The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.

    Not all cases of Alzheimer's disease look like this, but Alzheimer's is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages; people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs.

    While no one is certain what causes these changes in the brain's nerve fibers, their effect is certain. Alzheimer's destroys not only the patients, but also spouses（配偶）, friends and families.

    What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer's disease. Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis（诊断）and treatment may delay some of the most serious effects.

    What feeling will you likely experience if a loved one suffers from Alzheimer's disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn't remember you are married.

    Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

       ①夜色凄冷，阵阵江风袭来，她不禁打了个寒颤。

       ②一年前，她禁不住好友的怂恿，拿出所有的积蓄和朋友合伙开了一家火锅店。生意本来红红火火，不料厨师的一次失误，导致两位顾客食物中毒。尽管她们第一时间为对方治疗，火锅店的声誉还是受到了影响，顾客开始越来越少。关键时刻，好友撤资，一走了之，她内心十分痛苦。

       ③风更大了，她走到自己的汽车前面，竟发现一个十一二岁的小男孩趴在车前睡着了，手里拿着一个脏兮兮的蛇皮口袋，看样子是捡废品的。

       ④她轻轻摇醒小男孩：“你怎么趴在这里睡觉？”男孩揉揉眼睛问：“阿姨，您丢东西了吗？”她下意识地一摸口袋，手机居然不见了！小男孩见状，拿出一部手机，笑着说：“这是您的吗？”原来，小男孩捡废品时，在汽车旁边发现了这部手机，为了物归原主，他耐心等待，竟睡着了。

       ⑤真是个好孩子！他要捡多少废品才能换一部手机？她非常感动，问道：“天晚了，你一个人在这儿不怕吗？”男孩笑着说：“没啥怕的，每天放学后我都来，为了赚学费呀！”

       ⑥原来，男孩的母亲是聋哑人，他还有一个妹妹，一家四口人的生活全靠父亲打零工维持。男孩为了减轻家里的负担，就利用放学的时间出来捡废品 她看了看他的蛇皮口袋，里面放着几个饮料瓶子。她忽然想起来，放在汽车后备箱里的空饮料瓶还在。她赶快从后备箱里搬出来，又找出车内散落的旧报纸和杂志，全倒在男孩的蛇皮口袋里。男孩开心地笑了。

       ⑦风停了，她感到了一阵温暖。不久，重拾希望的她关了原先的店，筹钱开了一家新的火锅店。从那时开始，不管生意好坏，她都坚持资助小男孩上学，直到他大学毕业。男孩能自食其力了，他走过很多地方，尝试过很多工作，不管收入如何，他都会拿出一笔钱打到她的账户中。她把那些钱又重新汇给男孩，并打电话告诉他不必这样做，因为她出资援助他，完全是因为他的善良，根本不求回报。

       ⑧又过了几年，因房子要拆迁，曾经红火的火锅店生意再次变得冷清，最艰难的时候她甚至付不起房租。正在她心急如焚之际，小城电视台的记者忽然跑来采访她。原来当地的小学收到一笔捐款，捐款人正是她。她沉思了片刻，很快就明白，这件事的幕后策划者一定是男孩。这条新闻播出后，很多人被她的善良感动了，宁肯绕很远的路，也要到她的店里来吃饭，火锅店的生意很快又好转起来。

       ⑨重新赚到钱的她，十分感激所有帮助过她的人，继续资助贫困孩子。每次捐款，她总写下那个男孩的名字。其实，对她和男孩来说，写谁的名字已经不重要，重要的是，在他们手中，善心如一簇小小的火苗，正在悄悄传递，它无法照亮整个世界，却温暖了很多人的心。
