虽然sat写作考试的基础是词汇，但是组成文章的基本还是句子，所以多掌握一些常见的，变化很多的句式能对大家的SAT写作能力提升有很大的帮助的。长句、难句或复杂句能够提升文章的语言质量，展示自己“深厚”的语言功底，并因此获得更高的分数。小编今天就为大家讲解一下如何将简单句变成复杂句以及在使用复杂句中我们应该注意的一些问题。
SAT写作变简单句为复杂句有什么方法呢？
1.使用否定的时候，比如：什么对个人不好，对社会也不好。为什么不来个倒装？Never/neither/nor/seldom /rarely/on no account + is…
2.当你想表达“如果怎么怎么样，就是另外一种情况”—虚拟语气。为什么不来个虚拟倒装？Were(Had) it…，something would....。.
3.强调句的使用：It is
people who…/ it is something that…
4.让步句式的使用：“无论什么样的情况下”However[No matter how] whatever[no matter what]等等…。
还有一种Cogent as
this response is, it has some minor errors. Somewhat reasonable as the issue
presents, it does not experience a case-by- case examination.
还有比较常用的although...
It should be admittedly that…，however it does not
follow that.
5.疑问句。用于开头，来个设问句，在自问自答，提出自己观点；用于段中，比如举设想的例子：Can you imagine that…?/ How can one imagine…?
6.定语从句(这个大家一般用的比较熟练，但是注意不要太罗嗦…society where(in which)…,something on which we depend (on
which…based)
7.The
more…the more…句式的使用。人们越幸福，社会越稳定啦、等等。
8.Not
only…but also的使用。很好用的，ETS经典的6分范文：专才VS通才不就用了两个嘛？
9.without的使用。从反面说，很是能够增加字数。还是那篇范文的结尾，就来了两个非常妙的without.
10.还有一些比较常用的：There
is no denying that…/ there is no doubt that…
然而一味地追求句子的长度有时反而会牺牲句子的“可读性”，特别是对一些基础一般的学生来说，有时生硬地追求长句反而破坏了句子的句法准确性，出现错误。我们在使用复杂句中也要注意这些问题：
一：避免空洞的单词和词组
1. 一些空洞的单词或词组更本不能为句子带来任何相关的或重要的信息，完全可以被删掉。比如下面的句子：
When all
things are considered， young adults of today live more satisfying lives than
those of their parents，in my opinion.
这句话当中的“when all
things are considered”和“in my opinion”都显得多余。完全可以去掉。改为：Young adults of today live more satisfying lives than their parents.
2. 有些空洞和繁琐的表达方式可以进行替换，例如：
Due to the
fact that our grandparents were under an obligation to help their parents， they did not
have the options that young people have at this point in time.
“due to the
fact that”就是一个很典型的繁琐的表达方式的例子，可以替换，简化为下面的表达方式：
Because our
grandparents were obligated to help their parents，they did not have the options that
young people have now.
二：避免重复
1. 尽量避免重复使用同样的词汇。或者有的时候虽然词汇没有重复，但意思却有重复。这时候可以做一些简化的工作。例如下面这个例子：
The farm my
grandfather grew up on was large in size.
Large 对一个farm来说就是size方面的large，所以in
size可以去掉，改为：The farm my grandfather grew up on was
large.
更简洁的表达方式为：My
grandfather grew up on a large farm.
2. 有时一个词组可以用一个更简单的单词来替换，例如：
My
grandfather has said over and over again that he had to work on his parents'
farm.
这里的over and over
again就可以改为repeatedly，显得更为简洁：
My grandfather
has said repeatedly that he had to work on his parents' farm.
三：选择最恰当的语法结构
选择合适的语法结构可以使句子意思的表达更为精确和简练。虽然语法的多样性也很重要，但选择最恰当的语法结构仍然是更为重要的考虑因素。以下原则是在考虑选择何种语法结构时可以参考的原则：
1. 一个句子的主语和谓语动词应该能够反映句子中的最重要的意思。例如：
The
situation that resulted in my grandfather's not being able to study engineering
was that his father needed help on the farm.
从意思上来分析，上面这句话需要表达的重要的概念是“grandfather's not being able to study”，而在表达这个概念时，原句用的主语是situation，谓语动词是was，不能强调需要表达的重点概念，可以改为下面这句话：My grandfather couldn't study engineering because his father needed
help on the farm.
2. 避免频繁使用“there be”结构，例如下面的句子：
There were
25 cows on the farm that my grandfather had to milk every day. It was hard work
for my grandfather.
可以改为：My
grandfather worked hard. He had to milk 25 cows on the farm every day.
更简洁的句式为：My
grandfather worked hard milking 25 cows daily.
3. 把从句改为短语或单词。例如：
Dairy cows
were raised on the farm，which was located100 kilometers from
the nearest university and was in an area that was remote.
简介的表达方式为：The
dairy farm was located in a remote area， 100 kilometers
to the nearest university.
4. 仅在需要强调宾语而不是主语的时候，才使用被动语态。例如：
In the fall， not only did
the cows have to be milked， but also the hay was mowed
and stacked by my grandfather's family.
本句不够简洁的原因是本句的重心应该是“忙碌的家庭-my grandfather's family”，而使用了被动语态后，仿佛重心变成了cows和hay。下面的表达方式是主动语态，相对来说更简洁一些：In the fall， my grandfather's family not
only milked the cow but also mowed and stacked the hay.
5. 用更为精确的一个动词来代替动词短语，例如下面这句话：
My
grandfather didn't have time to stand around doing nothing with his school
friends.
Stand around
doing nothing其实可以用一个动词来表达，即loiter：My grandfather didn't have time to
loiter with his school friends.
6. 有时两句话的信息经过组合完全可以用一句话来简练地表达，例如：
Profits from
the farm were not large. Sometimes they were too small to meet the expenses of
running a farm. They were not sufficient to pay for a university degree.
两句话的信息可以合并为下面这句更为简洁的句子：Profits from the farm were sometimes too small to meet operational
expenses， let alone pay for a university degree.
希望大家在SAT作文考试中可以合理正确使用复杂句，为自己的作文添彩。
