| Directions: For each blank in the following passage there are 4 words or phrases marked A, B, C and D. Fill in each blank with a word or phrase that best fits the context. One day, when I was a freshman in high school, I saw a kid named Kyle from my class walking home from school with all of his books. I thought to myself, "Why would he bring home all his books for the weekend? He must really be 1 ." As I was walking, I saw several kids running toward him. They ran at him, knocking all his books out of his arms and he fell down in the dirt. His glasses went 2 and landed in the grass about ten feet away from him. My 3 went out to him. So, I ran over to him. As I handed him his glasses, he looked at me and said, "Hey, thanks!" I helped him pick up his books, and asked him where he lived. As it turned out, he lived near me. We talked all the way home. He turned out to be a pretty 4 kid. Over the next four years, Kyle and I became best friends Kyle was the top student of our class, one of those guys that really found themselves during high school. He had to prepare a speech for 5 . On the graduation day, I could see that he was 6 about his speech. So, I patted him on the back and said, "Hey, big guy, you'll be great!" He looked at me and smiled. At graduation, he cleared his throat, and began. "Graduation is a time to 7 those who helped you make it through those 8 years. Your parents, your teachers, but mostly your friends. I am here to tell all of you that being a friend to someone is the best gift you can give them. I am going to tell you a story." I just looked at my friend with 9 as he told the story of the first day we met. He had planned to 10 himself over the weekend and was carrying his stuff home. He looked at me and gave me a little smile. "Thankfully, I was saved. My friend saved me from doing the unspeakable." Not until that moment did I realize that you should never underestimate (低估) the 11 of your actions. With one small gesture you can 12 a person's life. For better or for worse.
