1. 我在会上作了重要的关于如何学好英语的报告。

　　误：He gave an important talk at the meeting about how to learn English well.

　　析：此句由于修饰语的位置错放而引起的意思模糊。从句子结构来看，很容易让人觉得修饰语about how to learn English well像是修饰the meeting，但根据汉语句子原意，应该修饰talk.

　　2. 他说了上课迟到的原因，没有人相信。

　　He gave a reason for his being late for school, which nobody believed.

　　析：此句也属于修饰语的位置误放。这种错误的修改法有两种：一是使修饰语紧跟他所修饰的成分He gave a reason，which nobody believed，for his being late for school。二是重复被修饰的成分He gave a reason for his being late for school, a reason which nobody believed.

　　3. 从山上看，我们学校看起来很美。

　　误：Seeing from the hill, our school looks very beautiful.

　　析：非谓语动词seeing与句子的主语our school 不构成主动关系，而是被动的。非谓语动词的错用造成句子的不通顺。因此应该为Seen from the hill, our school looks very beautiful.这是同学们写作中最常犯的错误，应该引起高度重视。
