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.

本文是一篇夾敘夾議的文章,向我們闡述了水下考古的意義和發(fā)展以及水下考古面臨的困境。

63.B.

解析:推理題。一般說明性質的文章比較乏味,因此為了我們能更具體明確的了解到水下考古的意義,文章開始用講故事的方式把我們引到考古學這個方面來,后面大篇幅的將是水下考古的意義和發(fā)展。

64.C.

解析:細節(jié)題。從文章第二段可以看到:Underwater archaeology---the study of ship,…under large bodies of water.水下考古的目的是研究船只,文物,和human settlements. B 是搜尋水下文物,文中未提;D說的是檢查水下環(huán)境,更談不上。

65.D.

解析:細節(jié)題。文中有:One enemy is treasure hunters who dive….Once sold, these objects are lost to experts.盜文物會使得文物流失而不能進行科學的分析和研究。C答案中注意的是dredging machines是在維修port在這個過程有破壞的是destroy wrecks and artifacts or bury them deeper under sand and mud.因此不能選。

66.A.

解析:主旨大意題。文章的結構是先引出topic-Underwater archaeology,然后根據(jù)這個主題討論了其發(fā)展以及現(xiàn)在所面臨的困境,文章始終都是圍繞水下考古這個主題展開的。

Being alone in outer space can be frightening. That is one reason why astronauts on solo(單獨的) space flight were given plenty of work to keep them     45    . They were also in constant communication with people on the earth,    46    , being with people from whom you cannot get away might be even harder than being alone. This is what happens on long submarine(潛水艇) voyages. It will also happen on     47     space flights in the future. Will there be special problems of adjustment under such conditions?

Scientists have studied the reactions of men to one another during long submarine voyages. They have found that the longer the voyage lasts, the more serious the problem of    48    is. When men are     49     together for a long period, they begin to feel uneasy. Everyone has little habits of speaking and behaving that are ordinarily acceptable. In the limited space over a long period of time, however, these little habits may become very     50    .

Apparently, although no one wants to be     51     all the time, everyone needs some degree of privacy. When people are enclosed together, they are in what is called a stress situation. That means that they are under an unusual amount of     52     or stress.

People who are well-adjusted are able to     53     stress situations better than others. That is one reason why so much care is taken in     54     our astronauts. These men undergo a long period of testing and training. One of the things tested is their behaviors under stress.
