Great Flood Evidence FoundA team of National Geographic explorers travelling around the Black Sea, which is located between Europe and Asia, has found that people once lived in an area that is now deep under water. The discovery is the latest evidence(证据) supporting the idea that a huge flood swamped the area 7,500 years ago and created the Black Sea.
An underwater robot found several submerged (under the surface of the sea) artifacts (things made by man), including shine tools and wood-and-clay buildings. The artifacts lay about 90 meters below the surface of the sea and 19 kilometers north of Turkish coast.
The notion (belief) that an ancient flood created the Black Sea was hatched several years ago by two geologists, Bill Hyan and Walter Pitman, of Columbia University. They speculated(considered) that the Mediterranean Sea began to rise at the end of the last ice age, 15,000 years ago. The big ice sheets that covered large parts of the Northern Hemisphere started to melt, and the meltwater drained into the Mediterranean. Water from the rising sea pressed against a large wall of rock that existed on the sea's western shore. Behind that wall of rock lay a large freshwater lake.
Over the centuries, the pressure of the water became more and more intense (very great). Finally, in one giant push, the water broke the wall of rock and poured into the inland lake. In a matter of days, the lake doubled in size. The salt in the incoming water turned the lake into a real sea-the Black Sea. The rushing water probably drowned many lakeshore inhabitants.
The explorers are continuing to search for more signs of ancient habitations beneath the Black Sea.

A.some ancient people lived where the Black Sea is
B.stone tools were first made some 7,500 years ago
C.wood-and-clay buildings stand water wash well
D.ancient people were able to live under water
3.The underlined word “hatched” has about the same meaning as ________.
[ ]
4.Which of the following statements is true according to the passage?
[ ]
A.A large wall of rock built by ancient people protected them from being flooded.
B.It was the pressure of ice sheets that led to the collapse of the rock wall.
C.It took 7,500 years for the water to accumulate enough power to break the wall.
D.The Mediterranean area had the most ancient human civilization in the world.
5.The discovery made. by the team of explorers ________.
[ ]
A.needs further support
B.is just an imagination
C.has been widely accepted
D.has proved the existence of ice age
解析:
1.A 通读全文可知,本文主要讲述了黑海的形成。 2.A 从第一段的第一句话A team of National Geographic explorers travelling around the Black Sea, which is located between Europe and Asia, has found that people once lived in an area that is now deep under water.可以看出答案。 3.D 根据语意和后面的解释,本句应表示“古代的一个洪水创造了黑海这一观点是几年前由两名地理学家所提出(想出)的”。所以,hatched应与thought of意思最相近。 4.C 文章第一段最后一句提到一个巨大的洪水在7,500年前淹没了这一地区形成黑海,而不是花了7500年这些水才急剧了足够的力量冲倒这个墙。 5.A 从文中的第三段的They speculated (considered) that the Mediterranean Sea Megan to rise at the end of the last ice age, 15,000 years ago.可知这只是一种猜想,所以还需要更多的支持。 |
