Đề Cambridge IELTS 14 Test 2 - passage 2:
BACK TO THE FUTURE OF SKYSCRAPER DESIGN
Answers to the problem of excessive electricity use by skyscrapers and large public buildings can be found in ingenious but forgotten architectural designs of the 19th and early-20th centuries
A. The Recovery of Natural Environments in Architecture by Professor Alan Short is the culmination of 30 years of research and award-winning green building design by Short and colleagues in Architecture, Engineering, Applied Maths and Earth Sciences at the University of Cambridge.
'The crisis in building design is already here,' said Short. 'Policy makers think you can solve energy and building problems with gadgets. You can't. As global temperatures continue to rise, we are going to continue to squander more and more energy on keeping our buildings mechanically cool until we have run out of capacity.'
B. Short is calling for a sweeping reinvention of how skyscrapers and major public buildings are designed - to end the reliance on sealed buildings which exist solely via the 'life support' system of vast air conditioning units.
Instead, he shows it is entirely possible to accommodate natural ventilation and cooling in large buildings by looking into the past, before the widespread introduction of air conditioning systems, which were 'relentlessly and aggressively marketed' by their inventors.
C. Short points out that to make most contemporary buildings habitable, they have to be sealed and air conditioned. The energy use and carbon emissions this generates is spectacular and largely unnecessary. Buildings in the West account for 40-50% of electricity usage, generating substantial carbon emissions, and the rest of the world is catching up at a frightening rate. Short regards glass, steel and air-conditioned skyscrapers as symbols of status, rather than practical ways of meeting our requirements.
D. Short's book highlights a developing and sophisticated art and science of ventilating buildings through the 19th and earlier-20th centuries, including the design of ingeniously ventilated hospitals. Of particular interest were those built to the designs of John Shaw Billings, including the first Johns Hopkins Hospital in the US city of Baltimore (1873-1889).
'We spent three years digitally modelling Billings' final designs,' says Short. 'We put pathogens• in the airstreams, modelled for someone with tuberculosis (TB) coughing in the wards and we found the ventilation systems in the room would have kept other patients safe from harm.
E. 'We discovered that 19th-century hospital wards could generate up to 24 air changes an hour-that's similar to the performance of a modern-day, computer-controlled operating theatre. We believe you could build wards based on these principles now.
Single rooms are not appropriate for all patients. Communal wards appropriate for certain patients - older people with dementia, for example - would work just as well in today's hospitals, at a fraction of the energy cost.'
Professor Short contends the mindset and skill-sets behind these designs have been completely lost, lamenting the disappearance of expertly designed theatres, opera houses, and other buildings where up to half the volume of the building was given over to ensuring everyone got fresh air.
F. Much of the ingenuity present in 19th-century hospital and building design was driven by a panicked public clamouring for buildings that could protect against what was thought to be the lethal threat of miasmas - toxic air that spread disease. Miasmas were feared as the principal agents of disease and epidemics for centuries, and were used to explain the spread of infection from the Middle Ages right through to the cholera outbreaks in London and Paris during the 1850s. Foul air, rather than germs, was believed to be the main driver of 'hospital fever', leading to disease and frequent death. The prosperous steered clear of hospitals.
While miasma theory has been long since disproved, Short has for the last 30 years advocated a return to some of the building design principles produced in its wake.
G. Today, huge amounts of a building's space and construction cost are given over to air conditioning. 'But I have designed and built a series of buildings over the past three decades which have tried to reinvent some of these ideas and then measure what happens. 'To go forward into our new low-energy, low-carbon future, we would be well advised to look back at design before our high-energy, high-carbon present appeared. What is surprising is what a rich legacy we have abandoned.'
H. Successful examples of Short's approach include the Queen's Building at De Montfort University in Leicester. Containing as many as 2,000 staff and students, the entire building is naturally ventilated, passively cooled and naturally lit, including the two largest auditoria, each seating more than 150 people. The award-winning building uses a fraction of the electricity of comparable buildings in the UK.
Short contends that glass skyscrapers in London and around the world will become a liability over the next 20 or 30 years if climate modelling predictions and energy price rises come to pass as expected.
I. He is convinced that sufficiently cooled skyscrapers using the natural environment can be produced in almost any climate. He and his team have worked on hybrid buildings in the harsh climates of Beijing and Chicago - built with natural ventilation assisted by back-up air conditioning - which, surprisingly perhaps, can be switched off more than half the time on milder days and during the spring and autumn.
“My book is a recipe book which looks at the past, how we got to where we are now, and how we might reimagine the cities, offices and homes of the future. There are compelling reasons to do this. The Department of Health says new hospitals should be naturally ventilated, but they are not. Maybe it’s time we changed our outlook.”

根據計算,100萬人遊行隊伍要從維多利亞公園排到廣東;200萬人遊行則要排到泰國。
順道一提香港15~30歲人口約莫100出頭萬人。以照片人群幾乎都是此年齡帶來看,兩個數字都是明顯誇大太多了。
另一個可以參考的是1969年的Woodstock Music & Art Fair,幾天內湧進40萬人次,照片看起來也是滿山滿谷的人。(http://sites.psu.edu/…/upl…/sites/851/2013/01/Woodstock3.jpg)
當年40萬人次引發驚人的大塞車,幾乎花十幾個小時才逐漸清場。
而香港遊行清場速度明顯快得多。
順道一提,因此運動而認定「你的父母不愛你」的白痴論述也如同文化大革命時的「爹親娘親不如毛主席親」般開始出現:

EVERY MAJOR NEWS outlet in the world is reporting that two million people, well over a quarter of our population, joined a single protest.
.
It’s an astonishing thought that filled an enthusiastic old marcher like me with pride. Unfortunately, it’s almost certainly not true.
.
A march of two million people would fill a street that was 58 kilometers long, starting at Victoria Park in Hong Kong and ending in Tanglangshan Country Park in Guangdong, according to one standard crowd estimation technique.
.
If the two million of us stood in a queue, we’d stretch 914 kilometers (568 miles), from Victoria Park to Thailand. Even if all of us marched in a regiment 25 people abreast, our troop would stretch towards the Chinese border.
.
Yes, there was a very large number of us there. But getting key facts wrong helps nobody. Indeed, it could hurt the protesters more than anyone.
.
For math geeks only, here’s a discussion of the actual numbers that I hope will interest you whatever your political views.
.
.
DO NUMBERS MATTER?
.
People have repeatedly asked me to find out “the real number” of people at the recent mass rallies in Hong Kong.
.
I declined for an obvious reason: There was a huge number of us. What does it matter whether it was hundreds of thousands or a million? That’s not important.
.
But my critics pointed out that the word “million” is right at the top of almost every report about the marches. Clearly it IS important.
.
.
FIRST, THE SCIENCE
.
In the west, drone photography is analyzed to estimate crowd sizes.
.
This reporter apologizes for not having found a comprehensive database of drone images of the Hong Kong protests.
.
But we can still use related methods, such as density checks, crowd-flow data and impact assessments. Universities which have gathered Hong Kong protest march data using scientific methods include Hong Kong Polytechnic University, Hong Kong University of Science and Technology, University of Hong Kong, and Hong Kong Baptist University.
.
.
DENSITY CHECKS
.
Figures gathered in the past by Hong Kong Polytechnic specialists using satellite photo analysis found a density level of one square meter per marcher. Modern analysis suggests this remains roughly accurate.
.
I know from experience that Hong Kong marches feature long periods of normal spacing (one square meter or one and half per person, walking) and shorter periods of tight spacing (half a square meter or less per person, mostly standing).
.
.
JOINERS AND SPEED
.
We need to include people who join halfway. In the past, a Hong Kong University analysis using visual counting methods cross-referenced with one-on-one interviews indicated that estimates should be boosted by 12% to accurately reflect late joiners. These days, we’re much more generous in estimating joiners.
.
As for speed, a Hong Kong Baptist University survey once found a passing rate of 4,000 marchers every ten minutes.
.
Videos of the recent rallies indicates that joiner numbers and stop-start progress were highly erratic and difficult to calculate with any degree of certainty.
.
.
DISTANCE MULTIPLIED BY DENSITY
.
But scientists have other tools. We know the walking distance between Victoria Park and Tamar Park is 2.9 kilometers. Although there was overspill, the bulk of the marchers went along Hennessy Road in Wan Chai, which is about 25 meters (or 82 feet) wide, and similar connected roads, some wider, some narrower.
.
Steve Doig, a specialist in crowd analysis approached by the Columbia Journalism Review (CJR), analyzed an image of Hong Kong marchers to find a density level of 7,000 people in a 210-meter space. Although he emphasizes that crowd estimates are never an exact science, that figure means one million Hong Kong marchers would need a street 18.6 miles long – which is 29 kilometers.
.
Extrapolating these figures for the June 16 claim of two million marchers, you’d need a street 58 kilometers long.
.
Could this problem be explained away by the turnover rate of Hong Kong marchers, which likely allowed the main (three kilometer) route to be filled more than once?
.
The answer is yes, to some extent. But the crowd would have to be moving very fast to refill the space a great many times over in a single afternoon and evening. It wasn’t. While I can walk the distance from Victoria Park to Tamar in 41 minutes on a quiet holiday afternoon, doing the same thing during a march takes many hours.
.
More believable: There was a huge number of us, but not a million, and certainly not two million.
.
.
IMPACT MEASUREMENTS
.
A second, parallel way of analyzing the size of the crowd is to seek evidence of the effects of the marchers’ absence from their normal roles in society.
.
If we extract two million people out of a population of 7.4 million, many basic services would be severely affected while many others would grind to a complete halt.
.
Manpower-intensive sectors of society, such as transport, would be badly affected by mass absenteeism. Industries which do their main business on the weekends, such as retail, restaurants, hotels, tourism, coffee shops and so on would be hard hit. Round-the-clock operations such as hospitals and emergency services would be severely troubled, as would under-the-radar jobs such as infrastructure and utility maintenance.
.
There seems to be no evidence that any of that happened in Hong Kong.
.
.
HOW DID WE GET INTO THIS MESS?
.
To understand that, a bit of historical context is necessary.
.
In 2003, a very large number of us walked from Victoria Park to Central. The next day, newspapers gave several estimates of crowd size.
.
The differences were small. Academics said it was 350,000 plus. The police counted 466,000. The organizers, a group called the Civil Rights Front, rounded it up to 500,000.
.
No controversy there. But there was trouble ahead.
.
.
THINGS FALL APART
.
At a repeat march the following year, it was obvious to all of us that our numbers were far lower that the previous year. The people counting agreed: the academics said 194,000 and the police said 200,000.
.
But the Civil Rights Front insisted that there were MORE than the previous year’s march: 530,000 people.
.
The organizers lost credibility even with us, their own supporters. To this day, we all quote the 2003 figure as the high point of that period, ignoring their 2004 invention.
.
.
THE TRUTH COUNTS
.
The organizers had embarrassed the marchers. The following year several organizations decided to serve us better, with detailed, scientific counts.
.
After the 2005 march, the academics said the headcount was between 60,000 and 80,000 and the police said 63,000. Separate accounts by other independent groups agreed that it was below 100,000.
.
But the organizers? The Civil Rights Front came out with the awkward claim that it was a quarter of a million. Ouch. (This data is easily confirmed from multiple sources in newspaper archives.)
.
.
AN UNEXPECTED TWIST
.
But then came a twist. Some in the Western media chose to present ONLY the organizer’s “outlier” claim.
.
“Dressed in black and chanting ‘one man, one vote’, a quarter of a million people marched through Hong Kong yesterday,” said the Times of London in 2005.
.
“A quarter of a million protesters marched through Hong Kong yesterday to demand full democracy from their rulers in Beijing,” reported the UK Independent.
.
It became obvious that international media outlets were committed to emphasizing whichever claim made the Hong Kong government (and by extension, China) look as bad as possible. Accuracy was nowhere in the equation.
.
.
STRATEGICALLY CHOSEN
.
At universities in Hong Kong, there were passionate discussions about the apparent decision to pump up the numbers as a strategy, with the international media in mind. Activists saw two likely positive outcomes.
.
First, anyone who actually wanted the truth would choose a middle point as the “real” number: thus it was worth making the organizers’ number as high as possible. (The police could be presented as corrupt puppets of Beijing.)
.
Second, international reporters always favored the largest number, since it implicitly criticized China. Once the inflated figure was established in the Western media, it would become the generally accepted figure in all publications.
.
Both of the activists’ predictions turned out to be bang on target. In the following years, headcounts by social scientists and police were close or even impressively confirmed the other—but were ignored by the agenda-driven international media, who usually printed only the organizers’ claims.
.
.
SKIP THIS SECTION
.
Skip this section unless you want additional examples to reinforce the point.
.
In 2011, researchers and police said that between 63,000 and 95,000 of us marched. Our delightfully imaginative organizers multiplied by four to claim there were 400,000 of us.
.
In 2012, researchers and police produced headcounts similar to the previous year: between 66,000 and 97,000. But the organizers claimed that it was 430,000. (These data can also be easily confirmed in any newspaper archive.)
.
.
SKIP THIS SECTION TOO
.
Unless you’re interested in the police angle. Why are police figures seen as lower than others? On reviewing data, two points emerge.
.
First, police estimates rise and fall with those of independent researchers, suggesting that they function correctly: they are not invented. Many are slightly lower, but some match closely and others are slightly higher. This suggests that the police simply have a different counting method.
.
Second, police sources explain that live estimates of attendance are used for “effective deployment” of staff. The number of police assigned to work on the scene is a direct reflection of the number of marchers counted. Thus officers have strong motivation to avoid deliberately under-estimating numbers.
.
.
RECENT MASS RALLIES
.
Now back to the present: this hot, uncomfortable summer.
.
Academics put the 2019 June 9 rally at 199,500, and police at 240,000. Some people said the numbers should be raised or even doubled to reflect late joiners or people walking on parallel roads. Taking the most generous view, this gave us total estimates of 400,000 to 480,000.
.
But the organizers, God bless them, claimed that 1.03 million marched: this was four times the researchers’ conservative view and more than double the generous view.
.
The addition of the “.03m” caused a bit of mirth among social scientists. Even an academic writing in the rabidly pro-activist Hong Kong Free Press struggled to accept it. “Undoubtedly, the anti-amendment group added the extra .03 onto the exact one million figure in order to give their estimate a veneer of accuracy,” wrote Paul Stapleton.
.
.
MIND-BOGGLING ESTIMATE
.
But the vast majority of international media and social media printed ONLY the organizers’ eyebrow-raising claim of a million plus—and their version soon fed back into the system and because the “accepted” number. (Some mentioned other estimates in early reports and then dropped them.)
.
The same process was repeated for the following Sunday, June 16, when the organizers’ frankly unbelievable claim of “about two million” was taken as gospel in the majority of international media.
.
“Two million people in Hong Kong protest China's growing influence,” reported Fox News.
.
“A record two million people – over a quarter of the city’s population” joined the protest, said the Guardian this morning.
.
“Hong Kong leader apologizes as TWO MILLION take to the streets,” said the Sun newspaper in the UK.
.
Friends, colleagues, fellow journalists—what happened to fact-checking? What happened to healthy skepticism? What happened to attempts at balance?
.
.
CONCLUSIONS?
.
I offer none. I prefer that you do your own research and draw your own conclusions. This is just a rough overview of the scientific and historical data by a single old-school citizen-journalist working in a university coffee shop.
.
I may well have made errors on individual data points, although the overall message, I hope, is clear.
.
Hong Kong people like to march.
.
We deserve better data.
.
We need better journalism. Easily debunked claims like “more than a quarter of the population hit the streets” help nobody.
.
International media, your hostile agendas are showing. Raise your game.
.
Organizers, stop working against the scientists and start working with them.
.
Hong Kong people value truth.
.
We’re not stupid. (And we’re not scared of math!)

CAN YOU GET PERVERTED ANIME NOSEBLEEDS? (ANIME VS REALITY)
Nosebleeds from sexual arousal...
We’ve all seen those anime scenes where a guy catches a glimpse of a girl undressing, maybe she’s in a revealing outfit, or acting seductive to the guy. She could be flat out naked. And then suddenly blood shoots out of his nose!
A very iconic scene in Japanese anime and manga. Frequently used as a metaphor for sexual arousal. The nosebleeds can range from just a trickle, to full on fountain gushing. And in some cases, it even serves as a plot device, such as in Dragon Ball with Master Roshi.
Some say, it’s meant to be a powerful way to show the immediate change a person goes though when sexual arousal is induced. Others say it’s really more about the nervousness.
Then there’s the most obvious, an imagery for blood flow to the guy’s nether regions. And taking that one step further, the explosive, projectile nature of the nosebleed is said to be like an ejaculation!
There’s also the idea that the reason for the nosebleed metaphor is because you can’t show a boner in anime. So they had to get creative. Also one doesn’t even need to be capable of a boner to have pervy nosebleeds as some female anime characters also demonstrate this bloody trait.
Ok so, is this real? Does this happen to people in real life?
Shocking as it may be, it doesn’t seem to be backed by medical science. This probably only happens in the anime and manga world, although there are a few real life examples of this happening, but surely it’s just coincidence? Otherwise all late middle schools and high schools would be like a scene from Saw!
But how did pervy nose bleeds become a thing in Japan?
It’s actually existed for a while now. Manga artist Yasuji Tanioka is believed to be the first person to have introduced this nosebleed motif with his early 1970’s manga (Yasuji no Mettameta Gaki Dou Kouza). Subsequently, other Japanese artists liked the expression and began replicating it in their own works. And, we pretty much know where it went from there.
A bit of anime history to end things there.
