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?）

答案

【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.
