【选择】just
【解析】
just 和 only 用在不定式前的区别
just 用于表示“目的状语”的不定式前,意思是“只是为了做某事”,如:
My sister came along just to give me some moral support.我姐姐只是过来给我一些道义上的支持.
He cameover from France last week, just to see us.他上周从法国专程来看我们.
only 用于表示“结果状语”的不定式前,意思是“不料成了做了某事的结果”或“结果却是做了某事”,如:
Ryle came to see her, only to be told that she was in a meeting. 赖尔来看她,却被告知她正在开会.
He raced through the living room, only to find the front door closed.他飞快地跑过起居室,却发现前门锁上了.
本句的意思是“你会不会步行五英里而目的只是看一场电影呢?”,因此不定式 to see a film 是目的状语而不是结果状语.
