__________________________________________________________________________________________ Going hungry is a major contributor to ill health, particularly among children, and a new report reveals how long-lasting the damage can be. Researchers at the National Cancer Institute (NCI) and the University of Calgary performed the first longterm study on the【C1】______of hunger on general health,【C2】______children from birth to 21 years. Most studies to date have【C3】______only snapshots of childhood health,【C4】______the short-term impact of hunger【C5】______a period of time. In the new analysis, the scientists found that children who went hungry at least once in their lives were 2i-times more likely to have【C6】______overall health 10 to 15 years later, compared with those who never had to【C7】______food. "Our research shows that hunger and food insecurity are really damaging【C8】______children"s life chances," says lead author Sharon Kirkpatrick, a visiting fellow at NCI. The study supports earlier findings that【C9】______episodes of hunger are more likely to cause ill health than an isolated experience of starvation: children in Kirkpatrick"s analysis who experienced two or more periods of hunger were more than four times as likely to report ill health than those who never went hungry. The relationship, she says, remained strong even after the team accounted【C10】______other factors that could influence health, such as age, sex and household characteristics like income. 【C11】______one experience of hunger can have lasting effects on a child"s health, a fact that is especially troubling in light of the sobering rise in U.S. households that were【C12】______to do without food in 2008: 15% of American families reported some【C13】______in the amount or quality of food they consumed,【C14】______from 11% the previous year. 15 this study did not probe into the【C16】______mechanism by which hunger affects long-term health, Kirkpatrick【C17】______that both psychological and physiological factors may be at work. Aside from the obvious negative impact that missing key nutrients and calories can have on growth and development, she says, the psychological【C18】______of food insecurity—not being able to afford a【C19】______and high-quality source of food —can be【C20】______to youngsters as well.(分数:40.00)

(10 points) Weighing yourself regularly is a wonderful way to stay aware of any significant weight fluctuations. 1 , when done too often, this habit can sometimes hurt more than it 2 . As for me, weighing myself every day caused me to shift my focus from being generally healthy and physically active to focusing 3 on the scale. That was had to my overall fitness goats. I had gained weight in the form of muscle mass, but thinking only of 4 the number on the scale, I altered my training program. That conflicted with how I needed to train to 5 my goals.

It takes about three weeks to a month to notice any significant changes in your weight 7 altering your training program. The most 8 changes will be observed in skill level, strength and inches lost. For these 9 , I stopped weighing myself every day and switched to a bimonthly weighing schedule 10 . Since weight loss is not my goal, it is less important for me to 11 my weight each week. Weighing every other week allows me to observe and 12 any significant weight changes. That tells me whether I need to 13 my training program. I use my bimonthly weigh-in 14 to get information about my nutrition as well.

The 17 to stop weighing myself every day has done wonders for my overall health, fitness and well-being. I’m experiencing increased zeal for working out since I no longer carry the burden of a 18 morning weigh-in.

2017考研英语二完形填空真题

2017考研英语二完形填空真题 Would a Work-Free World Be So Bad? Fears of civilization-wide idleness are based too much on the downsides of being unemployed in a society premised on the concept of employment. A 1567 painting by Pieter Bruegel the Elder depicts a mythical land of plenty, where people grow idle in the absence of work. Wikimedia Ilana E. Strauss Jun 28, 2016 People have speculated for centuries about a future without work, and today is no different, with academics, writers, and activists once again warning that technology is replacing human workers. Some imagine that the coming work-free world will be defined by inequality: A few wealthy people will own all the capital, and the masses will struggle in an impoverished wasteland. A different, less paranoid, and not mutually exclusive prediction holds that the future will be a wasteland of a different sort, one characterized by purposelessness: Without jobs to give their lives meaning, people will simply become lazy

2018考研英语一、二新题型及完型深度 解析 各位参加2015年考研考试的亲爱学子大家好,这次考试英语顺利的落下了帷幕,大家特别关心今年新题型和完形填空,我用一点时间讲讲新题型和完形填空的情况。 {C}一、{C}新题型考察简单 {C}1、{C}英语一:段落句子填空题 首先完形填空新题型纯粹是波澜不惊,他基本上保持了考研英语命题稳健的基本优点。今年在考试过程中,我们说不管是英语一还是英语二的题型,基本上让广大的考生考出自己的水平。 另外,今年的题型比较简单。比如说在2014年初考试的时候,英语一的新题型考到了培训,而这次新题型考的是常见的段落句子填空题。 这篇文章出题风格和往年不一样,往年往往是五个独立段落,或者是在某一段的最后一段出一道题,比如说42题、43题,都是在我们的段尾出题,但是41、44、45都是段落中间出的题,这一点在降低难度,而不是在提高难度。 这篇文章注意一下来自于马丁所著的一本书《阅读的方法》讲的是高级阅读技巧,这本书的第一单元就是这个。 以下是英语一新题型参考答案: 41题正确答案选的是C。非常简单,只要找到这篇文章只要对一下就全出来了。这里我们说最主要的是这句话,对于这句话我们41题选择的是C,在这里这个词它也可以对应后面的句子。 42题是E。你可以做进一步的推理,关于这个课文的重要。我们之所以选择E,因为E 空前的两句都重复了“推理”这样的字眼。还有E段的最后也提出了读者的推测。所以选择E。 43题是G。这个考点和去年的考点差不多。 44题是B。B选项的意思是因素。 45题是A。A具体描述了许多不同的阅读路径和方式,这是对45空前后的细化。 2、英语二:小标题题 对于英语二的新题型这次考的小标题题,这一点老师们和同学民都预测到了,而今天考的小标题题又是简单的。 这里说一下英语二的新题型。今年考的是要小标题题,这篇文章选自外国网站上的文章。他讲的是能够帮助你渡过困难时刻的一些古老的秘诀,能够帮助你渡过人生比较困难的时刻。 对于这篇文章相对来说比较简单,我们找到了这篇文章在网站上的出处,你会发现我们的命题人越来越中规中矩。我们知道命题人在很大的程度上要和全国160万的考生斗智斗勇,他不能有太多的把柄和错误被广大的考生抓住,所以你会发现今年的这篇文章在报刊上

2010 Copying Birds May Save Aircraft Fuel Both Boeing and Airbus have trumpeted the efficiency of their newest aircraft. The 787 and 350 respectively . Their clever designs and lightweight composites certainly make a difference . But a group of researchers at Stanford University , led by Ilan Kroo , has suggested that airlines could take a more naturalistic approach to cutting jet-fuel use and it would not require them to buy new aircraft. The answer, says Dr Kroo , lies with birds . Since 1914, scientists have known that birds flying in formation-a V-shape-expend less energy. The air flowing over a bird ’w sings curls upwards behind the wingtips . a phenomenon known as upwash. Other birds flying in the upwash experience reduced drag, and spend less energy propelling themselves . Peter Lissaman, an aeronautics expert who was formerly at Caltech and the University of Southern California ,has suggested that a formation of 25 birds might enjoy a range increase of 71%. When applied to aircraft, the principles are not substantially different . Dr Kroo and his team modeled what would happen if three passenger jets departing from Los Angeles, San Francisco and I as Vegas were to assemble over Utah, assume an inverted V-formation occasionally change places so all could have a turn in the most favourable positions , and proceed to London. They found that the aircraft consumed as much as 15% less fuel (coupled with a reduction in carbon-dioxide output). Nitrogen-oxide emissions during the cruising portions of the flight fell by around a quarter. There are , of course , knots to be worked out . One consideration is safety , or at least the perception of it . Would passengers feel comfortable travelling in companion? Dr Kroo points out that the aircraft could be separated by several nautical miles , and would not be in the intimate groupings favoured by display teams like the Red Arrows , A passenger peering out of the window might not even see the other planes. Whether the separation distances involved would satisfy air-traffic-control regulations is another matter, although a working group at the International Civil Aviation Organisation has included the possibility of formation flying in a blueprint for new operational guidelines. It remains to be seen how weather conditions affect the air flows that make formation flight more efficient. In zones of increased turbulence, the planes ’wakes will decay more quickly and the effect will diminish. Dr Kroo says this is one of the areas his team will investigate further. It might also be hard for airlines to co-ordinate the departure times and destinations of passenger aircraft in a way that would allow them to gain from formation flight. Cargo aircraft, in contrast, might be easier to reschedule, as might routine military flight. As it happens, America ’asrmed forces are on the on case already. Earlier this year the country ’D sefence Advanced Research Projects Agency announced plans to pay Boeing to investigate formation flight, though the programme has yet to begin . There are reports that some
