      That little "a" with a circle curling around it that is found in E-mail addresses is most commonly referred

to as the "at" symbol.

      Surprisingly though, there is no official, universal name for this sign. There are dozens of strange terms

to describe the "@" symbol.

      Before it became the standard symbol for electronic mail, the "@" symbol was used to represent the cost

of something or how heavy something is. For instance, if you purchased 6 apples, you might write it as 6

apples "@" $1.10 each. 

      With the introduction of e-mail came the popularity of the "@" symbol. The "@" symbol or the "at sign"

separates a person's online user name from his mail server (服务器) address. For instance,

joe@uselessknowledge.com. Its widespread use on the Internet made it necessary to put this symbol on

keyboards in other countries that have never seen or used the symbol before. As a result, there is really no

official name for this symbol.

      The actual origin of the symbol remains a mystery. History tells us that the @ symbol came from the

tired hands of the Middle Ages. During the Middle Ages before the invention of printing machines, every

letter of a word had to be copied with great efforts by hand for each copy of a published book. The monks

that performed these long, boring coping duties looked for ways to reduce the number of individual strokes

(笔画) per word for common words. Although the word "at" is quite short to begin with, it was a common

enough word in text and documents so that those monks thought it would be quicker and easier to shorten

the word "at" even more. As a result, the monks changed the shape of "t" into a circle to surround "a", thus

leaving out two strokes in the spelling "t".

1. Which of the following is the best title of the passage? [ ]

A. How"at" developed into @.

B. How @ came into being.

C. How monks invented @.

D. How people wrote the cost of something.

2. Which is NOT the reason for the monks to spell "at" as @? [ ]

A. Though "at" is short, it was used very often.

B. The monks wanted to be quicker and easier with their copying.

C. The monks wanted to invent a new word.

D. Copying work was long and boring for them.

3. According to paragraph 5, which is TRUE about the symbol of @ today? [ ]

A. When you are online, you must use the @ symbol.

B. Kittly 163.com @ is an email address.

C. In countries where @ is used, governments have given it an official name.

D. It is likely to find the @ symbol on computer keyboards worldwide.
