Question

but while 表示转折,后面能不是完整句子么,直接加名词,我想表达然而不是+名词的意思

Answer 1

ut while 后面不可接名词,

要接完整句子,比如

I have been learning English for many years,but,while I am good in reading comprehension,I still

have difficulty with composition.

I teach at Harvard,but,while a professor,I'm also studying for my Ph.D.in law.

第二句的 while a professor 的完整形式是 while I am a professor ,

I am 被省略了.

另外,but 后面要加逗号

希望帮到了你,

我是加拿大人,我英语老师.
