Today, I saw a video of a teenager giving shoes to one of his classmates. The day before, he had heard the student on the phone with her mother 1that she needed new shoes. Her mother 2said that she couldn't afford to 3 the Vans, but that she would buy new shoes in Walmart. He 4to go Vans that afternoon and buy the girl a new pair of shoes. The next day, in front of the class,5that a friend was recording the good deed, he6the new shoes to her.

    Let's start with the 7of the situation. The girl got new shoes, and the boy felt like his behavior was an act of8. But let's look at some of the results that he may not have9thought of. The girl could have been very 10. What's worse, it showed that her family was 11 which might set her apart from her classmates.

    Here's12 the situation should have gone. The boy could buy her new shoes,13give them to the teacher instead. The teacher could give them to the girl with 14. He should not have put the15on the Internet. The 16goes for donating to homeless people. Give them some respect and 17 it off the Internet.

    Doing a good deed is supposed to be18to someone else. But if you're doing it so that you can be popular on social media, you're doing it for the wrong19 The next time you 20to do something nice for someone, ask yourself why you really want to do it.

    “He who 4 is the owner,” William said in the 5 remarks of the cleanup event in 2000.“The Great Wall 6China, and is also one of the greatest 7 in the world.Everyone has a 8 to protect it.Every day should be Earth Day,” he said.

    During the past three decades, he has spent most of his time 9 and exploring the Great Wall and has developed his own 10 to protect the cultural relic.

    “It's a 11 thing that people are going out to enjoy themselves and to 12 the great history and heritage, 13 it's also quite dangerous if they don't 14 how fragile (易损坏的) the historical sites are and how fragile the 15 is,” William said.

    In 1989, his first 16Alone on the Great Wall was published, and he has published another five books about the Great Wall since then.In 2001, he 17 International Friends of the Great Wall, a(n)

    I worked in a restaurant. One night a woman came in with three small children. As a 1, I could usually tell who is going to tip well and who isn't going to tip at all I 2 got the latter vibe (气息) from her. She asked about the 3 of everything on the menu, but she ordered 4 water to drink. She wasn't 5 appetizers (开胃饮料). At one point her daughter asked her very politely: “Mom, can I have 6?” The woman pulled out her coin purse and 7 her change before saying yes. Then I was 8 that I wouldn't get a tip, but they were very nice and pleasant to 9so I didn't even think twice about it.

    At the end of the meal, she paid 10 in coins.

    When I went back to clear the table, to my 11, there were a lot of quarters left for me. They amounted to $ 8, or about 25% of the 12. Here was a woman who had to count her money before 13 her daughter a milk because she wanted to 14 she still had enough to tip me.

    Was it the largest tip I ever got? No, but it's the only one I 15 after all these years.

    This story is a 16 that the very best aspects of human nature can shine through in even the most 17 of everyday situations. The first 18 may be powerful, but it's important to let others show their true nature rather than making a snap (仓促的)19 about them. As a matter of fact, generosity is a valuable virtue, whether you 20 to be rich, poor, or somewhere in between.

The family had just moved to Rhode Island, and the young woman was feeling a little depressed on that Sunday in May. After all, it was Mother's Day—and 800 miles1 her from her parents in Ohio.

    She had called them that morning, to wish her a happy Mother's Day and her mother had2how colorful their backyard was3spring had arrived. Later, she told her husband how she4those lilacs (丁香花) in her parents' yard. “I know where we can find some,” he said, “Get the5and come on.” So off they went.

    Some time later, they stopped at a hill and there were lilacs all round. The young woman rushed up to the nearest6and buried her face in the flowers. Carefully, she7some. Finally, they returned to their car for the8home. The woman sat smiling, surrounded by her9.

    When they were near home, she shouted “stop”, got off quickly and10to a nearby nursing home. She went to the end of the porch (门廊), where a(n)11  patient was sitting in her wheelchair, and put the flowers into her lap. The two12, bursting into laughters now and then. Later the young woman turned and ran back to her  13. As the car pulled away, the woman in the wheelchair14with a smile, and held the lilacs15.

    “Mom,” the kids asked, “16did you give her our flowers?” “It is Mother's Day, and she seems so17while I have all of you. And anyone would be18 by flowers.”

    This satisfied the kids, but not the husband. The next day he19some young lilacs around their yard.

    I was the husband. Now, every May, our yard is full of lilacs. Every Mother's Day our kids20purple lilacs. And every year I remember that smile of the lonely old woman.

    In most people's eyes, I was a golden girl when I was eighteen years old： I was president of the college drama society, a member of the student senate and so on. I was the1of all my friends and I was in a state of 2 .

    The old Greek tragedies3us that when pride rises, punishment falls. My universe4 with great suddenness when the scenery(舞台布景道具）fell on my head and I was left almost5for the next four months.

    My memory was in a mess and within a few months all my 6 were taken away. I was even told that I would have to leave the college at the end of the spring term7clearly, I couldn't do academic work.”

    Sad, I took one last 8by Dr. Jacob Taubes. He was the most brilliant teacher I had ever 9and in his class, I began to raise a tentative 10 and ask an occasional question. He would answer with great intensity, and soon I found myself asking 11 I questions constantly.

    One day I was walking to the bus when I heard Dr. Taubes12me,” Miss Houston, let me walk with you. You know, you have a most 13mind.”

“Me? 1 have a mind?”

    “Yes, of course.” Then he asked my understanding of some problems discussed in the classes. From that day on, Dr. Taubes continued to 14 me to the bus, always15 me with intellectually vigorous questions. Within several weeks my eyesight came back and my spirit 16 .

    Though what I acquired from the accident was a 17 sense of life, I remain deeply 18 for the attention Dr. Taubes had shown. He 19 me when I most needed it. I swore then that I would try to 20 and acknowledge the unlucky person as I had been acknowledged.

    Four brothers left home for college, and they became successful doctors and lawyers.

    Some years later, they got together again. While having dinner, they1for a long time. They discussed the2they had given their elderly mother who lived far away in another city. The first said, "I had a3house built for Mama." The second said, "I had my Mercedes-Benz dealer (奔驰经销商) send a4to her." The third said, "I built a beautiful 5for Mama." The fourth said, "You know6Mama loved reading poems and you know she can't read any more because she can't 7very well. I met a businessman who had a parrot that can recite many8. It took him 12 years to9it to speak and he earns his living by renting it out. I had to pay him $100,000 a year for twenty years,10it is worth it." On hearing that, the other brothers were11by his good thought.

    After the holidays, their mother12 her thank -you notes, which read，"Milton, the house you built is so huge. I only live in one room, but I have to clean the whole house. It's a (an)13job. Thanks anyway." "Marvin, I am too old to14.I stay home and have others work for me, so I'll15 use the car. The 16was good, although not realistic. Thanks."

    "Michael, you gave me an expensive building for many people to17plays or I watch movies in it, but all my friends are dead. I've almost18my hearing and I'm nearly blind. I won't use it. Thank you all the same.

    "Dearest Melvin, you are the19 son to have the good sense to give a little thought to your gift. The chicken tasted so20. I liked it very much. Thank you."
