这个地方危险。
析：danger 是名词，这里误用为形容词。
正：the place is dangerous. 或 the place is in danger.
十一、指代不清
指代不清主要指代词与被指代的人或物关系不清，或者先后所用的代词不一致。
例1：mary was friendly to my sister because she wanted her to be her bridesmaid. 玛丽和我姐姐很要好，因为她要她做她的伴娘。
析：此句让读者无法判断两位姑娘中谁将结婚，谁将当伴娘。
正：mary was friendly to my sister because she wanted my sister to be her bridesmaid.
例2：help yourself to some drink， boys and girls. 孩子们，随便喝些饮料吧。
析：句中的 boys and girls 和反身代词 yourself指代不一致。正：help yourselves to some drink， boys and girls.
十二、间断句子
我们不能把两个或两个以上的句子简单地连结起来，应注意连结时应加上适当的词。
例：there are many ways we get to know the outside world. 我们有许多方式来认识外面的世界。
析：这个句子包含了两层意思：there are many ways 以及 we get to know the outside world，简单地把它们连在一起就不妥当了。
正：there are many ways for us to get to know the outside world.
十三、累赘
