托福写作中differ的用法有哪些?与differ相关的词汇有好些，都是不同的词性，那么具体有哪些用法，一起来看看本文吧。
托福独立写作differ用法介绍
首先我们来看一下differ这个词。在托福写作中，凡是要表示差异区别或是不同的意思时，小编相信大部分考生的第一反应都是和differ相关的词汇，比如difference, differentiation, differentiate等等，而这些词汇在词汇用法搭配上都有所区别。需要大家了解其中差异才能正确运用。
1. 动词differ用法
先来看这一系列词汇中的动词differ，这个动词的意思就是区别于其它事物，基本用法很简单：
a. A differ/differs from B
b. A differ/differs from B to B
c. ____ (多个相似的事物) differ in C
a的意思是A和B不同，例句有：
English differs from Spanish in that it is not pronounced as it is written.
Korean cuisine differs from English cuisine, because it is much spicier.
注意第一个例句中的介词in，指的是两者区别的具体方面，大家可以把第二句也变成带有in的形式：
Korean cuisine differs from English cuisine in that it is much spicier.
b用法的意思是A在不同的B中有区别，光看解释可能不好理解，来看例句：
Laws on pollution differ widely from country to country.
Textbooks differ from school to school.
c的用法其实和b正好倒过来，多个相似的事物放在前面，然后这些事物在C这一方面有所区别，也给大家一个例句参考一下：
Although they are similar in many respects, bonobos and chimpanzees differ greatly in social and sexual behaviours.
2. 另一个动词differenciate用法
和differ相关的另一个动词differenciate，常有考生搞不清楚两者之前的区别，其实除了词性相同以及拥有相似的词根外，differenciate在含义上和differ还是有很大区别的。具体来说，differenciate更强调主动性，也就是主动去区别两者不同的意思，用英文来说就是identify the differences between things。而这个词主要的用法有两个，分别是：
a. differentiate between A and B
b. sth. differentiates A from B
a用法的意思是去区分A和B，注意这里用的是between，因此有着很强的比较对比的意味，来看两个例句：
Joe is color-blind and cannot differentiate between red and green.
The camouflage of octopuses makes it difficult for their predators to differentiate between them and rocks.
b的用法则是指某种特性或者特点让A不同于B，例句是：
The ability to speak differentiates humans from other animals.
Although both whales and sharks are aquatic animals, the fact that whales are mammals differentiates whales from sharks.
3. 名词differrenciation用法
说到differ的名词形式，很多同学可能都会想到differrence这个词，但其实除了它以外，还有一个比较好用的名词是differrenciation。这个词从拼写上就可以看出，其实是上面那个动词differenciate变化过来的，因此作为名词，它的含义和differrence的区别也在于强调主动性，也就是带有主动去辨别区分的含义，比如上面的某个例句，就可以改变成用differenciation来表达的形式：
Joe is color-blind and cannot differentiate between red and green. =>
Joe is color-blind and cannot make a differentiation between red and green.
大家如果还是没完全搞懂的话可以再看两个例句体会一下：
Product differentiation is an important aspect of business.
Companies should work hard to achieve differentiation in products.
