Japanese Drilling into Core of Earth
In what resembles a journey to the center of the Earth, Japanese scientists have launched the world’s first attempt to bore a hole into the red-hot core of a volcano and unlock the secrets of deadly eruption.
A 50-meter-high oil-rig-like derrick perched on the scrubby slopes of Japan’s Mount Unzen will begin drilling through the volcano’s crust next week in a bid1 to sample the magma bubbling below2.
The aim is to study how the liquefied rock causes menacing gas buildup, said team leader Setsuya Nakata, of the University of Tokyo’s Earthquake Research Institute.
“Gassing is important because it controls the explosivity of eruptions,” Nakata said. “The results can be expanded to anti-disaster research.”
Mount Unzen , a wind-swept 1.486-meter dome on the southern island of Kyushu, is a perfect model. It erupted in 1991, showering avalanches of hot rocks over a nearby town, killing 43 people and leaving nearly 2,300 homeless. Another 11.000 people were evacuated from the area until 1995, when the volcano had stabilized.
The results are particularly important to a nation like Japan, where the meteorological agency monitors 20 dangerous peaks. Perhaps Japan’s most famous volcano is snowcapped Mount Fuji, which last erupted in 1707 and sprinkled Tokyo with ash.
The drilling on Mount Unzen will begin very soon from an altitude of 850 meters on its northwest slope. Scientists hope to tap a magma vent around sea level by August and extract a 200-meter-long core sample by summer 2004.3
Boring into the glowing magma at that level would normally be impossible, because of its fiery 700 degree Celsius heat. Thus, a slurry of water will be pumped into the drill shaft to cool the magma and allow the drill head to cut through.
Nakata said there is no danger of triggering another eruption.4

1. According to the passage, Mount Unzen A erupted in 1707.
B erupted in 1991.
C erupted in 1995.
D several times in the last century.
2. According to the passage, the study of the Mount Unzen volcano may benefit Japan in all the following aspects
EXCEPT
A finding causes of volcano eruptions.
B helping to launch anti-disaster research.
C looking into the connection between liquified rocks and gas buildup.
D predicting volcano eruptions.
3.Why is this research project so important to Japan?
A. Because Japan has many living volcanos. B Because Japan wants to turn Mount Fuji to a dead volcano. C Because volcano gas could be a source of energy. D Because Japan is testing a new way of drilling into the earth.
4. The drilling site on Mount Unzen is A around the sea level. B on the northeast slope of the mountain. C about half way up the mountain. D as high as 1,486 meters.
5. The title of this passage Japanese Drilling into Core of Earth actually means that they A drill a hole into the core of a volcano. B bore into the rocks near the volcanic vent. C conduct an imagery journey to the core of a volcano. D regard magma as the core of Earth.
答案與題解 :
1. B答案的根據在第五段。
2. D 選項 A是這個研究項目的主要宗旨(見第一段的“ unlock the secrets of deadly eruption”)，選項 B是這個研究項目的后續研究項目(見第四段的“ The results can be expanded to anti-disaster research.”)。選項 C是這個研究項目的具體目標(見第三段的第一句)。選項 D文中沒有提到，所以是答案。
3. A答案的根據是第六段的第一句。這一句說到 : “… the meteorological agency monitors 20 dangerous peaks. ” dangerous peaks指的是 dangerous living vocanos。
4. C Mount Unzen高 1486米，而鉆探地點選在海拔 850米的半山腰。
5. A關于本文標題的確切含義在第一段的后半句能夠找到。
