SAT平行结构的问题
both 不定式 and 动词 这样平行吗?
Although the candidate made promises both 【to cut】 taxes and 【improve】 services
OC上的一道题 上面这个正确
但是
both the audience and programmers 却是错的
每日一题
所以both.and...不是要保证完全一致吗?

答案

both...and...用于连接两个结构平行的成份.


但也偶有例外,以下句子中就有 “both 不定式 and 动词”：
The following brief notes are indications as to how one might use drama both to stimulate and support work in specific curriculum areas.
The approach was collaborative:teachers were invited to work with the team as equal partners in the attempts both to investigate and find solutions to the GIST problem.
The critics argued that some cut-back or restraint in spending or provision was necessary,both to fund tax cuts and allow for the concentration of resources on the most needy.
