British English and American English

A student is studying British English. He wonders: Can I have a talk with Americans? Can they catch me? Learners of English often ask--what are the differences between British English and American English? How important are these differences?

Certainly, there are some differences between British English and American English. There are a few differences in grammar(语法). For example, speakers of British English say “in hospital” and “Have you a pen?” Americans “in the hospital” and “Do you have a pen?” Pronunciation (发音) is sometimes different. Americans usually sound the “r” in words like “car”and “farm”. Some speakers of British English do not sound the “r” in these words. There are differences between British English and American English in spelling and vocabulary. For example, “colour”and “honour” are British English spellings. “Color” and “honor” are American English spellings.

These differences are in grammar, pronunciation, spelling and vocabulary. However, they are not important. For the most part, British English and American English are the same language.

A Christina from Spain

  On the last day of the year, the 31st of December, people wait till 12 pm. Everybody must have 12 grapes(葡萄) to eat at midnight. At each sound of the clock, we must eat a group. But we can’t ever finish eating the grapes on time! Usually when people still have some grapes in their mouths, they look at each other and start to laugh. This tradition started in Spain long ago. One year, when there were a lot of grapes, the king of Spain decided to give grapes to everybody to eat on New Year’s Eve.

B Cordon from Britain

On New Year’s Day in Britain, people have parties. At 12 o’clock, the music stops, and we listen to the radio. On the radio we hear Big Ben, the famous clock in London. Then everybody sings a song about friendship and kisses their friends. We say “Happy New Year” to each other. It’s lucky if a tall man with dark hair is the first person to come to the house in the new year. So I go and visit as many friends as I can. They all give me a drink.

Have you ever heard an echo of your voice?

An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.

We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒).

Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.

A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.

We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.

1.What is called “echo”?

A.Very loud voices.

B.Very loud voices that are made by man.

C.Very loud voices that are made by animals.

D.The sound that is made by man or animals comes back from some place.

2.We can hear our echoes if we     .

A.shout in a small room

B.shout in a large house full of things

C.shout in narrow valleys(山谷)

D.shout in the open air

3.Which is the right order of hearing our echo in a very large, empty hall?

a. We hear the reflected sound

b. The sound returns to us

c. The sound hits the walls

d. We make a sound

A.c, b, a, d          B.c, a, b, d           C.d, c, b, a           D.d, b, c, a

4.From the text we learn that __________ .

A.reflected sound is useful only to blind people

B.people haven’t made use of reflected sound yet

C.bats use reflected sound to fly and get food

D.whales don’t use reflected sound as they live in the sea

5.If you haven’t got a megaphone, ____ will help you to make your voice travel farther.

A.a long piece of wood                     B.a roll of cardboard

C.a thin thread                           D.a long piece of silk
