    It has been some time since(自从) Jack saw the old man. In fact, Jack moved away from the country and was busy 1his work. There, Jack had2 time to think about the past and often had no time to 3 with his wife and son. He was working for his future.

    One day, his mother 4him over the phone that Mr Belser, their neighbour had died and the funeral(葬礼) would be 5Wednesday.It took a long time 6 Jack gave an answer because he had not thought of Mr Belser for a long time. “Well, he didn't 7 you. Every time I saw him, he'd ask 8you were going. He'd 9the days you spent with him, ” Mum told him.

    It had been about two weeks since Mr Belser died. One day, Jack 10 a package(包裹). There, inside was a gold 11.The box was from Mr Belser. Jack's hands shook(晃动) as he read the note inside. “Upon my death(死亡) please give this box to Jack Bennett. It is the thing I value most( 珍视) in my life.” There inside he 12 a beautiful gold packet watch. He opened the cover. Inside he found these words, “Jack, thanks for your 13 !——Harold Belser.”Jack held the watch for a few 14, then called his office and canceled (取消) his meetings for the next two weeks. He needed some time to spend with his wife and son.

    No matter how( 无论怎么样) busy we are, we should always remember to spend some time with the person we love. They are 15part of our life.

阅读下列文段，完成后面练习题：

    彗星主要是由冰构成的──水（H2O）冰，还有少量的甲烷（CH4）冰和一些氨（NH3）冰。在撞击地球的大气层时，一个中等大小的彗星碎片会产生一个白炽的火球和一种巨大的冲击波。火球会烧毁树木，冲击波会扫平森林，它的声音还会波及全球。但是这样的彗星不太可能在地上撞出一个环形山。彗星上的冰块在进人大气层的时候全部融化了，因此不会幽灵般地出现，这种现象令人不安地向人们关于宇宙是万古不变、井然有序这一观念进行挑战。如果那条天天随着星星起落的壮丽的乳白色光带是无缘无故地出现在那里，与人间世事毫无关系，那简直是不可思议的。因此出现了这样的观点：彗星是灾难的预兆，是神谴的预兆──它们预示了帝王的终日，王国的崩溃。对于彗星，巴比伦人认为是天髯，希腊人认为是垂发，阿拉伯人认为是燃烧的剑。在托勒密时代，人们根据彗星的形状把它们分类为“梁”、“喇叭”。“坛子”等。托勒密认为彗星给人类带来战争、炎热的气候和“动乱”。中世纪的一些彗星图看上去像未探明的飞行的十字架。一个名叫安德烈亚斯·西利奇厄斯的马格迪堡路德教主管人（即主教），在1578年发表了一篇题为“新彗星的科学启示”的文章。他在文章中。提出了一个独特的观点，他说彗星是“人类罪恶的浓烟，每天、每时、每刻都在升腾，它在上帝面前丑态百出、胆战心惊，逐渐地由浓烟形成长着卷发梳着辫子的彗星，最后被天国最高法官的怒火烧着了”。但是另一些人反驳说，如果彗星是罪恶的浓烟的话，天空势必乌烟滚滚。
