1. 概念的错误
在写作中，有类词语表面上看似乎是对的,但实际上却没有表达出你想要表达的意思,有时恰恰适得其反。用这类词语写成的英语句子常常引起误解。
① (误)When we go into society after graduation, we will encounter many difficulties.
(正)When we start to work after graduation, we will encounter many difficulties.
“go into society”没有汉语“进入社会”的含义。在西方,它是指一个人到一定的年龄可以开始社会交往,如结交异性朋友,进入某些社交或公共场所等。而汉语“进入社会”一般指学生中学或大学毕业后参加工作。
② (误)Left alone in the jungle at night ,she felt very dangerous.
(正)Left alone in the jungle at night, she felt t hat she was in great danger.
“dangerous”与作者要表达的意思完全相反。说某人dangerous,实际上是说他在某一方面对某人构成危胁,而不是处于危险的境地。这个词用错,意思就完全变了。原意是“她”感到处于危险中。
2、搭配不当
用词搭配是我国学生学英语最感棘手的地方,在雅思写作中，这种错误也是经常出现的，所以希望大家引起重视，因为中文里的某些词语在不同的语境里,英语有不同的说法,而这些说法是约定俗成的,完全是习惯用法所致,我们稍有不慎,便会犯错。现举一些考生在考试中常犯的错误:
① (误)At college, we should learn as much knowledge as possible so t hat we can be well prepared for our future career.
(正)At college, we should acquire as much knowledge as possible so t hat we can be well prepared for our future career.
“学习知识”是学生写作时经常用到的词组,但不少学生都写成learn knowledge,实
际上knowledge是不能与learn搭配的,只能与acquire,obtain,absorb,accumulate,develop,advance,gain,broaden,enlarge,impart,derive，deepen, brush up, digest等词搭配使用。
② (误)In July, they will take part in the final term examinations.
