2. In the following gapped text decide which fragments (a-d) best fit each space (1-4).
“The recent magnitude-9.1 earthquake in Sumatra and the devastating tsunami that followed killed some 300,000 people. That extraordinary loss of life has focused attention on the earthquakes and their power to move water. But large volumes of volcanic debris falling into the sea can also generate devastating tsunamis, multiplying the effect of a volcanic collapse far beyond the avalanche itself. 1…………
The most catastrophic volcano-related tsunami in recorded history took place in 1792. The collapse of Mayu-yama lava dome at Unzen volcano, in Southern Japan, caused a debris avalanche that rocked the Ariake Sea. Tsunamis inundated the city of Shimabara as far as the gates of its castle, and swept along a forty-three-mile long segment of the Shimabara Peninsula. 2………..
But the event pales in comparison with the size of what the collapse of massive oceanic island volcanoes would cause. The huge volcanoes in Hawaii, the Canaries, and the West Indies, for instance, are several orders of magnitude larger than Mayu-yama lava dome. Seafloor studies around those island volcanoes indicate that massive deposits of debris from avalanches ring the islands as far out as 150 miles.
Two kinds of island and underwater collapses have been identified: slumps and debris avalanches. Large slumps typically creep slowly, though occasionally they lurch a few feet in response to an earthquake without substantially disrupting the volcano. 3......
The massive volume of submarine landslides can create very large tsunamis, often called mega tsunamis. Rocks with coral deposits 230 feet above sea level on Molokai and 1,200 feet on the top of Lanai in the state of Hawaii have been interpreted as tsunami deposits. Some controversy remains, though, in part because the rates of uplift and subsidence of those islands since the time of collapse are not well known. 4…………
Models and computer simulations of how tsunamis propagate after large underwater landslides have focused primarily on the Hawaiian Islands and on one volcano in the Canary Islands: Cumbre Vieja on La Palma.”
The fragments are:
a) The waves then traveled across the bay, washing away nearly 6,000 houses and 1,600 fishing boats along another seventy-five miles of shoreline. About 14,500 people were killed.
b) Debris avalanches, in contrast, move at high speed, and they often transport fragmented debris over long distances, including blocks as large as six miles wide. The surface topography of such a debris field on the sea floor is comparable to that deposited by terrestrial avalanches.
c) Out of roughly 25, 000 fatalities from large volcanic landslides in historic times, nearly four-fifths of them resulted not from debris avalanches themselves or the associated volcanic eruptions, but from tsunamis.
d) At Kohala volcano on the Big Island of Hawaii, however, where height changes have been well documented, tsunami deposits were likely carried between 1,100 and 1,600 feet above sea level when neighboring Mauna Loa volcano collapsed.
3. Read the text below and answer the questions in the space provided.
According to the conventional view, from soon after its formation about 4.5 billion years ago until 2 to 2.5 billion years ago, Mars was a watery world like Earth, with luxuriant seas, perhaps even an ocean, that might have supported life. These large bodies of water were gradually lost through climate change, caused by a decline in volcanic activity and the whittling away of the planet’s atmosphere by radiation from the sun. Some water remained frozen in the polar caps, but most drained into the rocks and froze. While there can be no misleading that water did exist on Mars in large quantities, as new information from Mars’s many probes and landers comes in, it is looking increasingly likely that this simple tale isn’t true. Instead, the “warm, wet phase” of Mars, when life might have originated, was actually quite short-lived, lasting less than a billion years, and was followed by a series of extreme conditions unlike any experienced on Earth. If this is true, Mars’s reputation a once-habitable planet that may still harbor microscopic life is at stake. A billion years might well have been long enough for life to emerge - indeed it appeared within that time frame on Earth-but the speed with which those conditions vanished would have made it much more difficult for that early life to truly establish itself.[…] Since the planets were most severely bombarded early in the formation of the solar system, and since lava from Mars’s volcanoes can cover evidence of bombardment, Gerhard Neukum assumed that area with fewer craters are younger.

Tape script:
On 22 January, international scientists produced a frightening 1,000-page report on global warming. The 1990s were the warmest ten years for 1,000 years, they say. Temperatures will go up even more quickly in the next 100 years. The sea will be 88 centimetres higher than it is now. Millions of people in China, Bangladesh, Egypt and other places will lose their homes in terrible floods. Why is this happening? And what can we do to stop it?
Most people agree that carbon dioxide in the air is the biggest problem. It is produced when we burn gas and oil. In November 2000, 160 countries met in The Hague to discuss this problem, but nothing was decided. Europe and China want to produce less carbon dioxide. The USA, Australia, Canada, Russia and Japan disagree. They think that we should just plant more trees. 'More trees will cool the world,' they say.
Other people don't believe that there is a problem at all. International oil companies are paying scientists lots of money to prove that global warming doesn't exist. Their money has also helped an oil man to become the President of the USA. George W Bush worked in the oil industry for many years, 'I don't think global warming is a problem,' he says.
While governments do nothing, the world is getting hotter. There are more and more disasters because of global warming. Last summer, the USA had the worst fires in its history, and Northern Europe had its worst floods. In February 2000, heavy rain and storms brought serious floods across southern Africa. Southern Botswana received 75% of its usual yearly rainfall in only 3 days. Polar bears are dying near the North Pole because the ice is melting. This is already making the sea higher. The north of Egypt, for example, is losing 148 metres of land under the sea every year. There have been serious droughts in North Korea (1997), Afghanistan (2000) and Sudan and Ethiopia (1998-2000). The Yellow River in China ran dry in 1998 and 1999. There have even been reports of unusual illnesses in America: West Nile fever in Boston and malaria in New York.
Is there any hope for the future? Some people think that solar and wind energy is the answer. Germany already has 100,000 solar roofs. The USA has plans for 1 million. But there are some problems – like carbon dioxide – that countries cannot solve alone. Let's hope that at the next meeting, governments will stop fighting and start working together. If they don't do something now, what kind of world will there be for our grandchildren?
