【简答题】
. Once upon a time, there was a seed and because he was only a seed, nobody cared to notice him. Thus, feeling kind of inferior, the seed gave no importance to his existence. Then one day, a wind picked him up and threw him on an open field under the hot sun. He wanted to know why. But instead of any answer, he was provided with rain besides sunlight, sometimes small and sometimes heavy. Time flew and years later he saw a traveler sitting by his side. 'Thank God for this. I really need some rest,' he heard the traveler say. 'What are you talking about?' the seed soon asked. He thought the man was making fun of him. Sure, he had seen many people sitting by his side but no one ever spoke to him like that. 'Who's this?' the man was surprised. 'It's me. The seed.' 'The seed?' the man looked at the big tree. 'Are you kidding me? you're no seed. You're a big tree? 'Really?' 'Yes! Why do you think people come here? To feel your shade!' A moment passed before the traveler's words touched the chord (心弦)  in him. The seed, now a great tree, smiled for the first time in his life. Years of sufferings from the sun and the rain finally made sense to him. 'Oh! That means I'm not a small seed anymore!  I didn't die unnoticed but was born to help people with tiredness. Wow! Now that's a life worth a thousand gems (宝石)!' 60. What does the underlined word 'inferior' (in Paragraph 1) probably mean? A. Not funny.     B. Not weak.   C. Not good.  D. Not interesting. 61. The seed thought the man sitting by his side was laughing at him because _______. A. the man didn't think the seed was important B. the seed never thought he could be noticed C. the man was talking about God with him D. the man really wanted some rest near him 62. When the seed first heard that he had been a big tree, he felt _______. A. disappointed        B. excited    C. doubtful       D. satisfied 63. The passage mainly tells us that ________. A. every life is of some value           B. one's existence is in need of a finder C. life goes on no matter what happens    D. failure is the mother of success
