托福写作选择合适语法结构6大参考原则分享
托福写作选择语法结构原则实例讲解
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，小编就来推荐几种考生们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.

托福写作模板及范文参考：
Should governments spend more money on improving roads and highways，or should governments spend more money on improving public transportation (buses，trains，subways)? Why? Use specific reasons and details to develop your essay.
托福写作范文参考：
Should governments spend more money on improving roads and highways or on improving public transportations? There seems to be a difficult problem since many reasons should be involved. However， after carefully pondering it， I buttress the last one， spending the money on improving public transportation. The reasons are presented below：
There is no denying that improving the public transportation will surely alleviate the pollution given off by enormous cars. If a city has not a developed public transportation， the air will be polluted more heavily. What a dirty environment we will live in! Every day breathing into the air filled with the flour of the gasoline， seeing the sky with the dull color will be the title of our life.
So the essence of environment has been realized by an increasingly number of people， to the governments， the protection of environment is especially an undeniable mission. Another reason I agree with it is that developed public transportation will decrease the frequency of the traffic jams. Perhaps no worse word than “traffic jams” exists， to the businessmen who believe in “Time is money”. Traffic jams not only cost the people time and expense， but also create a bad mood for work. It greatly decreases the efficiency of the whole city. I imagine how can a city whose avenue full of traffic jams develop its economics?
Finally， I want to say that improving the public transportation provide a great number of ways of transportation for most of the poor people who can not afford to buy a car. It is known that our citizens is not made of only people who has the ability to own a car， but the very poor people are also included. I believe that however the technology is improved， the public apparatus should not be ignored， because it serves the people all over the city.
Nevertheless， the private transportation has its own advantages， for instance， it can save a lot of time in some cases， provide some convenience for people. But improving on roads and highways is advantageous only conditionally. Based on the above discussion， I agree with the opinion that the government should spend money on improving public transportation not only it can protect environment and save time for people， but it also can create a convenient environment for all the citizens.

The war between Britain and France
In the late eighteenth century, battles raged in almost every corner of Europe, as well as in the Middle East, south Africa ,the West Indies, and Latin America. In reality, however, there was only one major war during this time, the war between Britain and France. All other battles were ancillary to this larger conflict, and were often at least partially related to its antagonist’ goals and strategies. France sought total domination of Europe . this goal was obstructed by British independence and Britain’s efforts throughout the continent to thwart Napoleon; through treaties. Britain built coalitions (not dissimilar in concept to today’s NATO) guaranteeing British participation in all major European conflicts. These two antagonists were poorly matched, insofar as they had very unequal strengths; France was predominant on land, Britain at sea. The French knew that, short of defeating the British navy, their only hope of victory was to close all the ports of Europe to British ships. Accordingly, France set out to overcome Britain by extending its military domination from Moscow t Lisbon, from Jutland to Calabria. All of this entailed tremendous risk, because France did not have the military resources to control this much territory and still protect itself and maintain order at home.
French strategists calculated that a navy of 150 ships would provide the force necessary to defeat the British navy. Such a force would give France a three-to-two advantage over Britain. This advantage was deemed necessary because of Britain’s superior sea skills and technology because of Britain’s superior sea skills and technology, and also because Britain would be fighting a defensive war, allowing it to win with fewer forces. Napoleon never lost substantial impediment to his control of Europe. As his force neared that goal, Napoleon grew increasingly impatient and began planning an immediate attack.
