Scientists are uncovering the secrets of two port cities lost under the waters of the Medi

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(列支敦士登基金会).
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(海洋考古学家) and others, are using high powered vacuums, satellite navigation systems and sophisticated sonar(声纳) 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.
【小题1】The reason why the two port cities disappeared under the waters of Mediterranean Sea is that .A．the two port cities were destroyed by huge earthquakesB．the disappearance of the two port cities was caused by underwater landslideC．rising seas and a shift in the Nile River outlet doomed the citiesD．the story didn’t tell us at all【小题2】 From the story we can draw a conclusion that .A．the two port cities were famous for their wealth and the mysteryB．the two cities belonged to FranceC．some mysterious creatures from other planets destroyed the two citiesD．the American Geophysical Union conference was once held in one of the two cities【小题3】 This article is probably from .A．a scientific magazineB．a report to the governmentC．a school text bookD．a scientific report in a newspaperD

(答案→)D 解析：本文报道了人们对法国地中海中的两座城市沉如海底的各种推测。【小题1】推断题。文章只对城市下沉的原因作了一些推测但未作出结论。由此可推知此题答案为D。【小题2】推断题。根据文章中所提到的与之相关的名称，如：French underwater explorer Franck Goddio, a Paris-based underwater research organization, Napoleon’s fleet可推知此题答案为B。【小题3】推断题。文章讨论地中海中的两座城市下沉的原因，显然与地质科学有关，故选D。注意不宜选A，一个显然的因素是第1段中出现的yesterday。
