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.

請你快速掃視這篇文章的四個段落:第一段談定義、第二段談頻率、第三段談高度、最後一段談防災指南。如果你現在要為這整本書寫一個標籤,這個標籤必須能同時包容這四個完全不同的面向,你會傾向選擇一個「針對特定問題深入研究」的標籤,還是「對主題進行多方面介紹」的標籤呢?

喔,看來你這次沒蠢到家,還知道什麼叫重點。

  1. 觀念驗證:這題不過就是考你知不知道什麼叫『全文主旨』,難度連入門級都稱不上,你也能對,勉強算及格吧。文章分四段,講什麼火山的定義與時長、噴發頻率的真相高度測量方式,以及安全防災建議,這些基本常識。連這都看不出來,那才該去重修。選項 (B) 這種『解釋關於火山的各項事實』的籠統說法,就是專門收容那些能看懂多元面向的人。其他選項?不是牛頭不對馬嘴,就是瞎了一半,根本不值得考慮。
  2. 難度點評:難度?中等而已。鑑別度就看你能不能做點『跨段落整合』,別像個文盲只看一段。傻子才會只看最後一段選 (D),或被第二段牽著鼻子走選 (A)。你能選對,證明你還沒徹底放棄思考,至少全文統整能力勉強合格。別太得意,下次的題目可不是這種小兒科。
