问题描述:

He went to America﹎﹎﹎some English as well as ﹍﹍﹍.
A.learning;to travel B.learning;travelling C..to learn;travel D.to learn;to travel
为什么选D呢?C为什么不可以?不定式的省略问题啊

He went to America﹎﹎﹎some English as well as ﹍﹍﹍.

分析此句的主要结构是 He went to America ______(填空位置为目的状语)
同时 as well as 是连接 并列结构,由此排除了 A、B、C 三个选项。 

关于to省略的问题, 通常连接的是较为简单地并列结构,to 可以省略 如 to read as well as (to )write some letters ; 但此处 两个目的状语是属于不同事件, 所以后者的to 不省略, 使句子调理更加清晰。

as well as 前后是并列关系,所以选D

这里是因为 as well as要连接两个一样的成分,所以都是不定式
句子中使用不定式是因为表达目的状语
他去美国不仅是去学习一些英语还有旅游

不定式,表目的,他去美国是为了学习英语,也是为了旅游
