3 . For years, David James, who studies insects at Washington State University, had wanted to examine the migration (迁徙)patterns of West Coast monarch butterflies (黑脉金斑蝶). The route the butterflies travel has been hardly known because the populations are too small to follow. For every 200 monarchs tagged (打标签)by a researcher, only one is usually recovered at the end of its trip, James says, and finding even 200 in the wild to tag is unlikely. Knowing the route is vital to conservation efforts, but James had no way to figure it out- until he got a phone call from Washington State Penitentiary in Walla Walla.

The prison was looking for new activities to improve the mental health of those serving long-term sentences. So James began working with prisoners to raise monarchs through the whole process of their transformation. The adult insects were then tagged and released from the prison. Over five years, nearly 10, 000 monarchs flew from the facility. Elsewhere in Washington, Oregon and Idaho, researchers released another few thousand.

The tags included email addresses, and soon after the first butterflies took off, James started receiving messages from people who had spotted them. The butterflies, the reports confirmed, wintered in coastal California. Twelve of them landed at Lighthouse Field State Beach in Santa Cruz. Several more headed to Bolinas and Morro Bay.

The work helps researchers identify ideal places to plant milkweed and other vegetation that are important to the life cycle of West Coast monarch butterflies. It also brought out the gentler side of some of the prisoners. “They were very worried that they were going to harm the butterflies, ”James says. Watching the monarch change their form also touched the men. “This butterfly changed, ” James recalls prisoners telling him, “and maybe we can too. ”

4 . My mother is 92. Unless I have to be out of town, each week I take my mother to do her _______ and visit the doctor, providing _______ and transportation. During the week, however, she likes to go to a nearby store to _______ some small things she needs.

Last week she walked up to the store, but when she went to pay for her groceries, she was _______ about three dollars. The only _______ to pay for the groceries was to take off the _______ she could do without: a bottle of rubbing alcohol (医用酒精) and a bar of soap. By taking off these, she was able to _______ the new total to the amount of cash she had with her.

At this store, people _______ and then go off to the side to _______ their own groceries. My mother was putting her groceries into shopping bags when a ________ came up to her and said, “Here are the things that you ________ .” handing her the rubbing alcohol and the ________ . My mother, who is never speechless, was speechless. She ________ for the woman’s name and address so that she could ________ her. The woman told her it was her ________ .

My mother was so ________ by her gesture that she decided to go back to the store and give the cashier (收银员) a five-dollar bill to keep on hand ________ the same happened to someone else if they didn’t have enough ________ for all of their groceries.

So, whoever you are, thank you for the random act of ________ that not only helped my mother out, but ________ too.

5 . Quantum ( 量子 ) computers have been on my mind a lot lately. A friend has been sending me articles on how quantum computers might help solve some of the biggest challenges we face as humans. I’ve also had exchanges with two quantum-computing experts. One is computer scientist Chris Johnson who I see as someone who helps keep the field honest. The other is physicist Philip Taylor.

For decades, quantum computing has been little more than a laboratory curiosity. Now, big tech companies have invested in quantum computing, as have many smaller ones. According to Business Weekly, quantum machines could help us “cure cancer, and even take steps to turn climate change in the opposite direction.” This is the sort of hype ( 炒作 ) that annoys Johnson. He worries that researchers are making promises they can’t keep. “What’s new,” Johnson wrote, “is that millions of dollars are now potentially available to quantum computing researchers.”

As quantum computing attracts more attention and funding, researchers may mislead investors, journalists, the public and, worst of all, themselves about their work’s potential. If researchers can’t keep their promises, excitement might give way to doubt, disappointment and anger, Johnson warns. Lots of other technologies have gone through stages of excitement. But something about quantum computing makes it especially prone to hype, Johnson suggests, perhaps because “‘quantum’ stands for something cool you shouldn’t be able to understand.” And that brings me back to Taylor, who suggested that I read his book Q for Quantum.

After I read the book, Taylor patiently answered my questions about it. He also answered my questions about PyQuantum, the firm he co-founded in 2016. Taylor shares Johnson’s concerns about hype, but he says those concerns do not apply to PyQuantum.

The company, he says, is closer than any other firm “by a very large margin ( 幅度 )” to building a “useful” quantum computer, one that “solves an impactful problem that we would not have been able to solve otherwise.” He adds, “People will naturally discount my opinions, but I have spent a lot of time quantitatively comparing what we are doing with others.”

Could PyQuantum really be leading all the competition “by a wide margin”, as Taylor claims? I don’t know. I’m certainly not going to advise my friend or anyone else to invest in quantum computers. But I trust Taylor, just as I trust Johnson.

8 . My name is Alice. Early last year, I was troubled by an anxiety that crippled ( 削弱 ) my ability to do anything. I felt like a storm cloud hung over me. For almost a year I struggled on, constantly staring at this wall that faced me. My perfectionist tendencies were the main root of this: I wanted to be perfect at whatever I did, which obviously in life is not possible, but it consumed me.

One day, I attended a presentation by wildlife conservationist Grant Brown at my high school. His presentation not only awed and inspired me, but also helped emerge an inner desire to make a difference in the world. I joined a pre-presentation dinner with him and that smaller setting allowed me to slowly build up my courage to speak one-on-one with him—an idea that had seemed completely impossible. This first contact was where my story began.

A month later, Brown invited me to attend the World Youth Wildlife Conference. Looking back, I now see that this would be the first in a series of timely opportunities that my old self would have let pass, but that this new and more confident Alice enthusiastically seized. Shortly after I received his invitation, applications to join the Youth for Nature and the Youth for Planet groups were sent around through my high school. I decided to commit to completing the applications, and soon I was a part of a growing global team of young people working to protect nature. Each of these new steps continued to grow my confidence.

I am writing this just six months since my journey began and I’ve realised that my biggest obstacle ( 障碍 ) this whole time was myself. It was that voice in the back of my head telling me that one phrase that has stopped so many people from reaching their potential: I can’t. They say good things come to those who wait; I say: grab every opportunity with everything you have and be impatient. After all, nature does not require our patience, but our action.

9 . Dr. Smith of New York works at a center for children who can’t learn well. One day a father brought his son to him for________ at his office.

The father told Dr. Smith about his son. “My son has ________ in learning and can’t even play baseball. He isn’t doing well because he doesn’t try. I have done everything for him. I have even shouted at him. But nothing ________. ”

After Dr. Smith tested the boy, he ________ his father. He asked the father to sit in front of a ________ and then gave him a pencil and a piece of paper. There was a ________ on the paper. He asked the father to look only in the mirror and ________ the lines of the star with the pencil. The father made the same ________ anyone makes. Every time he ________ the pencil, it went the wrong way. The father’s face became red.

At this ________ the doctor shouted at him, “Hurry up! Why are you ________ so long? You can’t do such an ________ thing! You don’t know left from right!” These ________ made the father very angry.

“Now you can ________, can’t you?” The doctor said to him. “Your son has felt just like that all the time. You scolded (训斥) him too often, so he didn't try any more. He was afraid of making mistakes. ”

________ the father understood everything. He put his face down. Now he felt so sorry.

10 . We all know that unpleasant feeling when we’re talking about something interesting and halfway through our sentence we’re interrupted. But was that really an interruption? The answer depends on whom you ask, according to new research led by Katherine Hilton from Stanford University.

Using a set of controlled audio clips (录音片段), Hilton surveyed 5, 000 American English speakers to better understand what affects people’s perceptions of interruptions. She had participants listen to audio clips and then answer questions about whether the speakers seemed to be friendly and engaged, listening to one another, or trying to interrupt.

Hilton found that American English speakers have different conversational styles. She identified two distinct groups: high and low intensity speakers. High intensity speakers are generally uncomfortable with moments of silence in conversation and consider talking at the same time a sign of engagement. Low intensity speakers find it rude to talk at the same time and prefer people speak one after another in conversation.

The differences in conversational styles became evident when participants listened to audio clips in which two people spoke at the same time but were agreeing with each other and stayed on topic, Hilton said. The high intensity group reported that conversations where people spoke at the same time when expressing agreement were not interruptive but engaged and friendlier than the conversations with moments of silence in between speaking turns. In contrast, the low intensity group perceived any amount of simultaneous (同时) chat as a rude interruption, regardless of what the speakers were saying.

“People care about being interrupted, and those small interruptions can have a massive effect on the overall communication,” Hilton said. “Breaking apart what an interruption means is essential if we want to understand how humans interact with each other.”
