| 释义 |
before ： previously — 153
前者这个词身兼介词、连词和副词三职，因而使用起来很不好辨别；因此，在该用作副词的场合，人们往往改用后者这个副词来代替前者（参见词目 145 和 155 ）。
比较：
Before they had already regarded him as faithful, butnow they were continually suspicious. 过去他们一向认为他忠诚老实，而现在他们对他的疑团久久未释。（在这里， before 用得很不合适。）
Previously they had already regarded him as faithful, but nowthey were continually suspicious. 过去他们一向认为他忠诚老实，而现在他们对他的疑团久久未释。（改用了 previ-ously 显然用得恰当得多了。）
