TEXT 2
I do realize that in the world of technology there are early and late adopters. I’m not the earliest of cutting-edge early TESL adopters, but I do like to try out new technology and incorporate it into my teaching. This list is a handful of technologies that are established enough not to be too problematic, user-friendly enough that just about anyone can start using them quickly, and useful enough that you’ll soon wonder how you got along without them. In short, this is a list of tech that just about everyone can (and maybe even should) be using in 2010.
1. Wikipedia – It has become popular to question its accuracy. Wikipedia has become a real knowledge bank on the internet. Once we figure out what it is (a compilation of all referenced knowledge) many of these criticisms fall down. Access to all this information means a reorganization of learning.
2. Google – No, I don’t just mean search, but all the other stuff: maps, docs, calendar, etc. It’s never been so easy to collaborate with other people.
3. Twitter – A year ago, I taught a course through Twitter with mixed results. This microblog is almost exclusively interactive, but my ESL students found it tough to collaborate within Twitter because of its constraints on length. The email by contrast, is very simple – it is equally interactive but it is constraint free. So, you should use it and you should see interesting results !
Can you learn the language by using the above alone? Of course not! But they are a good springboard and I hope they lead you to discover all other media available out there (ebooks, blogs, YouTube videos, music, movies, etc.).
More web in the pipeline. Please post a comment.
In the excerpt “'Hobson-Jobson: The Definitive Glossary of British India' was published in 1886" (l. 7 and 8), “was published" can be correctly replaced by has been published.
What causes hunger?
The world produces enough to feed the entire global population of 7 billion people. And yet, one person in eight on the planet goes to bed hungry each night. In some countries, one child in three is underweight. Why does hunger exist? There are many reasons for the presence of hunger in the world and they are often interconnected. Here are six that we think are important.
Poverty trap
People living in poverty cannot afford nutritious food for themselves and their families. This makes them weaker and less able to earn the money that would help them escape poverty and hunger. This is not just a day-to-day problem: when children are chronically malnourished, or ‘stunted’, it can affect their future income, condemning them to a life of poverty and hunger. In developing countries, farmers often cannot afford seeds, so they cannot plant the crops that would provide for their families. They may have to cultivate crops without the tools and fertilizers they need. Others have no land or water or education. In short, the poor are hungry and their hunger traps them in poverty.
Lack of investment in agriculture
Too many developing countries lack key agricultural infrastructure, such as enough roads, warehouses and irrigation. The results are high transport costs, lack of storage facilities and unreliable water supplies. All conspire to limit agricultural yields and access to food. Investments in improving land management, using water more efficiently and making more resistant seed types available can bring big improvements. Research by the UN Food and Agriculture Organization shows that investment in agriculture is five times more effective in reducing poverty and hunger than investment in any other sector.
Climate and weather
Natural disasters such as floods, tropical storms and long periods of drought are on the increase – with calamitous consequences for the hungry poor in developing countries. Drought is one of the most common causes of food shortages in the world. In 2011, recurrent drought caused crop failures and heavy livestock losses in parts of Ethiopia, Somalia and Kenya. In 2012 there was a similar situation in the Sahel region of West Africa. In many countries, climate change is exacerbating already adverse natural conditions. Increasingly, the world’s fertile farmland is under threat from erosion, salination and desertification. Deforestation by human hands accelerates the erosion of land which could be used for growing food.
War and displacement
Across the globe, conflicts consistently disrupt farming and food production. Fighting also forces millions of people to flee their homes, leading to hunger emergencies as the displaced find themselves without the means to feed themselves. The conflict in Syria is a recent example. In war, food sometimes becomes a weapon. Soldiers will starve opponents into submission by seizing or destroying food and livestock and systematically wrecking local markets. Fields are often mined and water wells contaminated, forcing farmers to abandon their land. Ongoing conflict in Somalia and the has contributed significantly to the level of hunger in the two countries. By comparison, hunger is on the retreat in more peaceful parts of Africa such as Ghana and Rwanda.
Unstable markets
In recent years, the price of food products has been very unstable. Roller-coaster food prices make it difficult for the poorest people to access nutritious food consistently. The poor need access to adequate food all year round. Price spikes may temporarily put food out of reach, which can have lasting consequences for small children. When prices rise, consumers often shift to cheaper, less-nutritious foods, heightening the risks of micronutrient deficiencies and other forms of malnutrition.
Food wastage
One third of all food produced (1.3 billion tons) is never consumed. This food wastage represents a missed opportunity to improve global food security in a world where one in 8 is hungry. Producing this food also uses up precious natural resources that we need to feed the planet. Each year, food that is produced but not eaten guzzles up a volume of water equivalent to the annual flow of Russia’s Volga River. Producing this food also adds 3.3 billion tons of greenhouse gases to the atmosphere, with consequences for the climate and, ultimately, for food production.
Choose the alternative that presents a possible correct interrogative form of the sentence below.
“In recent years, the price of food products has been very unstable.”
I. _________________ (to lie) in the sun for six hours. That’s why he is sunburnt.
II. Carry is on the phone now. _________________ (to talk) to her sister in Greece.
III. I’m not sure if this is a good book. _________________ (to read) it.
IV. I think I’m a good skier. _________________ (to go skiing) every weekend in the winter.

European Union member states could cut their plastic bag use by 80%, the European commission has said, by
charging for bags or even banning them.
Plastic bags are a major cause ofseaborne pollution, which is a serious hazard for marine life, and some regions have already
moved to cut their use through charging. The UK deputy Prime Minister, Nick Clegg, has pledged to bring forward charges in
England that will affect single-use bags given out by supermarkets.
The European commission is proposing a new directive that would require member states to choose between three methods
ofreducing the waste from bags: charges, national reduction targets, or an outright ban.
The packaging industry has responded by saying that most people use their plastic bags more than once, for instance using
them as bins, but that does not cut the overall use.
When plastic bags, or pieces of them, find their way into the seas, they are a major hazard to marine life. A whale found dead
on the Southern Spanish coast was found to have swallowed 17kg of plastic waste, including plastic bags. Fish, seabirds and
mammals can ali ingest plastic, which they cannot digest and which can clog up their guts or cause choking.
One of the key problems with plastic bags is that they are so light and small that they easily escape into the environment,
defying attempts to recycle them. The European commission has identified this as a key reason for cutting the use ofthe bags,
and other plastic packaging. The first moves to legislate atan EU levei were made in 2011, and today's announcement is likely
to take at least two years to put into practice.
According to the most recent estimates, from 2008, the EU produces 3.4m tonnes of plastic bags in a year.

Teaching English as a foreign language teacher: job description
Teaching English as a foreign language (TEFL) involves teaching adults and children whose first or main language is not English. This can be done in the UK or abroad and the students may be learning English for either business or leisure reasons.
Teaching English to speakers of other languages (TESOL) is also a widely used term and often means the same thing as TEFL. It’s sometimes specifically used to refer to teaching English to people who are living in the UK but who do not speak English as a first language. These students are most commonly refugees and immigrants and need to learn the language in order to help them settle into the UK society.Their courses are often government funded.
Teaching English as a second language (TESL) or teaching English as an additional language (TEAL) may also be terms that are used but they generally all refer to the same thing - teaching English to someone whose native language is not English.
Teachers of English as a foreign language can work in a variety of settingswith different age ranges. This can include commercial language schools, schools and institutions of further and higher education throughout the UK and overseas. Some may also teach in industry, while others are self-employed. Classes are usually taught in English, evenwith beginners. Teaching English as a foreign language teacher: job description

Born in the mid-1980's and later, Generation Y legal professionals are in their 20s and are just entering the workforce. With numbers estimated as high as 70 million, Generation Y (also -1- as the Millennials) is the fastest growing segment of today's workforce. As law firms compete for available talent, employers cannot ignore the needs, desires and attitudes of this vast generation. Below are a few common traits that define Generation Y.
Tech-Savvy: Generation Y grew up with technology and rely on it to perform their jobs better. Armed with BlackBerrys, laptops, cellphones and other gadgets, Generation Y is plugged-in 24 hours a day, 7 days a week. This generation prefers to communicate through e-mail and text messaging rather than face-to-face contact and -2- webinars and online technology to traditional lecture-based presentations.
Family-Centric: The fast-track has lost much of its appeal for Generation Y who is willing to trade high pay for fewer billable hours, flexible schedules and a better work/life balance. While older generations may view this attitude as narcissistic or lacking commitment, discipline and drive, Generation Y legal professionals have a different vision of workplace expectations and prioritize family over work.
Achievement-Oriented: Nurtured and pampered -3- parents who did not want to make the mistakes of the previous generation, Generation Y is confident, ambitious and achievement-oriented. They have high expectations of their employers, seek out new challenges and are not afraid to question authority. Generation Y wants meaningful work and a solid learning curve
Team-Oriented: As children, Generation Y participated in team sports, play groups and other group activities. They value teamwork and seek the input and affirmation of others. Part of a no-person-left-behind generation, Generation Y is loyal, committed and wants to be included and involved.
Attention-Craving: Generation Y craves attention in the forms of feedback and guidance. They appreciate being kept in the loop and seek frequent praise and reassurance. Generation Y may benefit greatly from mentors who can help guide and develop their young careers.

Making Performance Budgeting Work: New IMF Book
October 04, 2007
Member countries will find valuable advice on how to reform their budgeting practices to improve the effectiveness and
efficiency of public expenditure in a major new work on performance budgeting produced by the Fiscal Affairs Department. The book,
Performance Budgeting: Linking Funding and Results (500pp), came off the presses of the top UK publisher Palgrave Macmillan in
September.
Edited by FAD staff member Marc Robinson, the book contains a comprehensive treatment of contemporary performance
budgeting practice and theory. In a series of thematic chapters and case studies, the book discusses:
- The key forms of performance budgeting which [TO IMPLEMENT] around the world - how they differ, and what they have in
common points.
- Lessons from the experience of governments around the world - ranging from OECD nations to developing, middle-income
and transition countries - about what forms of performance budgeting work, under what circumstances, and with what
implementation strategies.
- How successful performance budgeting can improve aggregate fiscal discipline.
- The information requirements of performance budgeting, and
- The links between performance budgeting and other budgeting and public management reforms.
Many of the contributors to this work are leaders in performance budgeting implementation in their countries. Others are
respected academics and technical experts from the International Monetary Fund and other international organizations. Countries
covered in the case studies include the UK, USA, Australia, France, Chile, Spain, Russia, Colombia and Ethiopia.
One major focus of the book is performance budgeting as a tool for improved expenditure prioritization - that is, for helping to
shift limited public resources to the services of greatest social benefit. A key finding is that this type of performance budgeting will only
work if the budget process is fundamentally changed so that top politicians and bureaucrats systematically consider expenditure
priorities when formulating the budget. This means more than just considering the priorities for new spending. It requires also having
mechanisms to systematically review existing spending programs to identify what is ineffective and low priority and can, therefore, be
cut. This is what countries such as Chile and the United Kingdom have successfully done, and the United States is currently attempting
to achieve with its Program Assessment Rating Tool instrument. Conversely, it is a mistake to believe that merely changing the budget
classification and developing performance indicators will in itself improve the allocation of resources in the budget.

Windows
By ScottGilbertsonNovember 19, 2008
Microsoft plans to offer Windows users a new antivirus
package designed to protect the OS from viruses, spyware,
rootkits and trojans. The new software is tentatively code-
named Morro, and will be available for free to Windows XP,
Vista and 7 users sometime in the second half of 2009.
The new software will reportedly use very minimal resources,
which means it should work well with older PCs. If fact,
Microsoft says Morro has been specially designed for older
PCs and low-spec machines popular in developing nations. In
addition to its minimal processor demands, Morro has been
developed to use very little bandwidth,making it ideal for those
without broadband connections.
Morro will replace Microsoft's current, paid service, Windows
Live OneCare, which has been available on a subscription
basis for $50 per year.
While a free, antivirus solution that ships withWindows would
be a boon for the average user, it could also mean trouble for
third-party software solutions. Given that a bundled solution
could raise antitrust concerns -and would no doubt see
competitors likeMcAfee and Grisoft reaching for the lawyers-
Microsoftwill be offeringMorro as a separate download.
Assuming Morro can deliver decent security it should be a
welcome free addition to Windows, but we don't suggest
throwing away your third-party software just yet. Antivirus
software suites will likely continue to hold an edge over Morro
by offering additional handy tools - like passwordmanagers,
identity theft protection and browser-based phishing
protection.
Still, if you've been runningWindowswith no antivirus software
at all,Morrowill no doubt be better than nothing, and it's hard to
arguewith free.
'CityVille' now bigger on Facebook than 'FarmVille'
(Mashable) -- Facebook game developer Zynga has proved once
again that it knows exactly what it needs to do to keep millions of
Facebook users happy and occupied.
In less than a month, its latest game "CityVille"___ ______
(become) the most popular application on Facebook, surpassing
Zynga's previous hit "FarmVille" in all areas.
According to AppData, "CityVille" now has 16.8 million daily
active users, compared to "FarmVille's" 16.4 million. Looking at
monthly active users, "CityVille" is also ahead with 61.7 million
users, while "FarmVille" trails behind with 56.8 million users.
Zynga's "FrontierVille" and "Texas HoldEm Poker" also round out
the top five: put those four apps together (we'll disregard the fact
that many of those users overlap for a second) and you have a
very impressive number: 184 million active users across four
games.
The only non-Zynga app in the top five list is "Phrases," _____ at
one point threatened to take the top place, but is now
overshadowed by both "CityVille" and "FarmVille."
"CityVille's" future success wasn't hard to predict after an
amazingly good start at the beginning of December, but it's still
impressive to see Zynga amassing tens of millions of users in a
matter of days, proving that all that venture capital that went into
the company isn't there by accident.

Business Week - December 5, 2007
by Jennifer Fishbein
It seems like everywhere you turn these days, a new
high-speed train is whisking more passengers across longer
distances faster than ever before. A [NOUN] to Paris from
London is quicker than flying; Japanese bullet trains traverse the
320 miles from Tokyo to Osaka in two and a half hours; and
magnetic levitating trains in Shanghai cut through the city at 268
miles per hour. But while high-speed trains may grab all the
glamour, the more mundane business of subway construction is
what's driving the biggest growth for transportation companies.
Indeed, the world is seeing an unprecedented boom in new
subways and expansion to existing systems. Thanks to surging
economic growth and urban populations, demand for subways is
soaring in China and India. Lots of other places around the
world also are building new lines, from Dubai to Santo Domingo,
capital of the Dominican Republic. And many European and
American cities ? including even such improbable locales as Los
Angeles and Phoenix ? have caught the transit bug.
Problem-Solving and Prestige
Some cities build out of necessity. Rising prosperity
prompted Dubai residents to buy so many cars that they realized
they could [ADVERB] longer drive these cars because they
were stuck in traffic. Others are keen on the environmental
benefits of metros, which produce far less pollution and
encourage drivers to leave cars at home. Some places, mainly
in the Middle East, are looking to diversify their oil-dependent
economies. And others, to be honest, are chasing an urban
status symbol. Building a metro won't turn any old town into
Paris or London, but it does tell the world that you've arrived.
"You have in some cases a prestige issue, which is more
the case in young cities in need of an image," says Jean-Noël
Debroise, vice-president for product and strategy at Alstom
(ALSO.PA), the French transport company that has built a
quarter of the world's metros.
Rennes is an example of the new trend. The city of about
212,000 people in northwestern France was looking to raise its profile when it installed a metro in 2002. It raised the bar by
opting for a driverless system made by Siemens ? just like the
shiny new No. 14 line in Paris ? protecting passengers from the
French penchant for transit strikes. Turin, Italy, did the same to
help win its bid for the 2006 Winter Olympics; its driverless
system opened just before the games. Even the Spanish island
of Mallorca inaugurated a short metro line in April in hopes of
luring even more tourists to its capital, Palma. Alas, it closed
indefinitely in September due to flooding, amid charges of
mismanagement.
A Boon for Transit Builders
The world's three largest metro manufacturers, Montrealbased
Bombardier (BBDB.TO), Alstom, and Munich-based
Siemens (SI) report high demand for mass transit, including
tramways and light-rail systems that run both under and
[PREPOSITION] ground. The global subway market was worth
9.3 billion dollars in 2005 and is projected to grow at a rate of
2.7% per year until 2015, according to a 2007 study by the
European Railway Industry Assn. Subway lines [TO BUILD] or
extended in 20 European cities and five Middle Eastern ones,
and dozens of towns are constructing light-rail systems, reports
the Brussels-based International Association of Public
Transport.
The size of a city determines its need for a metro system.
Cities of a few million people ? or those anticipating huge
population growth ? really can't do without a mass transit
system. But cities of one or two million inhabitants can choose
between a subway and a surface tramway, which costs far less
but also runs more slowly. [CONJUNCTION] funding is an issue,
cities usually will spring for a subway, says Debroise. "The
tramway has a very old image of the 19th century, with horses in
the streets," he says.

YOUTH PROLONGED: OLD AGE POSTPONED
by Robert Weale (King's College London, UK)
What exactly is human ageing? Can it be slowed down?
These questions have puzzled scientists and laymen alike
for generations, and continue to do so today. The author
addresses these thought-provoking issues by challenging
pre-conceived notions of age-perception, age-acceptance
and inter-age relations. Pertinent matters of age-related
communication are dealt with, and the reader is treated to
a grand tour of the latest theories of ageing, age-related
biological changes and age-related diseases, such as
Alzheimer's Disease. Here, the author's expertise in agerelated
eye diseases truly comes into its own.
Weale's unique work not only underlines important
genetic and avoidable risk factors but gives ample
consideration to possible consequences stemming from
different early lifestyles. Readers will re-consider their
ideas of what it means to age, and gain a better
understanding of what can and cannot slow down the
process of ageing.
