两个英语句子分析
1.her visit lengthened as the weeks went by.请分析主谓宾等 还有这里的lengthened怎么理解?是不是可以省略?
2.this once quiet place became vital to the South during the war with the North.其中to the south.north 这里做什么成分（补足语还是定语?）
答
【主】her visit 【谓】lengthened 【状语】as the weeks went by.lengthened谓语动词,时间延长.谓语动词当然不可以省略了.
【主】this once quiet place 这个一度安静的地方 【谓】变得 became 【表语】vital to the South 等于南方至关重要 【状语】 during the war with the North.在与北方交战期间.
to the South 和 with the North 都是介词短语.不是补足语或者定语.
