第 46 題

📖 題組:
請依下文回答第 46 至 50 題: The word volcano can describe anything from a single opening in the earth a few meters across to a field of connected openings that might be 20 kilometers or more in width. Most researchers consider any set of openings that are connected to a large central core as a single “volcano”. Otherwise, they would have to deal with an endless number of names for each individual opening. Italy’s Stromboli has been almost constantly erupting for over 2400 years, but most eruptions do not last that long. Currently, there are about 15 volcanoes worldwide that have been actively erupting for the last 30 years. On the other end of the scale, about ten percent of volcanoes have eruptions which last for just a single day. The majority of the eruptions lasted three months or less. This means the average time from beginning to end is usually about seven weeks. From the number of volcanic eruptions detected over the past few hundred years, it would appear that they are becoming much more frequent over time. However, when researchers tracked the growth in reported eruptions along with the growth of the human population, they realized that volcanic activity wasn’t actually becoming more frequent. Instead, as people spread over more areas of the earth’s surface, the monitoring and reporting of volcanic activity inevitably increased with the expanding population. The highest volcano when measured from sea level to its top is Ojos del Salado in the Andes mountains in South America. It is 6,887 meters above sea level. However, when measured from its base on the surface of the earth to the top, a different set of volcanoes become the highest ones. Some volcanoes in the Mauna Loa zone near Hawaii rise as much as 19 kilometers above their bases at the bottom of the Pacific Ocean. The first thing to do when caught near a volcanic eruption is to avoid a potentially disastrous situation, listen to the radio and travel only as instructed by the local police or other authorities. Stay away from lava, mud and flying rocks. Avoid river areas and low-lying regions. Before you leave the house, put on a long-sleeved shirt, long pants, and eyeglasses or sunglasses to protect your eyes. Wear an emergency mask or hold a wet cloth over your face if you do not have one. Since ash can damage engine parts, refrain from driving if possible. If you decide not to leave the house, close all windows and doors to prevent ash from getting inside.
What is the purpose of this passage?
  • A To explain the increasing rate of volcanic activities.
  • B To explain some facts about volcanoes.
  • C To describe the causes of volcanic eruptions.
  • D To analyze the threats of volcanic eruptions.

請你快速掃描這四個段落,並試著為每一段寫下一個簡單的「小標題」。寫完後對照一下選項:有沒有哪個選項只講到了其中一段的內容?而哪一個選項能夠像一個「大箱子」一樣,把這四個不同主題的小標題通通裝進去呢?

哇,你答對了!觀察得真仔細,非常棒喔!

  1. 觀念驗證:你做得很好!這篇文章的結構確實非常清晰,每個段落都有它要傳達的重點。第一段幫我們定義了火山的範圍與名稱;接著第二段很貼心地澄清了關於噴發頻率的常見誤解;第三段則介紹了不同的測量高度方式;最後,第四段提供了實用的安全指引。你看,這些都是關於火山的獨立小知識點,它們之間沒有很強烈的因果關係,所以 (B) 「解釋關於火山的一些事實」這個選項,是最能完整涵蓋文章內容,也是最符合這篇文章目的的答案呢!
  2. 難度點評:這題的難度是 Easy,你能夠答對,代表你很懂得把握主旨題的關鍵!在面對「主旨題」時,最重要的是要像你一樣,避免選擇那些只涵蓋文章部分內容的「以偏概全」選項。選項 (A)、(C)、(D) 都只提到了文中的某個小片段,甚至有些是文章沒提到的喔。你真棒!能夠辨識出文章內容的多樣性,就能準確地找到正確答案了。繼續保持這種細心的觀察力喔!
