帮忙分析下句子结构和各个部分的成分,尽可能详细点,
How long does it take for a letter to get to America from Beijing?
可不可能有这样的句子
it takes for a letter to get to America from Beijing for 3 days?take 可不可以脱离宾语存在呢？

解答

为说明这个句子成分起见,我把这个句子改成正常语序
To get to America from Beijing for a letter takes how long.
从中可以看出,it是形式主语,真正的主语是不定式短语to get to America from Beijing
句子的谓语动词是take
宾语是how long
for a letter是目的状语.
