When Jules Verne wrote Journey to the Center of the Earth in 1864, there were many【C1】______theories about the nature of the Earth’s interior. Some geologists thought that it contained a highly compressed ball of glowing gas, while others suspected that it【C2】______of separate shells, each made of a different material. Most of our knowledge of the Earth’s interior comes not from mines or boreholes, but from the study of seismic waves (震波) — powerful pulses of energy【C3】______by earthquakes.
The way that seismic waves travel shows that the Earth’s interior is far from uniform. The【C4】______and the seabed are formed by the crust (地壳) — a thin sphere of relatively light, solid rock. Beneath the crust lies the mantle, a very different layer that extends approximately halfway to the Earth’s center. There the rock is the subject of a battle between increasing heat and【C5】______pressure.
In its high levels, the mantle is relatively cool; at greater depths, high temperatures make the rock behave more like a liquid than a solid. Deeper still, the pressure is even more【C6】______, preventing the rock from melting in spite of a higher temperature.
Beyond a depth of around 2,900 kilometers, a great change takes place and the mantle gives【C7】______to the core. Some seismic waves cannot pass through the core and others are bent by it. From this and other evidence, geologists assume that the outer core is【C8】______liquid, with a solid center.
The conditions in the Earth’s core make it a far more【C9】______world than space. Its solid iron heart is subjected to unimaginable pressure and has a temperature of about 9,000 ° F. Although scientists can【C10】______about its nature, neither humans nor machines will ever be able to visit it.
A. way B. ponder C. alien D. iron
E. growing F. harmonious G. speculate H. consisted
I. intense J. exactly K. continents L. conflicting
M. highway N. released O. probably
【C4】
选项
答案
K
解析
continents,词义辨析题。根据词性,此处应当填入名词复数。与该词并列做主语的是seabed“海床”,且根据后句中formed by the crust“由地壳作用形成”,可推测句意“地壳作用导致陆地和海床形成”,故选continents“陆地”。
