1 . Metin Sitti at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, and his colleagues have developed tiny robots called “microrollers” that can carry cancer drugs and selectively target human breast cancer cells. The team drew inspiration for the design of the robots from white blood cells in the human body, which can move along the walls of blood vessels (血管) against the direction of blood flow.
The microrollers are round and made from glass microparticles. One half of the robot was coated with a thin magnetic nanofilm (磁性纳米膜) made from nickel and gold. The other half was coated with the cancer drug doxorubicin as well as molecules that recognize cancer cells.
The team tested the robots using mouse blood and artificial channels lined with human endothelial cells—the kind of cells that line the inner walls of our blood vessels. The robots were exposed to a mixture of cancerous and healthy tissue. The microrollers selectively attached to the cancer cells and were activated using UV light to release the doxorubicin.
By applying magnetic fields, the team was able to control the movement of the microrollers, both with and against the flow of blood. The microrollers can reach a speed of up to 600 micrometers per second. “If you come to a spot where you need to take the right path and if you miss it, then you could go back and go to the right one,” says Setti.
In future, the researchers want to use other methods to start the drug release, such as heat or near-infrared light. They also plan to try making microrollers out of materials that would break down in the body over a few weeks or months.
The team hopes to test the microrollers in animals soon. “The rollers need to carry enough cancer drugs, which is why we need to have them in large numbers,” says Setti. “But since we can locally take drugs to the right target, we don’t need huge dosages (剂量).”

2 . Green exercise is a term used to describe any type of physical exercise that takes place in a natural environment rather than in a health club or gym.
A slightly different approach to green exercise puts more stress on the fresh air, sunshine and involvement with the natural world, rather than the equipment or clothing used during the exercise.
Many consider green exercise helps to reconnect human beings with the natural world. The interaction with nature helps to lower people's blood pressure, refresh their mind, and actually improve their self-esteem.
Not everyone believes that the green exercise is more beneficial than working out in a health club or gym.
| A．A green gym uses as little equipment as possible |
| B．Spirits are also believed to be positively affected |
| C．Opinions on what truly green exercise means differ |
| D．Green exercise includes a range of activities exposed to nature |
| E．So riding a bicycle in the forest can be called a type of green exercise |
| F．It usually doesn't use fitness equipment that is normally found in a gym |
| G．Some point out that many health clubs are built to make full use of natural light |
3 . The Importance of Handwriting is Becoming Better Understood
As primary-school pupils and PhD hopefuls return for a new school year, many will study with reliance on computers to take notes and write papers.
The benefits of using a pen or pencil lie in how the motor and sensory memory of putting words on paper reinforces that material. The arrangement of squiggles (涂鸦) on a page feeds into visual memory.
One of the best-demonstrated advantages of writing by hand seems to be in superior note-taking.When primary-school pupils and PhD hopefuls take notes, handwriting forces students to synthesise (合成) ideas into their own words. This aids conceptual understanding at the moment of writing.
Many studies have confirmed handwriting’s benefits, and policymakers have taken note. Though America’s “Common Core” curriculum from 2010 does not require handwriting instruction past first grade (roughly age six), about half the states since then have required more teaching of it, thanks to campaigning by researchers and handwriting supporters.
| A．However, note-taking by hand takes longer time. |
| B．One solution to the complaints may be handwriting. |
| C．A line of research shows the benefits of computers replacing handwriting. |
| D．Some parents are disturbed that their children are playing games on laptops in class. |
| E．And those taking notes by hand also perform better on tests when they review notes. |
| F．In Sweden there is a push for more handwriting and printed books and fewer devices. |
| G．People might remember a word they wrote down in class as being at the bottom-left on a page. |
4 . Although most games have winners and losers, the goal of sports is not to win every game. The real goals include getting exercise, having fun, and learning important social skills, like sportsmanship.
Good sportsmanship is all about respect. Good sports (有体育精神的人) respect their teammates and also their opponents. They respect their coaches, and they also respect the referees or other officials involved in their games.
Kids usually learn sportsmanship good and bad from the adults in their lives.
Learning good sportsmanship is important because it helps you develop an attitude of graciousness (礼貌) and respect that will carry over into all the other areas of your life.
So be a good sport in whatever you do!
| A．Good sportsmanship can be shown in many ways. |
| B．However, bad sportsmanship is all about disrespect. |
| C．Players’ parents and coaches set examples that kids tend to follow. |
| D．We can be good sports by encouraging others but not laughing at them. |
| E．Starting as a good sport earlier will help you be a good sport as you get old. |
| F．If you’re a good sport on the field, you’ll also likely be a good sport in the classroom. |
| G．The example you set can be a powerful teaching tool for others. |
5 . Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle —named the Transition – has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.
Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t help if you’re stuck in traffic. The car needs a runway.
Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.
Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

6 . Harvesting fruits is a very demanding job. If pickers are not available, fruits will rot on the trees. But with pickers in short supply in recent years, growers needed to quickly find another way to harvest their fruits.
An Israeli company Tevel has developed these flying autonomous robots. The robots fly over a tree and pick fruits with its arms. They are fitted with cameras that use AI to assess the size and color of the fruit.
Dozens of these smart robots can be used across an orchard (果园) during the time when the fruit is ready to be harvested. The farmers just need to tell the company how many flying robots they need and how long they will use.
The robots arc now picking pears in Israel. The company also plans to add more tasks to the robot’s function.
| A．So only the ripe ones are collected. |
| B．Now a new type of robot can come to their help. |
| C．Finding fruit pickers is farmers’ biggest concern. |
| D．They can receive timely information from the robots. |
| E．Another advantage of the robots is that they never feel tired. |
| F．Then the company will transport the robots to their orchards. |
| G．For example, they can be used to cut off branches and water fruits. |
7 . It was a sunny afternoon in June of 2022 when 20-year-old Anthony Perry stepped off the train at Chicago’s 69th Street station. On the platform, two men were fighting bitterly. Then the unthinkable happened: the pair fell over the edge and onto the tracks. One man ended up on his back. Suddenly, he started convulsing (抽搐) unnaturally. He had fallen on the third rail, the conduit (导线管) for the 600 volts of electricity that powers Chicago’s L trains. The aggressor leaped backward, bounded back up onto the platform and disappeared.
Perry couldn’t just stand there and watch. He sat at the edge of the platform and eased himself down. He took a few quick bounds and approached the victim. The guy looked dead, his body still moving violently as the electricity pulsed (搏动). Gathering up his courage, Perry reached down and grasped the victim’s wrist. Instantly, he felt a blast of electric shock shoot through his body. Perry shrank and jumped back. He reached down a second time, and was shocked again. But the third time he seized the man’s wrist and forearm and, braving the shock, pulled with all his strength. The guy’s body slid briefly along the third rail, coming to rest on the gravel on the outer edge of the tracks.
The man was breathing, but irregularly. Something wasn’t right. “Give him chest compressions (按压)!” yelled a woman. Perry was no expert, but for a few moments he worked on the man’s heart until the victim began convulsing. Then he heard a sudden noise behind him — medical workers and firefighters had arrived. Perry let the professionals take over. His heart still racing from the electric shocks, he climbed back up onto the platform, grabbed his things and headed home.
The evening news reported the incident. After a friend outed him to the media, Perry became the toast of Chicago. Perry was then recruited by the Chicago Fire Department and is now training to be an emergency medical technician.

8 . In 1812, the year Charles Dickens was born, there were 66 novels published in Britain. People had been writing novels for a century—most experts date the first novel to Robinson Crusoe in 1719—
but nobody wanted to do it professionally. The steam-powered printing press was still in its early stages; the literacy（识字） rate in England was under 50%. Many works of fiction appeared without the names of the authors, often with something like “By a lady.”Novels, for the most part, were looked upon as silly, immoral, or just plain bad.
In 1870, when Dickens died, the world mourned him as its first professional writer and publisher, famous and beloved, who had led an explosion in both the publication of novels and their readership and whose characters — from Oliver Twist to Tiny Tim— were held up as moral touchstones. Today Dickens’ greatness is unchallenged. Removing him from the pantheon（名人堂） of English literature would make about as much sense as the Louvre selling off the Mona Lisa.
How did Dickens get to the top? For all the feelings readers attach to stories, literature is a numbers game, and the test of time is extremely difficult to pass. Some 60,000 novels were published during the Victorian age, from 1837 to1901; today a casual reader might be able to name a half-dozen of them. It’s partly true that Dickens’ style of writing attracted audiences
from all walks of life. It’s partly that his writings rode a wave of social, political and scientific progress. But it’s also that he rewrote the culture of literature and put himself at the center. No one will ever know what mix of talent, ambition, energy and luck made Dickens such a singular writer. But as the 200th anniversary of his birth approaches, it is possible — and important for our own culture—to understand how he made himself a lasting one.

9 . Do you still remember the scene in the famous movie Titanic, directed by Cameron, where Jack was frozen to death in the icy cold water so that Rose could survive on the floating door alone? It broke many people’s hearts. Two decades later, people are still asking the question, “wasn’t there enough room on the door for both of them?” Cameron once responded by saying it wasn’t a question of room, but buoyancy（浮力）— if both of them had tried to stay on the door, he argued, the whole thing would sink.
But several guys from “Mythbusters”, an Australian-American science entertainment television program, decided to put the theory to the test themselves. They discovered that if Rose had took off her life jacket to the bottom of the door, there would have been enough buoyancy to keep both of them afloat.
“It was an artistic choice, the thing was just big enough to hold her, and not big enough to hold him,” Cameron said. “I think it’s all kind of silly, really, that we’re having this discussion 20 years later. But it does show that the film was effective in making Jack so attractive to the audience that it hurts them to see him die. The film is about death and separation; he had to die.”
Since Jack was doomed to die, Cameron said, it could have happened in a variety of different ways. It’s not about the door not being big enough: that’s just a practical method for his death. “Whether it was that, or whether a chimney（烟囱）fell on him, he was going down,” Cameron said. “It’s called art: things happen for artistic reasons, not for physics reasons.”
1. According to Cameron, why can’t audience accept Jack’s death?| A．They are artistic people. | B．They like the movie. |
| C．They love Jack. | D．They are eager for truth. |
| A．Jack died by accident. | B．Jack’s death was unavoidable. |
| C．The chimney fell on Jack. | D．The door could make a difference. |
| A．Jack Had to Die | B．A Door of Life and Death |
| C．Audience Knew Better | D．Science Behind Movie |
| A．A popular magazine. | B．A movie poster. |
| C．A government report. | D．A notice board. |
10 . HANDSTITCHED WORLDS: THE CARTOGRAPHY OF QUILTS
Quilts (床罩) are a narrative art; with themes that are political, spiritual, communal, or commemorative, they are infused with history and memory, mapping out intimate stories and legacies through a handcrafted language of design. Handstitched Worlds: The Cartography of Quilts is an invitation to read quilts as maps, tracing the paths of individual histories that illuminate larger historic events and cultural trends.
Spanning the nineteenth to twenty-first centuries, this insightful and engaging exhibition brings together 18 quilts from the collection of the American Folk Art Museum, New York, representing a range of materials, motifs, and techniques from traditional early-American quilts to more contemporary sculptural assemblages. The quilts in Handstitched Worlds show us how this too-often overlooked medium balances creativity with tradition, individuality with collective zeitgeist. Like a road map, these unique works offer a path to a deeper understanding of the American cultural fabric.
