One of the key challenges in urban architecture over the next 50 years will be figuring out how to squeeze vast numbers of additional people into urban areas that are already extremely crowded. London, for example, will somehow have to deal with a projected 100,000 extra inhabitants every year until 2016. The current plan of building a new “satellite towns” of the city causes a lot of problems---but architecture think tanks are working on ambitious solutions that go vertical instead of horizontal in search of space.
In terms of population density, London is one of the least crowded major cities in the world---four times fewer people per square kilometer than Paris, for example, six times fewer than New York and eight times fewer than Cairo. But the fact remains that the city’s population is growing at a rapid rate, and horizontal expansion into the surrounding areas is eating up increasingly important agricultural land, as well as worsening all the transport problems that come with urban growth.
Popular Architecture would propose a radically different solution. The proposal is to go upwards, with vertical towers of considerable size, each representing an entire new town, by the time it’s completed. Each tower would be 1500 meters high. Beyond mere accommodation, each tower would function as an entire town unit, with its own schools, hospitals, parks and gardens, sports faculties, business areas and community spaces. The population density of such a tower could help lower the individual energy requirements of each inhabitant, reducing the ecological impact of the population as a whole.
The village towers are considered as hollow tubes, with large holes to allow light and air though the entire construction. Occasional floor discs spread throughout the height of the building will give inhabitants large central areas in the middle of the tube to use as gathering spaces.
While the building itself is unlikely ever to be seriously considered for construction---imagine the number of elevators it would need, let alone the safety implications of open areas at such heights and with such wind exposure---the concept can serve as conversation-starter for urban planners looking to face the challenges of the current and coming countries.
One key challenging task for urban architects in the future is to .
A.build new satellite towns
B.work out ambitious plans
C.design less crowded cities
D.accommodate more inhabitants
Which of the following cities has the largest population density？
A.Cairo.
B.Paris.
C.London.
D.New York.
Horizontal expansion not only wastes land, but makes it hard for London to .
A.handle its safety problems
B.resolve its transport issues
C.control its population growth
D.measure its population density
The vertical tower would represent an entire new town in itself because.
A.it is energy-saving
B.it is cost-effective
C.it is self-sufficient
D.it is comfort-oriented
For city planners today, the idea of building a vertical tower can become.A.a topic for fun
B.a shocking reality
C.a modest proposal
D.a source of inspiration

The celebration of International Women’s Day (IWD) in 2011 was special as it marked the 100th anniversary of IWD. The United Nations’ theme for the 2011 IWD was “Equal access to education, training and science and technology: Pathway to decent work for women”.
One hundred years ago, gender equality and women’s empowerment were largely radical ideas. One hundred years later, there has been significant progress in women’s empowerment and participation through determined advocacy, practical action and enlightened policy making. However, in too many countries and societies, women’s social position is still low and lots of women are still trapped by poverty, discrimination, unemployment, illiteracy and violence.
As a basic human right, education is a key driver of economic growth and social change and the basis of women’s empowerment. The global economy is increasingly knowledge-driven, and requires an educated workforce able to apply the existing technology and to develop new science and technologies to combat poverty and adapt to emerging issues.
As education is the key to greater empowerment for women, investing in women and girls through the education sector has therefore a positive effect on the well-being of their families, their communities and nations. Strengthening the bridges between education, training, science and technology and the labor market is important in order to promote equal opportunity to decent employment for women.
1.2011 International Women’s Day (IWD) was special because().
A.it is the beginning of women’s equality.
B.it is 100th anniversary.
C.women got too much rights in that day
2.（）is a key factor of economic growth and social change and the women’s empowerment.
A.Equality
B.Family responsibility
C.Education
3.Which of the following is not suffered by women in society nowadays().
A.poverty
B.unemployment
C.family burden
4.Which one is NOT mentioned in relation to “education equality”().
A.pathway to decent work for women
B.development of new science
C.women’s empowerment.
5.What is the best title for the passage().
A.Creating Equal Access to Education
B.International Women’s Day
C.Human Rights

4 At an academic conference, a debate took place on the implementation of corporate governance practices in
developing countries. Professor James West from North America argued that one of the key needs for developing
countries was to implement rigorous systems of corporate governance to underpin investor confidence in businesses
in those countries. If they did not, he warned, there would be no lasting economic growth as potential foreign inward
investors would be discouraged from investing.
In reply, Professor Amy Leroi, herself from a developing country, reported that many developing countries are
discussing these issues at governmental level. One issue, she said, was about whether to adopt a rules-based or a
principles-based approach. She pointed to evidence highlighting a reduced number of small and medium sized initial
public offerings in New York compared to significant growth in London. She suggested that this change could be
attributed to the costs of complying with Sarbanes-Oxley in the United States and that over-regulation would be the
last thing that a developing country would need. She concluded that a principles-based approach, such as in the
United Kingdom, was preferable for developing countries.
Professor Leroi drew attention to an important section of the Sarbanes-Oxley Act to illustrate her point. The key
requirement of that section was to externally report on – and have attested (verified) – internal controls. This was, she
argued, far too ambitious for small and medium companies that tended to dominate the economies of developing
countries.
Professor West countered by saying that whilst Sarbanes-Oxley may have had some problems, it remained the case
that it regulated corporate governance in the ‘largest and most successful economy in the world’. He said that rules
will sometimes be hard to follow but that is no reason to abandon them in favour of what he referred to as ‘softer’
approaches.
(a) There are arguments for both rules and principles-based approaches to corporate governance.
Required:
(i) Describe the essential features of a rules-based approach to corporate governance; (3 marks)

A challenge in working in customer service is to ensure that you have focused your attention on the right key areas, measured by the right Key Performance Indicator (KPI). One of the most important aspects of a customer service KPI is what is often referred to as the Feel Good Factor. Basically the goal is not only to help the customer have a good experience, but to offer an experience that exceeds expectations. Several key points are listed as follows:
Know what products/service you are offering from back to front. In other words, be an information expert. It is okay to say I don’t know, but it should always be followed up by but let me find out or possibly but this person will be able to assist you. Whatever the situation may be, make sure that you don’t leave your customer with an unanswered question.
Most of the communication that you relay to others is done through body language. If you have negative body language when you communicate with others, it shows that you don't care. Two of the most important aspects of positive body language are smiling and eye contact. Make sure to look your customers in the eye. It shows that we are listening to them and hearing what they are saying. And of course smiling is more inviting than a blank look or frown.
Nothing surprises your customers more than an employee going the extra mile to help them. Always look for ways to go above and beyond the expectations of your customers. In doing so, it helps them to know that you care and it will leave them with the Feel Good Factor that you are searching for.
1. The goal of customer service is to give customers an experience that meets their expectations.{T; F}
2. Leave your customer with an unanswered question is unacceptable.{T; F}
3. Both positive body language and negative body language are necessary in customer service.{T; F}
4. Eye contact is one of the most important aspects of positive body language.{T; F}
5. The underlined going the extra mile to help them in the last paragraph means going a long way to help them.{T; F}
