases they provided a photo of a different dog to see if the photo influenced the DNA results. One of the companies misidentified a purebred Chinese crested dog — almost entirely hairless — as a long-haired Brittany spaniel, seemingly based on the photo alone. The other five did identify the registered breed correctly, but often gave different predictions for other “ancestor” breeds in dogs whose DNA suggested mixed breeding in prior generations. The researchers concluded that veterinarians and pet owners alike should “approach direct-to-consumer tests with caution” given the lack of industry standardization and at least one company’s reliance on photographs instead of DNA analysis.

Despite these concerns, though. dog DNA seems headed for a golden age — and the insights revealed through further study of Fido’s genome (基因组) have already reached far beyond the doghouse. Domesticated dogs have emerged as surprising superstars in medical research that benefits humans. According to researchers, that’s just the beginning. With implications ranging from entertaining to consequential, there’s no telling what dog DNA will continue to unleash.

IN CONTEXT BRANCH Geology BEFORE 6th century BCE The Greek thinker Thales of Miletus notes magnetic rocks, or lodestones (天然磁石). 1st century CE Chinese diviners make primitive compasses with iron spoon that can turn around to point south. 1269 French scholar Pierre de Maricourt sets out the basic laws of magnetic attraction, repulsion, and poles. AFTER 1824 French mathematician Siméon Poisson models the forces in a magnetic field. 1940s American physicist Walter Maurice Elsasser attributes Earth’s magnetic field to iron swirling in its outer core as the planet rotates. 1958 Explorer 1 space mission shows Earth’s magnetic field extending far out into space.

By the late 1500s, ships’ captains already relied on magnetic compasses to maintain their course across the oceans. Yet no one knew how they worked. Some thought the compass needle was attracted to the North Star, others that it was drawn to magnetic mountains in the Arctic. It was English physician William Gilbert who discovered that Earth itself is magnetic. Stronger reasons are obtained from sure experiments and demonstrated arguments than from probable conjectures (推测) and the opinions of philosophical speculators. William Gilbert Gilbert’s breakthrough came not from a flash of inspiration, but from 17 years of careful experiment. He learned all he could from ships’ captains and compass makers, and then he made a model globe, or “terrella,” out of the magnetic rock lodestone and tested compass needles against it. The needles reacted around the terrella just as ships’ compasses did on a larger scale—showing the same patterns of declination (pointing slightly away from true north at the geographic pole, which differs from magnetic north) and inclination (tilting down from the horizontal toward the globe). Gilbert concluded, rightly, that the entire planet is a magnet and has a core of iron. He published his ideas in the book De Magnete (On the Magnet) in 1600, causing a sensation. Johannes Kepler and Galileo, in particular, were inspired by his suggestion that Earth is not fixed to rotating celestial spheres, as most people still thought, but is made to spin by the invisible force of its own magnetism.

1. Before the 16^th century, how did captains navigate across oceans?

A．The North Star navigated their ships.

B．The magnetic mountains in the Arctic guided their journey.

C．Magnetic compasses helped them maintain the course.

D．The forces in a magnetic field attracted the ships.

2. How did William Gilbert find out the fact that Earth itself is magnetic?

A．Through trials and errors.

B．Through some personal philosophical speculation.

C．By acquiring some flash inspiration.

D．By studying the ideas of some philosophers.

3. Which of the following statement might Galileo agree with?

A．The earth stays still.

B．Gilbert successfully refuted the laws of magnetic attraction.

C．Gilbert’s findings and conclusions are sensational.

D．The earth has its own magnetic field.

8 . My husband and I live near San Luis Obispo, California, close to the beach. In November 2023, during the humpback whale migration, we kayaked (划皮划艇) out to watch the wildlife. We were in awe watching these graceful whales breach and spray through their blowholes.

At the time, my friend Liz was staying with us. Initially, she refused to join us on the water, fearing the kayak would overturn among the whales. After some cajoling (劝说) she finally agreed to join me. The following morning, we set out early and had our first whale sighting just past the pier: two humpbacks swimming toward us. How amazing to be that close to a creature that size, I thought as the whales dipped under the waterline.

When whales go down after breaching, they leave what looks like an oil slick on the water. I figured if we paddled toward that spot, we’d be safe from the whales, since they’d just left. We followed them at a distance — or what I thought was a distance. I later found out that it’s recommended to keep 300 feet away. We were more like 60 feet away.

Suddenly, we were surrounded by jumping silverfish fleeing from the whales. Before we could react, our kayak was lifted out of the water about six feet, bracketed by massive jaws. Liz and I slipped out of the kayak into the whale’s mouth. As the whale’s mouth closed, I felt the creature begin to dive and had no idea how deep we’d be dragged. Still, I didn’t panic. I just kept thinking. I’ve got to fight this. I’ve got to breathe.

Whales have enormous mouths but tiny throats. Anything they can’t swallow they spit right out. That included us. As soon as the whale dipped underwater, it ejected us, and we popped back up onto the surface about a foot apart. The entire ordeal lasted only about 10 seconds.

Other kayakers rushed to our aid, shocked to see us alive. But I am much more aware of the power of nature and the ocean than I was before. Liz was shaken up, comparing the ordeal to a near-death experience, and she says her whale-watching days are over. But even she had to laugh when she got home that afternoon and realized she’d brought back a souvenir. When she pulled off her shirt, six silverfish flopped out.

1. Which of the following statements is TRUE according to the passage?

A．At first, Liz was hesitant to go on the kayaking trip because she was not interested in whale watching.

B．If Liz and I had maintained a distance of 300 feet from the whales, we might have avoided the subsequent danger.

C．Liz and I slipped into the whale’s mouth because jumping silverfish overturned our kayak.

D．Liz is likely to go on another whale-watching trip someday because she found a precious souvenir from this kayaking.

2. How did the narrator feel during the whale encounter?

A．Terrified and panicked.	B．Disoriented underwater
C．Calm and focused.	D．Regretful about going kayaking.

3. The underlined word “ordeal” in Paragraph 5 probably means____.

A．a challenging or difficult experience	B．a thrilling experience
C．a surprising encounter	D．a joyful adventure

4. What would be the best title of this passage?

A．How to Survive a Whale Attack	B．Respecting the Power of Nature
C．A Day at San Luis Obispo Beach	D．I Survived Being Swallowed By a Whale

Does technology replace more jobs than it creates? What is the     1     balance between these two things? Until now, that has not been measured. But a new research project led by MIT economist David Autor has developed an answer, at least for U.S. history since 1940. The study uses new methods to examine how many jobs have been lost to machine     2    , and how many have been generated through “augmentation (增强),” in which technology creates new tasks. Overall, the study finds, and particularly since 1980, technology has replaced more U.S. jobs than it has generated.

“There does appear to be a faster rate of automation, and a slower rate of augmentation, in the last four decades. from 1980 to the present, than in the four decades     3    .” says Autor. However, that finding is only one of the study’s     4    . The researchers have also developed an entirely new method for studying the issue, based on an analysis of thousands of U.S. census job categories in relation to a(n)     5     look at the text of U. S. patents over the last century. That has allowed them, for the first time, to quantify the effects of technology over both job loss and job creation.

The study finds that overall, about 60 percent of jobs in the U.S. represent new types of work, which have been created since 1940. To determine this, Autor and his colleagues     6     through about 35,000 job categories, tracking how they emerge over time. They also used natural language processing tools to analyze the text of every U.S. patent filed since 1920. The research examined how words were “embedded” in the census and patent documents to     7     related passages of text. That allowed them to determine links between new technologies and their effects on employment.

From about 1940 through 1980, for instance, jobs like elevator operator and typesetter tended to get automated. But at the same time, more workers filled roles such as shipping and receiving clerks, buyers and department     8    , and civil and space engineers. From 1980 through 2018, the ranks of cabinetmakers and machinists, among others, have been     9     by automation, while industrial engineers, and operations and systems researchers and analysts, have enjoyed growth.

Ultimately, the research suggests that the negative effects of automation on employment were more than twice as great in the 1980-2018 period as in the 1940-1980 period. There was a more     10    , and positive, change in the effect of augmentation on employment in 1980-2018, as compared to 1940-1980.

In the fall of 1903, O. Henry was living in a room at the small Hotel Marty in New York City. He had published a few stories in local magazines, but was still relatively unknown when editors at the New York World newspaper sent a young reporter     1     (track) down this mysterious writer. By the next day, O. Henry had an agreement with the newspaper to write one story a week for the magazine section of their Sunday edition. The World had     2     (large) daily circulation in the world, and O. Henry’s stories about New York life became immensely popular. By the time he left the newspaper after less than three years, O. Henry had established his reputation     3     a gifted storyteller and master of surprise endings.

O. Henry was the pen name used by William Sydney Porter, who was born in North Carolina. At the age of twenty, he moved to Texas.     4     he held a variety of jobs, eventually becoming a bank teller. He married and became a reporter and columnist for the Houston Post. After a few years, his wife     5     (diagnose) with a serious infectious disease, and he was accused of illegally taking the money of the bank where he worked. Some people have claimed     6     he was stealing money to help pay his wife’s medical bills. O. Henry fled to Central America, but his wife was too ill to accompany him. Months later,     7     her condition worsened, he returned and turned himself in to the police. His wife soon died, and O. Henry spent three years in prison in Ohio. It was during his time in prison that he began writing the stories that would make him famous. W. S. Porter     8     (emerge) from prison as O. Henry.

In 1902 O. Henry moved to New York City and started trying to sell his stories. In a few years his luck changed for the better, and his position with the New York World helped make him a     9     (celebrate) author. He published more than three hundred stories and gained worldwide acclaim. O. Henry’s writing is admired for its colorful and realistic depictions of the everyday lives of New Yorkers. His stories are known for their plot twists and surprise endings. In fact, O. Henry’s own life ended with a “twist” — his funeral was somehow scheduled in the same church at the same time as someone else’s wedding! The O. Henry Award     10     (honor) the authors of the best stories printed each year in American magazines.
