One thing Britain is famous for is pubs, and no trip to the UK would be complete without a visit to one of the thousands of pubs across the country.

Pubs play an important part in the social structure of the country. They are places where all ages and social classes mix to talk, do business, or just spend a couple of quiet hours before heading home in the evening.

There are many different types of beer available in pubs. Traditional British beer is called bitter, or ale, and is usually served at room temperature. As a result, the British are famous for their ‘warm beer’! If you prefer a cold beer, ask for lager. This beer is a light yellow in colour whereas bitter is usually a darker brown. All beers are served as pints (500 ml) or halves (250ml). To order, you need to ask for a pint or half, and then name the beer. So, you could say “ .”

Wine, red or white, is normally available in all pubs, as are spirits such as whisky, gin or vodka.

It is not, however, necessary to drink alcohol. Non-alcoholic drinks are called soft drinks. You can have juice, lemonade or cola, among others.

If you visit a pub in a group, it is important to pay for your ‘round’. This means that you buy a drink for everyone in your group. Not buying your round is a big social mistake! Remember that you need to order and pay for your drinks at the bar.

So, follow these tips if you want to get the most out of visiting a pub, and, “cheers!”

Every day millions of letters go from one country to another. Letters mailed in Italy are received in Japan. Letters mailed in Canada are received in Africa. On the letters are many different kinds of stamps，bought in different countries．

The Universal Postal Union helps each letter get to the right place as quickly as possible. It sets up rules about the size and weight of letters，postcards，and small packages（包裹）. It has rules that all countries must follow about international postal rates（费用）．

One hundred years ago，international mail did not move so smoothly. One country did not always accept another country’s letters. Letters from some countries were too large to fit into the mailboxes of other countries. Letters travelled by many different routes（路线）．Some were lost along the way．

Sometimes the person who sent the letter could pay only part of the postage. The person receiving the letter had to pay the rest．
