阅读理解。 An old farmer lived with his grandson. Each morning, the 1 got up early and read his Bhagavad Gita (薄迦梵歌). One day the grandson asked, 'Grandpa! I try to read the book like you 2 I can't understand it, and I forget it easily. What's the 3 of reading it?' The grandfather said, 'Take this coal (煤炭) basket down to the 4 and bring me back a basket of water.' The boy did as his grandfather 5 , but all the water ran 6 he got home. The grandfather laughed, 'You'll have to move faster next time.' This time the boy 7 faster, but again the basket was empty. He told his grandfather that is was 8 to carry water in a basket. He wanted to use a bottle instead, but the old man said, 'I just want a basket of water. You're not 9 hard enough.' The boy wanted to show his grandfather that the water would surely run. He again put the 10 into the river and ran hard. But there wasn't anything in it again. He said 11 ,'Look, grandpa, it's useless!' 'Watch the basket.' said the grandfather. For the first time the boy 12 the basket was different. It had changed from a dirty old coal basket into a 13 one, inside and out. 'Boy, you might not understand or remember 14 when you read the book, but when you read it, you will be 15 , inside and out. That's what you got from it.' (     )1. A. son (     )2. A. so (     )3.
