问题     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
【C1】
选项
答案L
解析 语义题。根据词性，此处应当填入形容词。下文中分别从两种角度阐述了人们的观点，语义线索是Some geologists thought…和while others suspected…。表示转折的连接词while提示两派观点相左，所以符合语义的词是conflicting“相矛盾的，冲突的”。故选conflicting。
