在托福写作中，考生需要学会灵活运用不同的句型和句法结构来展示自己的基本写作技能水平。许多学生经常担心，因为他们不知道如何选择合适的句法结构。下面由新航道的沈阳托福培训小编为您解答！

　　托福写作选择句法结构原则案例讲解。

　　选择合适的句法结构可以使句子意思的表达更加准确和简洁。虽然语法的多样化也很重要，但选择最合适的句法结构仍然是一个更重要的参考标准。以下是考生在考虑选择哪种句法结构时可以参考的几种原则：

　　1. 句子的主语和谓语动词应该能够反映句子中最重要的含义。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.

　　从意义上分析，上述句子需要表达的重要概念是“grandfather’s not being able to study“，但在表达这个概念时，原话中使用的主语是situation，谓语动词是was，不能强调需要表达的关键概念，可以改为以下句子:

　　My grandfather couldn’t study engineering because his father needed help on the farm.

　　2. 防止经常使用“防止经常使用”there be“结构，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.

　　能够改成：My grandfather worked hard. He had to milk 25 cows on the farm every day.

　　更简洁的句型为：

　　My grandfather worked hard milking 25 cows daily.

　　3. 将从句改为句子或单词。例如：

　　Dairy cows were raised on the farm, which was located1000 kilometers from the nearest university and was in an area that was remote.

　　简介的表达方式如下：

　　The dairy farm was located in a remote area, 100 kilometers to the nearest university.

　　4. 只有当需要强调宾语而不是主语时，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.

　　这句话不够简洁的原因是这句话的重点应该是“忙碌的家庭”-my grandfather’s family使用被动语态后，重心似乎变成了cows和hay。以下表达方式为主动语态，相对简洁:

　　In the fall, my grandfather’s familynotonlymilkedthecowbutalsomowedandstackedthehay.

　　5.用更准确的动词代替动词短语，如以下句子：

　　My grandfather didn’t have time to stand around doing nothing with his school friends.

　　Stand around doing 事实上，nothing可以用一个动词来表示，即loiter：

　　My grandfather didn’t have time to loiter with his school friends.

　　6. 有时两句话的信息可以用一句话简单地表达出来，比如：

　　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以下更简单的句子：

　　Profits from the farm were sometimes too small to meet operational expenses, let alone pay for a university degree.
