variety的使用方法

名词“variety”也是大家在论文的书写过程中经常错误使用的单词之一。这一名词有三类用法。下面将对这些用法的特征进行说明。

I. 第1种用法

意思:各种各样、不同的一些、不同种类。

作用:将存在的多种不同一齐指出。

  1. We used a variety of methods to derive these results.
  2. variety of interesting results follow immediately from this theorem.

这里最应该注意的点是,因为“variety”所指的是复数的情况,因此也应该将其作为名词的复数形式来使用。如例句2中,“variety”作为主语的时候,它的动词也应该使用复数

 

II. 第2种用法

意思:多样性。

作用:指出单数或复数的物体所表现出的样子或特性。

  1. The most important point to note here is the great variety of adaptive behavior exhibited within the Microhexura genus.
  2. In this particular case, variety is not necessarily desirable.

第二种用法里的“variety”与其说是复数的不同物体里的某一个体,不如说是将这些复数物体作为一个整体所表现出的“变化”。而这一变化作为一个个体,该用法下的“variety”也就成为了单数名词。又如同例句2里面体现的那样,很多情况下“variety”作为不可数名词来使用

 

III. 第3种用法

意思:种类。

作用:指出不同类型中的某一个。

  1. This variety of chaotic behavior is often seen in strongly perturbed gravitational orbits.
  2. We investigate a variety of mineral deposit usually found only in the presence of large amounts of water.

这种用法下,“variety”作为可数名词的单数形式来使用。
