主语：France
并列谓语：is 和 faces,用and链接,其实相当于两个句子：France is Europe's tird largest country.Francefaces the UK across the English Channel.
is是系动词,连接的的Europe's tird largest country是表语,face是动词,连接的the UK across the English Channel是宾语
across the English Channel是Francefaces the UK across the English Channel.这个句子中的状语
整个句子的意思是“法国是欧洲第三大国家,隔英吉利海峡与英国相望”
P.S.不是tird是third
