雅思阅读7大逻辑关系-判断题中的比较逻辑
在很多烤鸭的眼中，当阅读题干出现比较关系时，就很容易在 FALSE 与 NOT GIVEN 之间傻傻分不清楚。
或者认为，如果答案为TRUE，就一定意味着原文出现比较级或最高级。但事实如此吗?
Of course not.
实际上，在阅读题目当中，比较关系有显性和隐性之分，直接出现比较级的形式只是显性比较关系的体现。
除此之外，还有一些隐性比较关系的情况会出现在题目当中。今天，我们来罗列以下三种情况：动词、数值以及变化。
1. 动词
一般情况下，表示 上升下降 类型的动词也可以表达比较关系。
例：
题目：There are more people than before.
原文：The population is increasing.
这道题目的答案很显然是true。虽然原文并没有直接出现比较级，但是increase这个趋势性的动词体现出了人口一直增长的含义，意味着靠后时间的人口数量一定大于靠前时间的人口数量，比较关系成立。
同样的道理，如果原文表示的是The population is decreasing，而题目信息表示There are fewer people than before，这个对应关系仍然成立。
2. 数值
除了动词的对应之外，出现不同数字的罗列也可以表达比较关系。
例：
题目：A is older than B.
原文：A is 2 years old and B is 3 years old.
这个例子也非常简单，答案是False。
在题干信息中出现了关于年龄大小的比较级，而原文只是出现了两个不同的年龄数字。
但是这个简单数字大小的对比结果对于大家而言都是显而易见的。
3. 变化
在了解了动词和数字所对应的比较情况后，我们再来看一看变化类的词，所体现的比较考点。
例：
题目：The population has changed.
原文：There are more people than before.
这道题目区别于之前的例题，在题干信息中只体现了变化的概念，但是变化性对应到原文当中，可能会出现比较级或是其他比较关系的对应。
比如，在上述例题中，原文中表示现在的人比过去的人多，题目表示人数发生了变化，这类信息对应关系成立，答案为True。
所以总结一下：比较考点是雅思阅读判断题最常见的考点之一，甚至在诸如配对题这样的难题中也十分常见。
很多同学在做题时，会盲目认为比较级是比较关系的唯一体现。
但事实上，除了比较级这种显性的比较关系之外，还有一部分诸如动词、数值对比以及变化性词汇的使用，都有可能对应比较关系。

雅思阅读精读 | When new grows old
When new grows old (1)
————————————
Artists working with technology struggle to stay current
In 1968 the Institute of Contemporary Arts in London held an exhibition called “Cybernetic Serendipity”， Britain’s first show exploring connections between art and new technology.
It was hugely popular and in hindsight, well timed.
It coincided with two crucial developments in the relationship between art and technology: the pop-art movement, which was demolishing boundaries between high art and everyday life，and ARPANET， the computer-to-computer network which would become the internet.
The internet has continued to erode established notions of what qualifies as art,and who can claim to be an artist.
New categories flourish: net.art，new media art， the New Aesthetic， internet art, post-internet art.
Online-only sales and exhibitions are increasingly common, as is art existing solely in digital form，bought and sold through websites such as Electric Objects (on a mission “to put digital art on a wall in every home”).
Successful careers and expensive collections are built using social media, such as Instagram， the image- and video-sharing app that has users posting 80m photographs a day.
“Electronic Superhighway”, a new show at the White chapel Gallery in London,
looks at how artist shave responded to technology and change.
The exhibition, which takes its name from a phrase coined in 1974 by Nam June Paik, a video artist，to describe the potential of telecommunication systems, is arranged in reverse chronological order.
This calls particular attention to how quickly technologies become obsolete，and how art tied to those forms ages with it.

A Canary in the Coal Mine
The Arctic seems to be getting warmer. So what?
A. “Climate change in the Arctic is a reality now!” So insists Robert Corell， an oceanographer with the American Meteorological Society. Wild-eyed proclamations are all too common when it comes to global warming， but in this case his assertion seems well founded.
B. At first sight， the ACIA’s (American Construction Inspectors Association) report’s conclusions are not so surprising. After all， scientists have long suspected that several factors lead to greater temperature swings at the poles than elsewhere on the planet. One is albedo — the posh scientific name for how much sunlight is absorbed by a planet’s surface， and how much is reflected. Most of the Polar Regions are covered in snow and ice， which are much more reflective than soil or ocean. If that snow melts， the exposure of dark earth (which absorbs heat) acts as a feedback loop that accelerates warming. A second factor that makes the poles special is that the atmosphere is thinner there than at the equator， and so less energy is required to warm it up. A third factor is that less solar energy is lost in evaporation at the frigid poles than in the steamy tropics.
C. And yet the language of this week’s report is still eye-catching： “the Arctic is now experiencing some of the most rapid and severe climate change on Earth.” The last authoritative assessment of the topic was done by the UN’s Intergovernmental Panel on Climate Change (IPCC) in 2001. That report made headlines by predicting a rise in sea level of between 10cm (four inches) and 90cm， and a temperature rise of between 1.4°C and 5.8°C over this century. However， its authors did not feel confident in predicting either rapid polar warming or the speedy demise of the Greenland ice sheet. Pointing to evidence gathered since the IPCC report， this week’s report suggests trouble lies ahead.
D. The ACIA reckons that in recent decades average temperatures have increased almost twice as fast in the Arctic as they have in the rest of the world. Skeptics argue that there are places， such as the high latitudes of the Greenland ice sheet and some buoys at sea， where temperatures seem to have fallen. On the other hand， there are also places， such as parts of Alaska， where they have risen far faster than average. Robin Bell， a geophysicist at Columbia University who was not involved in the report’s compilation， believes that such conflicting local trends point to the value of the international， interdisciplinary approach of this week’s report. As he observes， “climate change， like the weather， can be patchy and you can get fooled unless you look at the whole picture.”
E. And there is other evidence of warming to bolster the ACIA’s case. For example， the report documents the widespread melting of glaciers and of sea ice， a trend already making life miserable for the polar bears and seals that depend on that ice. It also notes a shortening of the snow season. The most worrying finding， however， is the evidence — still preliminary — that the Greenland ice sheet may be melting faster than previously thought.
F. That points to one reason the world should pay attention to this week’s report. Like a canary in a coal mine， the hypersensitive Polar Regions may well experience the full force of global warming before the rest of the planet does. However， there is a second and bigger reason to pay attention. An unexpectedly rapid warming of the Arctic could also lead directly to greater climate change elsewhere on the planet.
G. Arctic warming may influence the global climate in several ways. One is that huge amounts of methane， a particularly potent greenhouse gas， are stored in the permafrost of the tundra. Although a thaw would allow forests to invade the tundra， which would tend to ameliorate any global warming that is going on (since trees capture carbon dioxide， the greenhouse gas most talked about in the context of climate change)， a melting of the permafrost might also lead to a lot of trapped methane being released into the atmosphere， more than offsetting the cooling effects of the new forests.
H. Another worry is that Arctic warming will influence ocean circulation in ways that are not fully understood. One link in the chain is the salinity of seawater， which is decreasing in the north Atlantic thanks to an increase in glacial melt waters. “Because fresh water and salt water have different densities， this ‘freshening’ of the ocean could change circulation patterns.” said Dr. Thomson， a British climate expert. “The most celebrated risk is to the mid-Atlantic Conveyor Belt， a current which brings warm water from the tropics to north-western Europe， and which is responsible for that region’s unusually mild winters，” he added. Some of the ACIA’s experts are fretting over evidence of reduced density and salinity in waters near the Arctic that could adversely affect this current.
I. The biggest popular worry， though， is that melting Arctic ice could lead to a dramatic rise in sea level. Here， a few caveats are needed. For a start， much of the ice in the Arctic is floating in the sea already. Archimedes’s principle shows that the melting of this ice will make no immediate difference to the sea’s level， although it would change its albedo. Second， if land ice， such as that covering Greenland， does melt in large quantities， the process will take centuries. And third， although the experts are indeed worried that global warming might cause the oceans to rise， the main way they believe this will happen is by thermal expansion of the water itself.
J. Nevertheless， there is some cause for nervousness. As the ACIA researchers document， there are signs that the massive Greenland ice sheet might be melting more rapidly than was thought a few years ago. Cracks in the sheet appear to be allowing melt water to trickle to its base， explains Michael Oppenheimer， a climatologist at Princeton University who was not one of the report’s authors. That water may act as a lubricant， speeding up the sheet’s movement into the sea. If the entire sheet melted， the sea might rise by 6-7 meters. But when will this kind of disastrous ice disintegration really happen? While acknowledging it this century is still an unlikely outcome， Dr. Oppenheimer argues that the evidence of the past few years suggests it is more likely to happen over the next few centuries if the world does not reduce emissions of greenhouse gases. He worries that an accelerating Arctic warming trend may yet push the ice melt beyond an “irreversible on / off switch”.
K. That is scary stuff， but some scientists remain unimpressed. Patrick Michaels， a climatologist at the University of Virginia， complains about the ACIA’s data selection， which he believes may have produced evidence of “spurious warming”. He also points out， in a new book， that even if Arctic temperatures are rising， that need not lead directly to the ice melting. As he puts it， “Under global warming， Greenland’s ice indeed might grow， especially if the warming occurs mostly in winter. After all， warming the air ten degrees when the temperature is dozens of degrees below freezing is likely to increase snowfall， since warmer air is generally moister and precipitates more water.”
L. Nils-Axel Morner， a Swedish climate expert based at Stockholm University， points out that observed rises in sea levels have not matched the IPCC’s forecasts. Since this week’s report relies on many such IPCC assumptions， he concludes it must be wrong. Others acknowledge that there is a warming trend in the Arctic， but insist that the cause is natural variability and not the burning of fossil fuels. Such folk point to the extraordinarily volatile history of Arctic temperatures. These varied， often suddenly， long before sport-utility vehicles were invented. However， some evidence also shows that the past few millennia have been a period of unusual stability in the Arctic. It is just possible that the current period of warming could tip the delicate Arctic climate system out of balance， and so drag the rest of the planet with it.
M. Not everybody wants to hear a story like that. But what people truly believe is happening can be seen in their actions better than in their words. One of the report’s most confident predictions is that the breakup of Arctic ice will open the region to long-distance shipping and， ironically， to drilling for oil and gas. It is surely no coincidence， then， that the Danish government， which controls Greenland， has just declared its intention to claim the mineral rights under the North Pole. It， at least， clearly believes that the Arctic ocean may soon be ice-free.
