參考 的英文怎麼說?

[1] refer to something
  read[2] use something as a reference
  use something as a source of information[3] take something into consideration

很多時候用 read 或 use 就夠了，refer to something 可說是「參考」的最佳翻譯之一，如:

For more details on how to maintain the machine, please refer to the instruction manual = 想知道如何維護此機器，請參考操作說明書

Take something into consideration 指把某事當作參考, 不需要遵從.
