2、crease in death rates, not an increase in birthrates, that has led to the population explosion. prolonging human life has also increased the dependency load. in all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. in hunting

4、el a moral obligation to keep people alive whether they can work or not. we have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. unless these people were able to save money for their r

5、etirement, somebody else must support them. in the united states many retired people live on social security checks which are so little that they must live in near poverty. older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, th

6、ey must often go on welfare if they have a serious illness. when older people become senile or too weak and ill to care for themselves, they create grave problems for their families. in the past and in some traditional cultures, they would be cared for at home until they died. today, with most membe

7、rs of a household working or in school, there is often no one at home who can care for a sick or weak person. to meet this need, a great many nursing homes and convalescent hospitals have been built. these are often profit-making organizations, although some are sponsored by religious and other nonp

9、valescent dj.康复的sponsor v. 发起，资助institution n. 机构注释:1. prolonging human life has increased the size of the human population:延长人类生命的结果使得人口的数量有了增加。句中的 prolonging human life是动名词短语。由动名词短语作句子的主语时，句中动词必须用单数形式。如 : collecting stamps is his hobby.2. many people alive today would have died of childhood diseas

10、es if they had been born 100 years ago:如果今天活着的很多人生于一百年以前，他们会死于各种儿童疾病。3. because more people live longer, there are more people around at any given time:因为有更多的人寿命更长，所以在任何一个特定的时间里的人也就更多。4. the dependency load: 抚养人口数量。5. in times of famine: 在饥荒年代6. go on welfare : 靠福利救济go on 有许多意思，其中的一个意思是依靠过活。例:many p

16、es, not an increase in birthrates, that has led to the population explosion. 事实上，是由于死亡率的下降，而不是出生率的上升，导数了人口爆炸。因此，选项 c是正确答案。2. b 第二段第四句说： in times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another

17、 child. 在灾年，可能会容忍婴儿死亡，因为，如果他们的父母饿死了，他们也无法生存，而如果父母生存下来可重新生儿育女。因此，选项 b是正确的答案。3. a 第二段倒数第二句是这么说的：in the united states many retired people live on social security checks which are so little that they must live in near poverty. (在美国，许多退休人员依靠社会保障金生活，其数额之小差不多使人穷困潦倒。)可以看出，在美国许多退休人员的生活是很艰难的。这正是选项a表达的意思，因而选项a

18、是正确的答案。4. d 第三段第三句：today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. (当今，由于家庭中大多数人都出去工作或上学，家里常常没有人来照顾有病或虚弱的人。)this need 出现在下面这个短语中：to meet this need(为了满足这种需要)，它指句子前面的care for a sick or weak person。这正是选项d表达的意思。5. d文章昀后一

19、句说 : most of them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and under-skilled personnel.大多数机构只不过是倾倒垂死的人的垃饭场，所谓的照顾都是由收入低、超量工作、技术水平低下的人员提供的。作者如此措辞显然是对大多数机构的强烈批评。因此，选项 d是正确答案。第十八篇exercise can replace insulin for elderly diabetics most older people with

23、sor3 dr. flemming dela of the muscle research center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non?exercising persons. this means that the insulin works just as well for both groups. physical exercise cannot cure people of diabetes,

52、se levels.答案与解释 :1. a文章第一段告诉我们，科学新发现进一步支持了一种理论，即，当人体进入睡眠状态时，大脑对在白天形成的记忆进行组织和储存。 to sleep. perchance to file?见注释 1和注释 2。2. c 第二段告诉我们，科学家分析了老鼠的脑电波，尤其是从 somatosensory neocortex和 hippocampus两个区域发出的脑电波。该段是后两句指出，这两个大脑区域的活动是互相作用的。第二段并没有说 somatosensory neocortex或 hippocampus起主导作用。3. d 该段倒数第二句提供了答案。4. b 第四段的

53、后一句中 their brain scans，指上句中的 subjects 5. d 锻炼身体和体重控制能保持葡萄糖水平，闲此，去健身房就有了另外一个理由。睡眠促使记忆归档存储睡觉，说不定就是在整理归类记忆？刊登在最近网上出版的国家科学院文献汇编上的新发现 进一步证明了这个理论：当人体的其他部分在鼾声中安眠时，人体大脑就在整理和储存着甶天形 成的记忆。类国新泽西州立大学的乔治? buzsaki和他的同事们分析了睡眠中的老鼠和田鼠的脑电波。他 们特别研究了发源于学习记忆中心大脑知觉新皮层（处理知觉信息的区域）和海马状的电流 活动。科学家们发现，这两个区域的脑电波变化仿佛处于交织状态。而数十毫秒后

54、海马状突起发 出的波动将紧跟茬所谓的睡眠纺锤体（新皮层上的种种活动）。这对科学家们假设这两个大脑区 域的互动是理解增强记忆的关键。接下来的研究，同样也是刊登在这周网上出版的国家科学院文献汇编中，是关于与年龄相关 的由于葡萄糖浓度过高引起的记忆衰退。之前的一项研究表明，患糖尿病的人一直受到记忆衰退的困扰。纽约大学医学院的安东尼? 康威特及其同琪在一项新的工程中研究了 30个平均年龄69岁的人，以调查是否血糖浓度，随着 年龄增长而増长，同样会影响健康人的记忆。科学家们实施了回忆测试、脑部扫描和葡萄糖耐s 测试，以便测狱出人体组织从血液中吸收糖分的速度。这组科学家发现，与最次的记忆相对的， 是最低的

55、葡萄糖耐?：。此外，他们的脑部扫描也显示出海马状突起的缩小要比那些更容易从血液 中吸收糖分的人明显。“我们的研究表明，这种海马状突起的缩小对随着人类年龄增大而出现的记忆衰退有着不可 忽视的影响，硪威特指出，“这一发现大大提高了令人兴奋的可能性，即，不断改善葡萄糖耐诳 可以完全改变对某些与年龄相关的认知问题。身体锻炼和体重控制能限制葡萄糖浓度，由此，我们有了另外一个去健身房的理由。第二十六篇obesity: the scourge of the western world obesity is rapidly becoming a new scourge of the western world

56、, delegates agreed at the 11th european conference on the issue in vienna wednesday to saturday. according to statements before the opening of the conferenceof 2,000 specialists from more than 50 countries1.2 billion people worldwide are overweight, and 250 million are obese. professor bernhard ludvik of vienna general hospital said: “obesity is a chronic illness. in germany, 20 per cent of the people are already affected, but in japan only one per cent. ” but he said that there was hope for sufferers thanks to the new s
