On a cold winter evening, I was walking home, tired and hungry, when suddenly came screams(呼喊声) from behind some tress.1 ， I slowed down to listen, and 2 that what I was hearing were the sounds of a fight. A woman was being3not far from where I stood.

    “Should I go to help her？” I thought. I was worried about my own 4 ， and I regretted having suddenly decided to take a new way home that night.“What if I am5too? Shouldn't I just6to the nearest phone and call the police？” But already the girl's7were growing weaker. I knew it was time for me to act fast because I could not8the life of this unknown woman，9 it meant risking my own life.

    I am not a 10 man. I didn't know where I found the11and physical strength(体力), but once I had finally12to help the girl, I became suddenly changed. I ran behind the bushes and 13the attacker off the woman. Struggling, we fell to the ground, where we fought for a few minutes 14the man jumped up and ran away.

    15 heavily，I stood up and came up to the girl, who was crying behind a tree. In the 16 ， I could not see her clearly, but I could certainly17her shock. Not wanting to frighten her any further, at first I spoke to her from a distance.

    “It's OK，” I said 18.“The man ran away. You're safe now.”There was a long stop and then I heard the words, said in both wonder and 19“Dad, is that you？” And then, from behind the tree, stepped my youngest 20 ， Katherine.

    We have been driving in fog all morning, but the fog is lifting now. The little seaside villages are1one by one. “There is my grandmother's house,” I say2across the bay to a shabby old house.

    I am in Nova Scotia on a pilgrimage(朝圣) with Lisa, my granddaughter, seeking roots for her, retracing(追溯)3 memory for me. Lisa was one of the mobile children4 from house to house in childhood. She longs for a sense of5and so we have come to Nova Scotia where my husband and I were born and where our ancestors6for 200 years.

We soon7 by the house and I tell her what it was like here, the memories8back, swift as the tide (潮水).

    Suddenly, I long to walk again in the9 where I was once so gloriously a child. It still10 a member of the family, but has not been lived in for a while. We cannot go into the house, but I can still walk 11 the rooms in memory. Here, my mother 12 in her bedroom window and wrote in her diary. I can still see the enthusiastic family13 into and out of the house. I could never have enough of being 14 them. However, that was long after those childhood days. Lisa15 attentively as I talk and then says, “So this is where I16 where I belong.”

    She has17 her roots. To know where I come from is one of the great longings of the human18 To be rooted is “to have an origin”. We need19origin. Looking backward, we discover what is unique in us; learn the 20 of “I”. We must all go home again—in reality or memory.

    Since I was young, my parents have encouraged me to watch the news every day to learn about major events in the world. And at school, my teacher urges us to study 1 so that we can one day become "global citizens".

    2, does simply having the skill of commenting on world affairs in fluent English make one a citizen of the 3? My experience in this summer school inspired me to 4 the answer, which would have been "Yes" if you had asked me this question earlier.

    In July, I 5 the PLE—Political science, Law and Economics—a session at the Yale Young Global Scholar Program. We had about 230 students 6 and about 45 percent of us were 7 students.

    We enjoyed lectures 8 by Yale professors and students. I was 9 with how the speakers stood on the stage. But more importantly, it was their 10 that impressed me most and made my experience in Yale especially 11.

    I talked to students from all over the world: a Palestinian girl told me the real living 12 of refugees (难民) in her country; a Greek guy 13 me to his country's government and people's attitude toward the debt crisis; a Mexican boy 14 the story behind his national flag, and how his country gained independence with me.

    By talking to them, I found myself opening a gate to a whole new world. I suddenly realized even if we're able to 15 different media and discuss world affairs in English, we're still 16. What really makes us think "internationally" is how we engage in 17 with people from different backgrounds and how we 18 their identities and opinions.

    If you were to ask me the question again, my answer would 19 be "No". To really 20 yourself a global citizen, open-mindedness and empathy are the real key.

    When I was growing up, I had an old neighbor Dr Gibbs, a good doctor. When Dr, Gibbs wasn't 1lives, he was planting trees. His house covered an area of ten acres, and his life's2was to make it a forest.

    The good doctor had some interesting theories 3plant care and growth. He never4his new trees, which went against traditional practices. Once I asked why, he said that watering plants did 5to them so that their later generation would grow weaker and weaker. So you had to make things6for them and removed the7early on. He talked about how watering trees made for8roots, and how trees that weren't watered had to grow deep roots9 moisture(水分). He meant that deep roots had to be10. For this reason, he11watered his trees.

    Dr Gibbs12a couple of years after I left home. Every now and again, I walked by his house and looked at the13that he had planted when he was alive. They're extremely tall and big14 they have deep roots now. However, the trees in my garden15 in a cold wind although I had watered them for several years.

    It seems that suffering 16these trees, while comfort and ease never can. I stood there deep in17.

    Every night before I go to bed, I check on my two sons. Mostly I pray that their lives will be 18.But I think that it's time to19my prayer because now I know my children are going to20hardship.

About two weeks ago I saw a very sad, blue eyed, homeless man sitting outside my local coffee house. I said, "Hi! How are you doing today?"

He seemed shocked that I was talking to him. "Not very well, " he replied. He began to tell me how he had been hit by a car while riding his bike. He had been in the hospital for a month and s rest home for another month. During that time the person that paid for his SSI checks （社保费） died of a hear attack and his wallet was stolen with all his IDs. He had several checks waiting for him but had no ID and therefore no access to his money. 

I decided that if this was all true I'd like to help him get a copy of his birth certificate and social security card. I asked him to meet me at the Department of Vital Statistics at 11: 00 p. m. The next morning I didn't see him so I started filling out the paperwork. I explained to the receptionist, "I'm trying to help a homeless friend get his ID hack. " "Bob?" she inquired. "Yes, Bob, " I responded, surprised that she knew his name. "He was here at 9: 30 and he just left, she said, "But he told us you were coming. " I paid the fee and walked out with Bob's Birth Certificate. 

As I was driving home I saw Bob riding back on the old bike someone had given him. I pulled over and jumped out of my car shouting, "Bob! Bob! I got it!" He saw me and rode over. "I got it, Bob! Look, here it is!" He got tears in his eyes and told me I was his guardian angel. 

A few days later I needed him to meet me at the Social Security Office. It took me a half hour to get there by car and at least two hours by bike. But there he was sitting on the sidewalk waiting for me! We were in the Social Security Office for two hours. We got everything straightened out and by next week he will have received his back pay, which is a substantial sum. 

Yes, one person can make a difference in this world. And the interesting thing is that I am getting as much, if not more, from this experience than Bob. I am deeply touched by Bob's sensitivity, his gratitude, his stories, his heart. 

Home is where the heart is, even for the homeless!
