388. It is one thing to locate oil, but it is quite another to extract and transport it to the industrial centers.

译文　找到石油是一回事，抽出石油并把它输往工业中心又是另一回事。

点睛　locate在此处意为“查找”。one通常与another搭配使用，表示“一个……另一个……”；one还可以跟another连在一起组成短语one another，意为“互相”。如：

The members of the team support one another. 队员们相互支持。

考点归纳　本句包含了一个重要句型：It is one thing to..., but it is quite another to意为“……是一回事，……又是另一回事”。如：

It is one thing to say, but it is quite another to do. 说是一回事，做又是另一回事。

与此类似的表达还有on the one hand...；on the other hand...（一方面……，另一方面……）。如：

On the one hand, I love the freedom of being single; on the other hand, the idea of being married and having a family is very attractive. 一方面，我热爱自由的单身生活；另一方面，结婚成家的念头对我也很有吸引力。
