It was the love of my children that 27 pulled me out of my despair and helped me to begin to live again. 28 , I continued to ask God why my Mom had to die so young.Only years later I began to 29 clearly what Mom had done in those last four years of her life. 30 cancer was beating her body, it certainly wasn’t beating her soul. Mom lived as she had 31 lived before. Even with cancer she worked outside our home and 32 the lives of her co-workers with her gentle, humor and kind spirit. She reconnected with old friends she hadn’t seen in years and made 33 memories with each one of them. She and my Dad 34 closer than I had ever seen them before. There was a 35 and a tenderness between them that moved us all. During her time with us she 36 our souls with her love and she helped us to grow 37 enough to go on without her.In her last four years Mom 38 her mission here. She showed us how to love God. She showed us how to meet death. She showed us that fear always flees in the face of 39 .

When I arrived to collect, I found the building was dark except for a single light in a ground floor window.I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.She kept thanking me for my kindne ss. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”“It’s not the shortest way,” I answered quickly.“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”I quietly reached over and shut off the meter(计价器).For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl.Sometimes she’d ask me to slow down in fron t of a particular building and would sit staring into the darkness, saying nothing.At dawn, she suddenly said,” I’m tired. Let’s go now.”We drove in silence to the address she had given me.“How much do I owe you?” she asked.“Nothing.” I said.“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.Almost without thinking, I bent and gave her a hug. She held onto e tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”41. The old woman chose to ride through the city in order to ______.A. show she was familiar with the cityB. see some places for the last timeC. let the driver earn more moneyD. reach the destination on time42. The taxi driver did not charge the old woman because he ______.A. wanted to do her a favorB. shut off the meter by mistakeC. had received her payment in advanceD. was in a hurry to take other passengers43. What can we learn from the story?A. Giving is always a pleasure.B. People should respect each other.C. An act of kindness can bring people great joy.D. People should learn to appreciate others’ concern.BDomestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (矿井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.The domestication of horses has had great effects on societies. For example, horse were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new from of rapid transportation helped cultures spread around the world.44.

You are one of the people who keep the social temperature at such a comfortable setting. I don’t know anyone in the office who is better liked than you.You can perhaps help with this. The collection of contributions towards gifts for employees’ personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral(葬礼)remembrance, four birthday gifts, and three graduation gifts.It’s not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don’t know them outside the office, who wouldn’t eve n recognize their graduating children, their marrying daughters and sons, or their dead relatives.This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper i n today’s office setting.Thank you for understanding.48. The underlined word “contributions” probably means ________.A. moneyB. suggestionsC. reportsD. understanding49. Hamilton is expected to _______.A. show more kindness.B. discontinue the present practiceC. quit being the organizer for gift givingD. know more about co-workers’ families50. This is basically a letter of ________.A. apologyB. sympathyC. appreciationD. dissatisfactionDWhen it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate(照亮)me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:“Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.When I lived for a time in London, I had a friend, He was in despair(失望)and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared andthen we parted. We gave London to each other.For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:“Yes, I must tell….”We have never met.It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist(心理学家),who will only fill up the healing(愈合的)silence necessary to those darkest moments in which I would rather be my own best friend.51.

Now I just want to take it as my mood board, recording my life in another nation.It’s quite an expected and challenging chance for me to spend one year in the USA. I am a little bit dependent person and easy to miss hometown. Therefore, I need to learn how to be independent and control myself in a sense.The first challenge is cooking. I cannot cook before as we, most young people, are treated well at home and eat in canteens or restaurants, while we have to learn cooking for ourselves since it’s not easy to overcome for me to ea t fast food here every day. After the master and two-year PhD studies, I have grasped the skills for doing experiments, so I can cook not that badly via those “talents”. I felt so proud with my masterpieces.The second challenge is going outside. I live in a quite small city without subway, taxi or even public bus (except school catbus). It’s quite inconvenient to live here without a car. However, I have no driving experience in China though I got the license six years ago. I don’t want to spend such a long time to practice it. My friends are very friendly and they drive me to the supermarket and go hiking with me, which makes me a little bit upset or embarrassed as a “bubble” between she and her boyfriend. On the other side, the lack of taking public transportation experience made me so confused when I first went to NYC for a conference. Fortunately, I met several nice guys and they showed me the correct ways. I am looking forward to walking or transporting around on weekends.The third challenge is overco ming loneliness. It’s hard to say why I may feel lonely even though I have Chinese roommates. I still cherish the dream last night that I went back to China even though for experiment purpose...I will work harder to realize my goal and return without any pity.56.

Weak-mindedBA bullying(欺凌)incident at a primary school in County Armagh, Northern Ireland should not be brushed off as “a joke that went too far”; rather, facts should be dug out and action should be taken to prevent similar events from happening on campus again, according to experts.Dr. Lewis-Snyder, a psychologist specializing in children’s growth issues, said schools should be careful about taking bullying incidents as mere tricks.“Instead, they should work to find out the root cause of the incident in a timely manner, guide the children involved to face and handle the incident in a correct way and teach them to behave properly to avoid-similar situations,” she said.She made the comments after a mother in Armagh posted a description on Face-book on Thursday of how her 11-year-old son was bullied at school, a top school in that area.The mother wrote that her fifth-grade son was the target of bullies who threw a toilet wastepaper basket at him, striking him in the head. The boy was also fooled by his classmates, she said, bringing on acute stress disorder, a mental illness caused by severe anxiety.The mother also wrote that the school described the incident as “a joke that went too far” and that the parents of the boy who threw the basket believed their son was “just being naughty”.The article went viral, with many internet users recalling being bullied at school.Dr. Lewis-Snyder said that schools and parents must pay more attention to the ethical(道德的)development and mental health of children, rather than just looking at their academicperformance.The Department for Education, together with a group of other departments, released a series of guidelines last month offering advice on how to deal with the problem.On Saturday, the school involved released a statement on its social media account saying that it had talked to the parents on both sides and would make further efforts to achieve an outcome satisfactory to all parties.60.

Two months later, these watermelons will be sent to Xi’an, the starting point of the Silk Road.Every autumn, these so-called “migratory birds(候鸟)” - technicians from Kouzhai village i n southwestern China’s Guizhou province - fly to Laos to plant watermelons and return to China next spring to start their own farm work.Yang Canxi, former Kouzhai village Party chief who is also an agricultural technician, said the village was lifted out of poverty through its strength in agricultural technology.He said Kouzhai village was the first to promote small-sized watermelons in the country, and it introduced a new technology to grow watermelons from the newly generated vines after harvesting the old ones, thus doubling the sale to 13,000 yuan, ($2,190) per unit area.In 1997, an official from Laos came to Yang for agricultural training. Twenty professionals were sent to provide watermelon planting skills services there, he said.“At that time, much of the land in Laos was dry and bare except for that used to grow rice. The locals saw technicians plant watermelon and even gave them the nickname of Chinese watermelon princes”, he said.Each technician earned roughly 10,000 yuan in the first year, which was increased to 20,000 yuan a year later.“Villagers flew into my office, asking to go abroad too,” he said.The business was soon expanded to Laos where Yang Guangyue, 30, and some friends decided to begin their own business inThe local credit cooperative lent them 800,000 yuan to establish a 13-hectare watermelonbase in Laos, which was expected to gain roughly two million yuan a year.“Laotians were also hired to work in the watermelon fields and they learned planting skills from us,” he said.Yang Canxi said now half of the income of Kouzhai village comes from this way of working.64.

Living just a few blocks from the beach, Natalie can see the ocean and hear the waves from her house. “It's the ocean that makes Rockaway so special,” she says.On October 29, 2012, that ocean turned violent. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridges closed.When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless highrise buildi ngs.“My mom tells me that I can't control what happens to me,”Natalie says, “but I can always choose how I deal with it.”Natalie's choice was to help.She created a website page, matching survivors in need with donors who wanted to help. Natalie posted information about a boy named Patrick, who lost his baseball card collection when his house burned down. Within days, Patrick's collection was replaced.In the coming months, her website page helped lots of kids:Christopher, who received a new basketball; Charlie,who got a new keyboard. Natalie also worked with other organizations to bring muchneeded supplies to Rockaway. Her efforts made her a famous person .Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.Today, the scars(创痕)of destruction are still seen in Rockaway,but hope is in the air.。
