托福写作的用词问题一直是很多同学的难题，很多同学们在经过一段时间的练习都很难写作有特色有水平的文章，其实，写作不仅依靠词汇量的积累，也和考生的单词运用能力有很大关系。今天小编就结合实例为大家具体讲解。
托福写作提升用词质量水平改写实例分析
1.Original： We know that sometimes success is measured by how much money you earn.
Revised： It does not surprise us to discover that sometimes success is measured in terms of the money you earn.
点评：know是非常初级的词汇，作文中出现I believe that，I know that这样的表达只能体现考生写作技巧的稚嫩，用It does not surprise us to discover that替换We know that并没有改变原句的含义，却使全句顿时增添了亮点。
2.Original： We all know that most factories would be of no use if there were not clean water supply.
Revised： It goes without saying that most factories would be of no use if there were not clean water supply.
托福写作点评：同上例一样，know这样的初级词汇应避免在作文中使用，It goes without saying that是一个固定结构，意思是"是不言而喻的"，常在作文中用来引经据典或表明一个尽人皆知的道理，类似的表达还有：
An old saying goes that
Proverb goes that
It is universally acknowledged that
It is generally accepted that
3.Original： Some other people think that people should read extensively.
Revised： Another position says that people should read extensively.
点评：同know一样，think也应该尽量避免使用，修改后的句子中是用Another position says that代替think提出另一种观点，也可以用hold a point of view，hold the opinion这样的短语替换。
4.Original： The unexpected win of the match give us confidence.
Revised： The unexpected win of the match boost our confidence.

5.Original： The use of drugs has increased greatly in the last ten years.
Revised： The use of drugs has increased significantly in the last ten years.
点评：greatly是一般用语，表示程度高，"很，非常"，使用相当普遍而没有新意，在托福独立写作中应尽量避免使用这些通俗而又陈旧的词汇，应换用一些更加正式，更有说服力的词语，例如significantly表示达到了非常重要的或可观的程度，"重大的，可观的"，能够具体说明药品使用方面，增长幅度巨大。significantly还可以替换成considerably，tremendously等，同样具有不错的表达效果。
相信通过上面的例句分析，大家对托福写作词汇中的低级词汇都有了一定程度的了解，建议大家在托福作文备考时，还是要积累生活实例、多积累素材、经典句型等，不要只是一种表述方式，一个单词来回换。通过丰富而多样化的用词提升文章质量，这样你的作文才能得到更高的评价。
