1 . A new drug-delivery system could replace needles with puffs (股) of air. Gassensmith studies bioengineering at the University of Texas. His team’s new tech goes beyond patient comfort, though. The device quickly delivers drugs without touching the bloodstream. And that could reduce the risk of spreading disease. He tested it out on his own arm. “I could feel it, but it wasn’t painful,” he reports.
The technology works by blowing in a puff of air through the skin. That gas carries a powder made of tiny bits of vaccine (疫苗) wrapped in metallic crystals (晶体). The crystal coating is really strong, Gassensmith says. As a result, the vaccine powder does not have to be refrigerated while stored. The air contains carbon dioxide, or CO2. Once in the body, the CO2 that carries the powder will mix with water. It creates a weak acid that breaks down the crystal cover. Released, the vaccine bits are then able to enter the bloodstream.
This gas-based drug-delivery system is an upgrade over previous ones. For instance, adjusting the gas that carries the vaccine powder can customize how fast the tiny crystal capsules release the drug. Testing showed that the drug released fastest when delivered with carbon dioxide. Plain air led to a slower, gentler release. Vaccines work best when released slowly. That allows them longer contact with the immune(免疫) system. But the team hopes the device could work for other medicines too. And some medicines must be released quickly. One such example is insulin, a crucial drug for many people with diabetes.
Fear of needles keeps many people from getting vaccinations. Gassensmith is optimistic that this new system might get around that. Future research must ensure that gas-delivered vaccines build immunity to disease as expected, said Weniger, a doctor, who studied vaccine technology for 30 years for the U. S. Centers for Disease Control and Prevention.

2 . When you try a new restaurant or book a hotel, do you consider the online reviews? Do you submit online reviews yourself? Do you pay attention if they are filtered (过滤)? Does that impact your own online review submissions?
In 2010, Yelp shared a video to help users understand how its review filter works and why it was necessary. In recently published research, T. Ravichandran, Ph. D. from Rensselaer Polytechnic Institute, and his team compared reviews of over 1,000 restaurants on Yelp to those same restaurants on TripAdvisor, which did not openly share its review filter policies. They found that the number of reviews submitted to Yelp decreased. Those submissions were increasingly negative and shorter in length compared to TripAdvisor. Also, the more positive a review, the shorter it was.
“Platforms are pressured to have content guidelines and take measures to prevent fraud (欺诈) and ensure that reviews are reliable and helpful,” said Ravichandran. Platforms use advanced software to flag and filter reviews. Once a review is flagged, it is filtered out and not displayed, and it is not factored into the overall rating for a business. “However, most platforms do not openly disclose their policies, leading consumers to suspect that reviews are controlled to increase profit by filtering so-called dishonest content,” Ravichandran added.
Whether or not to disclose review filters is a critical decision for platforms with many considerations. Users may put less time and effort into their reviews if they suspect that they have a significant chance of being filtered, or they may do the opposite to make their reviews less likely to be filtered. Since most false reviews are overly positive, users may assume that positive reviews are most likely to be filtered and act accordingly.
“Review moderation(审核) openness comes at a cost,”said Ravichandran. “Although openness helps to position a platform as fair toward advertisers, the resultant decrease in the number of reviews submitted impacts the platform’s usefulness to consumers.” Online reviews pose great opportunity for firms, but also raise complex questions. Platforms must earn the trust of users without sacrificing engagement.

Javon was the shortest kid in the class. It had been that way since the third grade. He’d had to ask to get his gym locker changed so that he didn’t have to struggle so much to reach it. For most kids, being short would be a problem, but Javon didn’t let being short bother him at all.
That was Javon’s attitude about most things except school work. And Javon had worked hard. By the middle of seventh grade, Javon was one of the top kids in the class. So, he hadn’t been too concerned when Mr. T announced they were starting a new unit in math. For Javon, math used to be easy. He figured that since he had ten fingers, he could do most of it. But when Mr. T threw letters into math problems, he couldn’t wrap his mind around using these letters. Mr. T had given them all sorts of rules for what to do when there were letters in math problems. But Javon couldn’t remember what they all were and he didn’t think he even understood the rules he did remember. Soon he was hopelessly lost in math class. Even worse, it was time for the class to take the chapter test.
The test was quite demanding. Javon was confused by the very first question. He was nervous and kept losing track of what he was doing. When the class period ended, he hadn’t finished all of the problems.
The day came when the class finally got their papers back. Seeing “D” written in red ink on the corner of the paper, he felt desperate. In the seat next to him, Tyler sighed slightly, catching Javon’s attention. He couldn’t help but see the big, red “C” on Tyler’s paper. He felt so upset.
When they started packing up to leave after class, Tyler accidentally told Javon he got extra time on the test. Upon hearing this, Javon burst out, “It was unfair!” He dropped his books, face hot.

_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________My story started one autumn morning, at the bend on a path.
I was 13 years old, and was on the way to school. It was the first time I had caught sight of a fox. Fascinated to the point that I forgot all fear, I dared to go up to it. I had never come so close to a wild animal. There was nobody else around, only me and the fox.
“Hey, fox!” I tried to greet it, though my voice was so weak that it felt like I was saying hello to myself. It didn’t hear me. It stayed there and I watched it. My heart was beating flat out. It was so cute. For a moment, I thought I might be able to touch it.
Throughout the day at school, I could only think of the fox at the big beech (山毛榉) tree. At my return to the place where we met, I was sure I’d find it there.
And I did. This time I gathered a little bit more courage and called out to it, “Fox!” Of course it escaped. But that only made me long to meet it again. I decided that if I could find its kennel (洞) and catch it, I would try and tame (驯服) it, making it my friend.
Thus, I spent most of my free time in the forests trying to find the fox during the following months. But I never saw it again before winter came. During the winter, I followed its footprints far across the fields. Suddenly I was alarmed by the howling of wolves near me. I ran away frightened, stumbled and hurt my ankle. It healed very slowly, so that I had to stay at home during the winter, reading a book about animals of the forest and foxes.
When spring arrived, I was free again. I looked for fox kennels and waited for my fox. To my amazement, it had got young ones but kept moving because of my observations; therefore I decided to observe the fox from a longer distance.

When I first met Nao Junior, he was in his 40s and one of only nine members of his Indigenous(土著的) group, Great Andamanese, who still spoke the idiom of his ancestors. As a language specialist, I had researched more than 80 Indian languages. I was on the islands to document their Indigenous voices before they faded into whispers.
Words in this language consisted of two classes: free and bound. The free words were all nouns that referred to the environment and its inhabitants, such as ra for “pig”. They could occur alone. The bound words were nouns, verbs, adjectives and adverbs that always existed with markers indicating a relation to other objects, events or states. The markers came from seven zones of the body and were attached to a root word to describe concepts such as “inside”, “outside”, “upper” and “lower”. For example, the morpheme(词素) er-, which qualified most anything having to do with an outer body part, could be stuck to -cho to yield ercho, meaning “head”.
Just as a head, a bound word, could not conceptually exist on its own, the mode and effect of an action could not be divided from the verb describing the action. Great Andamanese had no words for agriculture but a great many for hunting and fishing, mainly with a bow and arrow. Thus, the root word shile, meaning “to aim”, had several versions: utshile, to aim from above; arashile, to aim from a distance; and eshile, aiming to make a hole with a sharp object.
The studies established that the language seems to be truly old in origin. In a multistage process of development, words describing diverse body parts had changed into morphemes referring to different zones and combined with content words to yield meaning. The structure alone provides an insight into an ancient worldview in which the macrocosm(宏观世界) reflects the microcosm, and everything that is or that happens inseparably connects to everything else.

I still remember the winter of 1933 for a gift which made three girls happy.
Life was hard then, with lots of folks finding themselves penniless. When my shoes got holes, my dad just cut a piece of cardboard to slip inside them.
Maxine, my best friend, and I were in the choir. Then the principal, Mr. Robert announced a gift exchange among all the students. We each pulled a slip of paper with a name on it from a box. “Now don’t tell anyone whose name you got,” Mr. Robert reminded us. “This will be such a surprise!”
Of course, telling us to keep the names we’d picked secret was like asking a dog to stop barking. We figured out every single name. Maxine picked Peter and Barbara’s name was on my slip of paper. When we figured out who had my name, I almost fainted. It was Betsy! Betsy was poorer than the rest of us. My eager little heart sank. I knew I wouldn’t get anything from her.
Maxine and I were walking home that afternoon after choir practice. “What am I goanna do, Maxine, when my name is called? Stand up there looking stupid while everyone is watching me?” Maxine tried her best to make me feel better.
When we reached Maxine’s house, her mother called to us to see what Maxine’s aunt had sent her. A pair of red gloves was out on the table. “Oh,” Maxine cried with delight. “Look at the white snow angels on each of them!” She pulled off her worn brown gloves and slipped her hands into the new ones. “I have never seen anything so beautiful in my whole life,” I sighed. Well, I was happy for Maxine, but the sight of the gloves made me feel even sorrier for myself.
Finally the day for the gift exchange arrived. One name was called and then another. Kids jumped up, laughing happily and calling out to friends as they received their gifts. “Betsy,” Mr Robert called. I saw Betsy stand up hesitantly. Then Maxine stood up!
I caught Maxine’s arm. “You have Peter,” I reminded her. “I traded him,” she whispered as she walked over and handed her gift to Betsy. Betsy carefully unfolded her gift. My eyes popped out, and I think I even said, “Oh no!” out loud.

9 . One summer night, a boy felt himself lifted from bed by his father. Dazed with sleep, he saw stars flashing across the heavens. “What is it?” the child whispered. “Shooting stars. They come every year in August.” Decades have passed, but I remember that night still, because I was the fortunate boy whose father believed a new experience was more important than an unbroken night’s sleep.
Some parents like my father have the gift of opening doors for their children. This art of adding dimensions to a child brings the reward: the marvelous moment when the spark bursts into a flame that will burn brightly on its own one day. At a Golf Association tournament, a ten-year-old girl played creditably. “How long have you been interested in golf?” someone asked. “I got it for my ninth birthday,” she said.“ Your father gave you a set of clubs?” “No,” she said, “he gave me golf.”
I have a friend, a psychiatrist, who says there are two types of people: those who think of life as a privilege and those who think of it as a problem. The first type is enthusiastic and energetic. The other type is suspicious and self-centered. And he adds, “Tell me about your childhood and I can tell you which type you are likely to be.”
The real purpose, then, of trying to open doors for children is to build eager and outgoing attitudes, which is the most valuable legacy we can pass on to the next generation. But why don’t we work harder at it? Probably because sometimes we don’t have the awareness or the selflessness or the energy. And yet, for those of us who care what becomes of our children, the challenge is always there but the opportunities also come repeatedly. Many years have passed since that night. And next year, when August comes with its shooting stars, my son will be seven.

10 . Feel exhausted after a party? Rather see one close friend than a group of acquaintances? Enjoy your own company? In our world, that makes you an introvert (内向的人). However, there’s another possible explanation — vertical attachment. If you are closer to your parents and family members than to your peers, you are vertically attached, which means you rely more on family for comfort.
If you are closer to your peers, then you are peer attached. We live in a peer-oriented world. We believe that having lots of friends means that we are well-adjusted. We put our kids in playgroups and daycare for peer interaction. We expect teenagers to want to hang out with their friends, thinking it is the natural way of things.
Result? Generations often feel worlds apart. We use different language, dress, and technology apps. Even if multiple generations are invited to the same party, the kids go to the basement playroom while the parents stay upstairs.
Vertically-attached individuals can feel out of place in this context, demonstrating the traces of introversion. Will they be exhausted after a party with same-aged acquaintances? Absolutely. Would they rather spend time with one close friend? Sure. Do they enjoy alone time? Yes, more than they enjoy time fitting in with peers.
It’s normal that many people need alone time to recharge. However, vertically-attached people often label themselves as introverted. They feel insecure that others have more friends and live richer lives. They claim that their family attachments arise from their loved ones being stuck with them.
If you feel these insecurities, know that there is nothing wrong with you, and you are not missing out on anything. Your attachment style is just different from the culture where you live. Have confidence in the strength of the relationships you have, whether it is with a mom who feels more like a best friend, or a grandmother with whom you can share anything. They are meaningful, enriching relationships, even if they look different from the cultural norm.
1. Who is vertically attached according to the text?| A．Mike, who feels at ease with his teachers. |
| B．Maggie, who enjoys film time alone at weekends. |
| C．Tom, who feels burnt out after a family get-together. |
| D．Lisa, who often turns to her dad when things are hard. |
| A．Younger generations should be self-disciplined. |
| B．Being sociable is a desired quality for their children. |
| C．Their children need more friends than they themselves do. |

| A．Be that as it may, just leave it as it is. |
| B．Never underestimate your inner power. |
| C．Hang out more with friends and adjust to it. |
| D．Treat others the way you want to be treated. |
