你知道VPReview和Review的区别和重要性和难得性么？
你可知Preview和Review的不同？
大家都知道，英语单词中有着无数的单词前缀，大部分都与单词的含义有着直接关联，但其中也有长得很像的“伪兄弟”出现，比如preview和review这两个单词，看着长得挺像，意义却完全不同。
preview
to see or describe something before it is shown to the public;
to show or perform something before it is shown to the public
例：Journalists will be able to preview the exhibition tomorrow
review
to examine, consider, and judge a situation or process carefully in order to see if changes are necessary;
to look again at something you have studied, such as notes, reports etc
例：We will review your situation and decide how we can help you.
同样是view，配上前缀pre或re就会产生不同的意思。那么这两个前缀究竟代表了什么意思呢？
pre-
a prefix occurring originally in loanwords from Latin, where it meant “before” ( preclude; prevent); applied freely as a prefix, with the meanings “prior to,” “in advance of,” “early,” “beforehand,” “before,” “in front of,” and with other figurative meanings ( preschool; prewar; prepay; preoral; prefrontal).
例：
before someone or something;
prewar
in preparation:
Preset the video.
re-
a prefix, occurring originally in loanwords from Latin, used with the meaning “again” or “again and again” to indicate repetition, or with the meaning “back” or “backward” to indicate withdrawal or backward motion:
regenerate; refurbish; retype; retrace; revert.
例：
again;
They're rebroadcasting the play.
again in a better way;
She asked me to redo the essay.
back to a former state.
After years of separation they were finally reunited.
不知道以上这些例子，有没有帮助你加深对于Pre和Re这两个单词前缀的理解呢？如果还有疑惑的话，不妨来看看以下这两个单词的区别：
prepay & repay
这两天你一直在电商网站上做的事情就是prepay；
当你网购过瘾后，就需要准备钱给信用卡repay了。
pre和re也经常被用来加在其他单词前面，改变单词原本的意思，比如：
prelude
如果你听小苹果，前面那一段没有歌词的“动次打次”就叫做prelude。
pre-order
如果苹果公司一拍脑门，决定推出iPhone 7了，你就可以pre-order。
pre-install
如果你买了一台新的电脑， 不用自己装系统就能看到彩旗飘飘，这就叫pre-install。
redo
如果你是设计师，你设计的初稿并不符合客户的要求，就要redo。
reset
如果你的电脑死机了，在热启动无效的情况下只能按下reset。
rename
如果你不喜欢自己的英文名字，比如你叫Rose，但你的死对头却叫Jack，你就可以rename。
最后还是得提醒下你，双11刚过，prepay账单的收货确认将会纷至沓来，还请记得repay你的信用卡。
