Unique Tradition from UK
Boxing Day
This holiday, which is observed on December 26, is a unique part of the Christmas season in Great Britain, as well as other Commonwealth nations. Boxing Day comes from a tradition that began in the Middle Ages more than 800 years ago. On this day, English churches would open their ‘alms box’ and distribute its contents to needy members of the community. It was also a day for servants to celebrate the holidays with their families, having usually worked the day before. Today, Boxing Day is one of the twenty-two paid holidays received by most working Brits. Most people now spend Christmas Day with their family and reserve Boxing Day for exchanging gifts with friends. Although the government shuts down for the day, cinemas and theatres are open.
Queen’s Telegram
In the United States, if you make it to the ripe old age of 101 or 102, Willard Scott will wish you happy birthday on national television. In England, the queen herself will send her congratulations. This fairly new custom is known as "the Queen’s Telegram" and assures centenarians (people at least 100 years old) that they will receive a birthday telegram from the queen on their one-hundredth birthday. The telegram is so longed for by some Brits that one 98-year-old woman was recently proven to have faked her age by two years just to receive the telegram.
High Tea
High tea was first enjoyed by the English working class during the 1700s. This ritual (仪式) began as a practical attempt to hold off hunger pains between breakfast and supper, as eating just two daily meals was common at the time. It was called “high” tea because it was usually taken sitting on top stools in a tea shop or standing at a counter or buffet table. Today, high tea has become a more elegant and popular tradition that is practiced in fine hotels and restaurants around the world.
Public Houses
Visiting a pub is one of Britain’s oldest forms of entertainment. The idea for the first public houses was brought to Britain thousands of years ago by conquering Roman army. The first pubs served only wine, but after the discovery of hops(啤酒花) in the fourteenth century, pubs began to serve mainly beer and ale(麦芽酒), as they do today.
British pubs operate between 11 a.m. and 11 p.m. every day except Sunday, when they must close at 10:30 p.m. The drinking age in Britain is eighteen, but fourteen-year-olds may enter a pub unaccompanied if they order a meal.

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入最恰当的单词。

注意:每空格1个单词。

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).

But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.

The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.

Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.
