Finally realizing that I was there, Rocky turned toward me with a sad smile. “I’m leaving tomorrow,” he said. “I know.” My voice was almost a whisper (低語). I was angry at myself for being so weak, but I wasn’t about to cry. “My flight’s early, so there’s no need for you to get up at 4 . just to e to the airport,” he said. Seeing the disappointed look on my face, he said quickly, “I promise (許諾) I won’t leave without saying goodbye.” I tried to say something, but didn’t. It’s always better to keep quiet if you’re about to cry. “You promised you wouldn’t cry,” he said. I remember the day he taught me how to ride a bike. At first I thought he was always right behind me, holding the seat to keep me from falling. I was happy with this arrangement (安排), but he knew he couldn’t hold me up all my life. He told me that one day he would have to let go. Suddenly afraid, I said that I would fall if he did. I rode down the street, asking him not to let go, only to turn around and realize that he had let go long before. He coughed, stopping my thoughts. What was left to say? How could I say goodbye to the person who taught me everything—from maths to boxing? The next morning I woke up, glanced（瞥一眼）at my clock, and realized he had left hours ago. We never even said goodbye. But soon I noticed a piece of paper on my desk. There was only one word—goodbye. Goodbye, Rocky. Although he may have been many miles away, I knew he heard me, even it was only an echo (回聲) in his heart.50. The elder brother felt ______ when he was leaving.

The things that we will be able to do in the twentyfirst century (since the year 2000) should help us live better lives in many ways, at home and at work, in our own country and around the world. Here are just some of them, put into five groups.PeoplePeople may live for up to 120 years and use new technology to help when people go blind, deaf and have other problems. The number of people over a hundred years old could go from 135,000 today to million people by 2050. By 2015 people think that 100 million workers will be able to work from home for a pany in a different country by using the Internet.MoneyWorldwide ebusiness will bee even more successful with online shops that sell special products for each person, which will be brought to their house the next day.EnvironmentThe technology for making energy from wind and the Sun is growing very quickly. In the future wind and Sun energy could bee much cheaper and many more countries could use it. This would be very useful in poor countries. The air in big cities would also bee much cleaner and healthier as a result.Society and culture The Internet will help to create more worldwide friendships. Families may spend more time together as people will be able to do 24hour online banking and shopping.Technology The new science of “nanotechnology” (very small robots or machines) will make all sorts of products smaller and lighter.
