  解題思路：A部分說明了火山活動的作用，正好和iii選項中的火山與地球的特征吻合，因此答案為iii。

  Question 15

  答案：i

  關鍵詞：無

  定位原文：B部分：第1段：整個段落描述了火山爆發的起因。第二段最后：

  These fracture zones, where the collisions occur, are where earthquakes happen. And，very often, volcanoes.

  解題思路：通過掃描這兩個段落，發現其中主要將地球比喻成一個雞蛋，并且由此說明了火山爆發的原因。因此答案應該是i。

  Question 16

  答案：iv

  關鍵詞：無

  定位原文：第2段：Sometimes,it is slow...第3段;Sometimes the magma moves very swiftly indeed. 第4段：The biggest eruptions are deep on the mid-ocean floor.

  劍橋雅思4Test3閱讀解析詳細版Question 17

  解題思路：vi答案是說火山爆發的不可預測性。

  關鍵詞：sections of the earth's crust/volcanic activity

  定位原文：C部分的第4段第2句“...and you can see the rough outlines of what are called tectonic plates--the plates which make up the earth's crust and mantle.”

  解題思路：很明顯，應該是被叫做the tectonic plates。

  Question 19

  答案：magma

  關鍵詞：molten rock from the mantle

  定位原文：C部分第2段第1句：Sometimes it is slow: vast bubbles of magma—molten rock from the mantle…

  解題思路：根據關鍵詞定位，可知答案為magma。

  Question 20

  關鍵詞：Mount Pinatubo/inactive

  定位原文：D部分第1段最后一句：In the case of Mount Pinatubo, this took 600 years.

  解題思路：根據定位句信息可知正確答案是600 years。

  Question 22

  答案：water

  關鍵詞：produce/atmosphere

  定位原文：A部分的第3段第1句：Volcanoes have not only made the continents, they are also thought to have made the world's first stable atmosphere and provided all the water for the oceans, rivers and ice-caps.

  解題思路：火山不僅制造出陸地，也為地球提供了大氣，為海洋、河川和冰帽提供了水。

  Question 23

  答案：magma/lava

  關鍵詞：different types of eruptions /moves slowly

  定位原文：Sometimes it is slow: vast bubbles of magma—molten rock from the mantle—inch to?wards the surface.

  Question 24

  答案：(west) India

  關鍵詞：quickly/horizontally Northern Ireland/Wales/South Africa

  定位原文：C部分第2段第2句：Sometimes—as in Northern Ireland, Wales and the Karoo in South Africa一the magma rose faster，and then flowed out horizontally on to the surface in vast thick sheets. In the Deccan Plateau in western India, …

  解題思路：此處要求填一個地名，根據定位句信息可知正確答案為(west) India。

  Question 25

  答案：explodes

  關鍵詞：third/lava/very quickly/violently

  定位原文：C部分第3段前3句：Sometimes the magma moves very swiftly indeed. It does not have time to cool as it surges upwards. The gases trapped in side the boiling rock expand suddenly, the lava glows with heat, it begins to froth, and it exploded with tremendous force.

  解題思路：這個空要求填一個動詞，而且要注意時態。根據定位句信息可知正確答案為explodes。

  Question 26

  答案：gases

  關鍵詞： magma/emitted

  定位原文：C部分第3段：Sometimes the magma moves very swiftly indeed. It does not have time to cool as it surges upwards. The gases trapped in side the boiling rock expand suddenly,...

  解題思路：emit是“發射，發出”的意思，跟文中的expand屬于同義替換，故正確答案應該是gases。
