帮忙分析分析句子成分,
There is a virtual limit on how long we can hope to remain alive,however lucky and robust we are.
不管我们多么幸运,多么健壮,我们所希望的长寿年龄实际上是有限度的.

Answer 1

There is a virtual limit on sth 是主句 ,后面引导宾语从句,介词on后面需要加宾语.
how long we can hope to remain alive,是宾语从句,这个句子后面又有一个让步状语从句however lucky and robust we are.
