问题 The only safe way of distinguishing between edible and poisonous mushrooms is to learn to______the individual species.

选项 A、identify
B、classify
C、isolate
D、separate

答案A

解析 本题空格处是说学会识别单独的种类。A项identify“识别”符合题意,如:The markings are so blurred that it is difficult to identify.(标记模糊不清,难以识别。)其他三项classify“分类”,isolate“使孤立”,separate“分离”都不正确。
