44.[At times description carries almost the entire burden of explanation.]

Description is most useful in painting a word-picture of something concrete, such as a scene or a person.

45.[Its use is not restricted, however, to what we can perceive with our senses.]

它的用途是不受限的，不過，我們可以用我們的感官去察覺。

We can also describe an abstract concept, such as an emotion or a quality or a mood.

我們也可以描述一個抽象的概念，例如情感、品質或情緒。

But most attempts to describe fear, for instance, still resort to the physical—a “coldness around the heart,” perhaps—and in such concrete ways communicate the abstract to the reader.

但是大多數描述恐懼，例如，一直是採取物理的形容--"寒冷環繞於心"--莫不以此具體方式將抽象傳達給讀者。

Writers can use strokes that will add the dimensions of sound, smell, and even touch.

作家可以使用筆觸來增加聲音、氣味甚至觸感的深度。

Such “strokes,” if made to seem natural enough, can help create a vivid and effective image in the reader’s mind.

這些"筆觸"，如果看起來足夠自然，就能夠幫助創造生動且有效的影像在讀者的腦海中。
