作文从句以及用法【五】
在我们所接触的托福写作范文中，包括老托福和新托福的两类，从句在段落中出现的频率都是很高的，尤其是第一段introduction中，一般做背景介绍的时候都会使用宾语从句。
例如：Some people claim that…，在文章的主体部分中，为了体现句式的变化，各种从句交替应用就显得很重要。即使在IBT导入了first draft的概念之后，对文章的内容要求也没有改变要求，需要体现完整性和统一性。
凡事过犹不及，就像美酒再好也不能贪杯一样，从句虽然有很多好处，但千万不要过多重复。虽然从句的优点是简单句不能比拟的，但只有简单句结合从句，才能体现句子的多变性;也只有全部的句子都为主题句服务，文章的整体性才会更好的体现。
以下是议论文写作中比较好的一些从句例子：
1Many experts claim that people should positively participate in garbage recycle.
宾语从句，一般出现在首段背景介绍部分。
2Horror movies, in which there might be bleeding and terrifying scenes, are not recommended for children.
定语从句，一般在主体部分中比较常见，用以解释说明，达到简化句子的'目的。
3As long as you are a student, you should always behave yourself.
状语从句，让步状语从句比较常见的使用although或者though来引导，这里介绍一个使用as long as来引导的句子，这个例句可以解释成“做一天和尚撞一天钟”。
4When it comes to psychology, most people believe that it is a behavioral study.
时间状语从句，例句中的应用表示了“当谈到……的时候”，这是一种美式英语中经常出现的句式，口语和书面语都可以使用，推荐各位掌握。
以上就是在托福写作中从句的用法及重要性，在掌握了从句的正确用法后，我们的托福写作不管在样式上还是在内容上都会有很大改观，离突破托福写作障碍自然也就不远了。最后小编祝大家顺利。
