Scientists are uncovering the secrets of two port cities lost under the waters of the Mediterranean Sea, a researcher said yesterday.

Herakleion and Menouthis were rich and proud cities until something reduced them to rubble (碎石) and buried them in the mud beneath 30 feet of sea water, French underwater explorer Franck Goddio said at the American Geophysical Union conference.

“This is a mystery that is ongoing,” said Goddio, a founder of the European Institute of Marine Archeology, a Paris-based underwater research organization backed by the wealthy Hilti Foundation of Liechtenstein(列支敦士登基金會).

The destruction of the twin port cities has haunted Goddio ever since he happened upon the site about 15 miles from Alexandria while exploring sunken ships from Napoleon’s fleet.

Goddio and his group of expert divers, marine archeologists(海洋考古學家) and others, are using high powered vacuums, satellite navigation systems and sophisticated sonar(聲納) to excavate(挖掘) the sunken cities from underneath a carpet of silt about one meter (three feet) high.

Walls of shops, remains of streets and gold artifacts have been found and recovered.

Some experts believe that the port cities were destroyed by a series of massive earthquakes, much like the quakes scientists believe felled Troy(特洛伊城), Jericho and other ancient cities. The uniform. direction of the collapsed columns and walls suggest an earthquake, Goddio said, but no fault lines have been found nearby.

Other researchers believe a massive wave, caused by either an offshore earthquake or a distant underwater landslide, could explain the catastrophe. Still others think rising seas and a shift in the Nile River outlet doomed the cities.

“The argument, as you can see, continues,” Goddio said.

【答案與解析】本文報道了人們對法國地中海中的兩座城市沉如海底的各種推測。

1. D。推斷題。文章只對城市下沉的原因作了一些推測但未作出結論。由此可推知此題答案為D。

2. B。推斷題。根據文章中所提到的與之相關的名稱，如：French underwater explorer Franck Goddio, a Paris-based underwater research organization, Napoleon’s fleet可推知此題答案為B。

3. D。推斷題。文章討論地中海中的兩座城市下沉的原因，顯然與地質科學有關，故選D。注意不宜選A，一個顯然的因素是第1段中出現的yesterday。
