SAT写作攻略之语法结构的构成!

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.


概况的表达方式为:

The dairy farm was located in a remote area, 100 kilometers tothe 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.
