以下戴爾美語老師就下列篇章示範推論及暗示題型的解題技巧

Large sections of North America and Europe used to be covered by ice. About two million years ago, vast sheets of ice moved south. These ice sheets are called glaciers. The glaciers grew and shrunk over the years. This created a series of ice ages. The last ice age ended between 10,000 and 15,000 years ago. Scientists believe an ice age could one day return.
Glaciers form when temperatures are low and there is plenty of snow. The lower layers of snow turn to ice. Then, the ice begins to move. The snow on top slides on the ice underneath.
The largest glaciers today are called continental glaciers. They cover Antarctica and most of Greenland. Continental glaciers can move as fast as 33 meters each day. Smaller glaciers are found in mountains all over the world. These are called alpine glaciers. They move only a few millimeters each day. Glaciers begin to recede when their ice melts faster than new ice forms.
When a glaciers advances, it carries rocks and pieces of ground with it.  This can make a narrow valley broader and deeper. When a glacier retreats, it leaves a U-shaped valley, called a trough. Waterfalls often follow the path of glacial troughs.

1. It can be inferred from paragraph 1 that two millions years ago
(A) a long ice age was coming to an end
(B) there were more glaciers in Europe than North America
(C) most of the glaciers were located in the north
(D) the temperature of the ocean changed

2. What is implied by the information related to glaciers and valleys?
(A) Glaciers cannot enter valleys.
(B) Glaciers cut valleys.
(C) Glaciers follow waterfalls.
(D) Glaciers melt valleys.

【解答】
C/ B

【詳解】
1. It can be inferred from paragraph 1 that two millions years ago
(A) a long ice age was coming to an end
(B) there were more glaciers in Europe than North America
(C) most of the glaciers were located in the north
(D) the temperature of the ocean changed
***托福閱讀解題技巧：About two million years ago，vast sheets of ice moved south. Key words 為 two millions years ago，回原文定位，巨大冰原向南方移動。因此推論出大部分之glaciers 原來是位於北方。因此選擇 C。

2. What is implied by the information related to glaciers and valleys?
(A) Glaciers cannot enter valleys.
(B) Glaciers cut valleys.
(C) Glaciers follow waterfalls.
(D) Glaciers melt valleys.
***托福閱讀解題技巧：When a glacier retreats, it leaves a U-shaped valley, called a trough. Key words 為 glaciers 及valleys，回原文定位，當冰河後退時它會侵蝕切割地表形成U 型峽谷。故而選擇B。
