| Stop Spam When I first got an e-mail account ten years ago, I received communications only from family, friends, and colleagues. Now it seems that every time I check my e-mail, I have an endless series of advertisements and other correspondence that do not interest me at all. If we want e-mail to continue to be useful, we need specific laws that make spamming (发送垃圾邮件) a crime. If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to send hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products, individual (个人的) e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time? This problem is troubling for individuals and companies as well. Many spam e-mails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks. These computer problems raise production costs of companies, which are, in the end, passes on to the consumer. For these reasons, I believe that lawmakers need to legislate (立法) against spam. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience. | |

| For centuries, the only form of written correspondence (通信) was the 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 service now are march more developed and faster. depending as they do on cars and planes fore delivery. Yet they are still too slow for some people to send urgent documents (紧急 文件) and letters. The invention of the fax (传真) 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 form one computer user to another. There are advantages and disadvantages with emails. If you send some one an 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.

| 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. Underwaterarchaeology-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 (残骸), underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea. Underwater archaeology can provide facts abut 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 peoples way of life and their systems of trade in ancient times. Underwater archaeologists 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 (挖掘机) 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. | |
