And it's most typical spelling is R as in " rang" , double R as in " married" , WR as in " wrong" and RH as in " rhubarb" .

其最典型的字母（组合）是“rang”中的 R，“married”中的两个 R，“wrong”中的 WR，还有“rhubarb”中的 RH。

So, with a word like " current" , current, it's spelled sometimes double R, sometimes one R, but it's the same sound, really.

所以，对于像“current” 这样的词，current，它有时拼写为双 R， 有时拼写为一个 R， 但实际上是一样的发音。

Again, the little clue, here, is that a lot of these words begin with an " r" , so you end up with an " i" double " r" for these ones, so it helps you to remember which prefix to use.

同样，这里的小线索是，这些单词中有很多都以“r” 开头，所以你最终会得到这些单词的“i” 和双“r”，这样它可以帮助你记住要使用哪个前缀。
