GRAMMATICAL parallelism – the comparable elements should play the same grammatical role (i.e., they should be written in GRAMMATICAL FORMS that are as similar as possible).

LOGICALLY parallelism – the thing have to BE LIKE EACH OTHER.
？Same priority
？Same TYPE/CLASS OF THING

A duck’s feet are bigger than a chicken. (this sentence implies that the duck’s feet are bigger than a whole chicken)

EXAMPLES:

但实际上句子改错中比较考点的错误常常出现在逻辑和句意上，语法上的错误较少。
