Poor nations to bear brunt as world warms

The world s richest countries, which have contributed by far the most to the atmospheric changes linked to global warming, are already spending billions of dollars to limit their own risks from its worst consequences, like drought and rising seas.

But despite longstanding treaty commitments to help poor countries deal with warming, these industrial powers are spending just tens of millions of dollars on ways to limit climate and coastal hazards in the world s most vulnerable regions-most of them close to the equator and overwhelmingly poor.

Next Friday, a new report from the Intergovernmental Panel on Climate Change, a United Nations body that since 1990 has been assessing global warming, will underline this growing climate divide, according to scientists involved in writing it-with wealthy nations far from the equator not only experiencing fewer effects but also better able to withstand them.

Two thirds of the atmospheric buildup of carbon dioxide, a heat trapping greenhouse gas that can persist in the air for centuries, has come in nearly equal proportions from the United States and Western European countries. Those and other wealthy nations are investing in windmill powered plants that turn seawater to drinking water, in flood barriers and floatable homes, and in grains and soybeans genetically altered to flourish even in a drought.

In contrast, Africa accounts for less than 3 percent of the global emissions of carbon dioxide from fuel burning since 1900, yet its 840 million people face some of the biggest risks from drought and disrupted water supplies, according to new scientific assessments. As the oceans swell with water from melting ice sheets, it is the crowded river deltas in southern Asia and Egypt, along with small island nations, that are most at risk.

Like the sinking of the Titanic, catastrophes are not democratic, said Henry I. Miller, a fellow with the Hoover Institution at Stanford University. A much higher fraction of passengers from the cheaper decks were lost. We ll see the same phenomenon with global warming.

The inequity of this whole situation is really enormous if you look at who s responsible and who s suffering as a result, said Rajendra K. Pachauri, chairman of the United Nations climate panel. In its most recent report, in February, the panel said that decades of warming and rising seas were inevitable with the existing greenhouse gas buildup, no matter what was done about cutting future greenhouse gas emissions.

Many other experts insist this is not an either or situation. They say that cutting the vulnerability of poor regions needs much more attention, but add that unless emissions are curbed, there will be centuries of warming and rising seas that will threaten ecosystems, water supplies, and resources from the poles to the equator, harming rich and poor.

The falling dollar

THE dollar s tumble this week was attended by predictable shrieks from the markets; but as it fell to a 20 month low of $1.32 against the euro, the only real surprise was that it had not slipped sooner. Indeed, there are good reasons to expect its slide to continue, dragging it below the record low of $1.36 against the euro that it hit in December 2004.

The recent decline was triggered by nasty news about the American economy. New figures this week suggested that the housing market s troubles are having a wider impact on the economy. Consumer confidence and durable goods orders both fell more sharply than expected. In contrast, German business confidence has risen to a 15 year high. There are also mounting concerns that central banks in China and elsewhere, which have been piling up dollars assiduously for years, may start selling.

Yet cyclical factors only partly explain why the dollar has been strong. At bottom, its attractiveness is based more on structural factors-or, more accurately, on an illusion about structural differences between the American and European economies.

The main reason for the dollar s strength has been the widespread belief that the American economy vastly outperformed the world s other rich country economies in recent years. But the figures do not support the hype. Sure, America s GDP growth has been faster than Europe s, but that is mostly because its population has grown more quickly too. Dig deeper and the difference shrinks. Official figures of productivity growth, which should in theory be an important factor driving currency movements, exaggerate America s lead. If the two are measured on a comparable basis, productivity growth over the past decade has been almost the same in the euro area as it has in America. Even more important, the latest figures suggest that, whereas productivity growth is now slowing in America, it is accelerating in the euro zone.

So, contrary to popular perceptions, America s economy has not significantly outperformed Europe s in recent years. And to achieve this not much better than parity, America has had to pump itself full of steroids. Since 2000 its structural budget deficit has widened sharply, while American households saving rate has plunged, causing the current account deficit to swell. Over the same period, the euro area economies saw no fiscal stimulus and household saving barely budged.

America s growth, thus, has been driven by consumer spending. That spending, supported by dwindling saving and increased borrowing, is clearly unsustainable; and the consequent economic and financial imbalances must inevitably unwind. As that happens, the country could face a prolonged period of slower growth.

As for Europe, the old continent is hobbled by inflexible product and labour markets. But that, paradoxically, is an advantage: it means the place has a lot of scope for improvement. Some

European countries are beginning to contemplate economic reforms. If they push ahead, their growth could actually speed up over the coming years. Once investors spot this, they are likely to conclude that the euro is a better bet than the dollar.

Can milk make you happy Can fish make you smart

Imagine yourself lying in bed, your mind in turmoil. You toss and turn, but sleep won t come. Maybe a bedtime snack would help. What should you choose If you think first of toaster waffles or popcorn, some experts would say you re on the right track. Foods high in complex carbohydrates-such as cereals, potatoes, pasta, crackers, or rice cakes-make many people relaxed and drowsy.

Missed that one Try again. Suppose the weather s rotten, you forgot your homework, and your best friend s mad at you. What s good medicine when you re feeling low A sugary cola or candy may give you a quick lift, but you ll crash just as quickly. Better choices may be Brazil nuts , skim milk , or a spinach salad . In research studies, all three of those nutrients have been shown to lift spirits and battle the blues.

Try one more. You have a math test coming up in the afternoon. You want to be sharp, but you usually feel sleepy after lunch. Is your best choice an energy fix of fries and a shake or a broiled chicken breast and low fat yogurt If you pick the high fat fries and shake, you may feel sluggish and blow that test. The protein rich chicken and yogurt are better choices. Protein foods energize, some experts say.

How does food affect mood and mind The answer may lie in the chemistry of the brain and nervous system. Molecules called neurotransmitters are chemical messengers. They carry a nerve impulse across the gap between nerve cells. The release of neurotransmitter molecules from one neuron and their attachment to receptor sites on another keep a nerve impulse moving.

Nerve impulses carry messages from the environment to the brain, for example, the pain you feel when you stub your toe. They also carry messages in the other direction, from the brain to the muscles. That s why you back away from the obstacle that initiated the pain signal and exclaim, Ouch!

Many neurotransmitters are built from the foods we eat, says neuroscientist Eric Chudler of the University of Washington. Too little or too much of a particular nutrient in the diet can affect their production, Chudler says. For example, tryptophan from foods such as yogurt, milk, bananas, and eggs is required for the production of the neurotransmitter serotonin. Phenylalanine from beets, almonds, eggs, meat, and grains goes into making the neurotransmitter dopamine.

Dozens of neurotransmitters are known; hundreds may exist. Their effects depend on their

amounts and where they work in the brain. The neurotransmitter serotonin, for example, is thought to produce feelings of calmness, relaxation, and contentment. Drugs that prevent its reuptake are prescribed to treat depression. In at least some healthy, nondepressed people, carbohydrate foods seem to enhance serotonin production and produce similar effects. It is the balance between different neurotransmitters that helps regulate mood, Chudler says.

Proper nutrition may also enhance brainpower. Choline is a substance similar to the B vitamins. It s found in egg yolks, whole wheat, peanuts, milk, green peas, liver, beans, seafood, and soybeans. The brain uses it to make the neurotransmitter acetylcholine. To test the effects of choline on memory and learning, researchers at the Massachusetts Institute of Technology gave memory tests to college students before increasing the amount of choline in their subjects diets. Later, they retested. On the average, memories were better, and the students learned a list of unrelated words more easily.

2018年可锐考研英语阅读真题范文（七） Don’t shoot the messenger They poison the mind and corrupt the morals of the young, who waste their time sitting on sofas immersed in dangerous fantasy worlds. That, at least, was the charge levelled against novels during the 18th century by critics worried about the impact of a new medium on young people. Today the idea that novels can harm people sounds daft. And that is surely how history will judge modern criticism of video games, which are accused of turning young people into violent criminals. This week European justice ministers met to discuss how best to restrict the sale of violent games to children. Some countries, such as Germany, believe the answer is to ban some games altogether. That is going too far. Criticism of games is merely the latest example of a tendency to demonise new and unfamiliar forms of entertainment. In 1816 waltzing was condemned as a fatal contagion that encouraged promiscuity; in 1910 films were denounced as an evil pure and simple, destructive of social interchange in the 1950s rock ’n’roll music was said to turn young people into devil worshippers and comic books were accused of turning children into drug addicts and criminals. In each case the pattern is the same: young people adopt a new form of entertainment, older people are spooked by its unfamiliarity and condemn it, but eventually the young grow up and the new medium becomes accepted-at which point another example appears and the cycle begins again. The opposition to video games is founded on the mistaken belief that most gamers are children. In fact, twothirds of gamers are over 18 and the average gamer is around 30. But the assumption that gamers are mostly children leads to a double standard. Violent films are permitted and the notion that some films are unsuitable for children is generally understood. Yet different rules are applied to games. Aren’t games different because they are interactive? It is true that video games can make people feel excited or aggressive, but so do many sports. There is no evidence that videogaming causes longterm aggression. Games ought to be agerated, just as films are, and retailers should not sell adultrated games to children any more than they should sell them adultrated films. Ratings schemes are already in place, and in some countries restrictions on the sale of adultrated games to minors have the force of law. Oddly enough, Hillary Clinton, one of the politicians who has led the criticism of the gaming industry in America, has recently come round to this view. Last month she emphasised the need for parents to pay more attention to game ratings and called on the industry, retailers and parents to work together. But this week some European politicians seemed to be moving in the other direction: the Netherlands may follow Germany, for example, in banning some games outright. Not all adults wish to play violent games, just as not all of them enjoy violent movies. But they should be free to do so if they wish. 二． Doughnut adjust your set HAVE you ever seen anything on television that made you shout or shake your fist in anger at the screen?

2017考研英语一阅读答案 答案：21-25 ACDDC 21. 答案【A】explain American’s tolerance of current security checks. 解析：本题目为例证题，考察论点与论据。根据题干关键词the crash of Egypt Air Flight 804定位到第二段第二句。例证题中的例子为论据，所要找的答案为论点，而论点在论据之 前，因此该题目的答案是第二段的第一句话。二段首句说的是美国人愿意忍受长时间的安全 检查。正确答案A的American’s tolerance是原文Americans are willing to tolerate的原词复现，current security checks是原文的time-consuming security 的同义转化。干扰项B 的urgency to strengthen security worldwide，原文未提及worldwide，属于扩大范围;选项C的major U.S. major airports属于具体信息的干扰;选项D的privacy 隐私并未提及，是常识性干扰。 22. 答案【C】An increase in the number of travelers. 解析：本题目为原因细节题。根据题干中的long waits at major airports定位到原文第三段的第二句，原文的resulted in 与题干中的contributed to是同义转化，所以定位内容就 是提升的安全措施以及航空旅游的增加。正确答案C的an increase in the number of travelers 是原文 a rise in airline travel的同义替换。干扰项A的carry-on bags是在第四段的最后一句出现的，非定位句内容;选项B的TSA efficiency也出现在第四段;选项D的unexpected secret checks未提及。

2015年考研英语二阅读Text1真题详解

2015年考研英语二阅读Text1真题详解 整篇文章的主题是与我们生活息息相关的内容，文章的难度不大，相比2014年英语二的阅读来说，难度稳定，这是在我们预料之中的。 第21题According to Paragraph 1,most previous surveys found that home＿＿＿(根据第一段可知，之前的调查中认为家是一个____地方)。[A] offered greater relaxation than the workplace [B] was an ideal place for stress measurement [C] generated more stress than the workplace [D] was an unrealistic place for relaxation题目中明确给出范围，所以我们只要在第一段中找答案，且要注意题目中的关键词是previous。回归第一段，不难发现文章的首句便是答案出处：A new study suggests that contrary to most surveys, people are actually more stressed at home than at work.（新的研究显示不同于以往的绝大多数调查，人们在家比工作时的压力更大）。这句话中new、contrary to most surveys是提示词，与题目中的previous study相对应的，不难做出正确答案是[A] 第22题According to Damaske, who are likely to be the happiest at home?（Damaske 认为，谁可能是最家里最快乐的？）读完题目，回到文章第二段找Damaske的观点：It is men, not women, who report being happier at home than at work.在家男性比女性更快乐，Another surprise is that findings hold true for both those with children and without, but more so for nonparents.这句话的关键词是more,它与题目中的happiest最高级是相对应的，所以解这道题的关键便是nonparents.但是对于很多同学来说，nonparents是个生词，不认识。其实大家只要上过中公考研的英语词汇课，学习过词根词缀法，这个单词就变的很简单。nonparents是由否定前缀non-+parents构成的，non-这个否定前缀表示“不无非”，所以整个单词可以译为不是父母。四个选项[A] Childless wives [B] Working mothers [C] Childless husbands [D] Working fathers，我们可以轻易选出答案C，没有孩子且是丈夫。 第23题，The blurring of working women's roles refers to the fact that＿＿。回归第三段中，找到With the blurring of roles，发现前面的句子正是对这种现象的解释：for women who work outside the home, they often are playing catch-up-with-household tasks.以及后面的the home front lags well behind the workplace a making adjustments for working women，指的便是女性不仅得工作赚钱，而且还得在家得忙家务，所以她们的身份是双重的。所以选[D] they are both bread winners and housewives. 第24题，The word“ moola”(Line4,Para4)most probably means＿＿这是一道词义推测题，它与前文中的marking money是近义词，答案选[C] earnings收入。 第25题The home front differs from the workplace in that＿＿。文章第5段there are inadequate rewards for most of them. Your home colleagues-your family-have no clear rewards for their labor;家务劳动不会像工作一样得到足够的奖励，而且分工也是不明确的。答案对应选项[A] division of labor at home is seldom clear-cut. 虽然有突破口、也有规律可循，但这并不意味着我们可以一劳永逸、高枕无忧，要知道，

2018考研英语阅读理解模拟试题及参考答案

2018考研英语阅读理解模拟试题及参考答案 Text 1 Against a backdrop of drastic changes in economy and population structure, younger Americans are drawing a new 21st-century road map to success, a latest poll has found. Across generational lines, Americans continue to prize many of the same traditional milestones of a successful life, including getting married, having children, owning a home, and retiring in their sixties. But while young and old mostly agree on what constitutes the finish line of a fulfilling life, they offer strikingly different paths for reaching it. Young people who are still getting started in life were more likely than older adults to prioritize personal fulfillment in their work, to believe they will advance their careers most by regularly changing jobs, to favor communities with more public services and a faster pace of life, to agree that couples should be financially secure before getting married or having children, and to maintain that children are best served by two parents working outside the home, the survey found. From career to community and family, these contrasts suggest that in the aftermath of the searing Great Recession, those just starting out in life are defining priorities and expectations that will increasingly spread through virtually all aspects of American life, from consumer preferences to housing patterns to politics. Young and old converge on one key point: Overwhelming majorities of both groups said they believe it is harder for young people today to get started in life than it was for earlier generations. While younger people are somewhat more optimistic than their elders about the prospects for those starting out today, big majorities in both groups believe those “just getting started in life” face a tougher a good-paying job, starting a family, managing debt, and finding affordable housing. Pete Schneider considers the climb tougher today. Schneider, a 27-yaear-old auto technician from the Chicago suburbs says he struggled to find a job after graduating from college. Even now that he is working steadily, he said.” I can’t afford to pay ma monthly mortgage payments on my own, so I have to rent rooms out to people to mark that happen.” Looking back, he is str uck that his parents could provide a comfortable life for their?children even though neither had completed college when he was young. “I still grew up in an upper middle-class home with parents who didn’t have college degrees,” Schneider said. “I don’t think people are capable of that anymore.” 1. One cross-generation mark of a successful life is_____.? [A] trying out different lifestyles [B] having a family with children [C] working beyond retirement age [D] setting up a profitable business 答案：C 2. It can be learned from Paragraph 3 that young people tend to?____.

Mark your answers on the ANSWER SHEET. （40 points） Text 1 A new study suggests that contrary to most surveys. People art actually more stressed at home than at work. Researchers measured people's cortisol ， which is it at stress marker， while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge. “Further contradicting conventional wisdom， we found that women as well as men have lower levels of stress at work than at home，” writes one of the researchers. Sarah Damaske， In fact women say they feel better at work. She notes. “it is men not women. Who report being happier at home than at work，” Another surprise is that the findings hold true for both those with children without， but more so for nonparents. This is why people who work outside the home have better health. What the study doesn't measure is whether people are still doing work when they' re at home， whether it is household work or work brought home from the office. For many men， the end of the workday is a time to kick back. For women who stay home，they never get to leave the office. And for women who work outside the home， they often are playing catch-up-with-household tasks. With the blurring of roles， and the fact that the home front lags well behind the workplace in making adjustments for working women， it' s not surprising that women are more stressed at home. But it's not just a gender thing. At work， people pretty much know what they're supposed to be doing： working， making money， doing the tasks they have to do in order to draw an income. The bargain is very pure： Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola. On the home front， however， people have no such clarity. Rare is the household in which the division of labor is so clinically and methodically laid out. There are a lot of tasks to be done， there are inadequate rewards for most of them.
