中文写作中学会用些修辞手法自然会让文章增色不少，而托福作文也是一样。在托福作文中恰当的运用修辞会让文章更显活力。托福作文中的修辞手法是比较讲究技巧的，只有恰当使用才会产生意想不到的效果。反之，则是适得其反。而在托福作文中最常见的修辞手法就是比喻，下面就为大家详解一下各类比喻法。
1) Simile（明喻）：It is a figure of speech which makes a comparison between two unlike elements having at least one quality or characteristic in common. To make the comparison, words like as, as……as, as if and like are used to transfer the quality we associate with one to the other. For example, As cold waters to a thirsty soul, so is good news from a far country.
2) Metaphor（暗喻）：It is like a simile,also makes a comparison between two unlike elements, but unlike a simile, this comparison is implied rather than stated. For example, the world is a stage.
3) Analogy（类比）：It is also a form of comparison, but unlike simile or metaphor which usually uses comparison on one point of resemblance, analogy draws a parallel between two unlike things that have several common qualities or points of resemblance.
明喻和暗喻的修辞比较简单，是托福写作常用技巧，在运用的时候想到什么适合的本体和喻体就可以进行“喻”，要修饰什么物体也都可以比喻。总之，托福作文过程中，应该根据文章的内容来施加正确的修饰方法，这样才能令文章更加出奇制胜。
