Christmas is the most important annual festival in both Britain and North America. In its origins, it combines the Christiancelebration of the birth of Christ, on 25 December, with the ancient tradition of a winter feast during the darkest period of the year.

CELEBRATION

B12

Christmas carols — a special kind of religious songs — are an important part of it. You may hear them countless times over the radio but it is quite different when you listen to people sing carols around you in church.

At this time, too, many carol singers make door-to-door visits to people at home, collecting money for this or that charity.

The first Arbor Day took place in April, 1872 in Nebraska. It was the brainchild of Julius Sterling Morton (1832-1902), a Nebraska journalist and politician originally from Michigan.

 POLITICS

B12

When he became a member of Nebraska’s state board of agriculture, he proposed that a special day be set aside dedicated to tree planting and increasing awareness of the importance of trees. Nebraska’s first Arbor Day was an amazing success.  More than one million trees were planted.

Every year more than eleven million tourists visit Britain. Most visitors come in the summer months when they can expect good weather.

Tourists usually spend a few days in London, then go on to other well-known cities.

Perhaps the least visited places in England are old industrial towns.

Australia is an island continent and the world’s sixth largest country. The continent and the island of Tasmania, off its south-eastern coast, make up the Commonwealth of Australia.

 SOUTH-EAST

Australia is a federation of six states and two territories. The largest State, Western Australia, is about the same size as Western Europe. The country has a parliamentarysystem of administration modelled on the British one, and the state and federal structures are broadly similar.

Australia’s system of administration is based on the democratic tradition.

It is difficult to tell exactly how many languages there are in the world today. Scientists say there are about 2,700 languages, but no one has ever made a more definite count.

 SCIENCE

B12

In most countries there are at least two native languages, and in some cases — as in Cameroon — there are hundreds. The number of languages naturally changes as tribes die out or linguistic groups are absorbed.

 NATURAL

B13

Nowadays, globalization influences thedevelopment of languages. New words appear, existing words acquire new meanings, native words give way to international terms.

Almost all languages change. A rare exception is written Icelandic, which has changed so little that speakers of modern Icelandic can read sagas written a thousand years ago.

If you drew a map of Europe based on languages, it would be different from a conventional map. For example, Switzerland would practically disappear, becoming part of the surrounding areas of French, Italian, and German.

If James Harrison (1816-1893), a Scottish immigrant to Australia, didn’t accidentallypush ether gas into a metal tube, people might still be using boxes filled with blocks of ice to cool their food.

 ACCIDENTAL

B13

The main problem was how to overcome the need for ice in the refrigeration process.

 REFRIGERATE

B14

Ice had to be cut fresh from frozen lakes and stored inside an underground house until it was ready to be used as a cooler.

 COOL

B15

Australians had difficulty gaining access tonatural ice since Australia does not enjoy that many lakes.

 NATURE

B16

Harrison’s discovery was beneficial the world over, but especially important for Australia because now it could export frozen meat to Europe. He even tried one such journey to Europe, but the ether had leaked during the voyage and ruined the entire cargo. Harrison went bankrupt but his legacy meant a huge difference to the Australian economy.

Water is a vital element in each of our lives. Not only is it essential to our health, but we also use it for various household tasks. Every day we use water for cooking, bathing, and cleaning, and drinking; but how often do we think about its source?

 VARY

B12

Consumers receive their water from one of two sources: a private well, or a community water system.

 CONSUME

B13

Approximately 15 percent of the U.S. population relies on individually owned and operated sources of drinking water, such as wells, cisterns, and springs. The majority of household wells are found in rural areas.

 INDIVIDUAL

Those who receive their water from a private well are solely responsible for the safety of the water.

 RESPONSE

B15

Private wells are not subject to different federal regulations and are generally regulated on a very limited basis by states.

Local health departments may assist well owners with periodic/periodical testing for bacteria or nitrates, but the bulk of the responsibility for caring for the well falls on the well owner.
