阅读理解(注:+表示A级文章;*表示B级文章;其他为C级文章)第十九篇Prolonging Human LifeProlonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease 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 and gathering cultures, old people who could not keep up might be left behind to die. 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 child. In most contemporary societies, people feel 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 retirement, 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, they 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 members 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 nonprofit groups. While a few of these institutions arc good, most of them are simply "dumping grounds" for the dying in which "care" is given by poorly paid, overworked, and under-skilled personnel.十九延长人类生命人类生命的延长使人口增加了。
2012年度职称英语“卫生类”新增阅读理解和完形填空全文翻译(3月26日)

2012年职称英语卫生类新增阅读理解第八篇 Eat Healthy"Clean your plate!" and "Be a member of the clean-plate -club!" Just about every kid in the US has heard this from a parent or grandparent. Often,it's accompanied by an appeal:" Just think about those starving orphans in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying "clean the plate", perhaps we should save some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies. A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently,some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve portions that are too large;23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions. Seventy percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25,000 want smaller.It's not that working class Americans don't want to eat healthy. It's just that,after long hours at low-paying jobs,getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck ,happy to save a little money for next year's Christmas presents.第八篇翻译健康饮食“把盘子里的东西吃完了!”“要成为一名清盘俱乐部的成员!”几乎每一个美国小孩都会听到父母亲或祖父母这样的唠叨。

Eat Healthy吃健康“清洁你的盘子!”和“清洁板俱乐部的成员!”只是在美国的每个孩子听到父母,祖父母或外祖父母。
通常情况下,它伴随着上诉:“试想想,在非洲的孤儿挨饿!”当然,我们应该感谢每一口食物。
不幸的是,在美国的许多人采取太多的叮咬。
而不是停留“清洁盘”,也许我们应该为明天保存一些食物。
据新闻报道,美国餐馆的部分原因归咎于日益增长的肚子。
一位服务员把一盘食物,在每个客户面前,用两到四倍由政府建议的数额,根据今日美国的故事。
美国人的传统与价值关联的数量和大多数餐馆尝试给他们。
他们喜欢有客户抱怨比太少而对过多的食物。
在宾夕法尼亚州立大学营养学教授芭芭拉·罗尔斯,告诉美国今天餐厅份量开始增长,在20世纪70年代,美国人的腰围开始扩大的同时。
健康专家们试图让许多餐馆为较小的部分。
显然,现在,一些客户要求这太。

大多数时候,这种感染是不活跃的。
但是每年大约有八百万结核病病例,通常是在肺部。
两百万人因此丧命。
结核病发病率由于艾滋病的传播和抗药型结核病的出现而增加。
目前的治疗至少需要六个月。
患病者不得不每日服用多种抗生素药品。
许多人在稍感舒适后就停止使用药品,这么做可能导致抗药性感染。
公共卫生专家一致认为针对结核病的速效治疗剂将会更加有效果。
现在有一项研究评估这种速效治疗剂究竟效力有多大。
这项研究由美国哈佛大学国际卫生方面的教授率领。
Joshua Salomon说,疗程较短的治疗计划可能不仅仅意味着更多病人被治好,也意味着将感染传给别人的病人会更少。
研究者们设计了一个数学模型来检测两个月治疗计划的效果。
他们以东南亚目前的结核病情况来检验这个模型。
科学家们发现两个月的治疗可以防止大约20%的新病例,也可能防止大约5%因结核病引起的死亡。
这个模型表明,如果速效治疗剂可以在2012年前研发出来并大规模使用的话,减少结核病例在2012年到2030年间就可以实现。
世界卫生组织在1990年制定了DOTS计划,DOTS意指短期直接观察治疗。
卫生工作者监督结核病人每天服药,以确信他们继续治疗。
今年年初,一个国际组织同盟宣布了一项扩大DOTS的计划。
这个十年计划也旨在资助新结核药品的研究。
现在四种最常用的药品也有四十多年的历史了。
全球结核病药物开发联盟宣称它的长期目标是找到一种治疗方法,可以通过十次剂量就效果。
2.节食普通人每天需要大约1,800卡的热量才能生存下来。
这些热量使你的心脏跳动、肺呼吸、身体器官正常运转、大脑持续工作,并可以使你保持足够的体温。
一个人体重增加了是因为他或她每天摄入的卡路里比需要的多。
