2 . For people who are planning a trip, a visit to a museum might not be the first thing they think of. After all, there are plenty of ways to appreciate the world’s civilization, gain exciting experiences and spend quality time with family and friends.     1    

Museums are where people learn something new, at every age! Are you interested in something specific?     2    . There, you will find yourself drawn in and inspired! Museums are a fantastic place to learn about a region’s history, scientific achievements, major cultural events, and of course, dinosaurs. They also design exhibitions related to visual arts, industrial innovations and anything that inspires an individual to learn about the past and create new paths to the future.

    3     They will surely be an exciting part of the educational experience with the main purpose to expose children to knowledge of various fields and expand their horizons. To achieve that, museums are working to create meaningful and engaging activities, interactive and knowledge-based.

Museums support tourism. They are tourism promoters in small towns and large cities. Museums aren’t a burden on tax revenue (税收) or a separate concern from other city projects.     4    Statistics show that museums support more than 726, 000 jobs in America.

Museums shape communities. They have activities and exhibitions through which visitors can learn about local history. Museums are places where a shared heritage is celebrated and a collective identity is formed. They provide an interesting public space where people meet and talk to each other.     5    

3 . 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.

4 . 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.

5 . We live in a town with three beaches. There are two parts less than 10 minutes’ walk from home where neighborhood children gather to play. However, what my children want to do after school is pick up a screen — any screen — and stare at it for hours. They are not alone. Today’s children spend an average of four and a half hours a day looking at screens, split between watching television and using the Internet.

In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend. A couple of years ago film-maker David Bond realised that his children, then aged five and three, were attached to screens to the point where he was able to say “chocolate” into his three-year-old son’s ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself “marketing director from Nature”. He documented his journey as he set about treating nature as a brand to be marketed to young people. The result was Project Wild Thing, a film which charts the birth of the World Network, a group of organisations with the common goal of getting children out into nature.

“Just five more minutes outdoors can make a difference,” David Bond says. “There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven, then being outdoors will be on habit for life.” His own children have got into the habit of playing outside now: “We just send them out into the garden and tell them not to come back in for a while.”

Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it. Let us get them out and let them play.

7 . While taking a 20-hour train ride along the edge of the Taklimakan Desert in northwestern China, I had the kind of humbling, educational, and above all else, wonderful ________ with a local that all travelers long for. A young Chinese man ________ me on the train. My ________ friend spoke virtually no English, so I happily took the ________ to practice my Chinese.

Over several hours, he would tell me about how he had ________ a two-year professional school to quickly find a job ________ highways in order to help support his family. Perhaps the most ________, however, was the fact that this man spent hours studying every day after hard physical labor. Without batting an eye, he would ________ a translated Emerson passage before asking about the literary influence of American ________ as a whole. ”And what do you all learn about Russian authors?” I ________ him asking at one point.

It would have been easy to ________ my assumptions about this highway builder who had never been more than a few hundred miles from home. But this highly informed, ________ , and admirable person prevented me doing so. In the course of a couple of hours, he ________ me just how much one can gain from ________ with an open mind, and a willingness to ________ with locals from all walks of life.

8 . 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.”
