谁能帮我分析下句法结构with引导的独立主格,
With you keeping me company,the long journey won't be boring.
you 是主语,keeping是谓语,me是宾语,company是宾补?with是什么?分析时怎么说?
还有一个句子 Help youself to the soup.为什么填youself,

with独立主格结构,keep sb company为固定搭配意为陪伴某人.you 和keep me company为主动,因此用keeping.整个句子意为有你的陪伴,漫长的旅途不会厌倦.help youself to 是固定搭配,意为随便.再问个哈 The most important thing was to find somewhere to stay.to say怎样解释为什么这样填find是实仪动词,动词和动词间需要to隔开,to find somewhere to stay不定式做表语,意为找到待的地方。
