Most people know that a wedding ring is symbolic of the bond(连结物) of love and commitment（承诺） between two people. But not everyone knows about the history behind this small yet powerful symbol. The history of the wedding ring goes back not just hundreds but thousands of years. No other currently practiced wedding tradition has been around as long. 
The Egyptians were the first recorded civilization to use the wedding ring. In Egyptian hieroglyphics（象形文字） a circle represented eternity. Once a woman accepted the ring she became the “property” of the person who gave it to her and she was in a sense “his.” The first wedding ring could have been made of braided grass or hay （which would have been changed often）, ivory, bone, or leather.  Eventually, metal was used, but the first wedding bands were crude（未加工的） and rough. However, the sentiment（情感） remained the same-eternal commitment and love. 
The Egyptians wore the wedding ring on the left hand because it was believed that a vein（静脉） in the left hand went straight to the heart. This tradition is still commonly practiced today in most parts of the world largely for practical purposes （most people are right handed.）It is worn on the fourth finger of the left hand. But there are some countries and groups which do not follow this tradition.  In the Jewish faith, the wedding ring is put on the index finger. Roman Catholics traditionally wore their wedding band on the right hand, and in many countries and regions in Europe some people still follow this tradition. 
It is interesting to note that in the long history of the wedding ring that it is only in the last century that men have begun to wear them. However, now both men and women show their love and commitment by exchanging rings on their wedding day. 
Once you begin shopping for rings you may be amazed by the choices that await you. There are several different types of metals: traditional gold, white gold, platinum, and titanium. You can have an inscription（刻字） put on the inside of the band（镶边） if you like. Some people are even choosing a tattoo（刺花） band. The styles vary from a simple, yet elegant（优雅的） band to an elaborate（精致的） ring covered with jewels. If you do not buy the wedding and engagement rings as a set you will want to be sure the styles are compatible（一致的）. Choose carefully because this choice will need to stand the test of eternity.

Every human being has a unique^① arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original^② pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

Finger-prints can be made very easily with printer’s ink. They can by recorded easily. With special methods, identification^③ can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

Notes:

unique  adj. 唯一的，独特的

original  adj. 最初的，原始的

identification  n. 辩认，鉴定

The average person learns most of the 30 000～40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious(意识到的) effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently(永久的)by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it.

Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious(认真的), write the word and its meaning in a personal vocabulary list — preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days.

Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read.

Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing them enables you to make intelligent guesses about the meaning of words.

If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited(继承) or borrowed much of its vocabulary of 500 000～600 000 words from Latin, Greek, French, Spanish and German.

When you meet a new word in reading, what should you do?

A. Guess its meaning.                              B. Ask somebody.

C. Look it up in a dictionary.                     D. All of the above.

According to this passage, the best way to build a good vocabulary is ___.

A. to remember a lot                                 B. to read a great deal

C. to take part in a lot of good talks            D. both B and C

The phrase “be alert to” in the third paragraph may best be replaced by “___”.

A. look at                                               B. pay attention to 

C. write down                                         D. learn by heart

In the fourth paragraph, the word “them” refers to ___.

A. the parts of words                                 B. prefixes

C. suffixes                                                D. roots
