除了名词从句和形容词从句之外，因为它们位置较固定。副词从句中有几种从句位置灵活，可以在主句之前出现，也可以跟在主句之后。通常我们就把这样的副词从句提前，重点则放在后头的主句。
例如：
I came upon an old classmate when I went to town yesterday.
When I went to town yesterday, I came upon an old classmate.
2副词短语更是如此
例如：
Steel is commonly used to make knives, razors and other useful tools because of its durability.
Because of its durability, steel is commonly used to make knives, razors and other useful tools.
3把较重要或有分量的词语放在后头
例如：
That singer's life was tragic and brief.
That singer's life was brief and tragic.
4把句子中一系列的项目作逻辑性的排列
例如：
Tony ate his dinner, watched TV, and then went to bed.
5必要时，重复重要的语词或概念
例如：
...the land stretched out without names. Nameless headlands split the surf; nameless lakes reflected the nameless mountains and nameless rivers flowed through nameless valleys and nameless bays.
再来给大家分享一下反问句的使用，这可是提升写作质量的小技巧!你不信?通我们过官方的评分细节，来说明态度及其反问句使用的意义。首先，我们看看官方对反问句是什么的态度：
The writer's language is fluent, accurate, and varied enough to effectively support the progression and connection of ideas. There is a variety of sentence structures, including rhetorical questions.
显然我们可以了解到评卷人把反问句看做加分点!
我们可以从上面官方给出来的点评得知，反问句的使用确实可以加分。因为通常考生会觉得反问句很难加入写作中，尤其是对论述形式的写作。但我们可以从上面的信息了解到至少评卷人把上述段落中的反问句视作一种句型变化而加以肯定和褒扬。
例如：
In any relationship of mine, I would wish that first of all, the person I'm dealing with is honest.Even though s/he thinks that s/he did something wrong that I wouldn't like,s/he'd better tell me the truth and not lie about it. Later on if I find out about a lie or hear the truth from someone else, that'd be much more unpleasant. In that case how can I ever believe or trust that person again?How can I ever believe that this person has enough confidence in me to forgive him/her and carry on with the relationship from there...
上文的表态的意思可以理解为提出问题不需要回答，而这个问题只是更加强调作者的立场。因此我们可以发现考官对于反问句的使用是非常认同而且鼓励的。考生们也很担心自己写的反问句是不是老外眼中的那种反问句。
因此整理了一下国外关于反问句的定义，如下：
A rhetorical question is a figure of speech in the form of a question thatis asked to make a point rather than to elicit an answer. Though a rhetorical question does not require a direct answer, in many cases it may beintended to start a discussion or at least draw an acknowledgement that thelistener understands the intended message.
通过上文对反问句的定义，我们可以很明确告诉大家，反问句就是这样写的，不要再担心。
其实，除了体现句型变化，合理使用rhetorical question还能帮助我们满足评分标准第一条的要求effectively addresses the topic and task。事实上，反问句不仅能够有效的回应主题，还能强调作者的观点从而获得读者的认同。
所以，反问句的作用总结如下：
Emphasize a point、Persuade powerfully、Influence subtly、Provoke thinking、Help smooth transition
说完句型再给大家分享几句适用于写作中的谚语：
1.a man does not live only by bread.
2.good things stay indoors while bad things will go far away.
3.health is better than wealth.
4.no sweet without sweat.
