Harrison had worked and lived in the Mediterranean for many years b (92) he returned to England. Harrison had often dreamed of retiring in England , his hometown ,where he spent his childhood happily, he had p (93) to settle down in the country. He had no sooner returned in July than he bought a house and went to live there. Harrison had thought of everything e (94) the weather. Almost immediately he began to complain about the weather, for even though it was still s (95) ,once the most sunshiny days of this period with his schoolmates playing outside during their holidays, it rained continually and it was often bitterly cold.After so many years of e (96) the sunshine in the Mediterranean, Harrison got a shock. He acted as if he had n (97) lived in England before. In the end, Harrison had to admit that the weather of his hometown was more than he could bear. He had h (98) had time to settle down when he sold the house and left the country. The dream of my poor friend had had for so many years ended there.( E )From the first day he entered my junior-high classroom, Willard P. Franklin existed in his own world, shutting out his classmates and teachers. Even a “Good Morning, Willard” from me, his class teacher, received only a word“Morning”. His classmates could get the same reply, too . Willard was completely a loner who seemed to have no desire or need to break his barrier (障碍) of silence.Shortly after the Thanksgiving holiday, we received the word of the annual Christmas collection of money for the less fortunate people in our school district.“Christmas is a season of giving,” I told my students. “There are a few student s in the school who might not have a happy holiday season. By contributing to our Christmas collection, you will help buy food, clothing and toys for these needy people. We start the collection tomorrow.”When I called for the contributions the next day, I discovered that almost everyone had forgotten, except for Willard P. Franklin. The boy dug deep into his pants pockets as he strolled up to my desk. Carefully, he dropped two quarters into the small container.“I don’t need any milk for lunch,” he said very quietly. For a moment, just a moment, he smiled. Then he turned and walked back to his desk.After school, I took our meager (少量的) contributions to the school principal. I couldn’t help sharing the incident that had taken place.“I may be wrong, but I believe Willard might be getting ready to become a part of the world9around him,” I told the principal.“Yes, I believe it sounds hopeful,” he nodded. “And I think that we might do well to have him share a bit of his world with us. I just received a list of the poor families in our school who most need help through the Christmas collection. Here, take a look at it.”As I gazed down to read, I found Willard P. Franklin and his family were the top names on the list.Answer the questions(根据短文内容回答下列问题): ( 14分)99. Which word did Willard P. Franklin’s teacher and his classmates get from him?100.
