比较在雅思考试中极其重要，因为它既考察学生的思维也考察学生语言功底。雅思口语中第三部分经常让我们进行四种对比，古今对比，老少对比，中西对比，男女对比。雅思大作文中论证时有时需要对比论证，从而更好证明论点。A类小作文题目明确要求要make comparisons where relevant。可是同学们关于比较的错误比比皆是。有鉴于此，墨尔本文波雅思创始人文波老师为大家总结了关于比较的学生常犯的7种错误：

7.compare with/comparing with/compared with 乱用一气
Compare with 是谓语动词搭配，例句如下：

Compared with 是过去分词短语，例句如下：

Comparing with 是现在分词短语，例句如下：
