When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.

Underwater archaeology the study of ships, aircraft and human settlements that have sunk under large bodies of water―is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment. Besides the Swedish ship wreck(殘骸), underwater archacologists have made more exciting discoveries such as the 5,000-year-old boats in the Mediterranean Sea.

Underwater archacology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archacologists want to study these objects to add to the world’s knowledge of history , but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts  that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines (挖掘機)often used to repair ports. These machines destroy, wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.

      A．To provide background information of the topic.

       B．To attract readers’ attention to the topic.

       A．sea hunters have better diving equipment

       B．their knowledge of world history is limited

For centuries ,the only form of written correspondence（通信）was the letter .Letters were ,and are ,sent by some form of postal service ,the history of which goes back a long way. Indeed ,the Egyptians began sending letters from about 2000 BC, as did the Chinese a thousand years later.

       Of course ,modern postal services now are much more developed and faster ,depending as they do on cars and planes for delivery .Yet they are still too slow for some people to send urgent documents（緊急文件）and letters.

       The invention of the fax（傳真）machine increased the speed of delivering documents even more .When you send a fax ,you are sending a copy of a piece of correspondence to someone by telephone service .It was not until the early 1980s that such a service was developed enough for businesses to be able to fax documents to each other.

       The fax service is still very much in use when copies of documents require to be sent ,but ,as a way of fast correspondence, it has been largely taken the place of by email. Email is used to describe messages sent from one computer user to another.

       There are advantages and disadvantages with emails. If you send someone and email, then he will receive it extremely quickly. Normal postal services are rather slow as far as speed of delivery is concerned.

       However ,if you write something by email ,which you might later regret ,and send it immediately ,there is no chance for second thoughts. At least ,if you are posting a letter you have to address and seal（封）the envelope and take it to the post box .There is plenty of time to change your mind. The message is think before you email!

       C．the fax machine was invented after the 1980s

       D．letters have been used in Egypt for about 2,000 years
