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.”

今早為Asian Medical Students Association Hong Kong (AMSAHK)的新一屆執行委員會就職典禮作致詞分享嘉賓,題目為「疫情中的健康不公平」。
感謝他們的熱情款待以及為整段致詞拍了影片。以下我附上致詞的英文原稿:
It's been my honor to be invited to give the closing remarks for the Inauguration Ceremony for the incoming executive committee of the Asian Medical Students' Association Hong Kong (AMSAHK) this morning. A video has been taken for the remarks I made regarding health inequalities during the COVID-19 pandemic (big thanks to the student who withstood the soreness of her arm for holding the camera up for 15 minutes straight), and here's the transcript of the main body of the speech that goes with this video:
//The coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus, continues to be rampant around the world since early 2020, resulting in more than 55 million cases and 1.3 million deaths worldwide as of today. (So no! It’s not a hoax for those conspiracy theorists out there!) A higher rate of incidence and deaths, as well as worse health-related quality of life have been widely observed in the socially disadvantaged groups, including people of lower socioeconomic position, older persons, migrants, ethnic minority and communities of color, etc. While epidemiologists and scientists around the world are dedicated in gathering scientific evidence on the specific causes and determinants of the health inequalities observed in different countries and regions, we can apply the Social Determinants of Health Conceptual Framework developed by the World Health Organization team led by the eminent Prof Sir Michael Marmot, world’s leading social epidemiologist, to understand and delineate these social determinants of health inequalities related to the COVID-19 pandemic.
According to this framework, social determinants of health can be largely categorized into two types – 1) the lower stream, intermediary determinants, and 2) the upper stream, structural and macro-environmental determinants. For the COVID-19 pandemic, we realized that the lower stream factors may include material circumstances, such as people’s living and working conditions. For instance, the nature of the occupations of these people of lower socioeconomic position tends to require them to travel outside to work, i.e., they cannot work from home, which is a luxury for people who can afford to do it. This lack of choice in the location of occupation may expose them to greater risk of infection through more transportation and interactions with strangers. We have also seen infection clusters among crowded places like elderly homes, public housing estates, and boarding houses for foreign domestic helpers. Moreover, these socially disadvantaged people tend to have lower financial and social capital – it can be observed that they were more likely to be deprived of personal protective equipment like face masks and hand sanitizers, especially during the earlier days of the pandemic. On the other hand, the upper stream, structural determinants of health may include policies related to public health, education, macroeconomics, social protection and welfare, as well as our governance… and last, but not least, our culture and values. If the socioeconomic and political contexts are not favorable to the socially disadvantaged, their health and well-being will be disproportionately affected by the pandemic. Therefore, if we, as a society, espouse to address and reduce the problem of health inequalities, social determinants of health cannot be overlooked in devising and designing any public health-related strategies, measures and policies.
Although a higher rate of incidence and deaths have been widely observed in the socially disadvantaged groups, especially in countries with severe COVID-19 outbreaks, this phenomenon seems to be less discussed and less covered by media in Hong Kong, where the disease incidence is relatively low when compared with other countries around the world. Before the resurgence of local cases in early July, local spread of COVID-19 was sporadic and most cases were imported. In the earlier days of the pandemic, most cases were primarily imported by travelers and return-students studying overseas, leading to a minor surge between mid-March and mid-April of 874 new cases. Most of these cases during Spring were people who could afford to travel and study abroad, and thus tended to be more well-off. Therefore, some would say the expected social gradient in health impact did not seem to exist in Hong Kong, but may I remind you that, it is only the case when we focus on COVID-19-specific incidence and mortality alone. But can we really deduce from this that COVID-19-related health inequality does not exist in Hong Kong? According to the Social Determinants of Health Framework mentioned earlier, the obvious answer is “No, of course not.” And here’s why…
In addition to the direct disease burden, the COVID-19 outbreak and its associated containment measures (such as economic lockdown, mandatory social distancing, and change of work arrangements) could have unequal wider socioeconomic impacts on the general population, especially in regions with pervasive existing social inequalities. Given the limited resources and capacity of the socioeconomically disadvantaged to respond to emergency and adverse events, their general health and well-being are likely to be unduly and inordinately affected by the abrupt changes in their daily economic and social conditions, like job loss and insecurity, brought about by the COVID-19 outbreak and the corresponding containment and mitigation measures of which the main purpose was supposedly disease prevention and health protection at the first place. As such, focusing only on COVID-19 incidence or mortality as the outcomes of concern to address health inequalities may leave out important aspects of life that contributes significantly to people’s health. Recently, my research team and I collaborated with Sir Michael Marmot in a Hong Kong study, and found that the poor people in Hong Kong fared worse in every aspects of life than their richer counterparts in terms of economic activity, personal protective equipment, personal hygiene practice, as well as well-being and health after the COVID-19 outbreak. We also found that part of the observed health inequality can be attributed to the pandemic and its related containment measures via people’s concerns over their own and their families’ livelihood and economic activity. In other words, health inequalities were contributed by the pandemic even in a city where incidence is relatively low through other social determinants of health that directly concerned the livelihood and economic activity of the people. So in this study, we confirmed that focusing only on the incident and death cases as the outcomes of concern to address health inequalities is like a story half-told, and would severely truncate and distort the reality.
Truth be told, health inequality does not only appear after the pandemic outbreak of COVID-19, it is a pre-existing condition in countries and regions around the world, including Hong Kong. My research over the years have consistently shown that people in lower socioeconomic position tend to have worse physical and mental health status. Nevertheless, precisely because health inequality is nothing new, there are always voices in our society trying to dismiss the problem, arguing that it is only natural to have wealth inequality in any capitalistic society. However, in reckoning with health inequalities, we need to go beyond just figuring out the disparities or differences in health status between the poor and the rich, and we need to raise an ethically relevant question: are these inequalities, disparities and differences remediable? Can they be fixed? Can we do something about them? If they are remediable, and we can do something about them but we haven’t, then we’d say these inequalities are ultimately unjust and unfair. In other words, a society that prides itself in pursuing justice must, and I say must, strive to address and reduce these unfair health inequalities. Borrowing the words from famed sociologist Judith Butler, “the virus alone does not discriminate,” but “social and economic inequality will make sure that it does.” With COVID-19, we learn that it is not only the individuals who are sick, but our society. And it’s time we do something about it.
Thank you very much!//
Please join me in congratulating the incoming executive committee of AMSAHK and giving them the best wishes for their future endeavor!

Taxing the rich to fund welfare is Nobel winner’s growth mantra
How do you spur ( ) demand in an economy? By raising direct taxes and distributing the money among the poor, says this year’s winner of the Nobel prize for economics.
Reducing taxes to boost ( ) investments is a myth ( ) spread by businesses, says Abhijit Banerjee, who won the prize along with Esther Duflo of the Massachusetts Institute of Technology (MIT) and Michael Kremer of Harvard University for their approach to alleviating ( ) global poverty. “You are giving incentives ( ) to the rich who are already sitting on tons of cash.”
Countries from China to India to Indonesia are slashing ( ) taxes for businesses to spur growth amid a gloomy ( ) outlook ( ) for global economic expansion. The International Monetary Fund last month made a fifth-straight cut to its 2019 global growth forecast, pegging ( ) it at 3 percent.
“You don’t boost growth by cutting taxes, you do that by giving money to people,” Banerjee said in an interview on Oct. 21, suggesting that cash in the hands of the poor will drive consumption ( ). “Investment will respond to demand.”
China earlier this year rolled out ( ) tax cuts worth US$280 billion on personal income and corporate ( ) profits, while India surprised with a US$20 billion stimulus ( ), taking its corporate tax rate to among the lowest in Asia. Indonesia also plans to lower tax on companies to 20 percent from 25 percent.
MIT Professor Banerjee spoke in New Delhi where he was promoting ( ) his book Good Economics for Hard Times.
Last year, US President Donald Trump unveiled ( ) a US$1.5 trillion tax package, and has promised “very substantial ( )” tax cuts in 2020 for “middle-income” Americans.
It’s the widening inequality ( ) in developed countries such as the US that has angered people and is pushing the world into a trade war, Banerjee said. “It is unbelievable that in the name of growth you have allowed inequality to explode to this point.”
India Slowdown
Growth in India, Asia’s third-largest economy, has slumped ( ) to a six-year low as consumption is weak, prompting the central bank to cut interest rates to the lowest in almost a decade.
The government complemented ( ) the monetary policy easing with a series of measures to reverse ( ) the demand slowdown. Those steps — including scrapping ( ) a tax on foreign funds to allowing tax concessions ( ) on vehicle purchases — have raised concerns of a fiscal ( ) slippage ( ).
“Given the demand slump it’s not a bad thing for the government to be expansionary,” Banerjee said. “If we want to stimulate demand and corporate tax cut doesn’t do that, which is my prediction, then what do we do.”
諾貝爾經濟學獎得主:「劫富濟貧」是良方
在經濟結構中要如何刺激需求?今年的諾貝爾經濟學獎得主認為,應提高直接稅,並將錢分配給窮人。
Abhijit Banerjee與麻省理工學院的Esther Duflo及哈佛大學的Michael Kremer,以其對緩解全球貧窮問題的研究,共同獲得了今年的諾貝爾經濟學獎。Banerjee表示,用減稅來鼓勵投資,是企業所散播的迷思,減稅「是在獎勵富人,而這些有錢人已是坐擁金山銀山」。
全球經濟前景黯淡,從中國到印度再到印尼都在大幅削減企業稅,以刺激經濟成長。國際貨幣基金上個月將二○一九年全球成長率連續第五次下修,將其定為百分之三。
Banerjee十月二十一日在接受採訪時表示:「促進經濟成長不是透過減稅來達成,而是要給人錢」。這表示,窮人手中的現金才會推動消費,「有需求才會有投資」。
今年稍早,中國對個人所得和企業利潤實施減稅,所減之稅額達兩千八百億美元。而印度則出乎意料地祭出兩百億美元的經濟刺激措施,將印度的公司稅稅率降至亞洲最低。印尼還計劃將公司稅由百分之二十五降至百分之二十。
麻省理工學院的Banerjee教授在印度新德里宣傳其著作《艱困時期的好經濟學》時,做出以上表示。
美國總統Donald Trump去年公佈了一項一點五兆美元的稅務方案,並承諾在二○二○年對「中等收入」的美國人實施「很實質性的」減稅。
Banerjee說,激怒人們,並讓世界陷入貿易戰的,是美國等已開發國家日益擴大的不平等。「令人難以置信的是,你打著經濟成長的名號,卻讓不平等迅速擴大到這個地步。」
印度經濟成長下滑
由於消費疲弱,印度這亞洲第三大經濟體,其經濟成長已跌至六年來最低,使得印度央行將利率調降至近十年來最低。
為了避免因貨幣政策寬鬆所造成的需求放緩,印度政府以一系列措施來做配套。這些措施─包括取消對外資課稅,以及購車稅率優惠─引起了人們對政府財政惡化的擔憂。
Banerjee表示:「由於需求下滑,因此增加政府支出並不是件壞事」。「如果我們要刺激需求,而削減公司稅又如我所料達不到這目標,那我們也別無他法。」
