考生在托福写作中经常会出现词汇、语法方面的语言表达错误，为了帮助考生避免在写作中出现类似的问题，小编结合实例为大家分析托福写作常见语言表达错误的原因，一起来看一下吧。
一、词汇问题
词汇是写作的基本要素。由于词汇量小，在写作中，考生只能用有限的词汇来表达自己的观点和看法，这就限制了考生写出较高水平的作文。而且稍有不慎，就会出现各种各样的错误。常见的错误类型主要有以下几种：
1. 拼写错误：指文中关键性的单词拼写有误。如：
Nowdays, sience developes quickly. (nowadays, science, develop)
In morden socity, energy crisis becomes seriouce. (modern, society, serious)
As a colege student, he wants to take a part-time job. (college)
要避免这类错误，平时记忆单调时一定要注意词汇的“音”、“形”、“意”，而且在写作过程中要仔细拼写，认真核对，尽量自己发现并改正拼写错误。
2. 选词错误：指表达时误用另一词代替要表达的概念，或指因概念不同而误用他词。如：
He rises his eyes from his work.
She refused to have lunch with her friends.
出现这种错误，主要由于一些考生对同义词或近义词的细微区别不太了解，不能准确辨析并使用意思相近或相同的一组词。
3. 词性误用：指因词类的形式不明确而误用的情况。如：
Work hard and you will be sure to success.
The workers complaint that there are too much work.
有些考生对词汇掌握得不是很牢固，词语误用的现象较为普遍。
4. 单、复数误用：指句子中该用单数或复数形式而用颠倒的情况，也包括短语或句子中前后数的形式不一致。如：
There is many youth here.
Some person say chat love makes the world wonderful.
二、语法问题
这里语法问题指句中时态、语态运用不正确;冠词、代词、介词、连词等误用;句子不完整;另外，还指比较级、非谓语动词及名词单复数等方面的错误。
1. 时态、语态不正确：指句子谓语部分的时态、语态、语气等方面的形式不正确，也包括句中缺少谓语的情况。如：
Great changes are taken place.
He will sure to help me with this question.
2. 冠词误用：指句中漏用、误用、冠词或不定冠词(a、an)的混淆使用情况。如：
He is an university student.
I have never seen such beautiful painting.
3. 介词、代词误用，如
From ray opinion, we'd better leave now.
Please pay attention on what I am saying.
Because his mistake several People died.
The people which called yesterday want to buy the house.
4. 句子不完整：指有的学生因为对句子结构认识模糊，出现只写半句的现象，这也是造成失分的原因之一。如：
Because they thought their wages were too low.
While waiting for their arrival.
5. 比较级使用不当，如：
The world is getting more smaller and smaller.
I like her much than her husband.
6. 非谓语动词的错误使用，如：
Comparing with other countries, China pays little attention to the pollution.
Looking at the top of the hill, the village is beautiful.
7. 名词的单复数形式问题，如：
The good books present us with many useful informations.
