    I believe in miracles(奇迹) because I've seen so many of them. One day, a patient was referred to me who was one hundred and two years old.“There's a 1 in my upper jaw, ”she said. “I told my own dentist it's nothing, but he 2 I come to see you”

    Her eighty-year-old son accompanied her. He would 3 to add something, but she stopped him. She wanted to tell everything herself. I found a large cancer that spread over much of the 4 of her mouth. A careful examination later 5 that it was a particularly bad sort of cancer.

    During her next appointment, I explained to her the 6 of the problem. She clasped my hand in hers and said, “I know you're worried about me, but I'm just 7.”

    I thought otherwise. After considerable 8 on my part, and kindness on her part because she wanted to 9 me, she agreed to have me refer her to a cancer surgeon. She saw him, but as I expected, 10 treatment.

    About six months later she returned to my office, still energetic and 11.

    “How are you?” I asked.

    “I'm just fine, honey,” she responded 12 high spirits. “When can I get stared on fixing my dentures(假牙)?”

      Surprised to see her at all, I answered 13, “Let me take a look in your mouth and we'll see about it. ”

      I couldn't believe my eyes. The cancer that had 14 nearly the entire roof of her mouth was gone—only one small area of redness 15.

      I had read of such things happening, but had 16 seen them with my own eyes. That was my first miracle. Since then I've seen many others, because they keep getting 17 to see. In fact, miracles are daily events for me now. And people are a miracle, 18through them we have a chance to know ourselves and to 19 the miracles of one another.

      Since my first miracle, I;ve come to understand that the time and place for a miracle is 20 we choose to find it.

    Jenna, a popular girl from Westwood Middle School, had graduated first in her class and was ready for new 1 in high school.

    2, high school was different. In the first week, Jenna went to tryouts (选拔赛) for cheerleaders (拉拉队队员). She was competing against very talented girls, and she knew it would be 3 for her to be selected. Two hours later, the 4 read a list of the girls for a second tryout. Her heart 5 as the list ended without her name. Feeling 6, she walked home carrying her schoolbag full of homework.

    Arriving home, she started with math. She had always been a good math student, but now she was 7. She moved on to English and history, and was 8 to find that she didn't have any trouble with those subjects. Feeling better, she decided not to 9 math for the time being.

    The next day Jenna went to see Mrs. Biden about being on the school 10. Mrs. Biden wasn't as 11 as Jenna. “I'm sorry, but we have enough 12 for the newspaper already. Come back next year and we'll talk then.” Jenna smiled 13 and left. “Why is high school so 14?” she sighed.

    Later in 15 class, Jenna devoted herself to figuring out the problems that had given her so much 16. By the end of class, she understood how to get them right. As she gathered her books, Jenna decided she'd continue to try to 17 her new school. She wasn't sure if she'd succeed, but she knew she had to 18. High school was just as her mom had said: “You will feel like a small fish in a big pond 19 a big fish in a small pond. The challenge is to become the 20 fish you can be.”

    I found out one time that doing a favor for someone could get you Into a lot of1.I was having a final test at the time2the test, the girl sitting next to me 3something, but I didn't understand. So I 4over her way and found out that she was trying to ask me 5 I had an extra pen. I 6to have one,so I took it out and put it on her desk.

    Later, after the test papers had been 7the teacher asked me to stay in the room when all the other students 8As soon as we were alone, she began to talk to me about what it meant to 9up.She talked about how important it was to be 10for my own acts. For a long time, she talked about 11and emphasized(强调)the fact that when people do something dishonest,they are really cheating 12She made me promise that I would think 13 about all the things she had said,and then I could leave.I walked out of the room14why she had talked to me about all those things.

    Later on,I found out that she thought I had15 in the nest.When I leaned over to talk to the girl,it looked as if I was16answers from her test paper.I tried to17about the pen,but it seemed very 18to her that I hadn't talked of anything about it the day she talked to me.19I tried to explain that I was just doing the girl a 20I am sure she continued to believe that I had cheated on the test.

    Growing up in the 1960s, I was taught from an early age to send a handwritten thank-you note expressing 1 for kindness. My mother used to buy me a box of paper and 2 me in the art and value of saying “thank you”. She 3 to be right.

    A study showed that it took most volunteers less than 5 minutes to write the thank-you notes. Just 5 minutes to make 4 person feel “overjoyed”! 5, in our “instant” world, the idea of getting an actual pen and writing an actual note seems to never come to mind. We tend to do what is 6 for us — a quick text or an email.

    It's easy to use the 7 of being busy, but even very busy and 8 businessmen find time to 9 thank-you notes. For example, when Doug Conant became CEO of Campbell's Soup, the company had 10 half of its market value and morale(士气) was at an all-time low. He 11fixing that by doing some simple things that are probably not 12 in any MBA class. For one thing, Conant wrote to every 13. He gained their confidence and 14, turned the company 15.

    In his ten years as CEO, Conant wrote over 30,000 notes to employees. It's 16 not to ask how he did it. 17, he had many other things to do 18 writing a thank-you note. Conant made time for 19 because he knew the impact(影响) each one would have. An expression of 20 in this crazy world still makes a difference.

    My father was a highly educated, intelligent gentleman. He could debate or discuss for 1on almost any topic and hold your attention in the process. I thought there was 2 he wasn't able to do.

    A few days 3 my younger brother's 7th birthday, Dad planned to put together a shiny new 4 as a special birthday surprise. After nearly an hour of 5 the instructions, Dad was still unable to put the new bike together. Later he folded up the paper of instructions, 6 his tool box, and decided to take the bike back to the local toy store and pay extra money to have it 7 assembled(组装) there. Then, a(n) 8 came to him, as he called out to Lovett, the quiet little man who mowed our grassland.

    "Lovett, have you ever assembled a boy's bicycle?" As Lovett walked towards the bike, Dad handed him the paper of instructions. Lovett handed it 9 to him, saying," No, thanks. I can't read. When you can't read, you have to 10." Less than 15 minutes later, the new bicycle was fully assembled, with no spare parts 11. Dad shook Lovett's hand, patted him on the back, thanked him and hid the bike.

On the night after my brother 12 his simply new gift. Dad announced at the family dinner table 13 had happened several days earlier. He took great delight in telling it 14 —he used it as an example of thinking.

    He did not 15 illiteracy (文盲) , but strongly taught us to use our 16. The joke was on my father, 17 he was able to turn it into a learning tool, and I liked him even 18  after the incident. I also gained a respect for Lovett. To me he had always been the old yard man who didn't say much, but after that day, he seemed to smile 19 , even walk taller. It's amazing what a real nod of  20 can do to lift people up.
