狗了一下,"field guide"意思是圖鑑
A field guide is a book designed to help the reader identify wildlife (plants or animals) or other objects of natural occurrence (e.g. minerals). It is generally designed to be brought into the 'field' or local area where such objects exist to help distinguish between similar objects.[1] Field guides are often designed to help users distinguish animals and plants that may be similar in appearance but are not necessarily closely related.
