问题描述

on是介词，为什么后面可以接形容词spoken、written呢？怎么不说成speaking and writing

老师答疑

W老师：

你的句子有错, 应该是:

Fluency in both spoken and written English.

王老师：

我的看法：你可以想想spoken english和speaking english的区别，应该就明白了吧。

黎老师：

Fluency in English both on spoken and written. 

= Fluency in English both on spoken English and (on) written English.

陈老师：

Fluency in English both on spoken and written(=Fluency in Both spoken and written English )=Be fluent in both spoken and written English

在口头英语和书面英语方面十分流利(意思，听说和读写都流利）
