1 . Passenger pigeons (旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.
It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by American’s need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.

2 . Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory,for education was for the rich then.So, the world became his school.With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown."There's so much to learn," he'd say.“Though we're born stupid, only the stupid remain that way.”He was determined that none of his children would be denied(拒绝)an education.
Thus, Papa insisted that we learn at least one new thing each day.And dinner time seemed perfect for sharing what we had learned.We would talk about the news of the day;no matter how insignificant, it was never taken lightly.Papa would listen carefully and was ready with some comment,always to the point.
Then came the moment-the time to share the day's new learning.
Papa, at the head of the table, would push back his chair and pour a glass of red wine,ready to listen.
Felice, “he'd say,”tell me what you learned today.“learned that the population of Nepal is...”
Silence.
Papa was thinking about what was said, as if the salvation(拯救)of the world would depend upon it.“The population of Nepal.Hmm.Well...”he'd say.“Get the map; let's see where Nepal is.” And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn.Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children, we thought very.little about these educational wonders.Our family,however,was growing together,sharing experiences and participating in one another’s education And by looking at us,listening to us, respecting our input, affirming(肯定)our value; giving us a sense of dignity, Papa -was unquestionably our most influential teacher.
Later during my training as a future teacher studied with some of the most famous educators.They were imparting(传授)what Papa had known all along-the value of continual learning.His technique has served me well all my life.Not a single day has been wasted, though I can never tell when knowing the population,of Nepal might prove useful.

3 . Do you think alien beings exist somewhere in the universe? It seems like Mars, our closest neighbor, has inspired the most science fiction as the place where aliens are most likely to come from. Recent Mars probes (探测) have shown us that there is no life on that planet—at least not now. But that does not mean that life does not exist elsewhere—after all, the universe is really big. A lot of scientific research is going on in the search for “extraterrestrial life”.
Think about it—why should the seven billion people on this little planet be the only living beings in the universe? It would, in fact, seem logical that this is not the case. So scientific research in this matter is based around the idea of finding other planets that have environments that can support life —environments similar to the Earth. The search is on for the evidence of the existence, or earlier existence of life: from very wise beings to simple organisms (有机物).
So far, there have been a number of theories as to which planetary bodies may have an atmosphere that can support such life and therefore deserve closer attention. As for places within our own Milky Way Galaxy, it has been assumed over the decades that Mars and Venus, as well as some of the moons of Jupiter and Saturn, may have been hosts for life. Now, as technologies have improved and we can obtain measurements of the composition of the atmosphere on extra-solar planets, the chances of finding “alien” life forms are increasing.
There has been a theory that some of the planets in the habitable zone of the red dwarf star Gliese 581 may be able to support life. In 2007, scientists discovered exoplanet Gliese 581c—and felt that its atmosphere was most suitable for supporting life. But further research revealed that it would not. Now, attention has been turned to Gliese 581d, at the outer edge of the star’s habitable zone. The main standards for deciding whether a planetary body can be life-supporting are atmospheric conditions which allow the existence of water. Gliese 581 is about 20. 4 light years away from the Earth, so even if life does exist there, the distance would mean that communication would be unlikely.
Having said this—who says alien life forms (if they exist) need water?
1. What does the underlined part in Paragraph 1 mean?| A．Life existing outside of the Earth. |
| B．The evidence of the existence of life. |
| C．Other faraway planets in the universe. |
| D．Creatures known from science fictions. |
| A．Modern scientific theories. | B．Atmospheric conditions. |
| C．Environments similar to the Earth. | D．Advanced technologies. |
| A．the atmosphere of Gliese 581c was most suitable for life |
| B．it is not certain whether alien life forms need water or not |
| C．the 7 billion people on the Earth are the only beings in the universe |
| D．the distance of 20. 4 light years makes it impossible to find life on Gliese 581d |
| A．Do Aliens Exist? | B．Is Mars Suitable for Life? |
| C．Are Alien Life Forms Various? | D．Can We Communicate with Aliens? |
4 . Growing up, we are constantly reminded that young people are heavily affected by technology. We are the “antisocial club”, those who prefer to text our friends in the same room rather than make eye contact with them. And even though never-ending studies reveal to us the extent of our social media addiction, we should at least consider that it’s not only our young people’s problem any more.
There’s the rise of the Instagram mums, who like to post an abundance of cute baby pictures, share their mom feelings along the way and show their wonderful lifestyles. They are the so-called “Facebook mum generation”, a growing group of parents that like to overshare.
While all of this might be fine, and even a little humorous, new research suggests that parents’ technology addiction is negatively affecting their children’s behavior. According to the study, 40% of mothers and 32% of fathers have admitted having some sort of phone addiction. This has led to a significant fall in verbal interactions within families and even a decline in mothers’ encouraging their children.
There is no denying that I get annoyed when receiving the words “I’ll be with you soon” from a parent, when all I want to do is ask one question. But, at the same time, every day leaving the room to wait until my father is finished with his “serious business” (Farmville), has now become the norm. Whether you want to escape your disturbing children for a bit, or want to stay up late flicking through Twitter, know that wanting to do all of these is normal. We, your children, know how addictive it can be and how difficult it is to switch off. But before telling us to put our phones away at the table or even worse, listing statistics of how damaging social media can be for us, maybe lead by example, considering how much time you spend on the phone and how this is impacting your children and your relationship with us. Maybe in this way we can work on our addiction together.

5 . For some years，my mother worked for a charity as President and Secretary.Selling raffle tickets(兑奖券) was her main means of bringing in the charity’s muchneeded funds.We girls would accompany her，selling tickets with great success.My father made and donated beautiful wooden toys，jewellery boxes and other lovely items as prizes.
Now my sister was always coming up with “good ideas”，most of which didn’t work out to plan.But that didn’t deter her.She had many just waiting to be tested.When she was eight and I was just five，we had a wonderful idea for a business adventure.We decided we would sell raffle tickets for charity，and that charity was us!
So one afternoon，we told our mother we were going to play in the park with our cousins as we did most days after school.But instead，we walked around the streets armed with a raffle book，a pen and a large cloth bag to carry the money.
We’d accompanied our mother many times when she sold tickets，so people were familiar with us when we appeared at their doors.Despite the blank looks they received when asking about the prizes on offer，they were very generous.Although there were no actual prizes，our mother’s previous track record enabled us to sell nearly the whole book of raffle tickets.
Like a little pair of lottery(彩票) winners，we walked home and proudly showed off our takings.But our enjoyment of this sudden wealth was shortlived，and our plans for spending it quickly failed.Our angry mother took us back to every ticket buyer，making us apologise and give the money back.Thankfully，our sweet neighbours didn’t make a big deal of our “clever” misbehavior and thus my mother’s
fundraising career could continue safely.We were taught a good lesson by our mother that day.Also I remember my sister’s entrepreneurial(企业家的) spirit dried up a bit after that.

6 . Surrounded by Brothers
I know it is wrong to envy your children. But when I see my son, Tonio and his young brother Sam going down a slide together, one’s arm around the other, I know I have missed something wonderful.
Not only did I never have a brother, but also I had no friendships like theirs. My sister was old enough to help take care of me, so she was more a mother than a playmate, and I was more a pest than a friend. A brother would have been wonderful, but it was not in the family planning.
Now I finally live with brothers, my sons, Tonio and Sam. I am watching them build the kind of relationship that I once dreamed about. They go to bed together. When one comes into our bed after a nightmare, my wife and I know that before morning his brother will follow.
Sam manages the world with more ease than his elder brother, whose frustrations often bring him to tears. With a sincere “Smile, Tonio,” Sam is the one who comforts him. Tonio, on the other hand, has stopped playing with boys at his age who don’t like playing with Sam. They are always backing each other up.
I don’t know what kind of relationship they will have when they grow up. Parents always want their children to have what they never could. I want them to have each other. So I imagine them going to the same college, marrying sisters and living on the same block.
That’s why I was so worried the day Tonio started kindergarten. I felt that I would lose something too. As we headed for school that morning, both boys seemed relaxed, as if neither had any idea that the day was going to be different, that starting then, Tonio would be leaving behind his brother, his best friend, his right arm.
Tonio’s first day was chaotic, with hundreds of children outside looking for their teachers. Before any of us could say goodbye, Tonio disappeared with his new classmates. He turned to wave and then was gone. It was so sudden. Sam even didn’t see him go. Although parents had been asked to ease the craziness of the first day by staying out of the school, I lifted Sam up and took him to Tonio’s classroom, looking for a glimpse of Tonio. Sam spotted him first.
My wife and I didn’t head back home immediately, stopping instead at a coffee shop to treat Sam to hot chocolate. We even let him eat ice-cream with his fingers. Sam was still quiet, so I asked him if he missed his brother already.
He didn’t answer. Instead he asked, “Daddy, is Tonio going to be gone forever?”
“No, Sammy,” I said, feeling happy about his sweet question. “Not forever, just until three o'clock.”
I sometimes think that the greatest thing I have ever done is to help create these brothers. And I didn’t stop with them. We had another child, and for the third time in a row, it was a boy. It wasn’t long before his brothers climbed into the crib to play with him. I am surrounded by brothers.

7 . Bradley McConachie, a 33-year-old Australian is actually a student in international relations completing his PhD through Griffith University. He came to Beijing for a cooperative research at Beijing University two years ago. Such an academic life was colorful with a chance offered by the cultural exchanges project, “I'm in China".
Bradley was lucky to win the most "likes" for his photo story about his life in China and became one of 20 winners to visit locations by the project this summer. All the winners’ experiences were filmed to produce a reality show, My Chinese Working Day, which will be broadcast by mid-September.
Bradley was chosen to work as a recreational manager for a Chinese wedding. The film crew took them to many “amazing sites" and the staff at the resort taught them a lot about how to incorporate modern Chinese features while still keeping traditional customs.
“I would have to say two things stick out as the most memorable： the helicopter ride and talking with the staff at the hotel about how they organize weddings here in China," he said. That was Bradley's first time to be in a helicopter, and he was too absorbed with the “stunning" view of the coastline.
“I think it is so important to show other Australians the different landscapes China has to offer. I think so many Australians, when they think about China, imagine the historical sites of Beijing and the exciting things to see in Shanghai but have no idea about other beautiful places, like Sanya or the many other places people have been taken to in this TV series. It was nice to experience these little touches. I was happy to be a part of that experience!” Bradley said.

8 . At every turn in the Netherlands, the future of sustainable(可持续的) agriculture is taking shape—not in the meeting rooms of big companies but on thousands of modest family farms.
You can see it vividly on the farm run by Ted Duijvestijn and his brothers. At the Duijvestjns' 36-acre greenhouse near the old city of Delf, visitors wander among the deep green tomato plants, 20 feet tall. Rooted not in soil but in materials made from leaves and stalks, the plants are heavy with tomatoes—15 varieties in all—to suit the taste of the most demanding customers.
Since 2004, the Duijvestijns have declared resource independence on every front. The farm produces all of its own energy and fertilizer and even some of the packaging materials necessary for the crop's distribution and sale. The growing environment is kept at perfect temperatures year-round by geothermal heat(地热) that can be found under at least half of the Netherlands. Only rainwater is used for irrigation. Each kilogram of tomatoes from their plants requires less than 15 kilograms of water, compared with 61 kilograms for plants in open fields. Once each year the entire crop is regrown from seeds, and the old plants are processed to make packaging materials. The few pests that manage to enter the greenhouse are greeted by an army of fierce insects that shows no interest in tomatoes. The nutrition in the soil can be improved by growing plants that work with certain bacteria to produce their own fertilizer. In short. it's an entirely self-contained food system.
“Look at the island of Bali in Indonesia!” Ted explains. “For at least a thousand years, its farmers have raised ducks and fish within the same rice field. It's irrigated by the canal systems sculpted by human hands along mountains. They are our model.”

9 . With races delayed and outdoor exercise limited, COVID-19 has put the brakes on China’s previously booming marathon industry as event organizers struggle to make ends meet during the crisis. The sparse turnout（到场人数）of runners at Beijing’s Olympic Forest Park these days bears witness to the decline.
Despite the successful containment of the outbreak in China, fears over the potential risks of mass gatherings clearly remain within the running community, while the virus-enforced business shutdown has created a severe challenge to organizers and promoters involved in the sport. Event organizers are struggling to survive through the crisis with the majority of their source of income dried up.
Last Thursday’s cancellation of the 2020 Chengdu Panda Marathon showed that local governing bodies and organizers remain cautious against the virus despite a growing urge among the running community to get back to normality. With this year’s emptied spring schedule, industry experts expect that businesses face a daunting（令人生畏的）second half of the year even if races are allowed to restart.
“Due to the delay of events originally scheduled in the first half, the number of races will skyrocket in the second half if the government gives the green light,” said Chen Guoqiang, a sports sociology researcher at Shanghai University of Sport. “Event organizers will have to compete harder against each other to attract enough runners, sponsors and media exposure to make their races profitable.”
Bao Mingxiao, director of the China Sports Economic Research Center, suggests that race organizers and promoters should focus on improving race quality by providing more professional services and better online interactions with participants whenever events restart. “The rising public awareness of having a healthy lifestyle will only be strengthened after the coronavirus(冠状病毒) crisis,” Bao said during an online forum(论坛) earlier last month. “For the long term, the sport participation and consumption will be very likely to bounce back.”

10 . "Smile!" I shouted, holding a yellow sign up on a busy street in Seattle. We were three thousand miles away from home on a Random Acts of Kindness and Volunteerism Road Trip. We had two aims. One was to try out our new "Smile!" signs and see how much kindness and joy we could spread in Pike Place Market. The other was to raise $80 by doing street performances, enough for gas to Portland and a small hotel room.
We weren't sure how people would react (回应) to our signs. I nervously raised up our signs and shouted, "Hi, there!" to a young couple. They looked over and felt confused. Then they read our signs and broke into a smile. Before long, some tourists wanted to take a photo with us and some strangers stopped to ask us about our signs.
In fact, we paid so close attention to our "Smile!" project that we forgot the other aim. Before we knew it, the sun was setting, and we had no money for our trip to Portland. We sat down to watch a blind musician play the guitar while thinking about what to do. He was packing up when a passing crowd kicked down his change bowl. He stumbled (绊倒) into the crowd. We rushed to help him, but another man moved more quickly to help him.
Once the musician had his money safely returned, we ran over to meet the strange helper and said, "We just wanted to praise you for your good deed." He smiled, looking at our signs. "Your trip reminds me of something similar I once did when I was young," he said. "Look! I'd like to donate (捐赠)." We told him, "No, thanks! We are fine. We've collected plenty of money." We lied. "Please let me donate. It will make me feel like I'm a part of this adventure," he insisted. And then the stranger opened his wallet and pulled out four $20 bills. The money was exactly what we had intended to raise that day. We were astonished. It seemed as if he had known somehow.
