1 . There has been a very serious decline in the numbers of shallow-water fish as a result of overfishing. People still want to eat fish, so the fishing industry must look at other sources, especially the deep waters of the Atlantic.     1    

Conservation measures will have to be put in place if these deep-sea fish are to survive. Research on five such species shows that numbers have declined by between 87 percent and 98 percent.     2     Many species could well disappear completely if the present trend continues. These are species that have been swimming in our oceans for hundreds of millions of years.

The problem is emphasized by the fact that the decline in numbers happened in less than twenty years. Deep-sea fish take a long time to reproduce and normally live for many years.     3     The average size of such fish also declined, with one species showing a 57 percent decline in average size. This is of particular concern, as large fish tend to produce more offspring than small ones.

    4     The deep-sea species have been caught as if they were the fast-breeding (快速繁殖) fish like sardine and herring. It is like killing elephants as if they reproduced at the same rate as rabbits.

The damage done by overfishing goes beyond the sea environment. Millions of people make a living in the fishing industry.     5     Measures must be taken to not only conserve ecosystems, but also sustain livelihoods and ensure food security.

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    

4 . 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 . 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.

9 . 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.

10 . 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.
