Question 19-22
There are many kinds of friends. Some are always ( 1 ) you, but don’t understand you. Some say only a few words to you, but understand you. Many people will step in your life, but only ( 2 )friends leave footprints. I shall always recall the autumn and the girl with the ( 3 ). She will always bring back the friendship between us. I know she will always be my best friend. It was the golden season. I could see the yellow leaves ( 4 )with the cool ( 5 ). In such a season, I liked walking alone on the roads covered with leaves, ( 6 )to the sound of them. Autumn is a ( 7 )season and life is uninteresting. The free days always get me ( 8 ). But one day, the sound of a violin ( 9 )into my ears like a stream flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was ( 10 )in playing her violin. I had ( 11 )seen her before. The music was so nice that I listened quietly. Lost in the music, I didn’t know that I had been ( 12 )there for so long but my existence did not seem to disturb her. Leaves were still falling. Every day she played the violin at the corner of the building ( 13 )I went downstairs to watch her performance. I was the only listener. The autumn seemed no longer lonely and life became ( 14 ). ( 15 )we didn’t know each other, I thought we were already good friends. I believe she also loved me. Autumn was nearly over. One day, when I was listening carefully, the sound suddenly ( 16 ). To my astonishment, the girl came over to me. “You must like music from the violin.” she said. “Yes. And you play very well. Why did you stop” I asked. Suddenly, a ( 17 )expression appeared on her face and I could feel something unusual. “I came here to see my grandmother, but now I must leave. I once played very badly. It was your listening every day that ( 18 )me.” she said. “In fact, it was your playing ( 19 )gave me a meaningful autumn,” I answered, “Let’s be friends.” The girl smiled, and so did I. I never heard her play again in my life. I no longer went downstairs to listen to her. Only thick leaves were left behind. But I will always remember the fine figure (身影) of the girl. She is like a ( 20 )―so short, so bright, like a shooting star giving off so much light that makes the autumn beautiful.

Questions 6-10 For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S. had acquired when it purchased Louisiana, and the Apollo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms as humanity’s next great terra incognita. And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet’s reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a, leading role The question naturally invites a couple of others.. Are there experiments that only humans could do on Mars Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe. The passage tells us that proof of life on Mars would ______.
