前缀 dis- 来源于拉丁语，意为“apart, not”，还有“reverse, intensive”的含义。以 dis-开头的单词大都和介词“from”一起使用。

一、dis-的主要意思：apart

1.分离地，使分离

2.分别

3.远远地，脱离

divert [daɪ'vɜːt; dɪ-] v. 转向；转移; 改道

【记】 [ di-/dis- = apart ; vert = turn 转→”分开转换方向”]

【 英英解释】You can say that someone or something diverts from a particular route or to a particular place.

【例句】 They want to divert the attention of the people from the real issues.

他们想把人民的注意力从真正的问题上转移开。

【短语词组】 ①divert attention from 把注意力从…转移开；分散注意力

②divert from 转移

二、前缀dis-受后面词根的辅音字母影响时，会出现辅音字母脱落和辅音字母同化等变形现象。

1.di- [在辅音字母 g, l, m，r，v 之前]

2.dif- [在辅音字母 f 之前]

differ ['dɪfə] v. 不同 ，相异

【记】 [dif-/dis-= apart 开; fer =carry 拿→" 拿开;互相分离”]

[ differ from 与…不同；区别于…]

【英英解释】 ① If two or more things differ, they are unlike each other in some way. 不同② If people differ about something, they do not agree with each other about it. 有异议

【例句】The story he told police differed from the one he told his mother.
