托福写作要想获取输了备考方法格外重要之外，我们还需要了解托福写作的遣词造句方法，本文中北京朗阁小编将为大家讲讲有关托福写作遣词造句方法。
所谓有变化，就是指考生在写作中，一个词好只出现一次，第二次或后几次出现时用其他的词来替换。替换的方法有同义词，语法结构的变化，以及下义词等方法。
1. 同义词
关于老年人的话题在新托福考试中曾经出现过，情况对“老年人”的多样表达：
the elderly, the old, the aged, ageing population, the retired, senior citizens
下面是新托福材料中，摘抄的两段话，非常形象的体现了一个词的多样表达，先看段，请大家注意“奇怪的”这个词在这一段话中的使用：
Certainly no creature in the sea is odder than the common sea cucumber. All living creatures, especially human beings, have their peculiarities, but everything about the little sea cucumber seems unusual. What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by urmets?
又如，在下文中，四个词形式不同，但都是“显著的”意思。
In 1900, the United States had only three cities with more than a million residents---New York, Chica, and Philadelphia. By 1930, it had ten giant metropolises. The newer ones experienced remarkable growth, which reflected basic changes in the economy. The population of Los Angeles(114000 in 1900) rose spectacularly in the early decades of the twentieth century, increasing a dramatic 1400 percent from 1900 to 1930. A number of circumstances contributed to the meteoric rise of Los Angeles.
为了做到用词有变化，朗阁海外考试研究中心为大家列举了托福写作中常用的一些词的同义表达：
同意v : accede to, agree with/on, approve of, consent to, subscribe to, side with
认为v: consider, deem, figure, reckon, believe, think, say, hold, claim, assume, argue, maintain, contend, assert, state, declare
影响n: impact, influence, effect, implication, affection
因素n : factor, contributor, ingredient, element
促进v: enhance, improve, promote, boost， advance, further
培养v: cultivate, foster, develop, nurture
重要的adj: important, critical, crucial, major, essential, vital, main, pivotal
明显的adj: manifest, apparent, evident, obvious
大量的: myriads of, a host of, a multitude of, a great deal of, a vast number of(+cn) , a vast amount of (+un), a plenty of, a wide range of, a great variety of
2. 语法结构的变化
语法的变化指的是，将一个词从语法结构上做一个变化来体现多样性，常见的有词性变化，从句和分词的转变等等。请看下面的例子：
energy consumption = energy which is consumed = energy consumed
the production of ozone-damaging gases
= the amount of gases which are produced to damage the ozone layer
3. 下义词
所谓下义关系，亦称种属关系，就是指几个单词的词义属于另一个词的词义范畴。充分利用下义关系是*单词记忆的好方法，这在复习阶段尤其如此。
1). Color
其下义词有：white, black, red, green, yellow, blue, brown, orange等;
2). Subject
的下义词有：maths, physics, chemistry, politics, Chinese, biology等;
3). profession
其下义词有：doctor, teacher, accountant, president, lawyer等;
4). means of transportation
其下义词有：car, bus, subway, bicycle, ship等。
以上介绍的三种方法对考生的同意转换能力*参考。
